摘要
在广东某山溪性河道支流建设了生物接触氧化原位修复工程,采用砾间接触、碳素纤维生态水草、水生植物、生态过滤坝组合技术。系统对CODcr、NH3-N、TP的平均去除率分别达到42.20%、50%、35.20%,削减量分别为14.4kg/d、0.55kg/d、0.12kg/d。
A biological contact oxidation in-situ remediation project was constructed in a tributary of a mountainous river in Guangdong Province,using the combination technology of gravel contact,carbon fiber ecological aquatic plants,aquatic plants and ecological filter dam.The average removal rates of CODcr,NH3-N and TP are 42.20%,50%and 35.20%respectively,and the reductions are 14.4kg/d,0.55kg/d and 0.12kg/d respectively.
