RCERP（Reverse Circulation Ecological Reaction Pool）型逆向循环生态净化塘是将处理水进行逆向循环与培育净化性能优良的沉水植物净化水质相结合的系统工艺。利用植物自身的光合作用和化感作用完成生态修复，其特点为 1. 投资省，因地制宜，无需雨污分流；2. 无需清淤，污水资源化，淤泥成为植物的营养供给者；3. 无需截流，适用于开放性水体，可处理 COD 在 200 以内的水体及暴雨时前十分钟水体，被破坏的生态体系待稳定后可自行恢复。
该技术不投加任何化学药剂，出水水质可达到《地表水环境质量标准》（GB3838-2002）Ⅲ 类标准。
RCERP (Reverse Circulation Ecological Reaction Pool) type reverse circulation ecological purification pond is a system process that combines the reverse circulation of treated water with the cultivation of submerged plants with excellent purification performance to purify water quality. It uses the photosynthesis and allelopathy of plants to complete ecological restoration, with the following characteristics:
Low investment, adapting to local conditions, and no need for rain-sewage separation;
No need for dredging, realizing sewage resource utilization, with sludge serving as a nutrient supplier for plants;
No need for interception, suitable for open water bodies, capable of treating water bodies with COD within 200 and water bodies in the first ten minutes of rainstorms. The damaged ecological system can recover by itself after stabilization.
This technology does not add any chemical agents, and the effluent water quality can meet Class Ⅲ standards of the Environmental Quality Standards for Surface Water (GB3838-2002).
