摘　　要：砾间净化系统中的吸磷滤料、微生物、水生植物对河道水中的TP进行了有效的吸收和转化,利用砾间净化技术在河道内构建原位砾间净化系统,对受到污染的厦门汀溪洪坑段河道水进行净化,保障下游隘头潭国控断面水质达到考核要求。运行情况表明,原位砾间净化系统对微污染河道水水质提升效果良好,工艺出水中TP达到了地表水Ⅱ类标准,有效降低污染物处理的投资成本以及运行成本;同时原位砾间净化系统的构建,解决现阶段微污染河道生态治理征占地问题,也提升了河道的生态景观,具有良好的生态效益和经济效益。The in-situ inter-gravel purification technology can absorb and transform the TP in the river by using the phosphorus absorbing filter material,micro organisms and aquatic plants.This technology contributes the intergravel purification system to purify the polluted river water in the Hongkeng section of Tingxi River,Xiamen to ensuring that the water quality at the state-monitored section of the downstream Aitoutan meets the assessment requirements.The study indicates that the in-situ inter-gravel purification system has a good effect on improving the water quality of slightly polluted river.The TP in the process effluent has reached the surface water Grade II level(the second best level),which provides an effective way to reduces the investment cost and operating cost of pollutant treatment.Furthermore,building the system of in-situ inter-gravel purification can solve the problem of land acquisition for the ecological treatment of slightly polluted rivers,and enhance the ecological landscape.This technology has numerous advantages in terms of ecological and economic aspects.
