Ocean disposal of sewage is prohibited or effective measures to limit emissions and freedom of sewage shore random row, concentrated pretreatment of sewage works system, transportation by pipeline to the underwater depth of the ocean, emissions by the diffuser, so that inas small as possible within a high degree of dilution, to reduce the impact on the environment. This sewage marine disposal engineering, compared with the conventional secondary treatment of sewage, saving 1/2 to 1/3 of investment in infrastructure and operation and management costs, covering 30 to 40 percent reduction in benefits are enormous.
海洋污染英文口头报告作文
海洋污染英文口头报告作文英文：Marine pollution is a serious issue that affects our oceans and the creatures that live in them. There are many different types of marine pollution, including oil spills, plastic waste, and chemical contamination.One of the most devastating forms of marine pollutionis oil spills. These spills can have a catastrophic impact on marine life, destroying habitats and killing off entire populations of animals. For example, in 2010, the Deepwater Horizon oil spill in the Gulf of Mexico killed an estimated 1 million birds and 5,000 marine mammals.Another major source of marine pollution is plastic waste. Every year, millions of tons of plastic end up in our oceans, causing harm to marine life and ecosystems. For instance, sea turtles often mistake plastic bags for jellyfish and ingest them, leading to blockages in theirdigestive systems and ultimately death.Chemical contamination is also a significant problem in our oceans. Industrial waste, agricultural runoff, and sewage all contribute to the presence of harmful chemicals in our waterways. These chemicals can accumulate in the tissue of marine animals, leading to health problems and even death.中文：海洋污染是一个严重的问题，影响着我们的海洋和生活在其中的生物。

保护海洋的英文演讲稿
保护海洋的英文演讲稿Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth, too. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.What are toxic wastes?Toxic wastes are poisonous materials that are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans. When toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. In the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.Many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. One of the most harmful chemicals in the ocean is lead. Lead can cause many health problems. Itcan damage the brain, kidneys, and reproductive system. Lead can also cause birth defects for people. It has been shown to cause low IQ scores, slow growth, and hearing problems for small children.House and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.Many things found in the ocean may cause seafood to be dangerous to human health. The effect on humans from contaminated seafood may include birth defects and nervous system damage. Medical waste found in the ocean is being tested to see if swimmers have a chance of developing Hepatitis or AIDS. Other waste has been known to cause viral and bacterial diseases. This type of pollution can be stopped by watching what pollution we are letting into the ocean. People are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.Boating Pollution Prevention TipsWhenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life.Boating pollution is the pollution that comes from the boat’s engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. The engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. In order to make as little pollution as possible, what everyone can do tohelp is: Only turn a boat engine on all the way when you need to. Don’t take your boat out into the water if you don’t need to. Be sure to store and transport gasoline in places where there isn’t any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air. Every year, buy new or cleaner marine engines for your boats.Garbage DumpingGarbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. Most of the waste that has been dumped into the ocean in the early 1990’s is still there today. One main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. Rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. After that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animal’s neck, causing it to suffocate), and makes the water dirty.。
海洋污染英文口头报告作文
海洋污染英文口头报告作文Well, let me tell you about ocean pollution. It's a serious problem that affects not only marine life, but also humans who rely on the ocean for food and recreation.One of the biggest culprits of ocean pollution is plastic. Every year, millions of tons of plastic waste end up in the ocean, harming marine animals who mistake it for food or get entangled in it. It's a heartbreaking sight to see a sea turtle with a plastic straw stuck in its nostrilor a bird with a plastic ring around its neck.Another source of ocean pollution is oil spills. Whenoil spills occur, they can have devastating effects on marine life and ecosystems. Oil can coat the feathers of birds, making it impossible for them to fly, and it cankill fish and other marine animals by suffocating them or poisoning them.Chemical pollution is also a major problem in the ocean.Chemicals from agricultural runoff, sewage, and industrial waste can contaminate the water and harm marine life. Some chemicals can even bioaccumulate, meaning they build up in the tissues of animals over time, leading to health problems and even death.Overfishing is another issue that contributes to ocean pollution. When fish populations are depleted, it can disrupt the balance of the ecosystem and lead to the collapse of certain species. It's important to practice sustainable fishing practices to ensure that we don't deplete the ocean's resources.In conclusion, ocean pollution is a serious problem that requires immediate action. We need to reduce our use of plastic, prevent oil spills, regulate chemical use, and practice sustainable fishing practices. It's up to all of us to protect the ocean and the life it supports.。

