Study On The Influence And Removal Of Turbidity To The Reclaimed Water Reused In The Cooling System

Urban sewage after advanced treatment for water consumption to large, low water requirements of industrial water, is to solve shortage of water resources, make full use of a large quantity, concentration, quality and quantity of relative stability of the urban sewage and reduce sewage discharge on the environment pollution and achieve a good way to increase income and reduce expenditure.This paper relies on a thermal power plant in the Beijing area in the water reuse project, targeted at the plant for recycling water to the cooling water system caused by high turbidity problems, research by the high turbidity of the water treatment system for the effects generated by Impact and solve the problem of high turbidity feasible treatment options.This experiment in view of the "reclaimed water" quality that reused as a cooling tower makeup water, analyzes it the influence which produces to the system. Based on the current water treatment plant used by the amount of usage, focuses on the introduction of water after water turbidity too large circle phenomenon, through the pilot study under conditions of high turbidity of the water cycle used by the inhibitor, fungicides, and other water treatment The effect of the impact on the turbidity of the cooling water systems. In the experiment discovered that when the system turbidity is higher than 10NTU, the corrosion inhibitors and the role of microbicides effect become worse.Finally, the laboratory-scale experiments and tests on the scene to remove the turbidity of the method, using double-layer media filter can effectively remove the turbidity and phosphorus, solve the turbidity high problem.
