Study On The Development Of Water Treatment Agents For The Circulating Cooling Water Of Power Plant Reusing Municipal Sewage

When municipal wastewater is reused for the circulating cooling water system of thermal power plant,some problems such as scale,corrosion and microbe incresing will be generated which seriously affect the normal running of circulating cooling water system.In this research we did a lot of experiments in order to develop an environmentally friendly and excellent performance water treatment agent.Firstly, we analyzed the municipal secondary effluent quality, and judged the trend of scale and corrosion.Then,we did a lot of static experments in order to find out a compound scale inhibitor and a compound biocide most suitable for recyling cooling system of thermal power plant which municipal sewage is reused. At last, we did dynamic analogous experiment and generally evaluated the characters of the compound agents, and finally deduced that the compound agents can well solve the scale, corrosion and microbe problems of recyling cooling system which municipal sewage is reused directly. The water treatment agent which we developed has a certain theoretical significance and practical value for solving water shortage problem.
