垃圾填埋场污泥坑污泥土工管袋脱水应用
|
摘要
针对垃圾填埋场污泥塘治理过程中遇到的高含水率的泥水结合层,采用土工管袋工艺进行处理。工程运行结果表明,SS去除率达到95.78%±0.44%,脱水后污泥平均含水率为82.84%±0.81%,同时对于COD、NH3-N和TP有一定的去除效果,外排水可满足渗沥液处理站要求。对于高含水率的污泥处理有一定实用性。
For landfill sludge pond encountered in the process of governance of high moisture content of the mud layer,using Geo-Tube technology for processing.Project running results show that the SS removal rate up to 95.78%±0.44%,after dewatering sludge moisture content of 82.84%±0.81% on average,at the same time for COD、NH3-N and TP removal efficiency to a certain extent,the drainage can meet the leachate treatment station.For high moisture content of sludge treatment has certain practicality.
