More and more domestic sewage, we must take effective measures to recycle waste. Because of the unique topographic structure of Jinan, the topography is high in the south and low in the north, resulting in the surface water and groundwater gathering to the urban area. A sewage treatment plant with a daily treatment capacity of 30000 m3 is needed to select the CASS process according to the characteristics of incoming and outgoing water quality. The process mainly includes the main reaction zone and the pre-reaction zone. The main reaction zone is operated according to the program cycle of aeration, reaction, boiling water and idle.The sludge was dewatered by gravity concentration tank, and the treated sewage was treated by contact sterilizing tank. According to the theoretical simulation of wastewater from influent to effluent, the m...
