The effluent to be treated comes from various plants of the Steelworks, and contains some domestic sewage. Each plant is operating with different characteristics and timing. The expected effluents will therefore undergo variations in quantity and quality that shall be minimized to optimize the efficiency of the wastewater treatment plant described hereafter.

将要处理的污水来自钢铁厂，其中还包含部分的生活污水。各个工厂的操作具有不同的特点和时间。因此，预计的污水在水量和水质上会有变化，应最大限度地减少这一变化，以优化污水处理厂的效率。

The effluent will arrive into a homogenization and buffer tank after flowing through the coarse and fine screen, and then be pumped to the coagulation and repartition structure.

污水通过粗格栅和细格栅后将进入均化缓冲池，然后由泵提升到混凝配水构筑物。

The buffer tank is designed to have a retention time as long as possible, and it has been finally decided to take 2.5 hours on peak flow of the inlet water

through discussions, and that the tank has to be covered. Raw water lifting shall be provided with flow control to ensure smooth and continuous variations of the flow entering Densadeg, avoiding sudden increase due to start of the pump at full capacity.

缓冲池应具有尽可能长的停留时间，最终经过讨论采用进水峰值流量的2.5小时, 并且要加盖。原水提升备有流量控制，以保证进入高密池的水量是尽量平稳而连续变化的，避免在满负荷时水泵的开启造成水量的突然增加。

The Plant shall be built in one time. The design and implementation of the project shall abide by the following principles :

本工程一次建设，工程设计实施原则：

得利满高密度沉淀池V_型滤池应用技术手册

The frame dewatering machine is fully automatic with working pressure of 1.2 MPa.

板框脱水机为全自动脱水机，工作压力为1.2MPa。

Filter presses are machines that allow the pressure filtration of suspensions, to separate liquid and solids. They are composed of a series of chamber plates covered by filter clothes pressed by an hydraulic jack between a permanent frame and a mobile supporting beam. The plates determine a tight volume in which the under-pressure sludge is pushed.

压滤机可以对悬浮物加压过滤，将固液分离，压滤机由一系列盖有滤布的板框组成，

由一台液压千斤顶在一个固定框和行走路式支撑梁之间压缩，板决定了容量的有限性，加压后的污泥在板内被顶推。

The tightness of the joint faces is assured by an hydraulic group which maintains the balance between the securing of the plates and the pressure of the feed pump during the filtration. Under this pressure liquids pass toward the clothes which retain the solid particles. The filtrates are drained either by taps on each plate or by pipes in the front of the filter press.

由一个液压组件确保接合面之间的紧密性，由液压组件保持过滤期间板的稳定性和进泥泵的压力之间的平衡，在这个压力下，液体流向滤布，固体颗粒被截留，滤出液可以由每块板上的旋塞或由压滤机前部的管道排出。

Feeding pump must imperatively regulate its flow according to the pressure increase, due to cake formation in chambers.

由于在板框内形成泥饼，进泥泵须根据升压调节其流量。

At the end of the filtration, the cakes formed between clothes, are released by the backward movement of the mobile supporting beam and the successive separation of the plates. Control system shall perform full automation to the material treatment process of filter press.

过滤完成后，活动支撑梁向后移动和板的连续分离将滤布之间形成的泥饼排出。控制系统对压滤机物料处理过程实行全自动控制。

The frame press filter has forseen a sluge storage room at the bottom which shall have enough volume for the total sludge produced in one day. Based on the sludge output of 70 tons TDS and 40% as the solid content of the dewatered sludge, the dewatered sludge shall be 145m3 in volume and will be transported to outside by trucks.

板框压滤机底层设置污泥储存车间，可储存一天的污泥量。按污泥产量为70 吨干污泥，经脱水后污泥含固率为40％来计算，经脱水后污泥体积约为145 m3。污泥运输采用汽车外运。

the preparation compartment for mixing with water. From this compartment, the polymer flows to a maturation compartment and to the dosing compartment for proper preparation and dosing. Dosing pumps send the liquid polymer to the respective injection points.

粉末PAM聚合物将用于聚合物的配制和投加。粉末聚合物存放在一个料斗内，一个螺旋进料器从这个料斗内将其加入配制室与水混合。聚合物从该配制室流入饱和室，然后进入投加室进行适当的配制和投加。投加泵将液态聚合物送入相应的投加点。

By adding flocculant, the coagulation effect will be enhanced so as to improve the settling rate.

投加絮凝剂增强混凝效果，提高沉淀效率。
