Sewage treatment device

Abstract

The invention discloses a sewage treatment device, and belongs to the technical field of sewage treatment. A water inlet is formed in the upper end of one side of a sewage treatment tank, a water outlet is formed in the bottom of the other side of the sewage treatment tank, an end cover is arranged at the top of the sewage treatment tank, and openable cover bodies are installed on the two sides ofthe end cover. The filtering mechanism comprises a driving motor, a shaft rod and a filtering disc; the shaft rod comprises a screw rod end and a polish rod end; the filter disc comprises a base plate and a filter screen disc, the filter screen disc is connected to the screw rod end of the shaft rod, the base plate is connected with the polished rod end of the shaft rod in a penetrating mode, anda centrifugal device is further arranged in the sewage treatment box. According to the sewage filtering device, sewage impurities are filtered in a graded mode, the purpose of sewage stirring and filtering is achieved, the situation that the sewage treatment efficiency of the whole filtering mechanism is affected due to blockage of the filtering net disc can be effectively avoided, the whole filtering mechanism is simple in structure, convenient to operate and convenient to install, and the sewage treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, more specifically, to a sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. Filtration refers to the process of purifying fluid through special devices. There are many ways to filter, and a wide range of material systems are used. Solid-liquid, solid-gas, large particles, and small particles are all common.

Problems solved by technology

[0003] Sewage treatment devices are required for sewage treatment, but most of the existing sewage treatment devices pour sewage directly into the filter device for filtration treatment when treating sewage, and the sewage passes through the filter mechanism from above to below, so that the filtered dirt, Impurities will stay on the surface of the filter net. After a long time, the filter cake effect will be formed to block the filter net, affecting the filtering effect. It is also easy to breed bacteria and microorganisms, and it is inconvenient to clean. The filter mechanism must be taken out, or the filter mechanism must be replaced directly. higher
