CHAPTER 1第1章

GENERAL INTRODUCTION 简介 P ROPOSE OF SETTLING 沉淀目的

Settling is the separation technique often used for SS and colloids (collected in the form of floc after the coagulation-flocculation stage) removal.

沉淀是一种常用于悬浮颗粒物及胶体（在混凝-絮凝后表现为矾花的形式）分离的工

艺。

L AMELLAE SETTLING 斜管沉淀

For horizontal flow settling tanks, the only basic size factor is the horizontal settling area (SH). A discrete particle is retained if its settling velocity is higher than the Hazen velocity (VH).

对于平流沉淀池，其唯一的基本参数为沉淀面积（SH ）。如果颗粒物的沉降速度大于哈真速度则可以在池中沉淀。

Theoretically, the retention of particles does not depend on the height of the appliance. Thus, in horizontal flow settling, it is theoretically possible to achieve the same results in treating:

理论上颗粒物的沉淀与设备的高度无关，因此下列方法在理论上可以达到同样的处

理效果：

A flow nQ in the same appliance by superimposing n levels of elementary height

H/n

将设备分为n 层则同样的设备可以处理n 倍的水流量。

The same flow Q by superimposing n levels of elementary height H/n and of length

L/n

同样的水流量可以用分为n 层但长度只为原长1/n 的设备处理。

In practice, superimposing horizontal settling tanks without a scraping system does

not allow for efficient sludge removal, and thus leads to reduced performance

实践上，无刮泥系统的多层平流池因不能有效地排泥而降低性能。 The use of lamellae settling consists in multiplying the surfaces of water-sludge separation in one unit. Therefore, positioning lamellae packs (parallel tubes or plates) in the settling zone creates a large number of elementary separation cells. In order to provide for the evacuation of the sludge, it is necessary to incline the lamellae at an angle to the horizontal.

斜管沉淀池中可用于泥水分离的面积为普通沉淀池的数倍，斜管中包含了大量的相

互独立的沉淀单元。斜管应与水平面成一定的夹角以便于排泥。

D ENSADEG BRIEFING高密度澄清池简介

Degremont presents its new Densadeg? system with advanced technology, which could

be used in a vast field of applications, such as the drinking water, wastewater, industrial

water, and sludge treatment. The Densadeg? is a patented settling tank with external

sludge recirculation.

得利满公司运用先进技术开发出崭新的高密度澄清池系统，该系统应用面广泛，适

用于饮用水生产、污水处理、工业废水处理和污泥处理等领域。高密度澄清池带有

外部泥渣回流的专利澄清技术。高密度澄清池亦简称为高密池。

The Densadeg’s success is based on its three technologically complex modules:

高密度澄清池的成功取决于下列三个技术组合模块：

Integrated flocculation zone集成式絮凝区

It is designed for both rapid flocculation with sludge recycling

and slow flocculation for floc growth, and composes 2 reactors in

series:

设计包括带有污泥回流的快速絮凝和矾花增长所需的慢速絮

凝，由两个连续的区域构成：

The 1st is agitated, ensuring fast flocculation by means of an axial flow impeller installed inside a duct providing a homogenous mixing action and the energy

required for flocculation. The flocculent is injected into the base of the turbine (the

coagulant is injected upstream from the Densadeg). External sludge recirculation

continues from the thickener zone to the 1st reactor, thus the high sludge

concentration enhances flocculation performance.

第一级絮凝在一个筒状区域内进行并由一个轴流推进器进行搅拌，以确保快速

絮凝及絮凝所需要的能量。絮凝剂投加在搅拌器的下方（混凝剂投加在高密池

的上游）。从污泥浓缩区到第一级絮凝区进行连续的外部泥渣回流，极高的污

泥浓度提高了絮凝的效果。

The 2nd provides a slow flocculation; the resultant floc has a high level density.

Then water slowly transfers to the settling tank to maintain floc integrity.

在第二个区域中进行慢速絮凝；生成的矾花具有较高的密度。然后水慢速流至

沉淀区以保证矾花的完整性。

Settling zone沉淀区

It is composed of 2 settling sub-zones:

沉淀区由两部分组成：

Hindered settling beneath the lamellar: most of the floc

settles in this area.

