快速污水处理技术（RPIR）用于深圳水环境治理

为解决深圳沙湾河黑臭水体治理中污水处理能力不足、缺乏补水的问题，设计采用 快速污水处理技术(RPIR)，在短期内新建一座1×10⁴ m³/d的应急污水处理站，实现就地处理就地补水。运行结果显示，该工艺具有占地省、投资低、启动快、出水稳定等特点，出水指标可稳定达到一级A标准，可为其他地区实现污水处理快速建设快速达产、就地实现生态补水提供借鉴。

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.
