28、influent flux and quality, and the influent water quality data previously listed out.3.1.3 处理出水技术指标：见前页。 Effluent water quality index is previously listed.3.2 工艺设计 Process Design3.2.1工艺流程简介 Process Introduction：对比原水水质情况，工艺推荐选择工艺成熟、操作方便、运行操作费用低的除盐水处理系统，采用预处理+超滤+特种分离膜工艺。水处理系统先用原水泵将原水送入纤维球过滤器，再经过特种树脂吸附

29、柱，然后进入超滤装置，超滤出水投加阻垢剂，使预处理产水满足特种分离膜进水要求，并防止浓水在特种分离膜的一侧结垢，再进特种分离膜系统除去盐分，使产水达到设计要求。The feed water is first pumped into the fibrous wadding filter, then through the special resin adsorption column, and then into the ultra-filtration device. Antiscalant is dosed into water flow after ultra-filtration to

30、avoid precipitation and formation of deposits so that pre-treated water can meet the specific membrane separation system requirements.

35、ank: It is used to store the feed water. Thus the the fluctuations of feed water fluxes can be regulated to avoid their impact on our system.Water level control devices are installed in the feed water tank. They are used to monitore the water level in the feed water tank and to control the feed wate

36、r lifting pumps.3.3.2 浓水收集池-反冲洗水池（业主自备或提供）：收集特种分离膜浓水，用这部分水可以冲洗纤维球，节省运行费用。浓水池的容积建议选用100m3。Concentrated Liquor Collecting Tank (Owner or Razan provides): It is used to collect concentrated liquor from specific membrane separation system. This part of concentrated liquor can be used to wash the fibrous

37、 wadding filters. The volume of concentrated liquor tank will be about 100m3.3.3.3 预处理反洗水泵：为过滤器反洗提供所需要稳定的水压和流量。Back-washing Pumps for pre-treatment: used to provide steady hydraulic pressure and flux for filters back-washing.3.3.4 原水增压泵：为后续设备提供正常工作所需要稳定的水压力和水流量。考虑该系统原水中含有杂质，系统选用东方泵业的增压泵，该泵具有运行稳定、平稳、

38、噪音小等优点。Feed Water Lifting Pumps: used to provide steady hydraulic pressure and flux for following facilities. East pumps are adopted in this system. East pumps run steady and have little noise.3.3.5 预处理过滤器：纤维球过滤器（FWF）主要利用纤维球作为滤料，去除原水中的泥沙、悬浮物、胶体、油类等杂质，对原水进行初步净化，达到后续设备的进水要求。多介质过滤器选择较低的运行滤速，以降低进水的浊度并保证

39、过滤出水污染指数SDI154。该滤料具有高弹性、空隙可变、耐磨损、抗腐蚀等特点。在过滤过程中，滤层空隙率沿水流方向逐渐变小，符合理想滤料上大下小的孔隙分布。整台设备紧凑。占地面积小。构造合理，处理效率高。过滤器工作一段时间后，其进出口压差增大，需要进行反洗，以恢复滤料的过滤效果，反洗周期为3-7天。反洗时采用气水反冲洗。将滤料表面粘附的泥球杂志打散并剥落下来，然后用水冲走，提高过滤器的反洗效果。反洗过程及时间：第一步：松层5min、第二步：排水3min、第三步：气擦洗5min、第四步：气水反洗5min、第五步：反洗20min、第六步：正洗10min。反洗以压力参数设置来控制反冲洗周期，当运行到

40、进水与出口压力差达到0.507kg/cm2时即停止运行进行反冲洗。反洗水强度应使滤层膨胀1525%。反洗时送入压缩空气，擦洗滤料，其强度为1825L/sm2。本方案设置2台直径为2000mm的立式纤维球过滤器，单台进水量50m3/h，过滤器内填纤维球。过滤器装配有进口Burket气动蝶阀，通过控制盘的自动或手动控制，可分别实现反洗、正洗、运行的状态切换。Pre-treatment Filters: Fibrous wadding filters use fibrous wadding material as the filtration medium. It can remove bedloa

41、ds, suspended solids, colloids and part of organics; the feed SDI is also reduced and thus the feed water can meet the requirements for the following facilities.After a certain working period, the pressure gap of the wadding filters will increase, and the filters should be back-washed to regain bett

42、er working efficiency for the fibrous wadding filters. Back-washing periods last 3 to 7 days. Back-washing process: loosing; draining; air washing; air-water back-washing; back-washing; washing.In the present scheme, two fibrous wadding filters each with 2000mm-diameter and 50m3/h feed flux will be

43、used. Automatically or manually-controlled Burket pneumatic butterfly valves will be mounted on the filters. This type of valve can switch between the states of back-washing, and washing and running.3.3.6 气源：采用空压站气源，在多介质过滤器反洗时使用。Air Pressure Source: Air pressure will be supplied by the air compresso

44、r, and will be used for fibrous wadding filters.3.3.7 特种树脂吸附柱：纤维球过滤器出水进入特种树脂吸附系统。因原水中含有一定量的挥发酚、石油类以及其他有机物质，如果进入膜处理系统，会产生细菌滋长，因此需去除此类有机物质。吸附树脂是一种不溶于酸、碱及各种有机溶剂的有机高分子聚合物吸附剂，应用大孔吸附树脂进行分离的技术是继离子交换树脂后的分离新技术之一。大孔吸附树脂的孔径与比表面积都比较大，在树脂内部具有三维空间立体孔结构，具有物理化学稳定性高、比表面积大、吸附容量大、选择性好、吸附速度快、解吸条件温和、再生处理方便、使用周期长、宜于构成闭路循

45、环、节省费用等诸多优点。本废水处理系统中的特种树脂选用美国RohmHaas吸附树脂，这是一种高交联度、高比表面积、不带有官能团的非极性聚合物吸附剂，其化学稳定性好，使用寿命长，抗生物污染。其连续的聚合物相和连续的孔结构赋予其优异的吸附性能，此种树脂TOC的去除率可达到90%以上。吸附系统吸附饱和后再经过洗脱液洗脱，TOC的洗脱率可达到99%，因此能够保障树脂吸附系统的去除效果和正常运行。当交换柱的流出液中残存的物质浓度超过规定指标时，树脂已饱和，需要进行再生，为下一个交换过程创造条件。树脂再生后，树脂层内残存的再生剂用产品水进行正反洗。Fibrous wadding filter efflue

46、nt flows into the special resin adsorption column. The raw water contains a certain amount of volatile phenol, petroleum and other organic substances, and if they go into membrane systems, it will bring about the growth of bacteria. Therefore, it is needed to remove these organic substances.Adsorpti

47、on resin is a kind of organic polymer adsorbent non-soluble into acid, alkali and various organic solvents. The application of macroporous adsorption resin is one of new separation technologies after ion exchange resins. The pore size and surface area of macroporous resin is large, and has a three-dimensional space within pore structure, with the stability physical chemical and h
