Sedimentation type sewage treatment device

Abstract

The invention discloses a sedimentation type sewage treatment device, which comprises a pretreatment mechanism and a sedimentation mechanism; the sedimentation mechanism comprises a second filter box,a suction pump is installed on the upper end face of the second filter box, a water inlet of the suction pump is communicated with a water pumping opening, and a biomass film is fixedly installed onthe upper end face of the interior of the second filter box; the lower end face of the biomass film is closed, and the water pumping opening is communicated with the interior of the biomass film. Thesewage is treated by the pretreatment mechanism and the sedimentation mechanism and then can be directly discharged after being subjected to chemical treatment of pollution particles in the sewage, wherein the sewage is treated for multiple times in a two-stage treatment process, so that the occupied area of the sewage treatment device is reduced, the size and the cost of sewage treatment equipment are reduced. The sewage treatment device is more suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a device related to sewage treatment, in particular to a sinking sewage treatment device. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. There are many ways to treat sewage, which can be generally classified into physical methods, chemical methods and biological methods. Usually, the process of sewage treatment is as follows: sewage is treated in sequence by sedimentation tank, advection tank, filter device, concentration tank, mud-water separation device, etc. In this process, various treatments such as physical method, chemical method and biological method will be used. method, multiple treatment methods are combined and used cross-over, but the sedimentation tank used in this traditional process requires a large area to achieve the expected sedimentation effect, and the equipment involved in eac...

Problems solved by technology

Usually, the process of sewage treatment is as follows: sewage is treated in sequence by sedimentation tank, advection tank, filter device, concentration tank, mud-water separation device, etc. In this process, various treatments such as physical method, chemical method and biological method will be used. method, multiple treatment methods are combined and used cross-over, but the sedimentation tank used in this traditional process requires a large area to achieve the expected sedimentation effect, and the equipment involved in each process can only filter the sewage once. Or treatment, so more equipment is needed to treat sewage, so that the investment in sewage treatment equipment is large, and the cost of maintenance and use is also increased accordingly. Due to the above reasons, the use of traditional sewage treatment equipment is limited, and the universality is greatly reduced.
