Sewage treatment device beneficial to environmental protection

Abstract

The invention discloses a sewage treatment device beneficial to environmental protection. The sewage treatment device comprises a tank body, wherein an opening of the tank body is a beveled opening, atank cover matched with the tank body sleeves above the tank body, the cross section of the tank cover is of a parallelogram, a water inlet pipe is fixed to the side face of the tank cover in a run-through manner, the water inlet pipe and the tank cover are fixed through welding, a tubular body is fixed to the top surface of the internal wall of the tank cover, an opening of the tubular body faces to a pipe orifice of the water inlet pipe, a plurality of through holes A are uniformly formed in the surface of the tubular body, and a conveying screw rod matched with the tubular body is fit withthe interior of the tubular body. According to the sewage treatment device, the conveying screw rod is used for conveying out lumpy dirt from sewage, thus, a filtering meshed plate is prevented fromblockage, the speed of water intake and filtering is increased, and the work efficiency is high; and brush hair of a sleeve with the brush hair brush the bottom surface of the filtering meshed plate under the drive of a motor A, and thus, mud is further effectively prevented from blocking up meshes of the filtering meshed plate. The sewage treatment device is small in size and can meet the requirements on multi-place moving sewage treatment.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sewage treatment device beneficial to environmental protection. Background technique [0002] With the progress and development of social science, people's awareness of safety, environmental protection and water quality requirements are constantly improving. While industrial development has brought convenience to people's lives, it also produces a variety of harsh domestic waste, of which domestic sewage is one. Generally, domestic sewage contains sludge and various details. If it is directly discharged into the natural environment, it will cause pollution to the natural environment. Therefore, the sewage must be treated before it can be discharged. The domestic sewage in the city is generally concentrated in the sewage treatment plant for centralized treatment, and transport vehicles are used for transportation, which is very inconvenient, and some sewage can be treate...

AI Technical Summary

Problems solved by technology

The domestic sewage in the city is generally concentrated in the sewage treatment plant for centralized treatment, which will be transported by transport vehicles, which is very inconvenient, and some sewage can be treated by simple physical methods

When the existing sewage treatment device treats sewage, large pieces of dirt tend to press the filter plate, affecting the filtration of sewage, and the sludge in the sewage is also easy to block the filter holes of the filter plate, seriously affecting the filtration efficiency

Moreover, the filter plate is installed inside the device, which is not easy to disassemble and clean

The existing sewage treatment device is used to stir the sewage and the mixing device of the chemical agent, the mixing effect is poor, the dirt is easy to accumulate on the filter membrane, it is not easy to replace, and the service life is low

Moreover, the ultraviolet sterilizing modules used in the existing sewage treatment devices are mostly placed in the drainage pipes, which not only reduces the drainage speed, but also has a general bactericidal effect, low overall use efficiency, and slow sewage treatment speed, which is very impractical and unreliable
