Urban domestic sewage treatment device

Abstract

The invention relates to the technical field of sewage treatment devices, and discloses an urban domestic sewage treatment device. The device comprises a box body, a water inlet is fixedly connected to the outside of the box body, a flashboard is movably connected to the inside of the water inlet, a steel pipe is fixedly connected to the inside of the box body, a filter box is fixedly connected to the outside of the steel pipe, a filtering plate is fixedly connected to the exterior of the filtering box, a feeding opening is formed in the exterior of the box body, a storage groove is formed in the box body, a driving motor is fixedly connected to the interior of the storage groove, a supporting shell is fixedly connected to the interior of the box body, a bevel gear set is movably connected to the interior of the supporting shell, and a transmission shaft is movably connected to the interior of the supporting shell. A stirring impeller on a rotating rod rotates, and in the rotating process of the stirring impeller, the reaction between the sewage and a sewage treatment agent is accelerated, so that the chemical reaction is more sufficient, and the effects of quickly purifying and disinfecting and improving the working efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban domestic sewage treatment device. Background technique [0002] Urban sewage refers to the general term for the sewage discharged into the urban sewage system. Urban sewage mainly includes domestic sewage and industrial sewage. The urban sewage treatment process generally determines the degree of sewage treatment according to the utilization or discharge of urban sewage and the natural purification capacity of the water body. And the corresponding treatment process, and according to the degree of treatment, it is divided into primary, secondary and tertiary treatment processes. At present, the primary treatment uses physical methods, such as screening, sedimentation, etc. to remove insoluble suspended solids and floating substances in sewage. [0003] A large amount of sewage will be produced in daily urban work. If the sewage is not treated in time, it will cau...
