The Research Of Water Quality Controlling When Waste Water Apllied To Circulate Water Treatment

It is well known that fire power generating unit is the enormous water consumer. According to the data, in a fire power plant of 1000WM,even employing the circulating cooling technique, the amount of consuming water equals to the amount of providing water in a middle city with 200,000 residents. The consuming water in a fire power plant, circulating cooling water accounts for absolute proportion, about more than 90% of the total.In order to reduce zhe water usedin zhe power plant,economize the limited water resource, in this paper, the waster water is attempted to as the making up water in the circulating cooling water system of Weifang fire power plant. With the theoretic direction of the water disposal, analyzing the factors of corrosion and scaling, which can effect the units work safely and economically, for using the waster water as the circulating cooling water. On this base, designing and implementing the static experiments and dynamic simulation experiments and industrial experiments on waster water using as circulating water. And determining the controlling ways of water quality under this condition. Finally ,quantitatively analyzing the operating effect from improve water resourse and lifeting of equipments and heat economy etc .Li QingBo(The Engineering of thermal energy)Directed by prof.