斜管下方的成层沉淀：大部分矾花在此区域中沉淀。

Backflow lamellar settling: settling surface area is increased by

using lamellar (hexagonal) modules, used to operate at high

velocities. The residual floc is removed in this module producing

Densadeg ? Clarifier 43

高密度澄清池

the final quality water. 斜管澄清模块：使用协管增大了沉淀面积，用于高速运行。在这个模块中，剩

余的矾花被去除并生产合格的出水。

Sludge thickening zone 污泥浓缩区

Floc accumulates in the base of the settling tank where it thickens in

two superimposed bands limited by the recirculation cone:

矾花沉积在沉淀池底部，并在那里由于回流锥的限制分两层进行

浓缩：

Upper band: the recirculated sludge transit and concentration

zone where the sludge remains for several hours. 上层：回流污泥通过浓缩区并停留几个小时。

Lower band: final sludge thickening before blowdown extraction, contact time of

approximately one week. 下层：在排泥前进行最终的浓缩，停留时间大约为一周。 Sludge is collected by gravity or by a skimmer system equipped with a picket fence in order to promote thickening. A positive displacement pump then routes the sludge to the flocculation zone inlet.

污泥通过重力或一个带有篱栅的刮泥机收集起来。一台螺杆泵将部分污泥回流至絮

凝区。

存放从高密度澄清池底部排出的污泥的污泥池

Flash mixing tank快速搅拌池

The raw water goes firstly into the flash mixing tank and contact with coagulant and lime

for coagulation and decarbonation, a flashing mixer is continuously running in order to

help coagulation and lime softening and prevent floc from settling. A dosing pump (one XXXXXXXXXXX厂操作维护手册

Densadeg? Clarifier 45

on duty, one as standby) injects coagulant into the inlet of tank; another dosing pump (one on duty, one as standby) injects lime into the incoming channel of tank. The pumps are controlled by frequency converters according to raw water flow and desired dosing rates. 原水首先流入快速搅拌池，与混凝剂及石灰接触后进行混凝，一台快速搅拌器连续运行，以帮助混凝和碱度去除反应并避免矾花沉淀。一台投加泵（一用一备）将混凝剂投加到快速搅拌池入口；另一台加药泵（一用一备）将石灰投加到快速搅拌池进口渠道。通过变频器按照原水流量和需要的投加浓度来控制加药泵的运行。Reactor tank反应池

The reactor module is a very important part of Densadeg? system, which determines the results of water and sludge treatment; the adjustment must be done perfectly in the reactor.

在高密度澄清池系统中，反应池模块是非常重要的部分，因为该模块决定了水和污泥处理的效果，所以反应池必须合理地调整。

The doses of chemicals depend on the nature of raw water, the concentration of suspended solids and products of softening. This rate must be determined with the most concentrated inlet water by jar-test (see protocol for jar-test). Following parameters shall be controlled during the jar-test:

药剂的投加量取决于原水的性质、悬浮固体物浓度及软化反应的产物。投加量必须按照浓度最高的进水通过烧杯试验来确定（请参考“烧杯试验”一文）。试验中需控制以下参数：

Temperature, pH, turbidity, SS, colour, alkalinity etc. of raw water

原水的温度、pH、浊度、固体悬浮物、色度、碱度等

Optimal pH

最佳pH值

Optimal doses of reagents

最佳投药量

Sludge production

产泥量

Reactor turbine speed反应池搅拌器速度

The rotation speed of turbine is designed to ensure a good mixing of the polymer and a good flocculation. If the rotation speed is too high, the flocs run the risk of breaking; too low, sludge may settle down inside the reactor.

搅拌器的转速应确保聚合物搅拌充足和絮凝良好。如果转速过高，那么矾花就有被打碎的危险；太低则有污泥在反应区内沉淀的危险。

Sludge recirculation污泥回流

The purpose of the sludge recycling is to improve the floc growth and to increase the density of the floc.

污泥回流的目的在于加速矾花的生长以及增加矾花的密度。

高密度澄清池

46Operation & Maintenance Manual for XXXXXXXXXXXXXX

Settling tank沉淀池

The settling tank is a very important part of the system in which most of the floc settles

and thickens. Thickening is promoted by continuous scraping of the precipitated sludge.

Part of the sludge is recirculated into the reactor. This perfectly controlled external sludge

recirculation is designed to maintain the high sludge concentration required for

homogeneous flocculation. Lamella modules are located at the top of the tank, in which

the residual floc are removed and the final qualified water is produced.

沉淀池是高密度澄清池系统中重要的部分，大部分矾花就在这里沉淀和浓缩。连续

刮扫促进了沉淀污泥的浓缩。部分污泥回流到反应池中。这种精确控制的外部污泥

回流用来维持均匀絮凝所要求的高污泥浓度。斜板模块放置在沉淀池的顶部，用于

去除剩余的矾花和产生最终合格的水。

投加了混凝剂和石灰的原水先流入反应池中，在该池中进行絮凝反应、暂时硬度的

剩余的矾花将在斜管中去除并产生最终合格的出水。

Part of settled sludge is recycled to the reactor by an external pump, the extra sludge pre-thickened at the bottom of settling zone is evacuated to sludge storage tank through another pump
