sludge cake

This paper introduces the quality and reuse of sludge-dewatering effluent, processes and testing results of making brick with dewatered sludge cake and using sludge as additive fills for cement production, and recovery of aluminium salts from sludge etc.

介绍了水厂排泥水处理后，分离水的水质和回用、泥饼制砖和污泥用作水泥掺合料的方法和试验结果，以及铝盐回收的工艺。

The practical operation shows that the treated water can flow back with uniform rate to the raw water distributing well and sludge cake with water content of 80% has been obtained after mechanical dewatering.

工程运行表明经处理后的生产废水能均匀回流至配水井，经机械脱水后污泥的含水率能达到80%以下。

The formative sludge cake can be used as auxiliary raw material to bake wall material and achieve reutilization of sludge and a benign end disposal.

所形成的污泥滤饼可作为烧制墙体材料的辅助原料，实现了污泥的资源化利用和良性最终处置。
