Pretreatment type domestic sewage treatment device

Abstract

The invention discloses a pretreatment type domestic sewage treatment device. The device comprises a machine body, whrein the inner wall of the machine body is sequentially connected with a medicine feeding assembly, a stirring assembly and a filter screen from top to bottom, the medicine feeding assembly comprises a medicine feeding pipe, the medicine feeding pipe is slidably connected with the inner wall of the machine body, a plurality of spray holes are uniformly formed in the medicine feeding pipe, weight sensing devices are connected to the two ends of the filter screen, and the medicine feeding assembly, the stirring assembly and the weight sensing devices are electrically connected with a controller. According to the pretreatment type domestic sewage treatment device provided by the invention, the weight of lumps on the filter screen is monitored in real time through the weight sensing devices, the adding amount of a purifying agent is controlled, the purifying agent is uniformly sprayed into sewage through horizontal circulating movement of the chemical feeding pipe, and stirring is quickly performed, so that the input amount of the purifying agent can be accurately controlled; the device effectively adapts to different sewage states, so that the purifying agent is in full contact reaction with the sewage, and the sewage purifying effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pretreatment type domestic sewage treatment device. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. In recent years, with the acceleration of urbanization, a large amount of sewage will be produced in the process of life and production. The sewage is often mixed with massive pollutants. The direct discharge of sewage not only pollutes water sources and soil, but also passes through the food chain. In order to make the sewage meet the discharge standard, it is necessary to treat the sewage. In the prior art, the method of adding purifiers is often used to purify sewage. However, due to the uncertain content of massive pollutants in sewage, it is impossible to determine the amount of purifiers used according to the situation of massive pollut...
