Background technique

With the rapid development of social economy, the amount of water and sewage discharged by the society is also increasing day by day, and the shortage of water resources and the pollution are becoming more and more serious. Municipal water supply treatment, industrial water supply treatment, municipal sewage advanced treatment, industrial sewage advanced treatment and reclaimed water reuse are becoming more and more popular. At the same time, land resources are becoming less and less, especially in towns and factories, where land is particularly scarce. There are basically two types of water treatment and purification devices today: the first is the traditional split structure, that is, flocculation, sedimentation, and filtration are each a structure. The management is cumbersome; the second is to simply combine the traditional split structures together. The water treatment facilities in this case still occupy a large area and require high investment, which is not suitable for large water treatment.
