Abstract: |
Adopt two-stage biological contact oxidation process to treat the domestic sewage of some ecotype residential district in Shijiazhuang, China. Results show that this technology has the less floor space and simple operation management, and the effluent can match the requirement of “The reuse of urban recycling water- water quality standard for scenic environment use” (GB/T18921—2002)[1] in China. And the effluent can be used for afforestation, vehicle washing and landscape water. The whole operational cost is 0.91 Yuan/m3, and the economic benefit brought by project investment is 321 thousand Yuan each year. So the benefits of social, environmental and economic are all significant.
