-
Rapid wastewater treatment technology using sedimentation integrated rectangular airlift loop reactor (RPIR) is a new type of rapid biochemical sewage treatment technology. For the solution of the inadequate sewage treatment capacity and lack of water replenishment in the water bodies of the Shawan River in Shenzhen, a new 10 000 m3/d emergency sewage treatment station was designed with RPIR to achieve on-site treatment and in-place water replenishment. The results showed that RPIR had the characteristics of small occupation, low investment, fast start-up, and stable effluent, and the effluent index could stably reach the first-level A standard. It demonstrated that RPIR could be a promising technology to apply in worldwide for the efficient treatment of polluted water and ecological on-site water supply.
