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。
