Technical Field

The utility model relates to the technical field of water treatment, in particular to a suspended sludge method treatment device.

Background

The principle of the water treatment by the suspension sludge method is to treat raw water by using a suspension sludge layer formed by the energy of continuous rising water flow. Raw water and a coagulation agent enter from the bottom of the tank, the formed alum flowers are suspended by upward water flow and are deposited into a stable suspension layer, and the alum flowers in the suspension layer have a contact coagulation effect and treat the raw water. In order to control the suspended mud layer at a certain height, the residual mud is continuously and automatically discharged into a mud concentration chamber, and discharged out of the pond in the later stage of compaction.