保护海洋英语演讲稿保护海洋的英语演讲稿Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.I need to describe the problem. Our ship currently dumps all its rubbish into the sea.Its easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly.A case in point is that we should stop providing plastic bags.We must act now before it is too late!有关保护海洋的英语演讲稿The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.In fact over 80% of all marine pollution comes fromland-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.保护海洋英语演讲稿范文Future marineKnow you today from the 20xx, let me do a return tour, you tour in 2030 with the Ocean, I think you must be harvested.

海洋污染的英语演讲稿3海洋污染英语演讲稿Sea pollutionBetween 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2023, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2023.Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.。

Ｉt is my duty to protect the marine environment and regularly check the marine ecology.Ｏne morning, Ｉ and two members of the group as usual sit on patrol boats to the Ｓea Ｐatrol, when our ship sailed to the coast of Ｎew Ｓouth Ｗales, Ａustralia Ｙamuba, seawater test system suddenly issued a "beep beep." Ｔhe sound of the alarm, Ｉ hurried out of the computer monitor image viewing, a look at the screen and Ｉ was shocked, usually blue sea disappeared, a layer of white foam accumulation in the sea, with the waves rising and falling, like a great bath bubble bath. Ｔhe turbidity of foam water toward the beach, rushed against the shore of the vacationers, people fled in panic. Ｗhat happened? Ｗhat's the white one? Ｗhy is that? Ｗill there be any danger? Ａ series of questions appeared in my mind. Ｉ'll report the danger to the superior and tell us the situation immediately. Ｉn order to find out the reason we decided topersonally take some foam samples, entered into "cappuccino" of the sea, and my team members are niezhao Ｋhan, Ｉ do not know the unknown material much harm to the human body. Ｗe wear the blue suit, wearing a long plastic gloves and protective environment, holding two experimental glass bottles, dive under the sea, Ｉ found the sea under the sea is deep blue, the water turbidity than usual, only white foam floating on the sea surface, there is nothing to stimulate the taste. Ｗe soon picked up the sample and sent a signal to the headquarters waiting for the experts to arrive.Ａfter a careful examination of experts, found that the unknown white foam, is due to a large number of fresh water from the river flows into the ocean, and the ocean pollution (waste plastic products, such as rotten fish and seaweed and so on) the interaction of the formation, in addition, the region is experiencing strong airflow. Ｔhe formation of huge waves in the sea, the water makes the bubble rapidly upward rotation, and gathered on the shore, the bigger wave bubble more, not particularly harmful to human.Ｔhat expert conclusion, our heart is considered hanging down, but my heart is still a widespread concern, now marine ecological situation is not optimistic, the reason is verysimple, is that people who do not own endless destruction, there are almost daily reports, the factory and the pollution of the river, the red tide every year rujierzhi.

Ｉ am increasingly worried that small life in the sea will be hurt, worried that seabirds lost their homes to live, and that one day people will be punished by nature.Ｔhe selfless help us, but we in turn destroy it, this is not the teacher taught us the story of ingratitude? Ｔherefore, we must not forget the contribution of the sea, we should take good care of it, and treat it as a mother, care and care. Ｗhen we hurt it, we should feel guilty and should make more compensation.Ｐrimary small power is not small, we can start from little things, such as the usual pocket money saved up to protect marine funds, while on holiday to the seaside to pick up trash, can promote the protection of the ocean to the side of the man's knowledge......
