Application of MBBR+DAFProcess in River Water Purification Project in Jurong City
In order to solve the problem of water pollution of Heping River in Jurong City from unknown pollu-tion sources,the water purification project of Heping River was constructed.The design scale of the water purifi-cation project is 1X 104m3/d;the design process is MBBR+DAF(dissolved air flotation system),and the main in-dicators of the designed effluent are in accordance with the Surface Water Environmental Quality Standard(GB 3838-2002)Class Ⅲ water quality standard.The project uses enamel assembled tanks and prefabricated contain-ers as the main structure.The construction period is compressed to less than 2 months,and the construction cost per ton of water is reduced to about 650 yuan.By streamlining the auxiliary process and optimizing the process combination,the project covers an area of 1300m2 and the operating cost reduces to about 0.85 yuan/ton.From the perspective of operation,although the inlet water quality fluctuates greatly,the effluent of the purification system can generally meet the standard.After the completion of the project,the water quality of the Heping River and its downstream sections has been effectively improved,which provides a technical reference for the emergency water quality guarantee project of urban rivers.
