The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。

The structure and interface property of hydrated manganese dioxide particles were characterized,and its possible mechanism of pollutants removal was investigated.

The distance between settled releaser and inlet of raw water is 180 cm, and the range of distance between pensile releaser and inlet of raw water is 60-90 cm. The flow of pensile releaser is 2-3 times as much as settled releaser.

较为合理的布置为：固定式释放器S与原水进水口距离为180 cm，悬挂式释放器P与原水进水口的距离在60～90 cm之间。P与S的流量比控制在2～3之间。

A 5. 5h anti-impinge test indicated that the whole technical process had a better anti-impinge ability The feasibility modeling test of water quality showed that the quality of reclaimed water after the treatment by the above process, when used as supplementary circular cooling water and boiler water, met the nation standards in the respect of corrosion, scaliness and bacteria breeding, and even better than the normally used cooling water.

以炼厂实际外排污水为原水，通过两期水力负荷分别为0.2m3/h和0.5m3/h中试规模测试，当本工艺处理水力负荷0.5m3/h、水力停留时间1.49h，污水中COD、氨氮、石油类、悬浮物、挥发酚的浓度变化分别为44.07～102.13mg/l、28.37～50.01mg/l、4.68～19.36mg/l、7.2～34.5mg/l、0.14～0.31mg/l时，平均去除率分别达到94％、96.1％、91.9％、98.2％、100％，出水各项指标均符合循环水补充水水质要求；且通过5.5h抗冲击实验结果显示，整体工艺具有较强的抗冲击能力。

This project used the eligible wastewater from the sewage farm as its raw material, and adopted process of "Floatation + BAC + NF "for advanced treatment and wiping off salts.

该工程以该公司的污水处理场二级出水为原水，采用"混凝气浮+BAC+纳滤"进行深度处理及进行脱盐处理，出水水质超过了当地的自来水指标，已经代替自来水被实际应用于循环水系统的补充水。

Some conclusions were drawn: Oenanthe javanica grew normally when TN and TP concentrations in raw water were 7.05-9.99 mg/L and 0.29-0.73 mg/L respectively; with the hydraulic load being 0.5 m^3/(m^2d), the removal rates of NH3-N, TP, and TN from heavily polluted river water by Oenanthe javanica floating bed were positively related to water temperature, and it inhibited the growth of algae stably; the mean removal rate of nutritive salt increased with the concentration of raw water.

研究结果表明，进水ρ和ρ分别为7.05~9.99mg/L和0.29~0.73mg/L，水芹菜能正常生长，在水力负荷为0.5立方公尺/的条件下，水芹菜浮床对重污染河水中的NH3-N，TP，TN的去除率与水温正相关，对藻类的抑制作用稳定；营养盐的去除负荷随原水质量浓度的增加而增大。

Taking into account the actual situation of the waterworks production,two suggestions were proposed for reducing the formation of trichloromethane one was optimizing the pre-treatment chlorine adding methed and selected a suitable point for chlorine adding;and the other one was improving the effic.

通过分析某水厂水处理过程各阶段水样中的三氯甲烷生成情况，讨论常规水处理对三氯甲烷生成的影响，并结合该厂的生产实际，提出水处理过程中降低三氯甲烷生成的建议：一是优化前加氯投加方式，选择合适的加氯点；二是提高原水浊度的去除率，减少消毒副产物的前驱物质。

That's where water treatment comes into the picture. A water treatment plant purifies the water by adding coagulant that precipitate impurities and particles in the water, allowing it to be flocculated and filtered. Chlorine is then added as a disinfectant before it can properly be called "tap water".

滤水厂将收集到的原水净化，一般都是将凝集剂加入原水中，使混杂於水中的悬浮物凝集成较大的粒块，再经过沉淀、过滤的净化过程，最后加入氯气消毒才能成为「滤水」。

All aspects of the factory were installed at water-line monitoring instruments, according to raw water water quality changes in water automatic adjustment process to ensure that the finished water quality, implementation of dynamic water quality management.

据介绍，上海市委水务局，上海一直是定期水质监测制度的建立原水，中心城区供水企业，工艺水，水等各方面的工厂安装了在水在线监测仪器，根据原水水质水质变化自动调整的过程，以确保出厂水的质量，实施动态水质管理。

I will endeavour to find you some assistance.
