Sewage treatment device

Abstract

The invention relates to a sewage treatment device. The sewage treatment device comprises a treatment cavity, wherein a rotary motor is arranged on the outer side of the treatment cavity and is connected with a cutting disc through a rotation shaft, the cutting disc is longitudinally arranged in the treatment cavity, the two ends of the cutting disc attach to the inner wall of the treatment cavity, and cutting edges are distributed in the cutting disc. The treatment cavity on the two sides of the cutting disc serve as a water inlet cavity and a water outlet cavity, a water inlet pipe is arranged on the side wall of the water inlet cavity, a water outlet pipe is arranged on the side wall of the water outlet cavity, the water inlet pipe and the water outlet pipe are oppositely arranged, and the disc diameter of the cutting disc is greater than the pipe diameters of the water inlet pipe and the water outlet pipe. A storage tank is arranged at the lower portion of the treatment cavity, and the treatment cavity is in spatial communication with the storage tank. The sewage treatment device utilizes power brought by the water pressure difference between the water inlet pipe and the water outlet pipe and the effects of the cutting edges formed in the cutting disc and the rotary force of the cutting disc to enable sewage to be directly layered in a sewage pipe in the sewage cutting and shattering process, directly cuts and shatters easily-treated sewage, improves the sewage treatment efficiency, ensures the sewage treatment effect and does not easily cause sewage blockage.

Description

technical field [0001] The invention belongs to the technical field of the combination of a filter circuit or a filter and other separation devices, and particularly relates to a method for rationally stratifying the sewage during the initial discharge of sewage, and using the power brought by the kinetic energy of the sewage to cooperate with the cutting mechanism to treat the sewage Larger ones can handle sewage to ensure the efficiency and effect of sewage treatment, and sewage treatment devices that are not easy to cause sewage clogging. 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. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. More and more into the daily life of ordinary people. [0003] The existing sewage ...

Problems solved by technology

[0005] The technical problem solved by the present invention is that in the prior art, the primary treatment of sewage is generally completed through the cooperation of grids, grit chambers and sedimentation tanks. In fact, sewage passes through a large number of pipelines. If the sewage cannot be transported Reasonable layering and cutting of the material will miss the best and most direct opportunity to crush the sewage in the pipeline flow stage, resulting in low primary treatment efficiency, secondary treatment cannot be carried out normally, and subsequent treatment is easy The problem of irreversible damage caused by the hardware facilities in the process, and then provides a sewage treatment device with an optimized structure
