Sewage discharged at random or half treated can expose seri ous pollution to the water resources. Shiyan City locates in the Northwest of H ubei, in recent years, its industry develops quickly. With the City’s eastward developmen t, the construction step of Suzugamori high-tech development zones and Maojian eco nomic and technological development zones which locate in the west of the City unceas ingly speeds up. Sewage emissions from groups of the eastern city are increasi ng, but the city infrastructure and the construction of pollution control facilities are relativel y stagnant. Large amounts of unt reated sewage and industrial wastewater directly into the Si River (into th e Majia river and Maota river then remitted Si River), which influenced the eastern city sanitation situation very badly, and have a tremendous impact on water safety of the Sout h to North Water Transfer Project’s Water District. As a result, the build ing of a sewage treatment proj ect has e a pressing task. The design based on the hydrological, geolog ical and receiving water materials. It includes the distribution of waster water di scharge system and design of wastewater treatment plant. Specifically, it reasons the c hoice of sewage treatment process and sludge treatment process, the
