Rural sewage treatment and sludge and phosphorus resource utilization method and system
The invention discloses a rural sewage treatment and sludge and phosphorus resource utilization method and system, relates to the technical field of rural sewage treatment, and aims to solve the problems that sludge in a sludge concentration tank in an existing rural sewage indirect resource utilization system is not effectively utilized in situ, and phosphorus resources are also wasted. According to the invention, rural domestic sewage is pretreated, large-particle impurities are filtered out, the treated rural domestic sewage is sent to a biological treatment unit after being treated by an adjusting tank, and effluent of the biological treatment unit is introduced into an artificial wetland for continuous treatment, and then reclaimed water is recycled; residual sludge discharged by the biological treatment unit is discharged into a phosphorus adsorption tank, the sludge subjected to phosphorus removal enters a sludge concentration tank to be concentrated, the concentrated sludge is made into ceramsite to replace ceramsite filler in the constructed wetland and the phosphorus adsorption tank, and the replaced phosphorus-containing ceramsite serves as fertilizer to be returned to the field; the process steps are simple and reasonable, the cost is low, sewage treatment is proper, the ceramsite prepared from the sludge can be used as a farmland fertilizer after adsorbing phosphorus, and in-situ utilization of the sludge and phosphorus can be effectively achieved.
本发明公开了一种农村污水处理及污泥和磷资源化利用的方法及系统，涉及农村污水处理技术领域，为解决现有农村污水间接资源化系统中污泥浓缩池污泥未有效原位利用，且磷资源也被浪费的问题；本发明将农村生活污水预处理并过滤掉大颗粒杂物，再经过调节池处理后，送入到生物处理单元，将生物处理单元的出水引入人工湿地继续处理后中水回用；生物处理单元排出的剩余污泥排入磷吸附池，除磷后的污泥进入污泥浓缩池浓缩，浓缩后的污泥制成陶粒，置换人工湿地和磷吸附池中的陶粒填料，置换出来的含磷陶粒作为肥料还田；本发明工艺步骤简单合理，成本低廉，污水处理得当，污泥制成的陶粒吸附磷后可用作农田肥料，能够有效对污泥和磷原位利用。
