Description

Technical Field

[0001] The utility model relates to the field of sewage treatment tanks, in particular to a sewage treatment tank for sewage treatment equipment. Background Art

[0002] A sewage treatment tank is a device used to treat wastewater. Its core function is to remove suspended solids, organic matter, and microorganisms from the water through physical, chemical, or biological processes, thereby purifying the water. There are many types of sewage treatment tanks, each with its own specific application scenarios and technical characteristics.

[0003] Since different treatment agents need to be added to the water in sequence during sewage treatment, if one tank is used, it is necessary to wait for the first treatment agent to fully react before adding the second treatment agent, which increases the treatment cycle; if two tanks are used, although two chemical reactions can be completed at the same time to achieve continuous operation, the tanks increase the floor space, are greatly restricted by surrounding environmental factors, and the cost is also high.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the sewage treatment equipment uses a sewage treatment tank, which is provided with three vertically distributed areas in the tank body. When the movable partition is moved up to close the first feeding area, the first treatment agent can be poured in to make the sewage in the first feeding area react; then when the movable partition is moved down to close the second feeding area, the first feeding area is in an open state, at this time the sewage in the first feeding area enters the second feeding area from the water permeable hole, and then the second treatment agent is poured in to react; then the movable partition is moved up again to close the first feeding area and open the second feeding area, and the sewage in the second feeding area can enter the drainage area through the water permeable hole and then be discharged from the drainage pipe. At this time, the next wave of sewage to be treated enters the first feeding area, and the above process is repeated. That is, the discharge of the first wave of sewage and the filling of the second wave of sewage with the first treatment agent can be carried out simultaneously, thereby realizing continuous feeding reaction and effectively improving treatment efficiency; and only one tank body is required to achieve this, saving cost and floor space.
