Sewage treatment device for adjusting filtering efficiency based on water pressure

Abstract

The invention discloses a sewage treatment device for adjusting the filtering efficiency based on water pressure, wherein the sewage treatment device comprises a treatment cylinder, the top of the treatment cylinder communicates with a suction pipe, the inner wall of the treatment cylinder is fixedly connected with a hollow fiber partition plate, and the hollow fiber partition plate divides an inner cavity of the treatment cylinder into two stages of cavities; and a pressure filter plate is fixedly mounted on the inner walls of the two stages of cavities, and needle holes are formed in the pressure filter plate. According to the sewage treatment device for adjusting the filtering efficiency based on the water pressure, due to the fact that two ends of a transmission shaft are made of metamaterials and have the characteristics of being pressed and twisted, the transmission shaft can be driven to rotate, the meshing effect of a gear and a rack plate is achieved, and the baffle is moved away; and under different water pressure, the distortion amplitude of the transmission shaft is different, when the water pressure in the suction pipe is influenced by external conditions and becomes small, the baffle cannot be completely moved away due to incomplete torsion of the transmission shaft, the number of rows of exposed needle holes is reduced, and the filtering rate is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for adjusting filtration efficiency based on water pressure. Background technique [0002] Sewage treatment refers to the purification process that treats sewage to meet the requirements of a certain water body or can be reused. People's lives and various industrial productions in cities will produce a large amount of sewage. If these sewage are not treated and discharged directly, it will be It causes serious pollution to the environment. At present, the commonly used sewage treatment methods are mostly physical sedimentation method and chemical sedimentation method. This kind of treatment method has some defects in the process of sewage treatment. [0003] After the traditional hollow fiber membrane sewage treatment equipment has been filtered for a period of time, the pores in the filter plate will be covered by grease, sludge and other subst...

[0002] Sewage treatment refers to the purification process that treats sewage to meet the requirements of a certain water body or can be reused. People's lives and various industrial productions in cities will produce a large amount of sewage. If these sewage are not treated and discharged directly, it will be It causes serious pollution to the environment. The commonly used sewage treatment methods are mostly physical sedimentation method and chemical sedimentation method. This kind of treatment method has some defects in the process of sewage treatment.

[0003] After the traditional hollow fiber membrane sewage treatment equipment has been filtered for a period of time, the pores in the filter plate will be covered by grease, sludge and other substances in the sewage, resulting in clogging of the membrane pores, which not only affects the sewage treatment efficiency, but also causes damage to the treatment equipment
