Solid-liquid separation device and separation method for domestic sewage treatment

Abstract

The invention discloses a solid-liquid separation device and method for domestic sewage treatment, and relates to the field of sewage treatment.The solid-liquid separation device comprises a separation box, a screening mechanism is arranged in the separation box, a drying mechanism is arranged on one side of the separation box, and a filtering mechanism is arranged on the other side of the separation box; and the screening mechanism comprises an L-shaped plate, a coarse filter plate, a fixing shaft, a fixing plate, a spring, a fine filter plate, a second motor, a U-shaped frame, a threaded rod and a T-shaped connecting block, a first notch is formed in one side of the separation box, and the two ends of the fixing shaft are fixedly connected with the inner wall of the first notch. According to the device, solids carried in liquid can be separated out to the maximum extent, so that the situation that the solids remain in the subsequent liquid in use is avoided, the purity of the liquid is improved through rough filtration and fine filtration, later secondary utilization is facilitated, the separation effect of the device is improved, meanwhile, the separation efficiency of the device is improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a solid-liquid separation device and a separation method for domestic sewage treatment. Background technique [0002] Domestic sewage is the waste water discharged from the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. Therefore, people have produced a lot of environmental protection and environmental improvement. device, of which the solid-liquid separation device for domestic sewage treatment is one of them. [0003] When the existing devices are used, most of them use a filter plate to filter them. This method has poor filtering effect, so that the small solid impurities contained in the inside cannot be removed, so when it is used for the second time, it needs to be filtered again. , wastes time and resources, and the surface of...

AI Technical Summary

Problems solved by technology

[0003] When the existing devices are used, most of them are filtered with a filter plate. The filtering effect of this method is not good, so that the small solid impurities contained in the device cannot be removed, so it needs to be filtered again when it is used for the second time. , consumes time and resources, and the surface of the solids removed from the liquid is attached with sewage. If it is not treated for a long time, it will breed bacteria, produce peculiar smell, pollute the surrounding environment, and be harmful to the human body at the same time. And the separation is complete The liquid cannot be filtered in a timely manner, and it is prone to stink in the water body and a variety of harmful bacteria if it is placed for a long time, which will pollute the environment and be inconvenient for later treatment.
