Chemical plant sewage pool decontamination apparatus

Abstract

The present invention provides a chemical plant sewage pool decontamination apparatus, which comprises a sewage pool, wherein the bottom portion of the sewage pool is provided with a water discharging port, the top portion of the sewage pool is provided with a sewage inlet, a conveying belt is arranged inside the sewage pool and is connected to a rotation shaft, the rotation shaft is fixed on the inner wall of the sewage pool, the conveying belt is provided with a filtration hole, a water storage box is arranged just below the conveying belt, a garbage storage zone is arranged between the water storage box and the sewage pool, and a garbage discharging port is arranged on one side of the lower portion of the sewage pool. According to the present invention, with the chemical plant sewage pool decontamination apparatus, the decontamination is convenient, the problem that the residue cleaning requires the complete draining of the sewage in the pool is avoided, the condition that the solid garbage and the sewage are subjected to long-term deposition so as to cause the malodor can be prevented, and the environment pollution can be avoided.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment in chemical plants, in particular to a decontamination device for sewage pools in chemical plants. Background technique [0002] Many of the existing wastewater from chemical plants are rich in nitrogen, phosphorus, inorganic salts and other substances. The existing treatment method is to neutralize them by adding chemicals. Therefore, sometimes chemical plants violate laws and regulations without permission. Treated wastewater, which will cause eutrophication after entering public water sources, and at the same time, there will be solid waste in the sewage pool for a long time. The slag removal device of the sewage pool in the prior art generally adopts to drain the sewage in the pool first, and then use a pump or manually to remove the solid waste at the bottom of the sewage pool, or simply connect a pipeline valve at the bottom of the sewage pool for discharge. Adopting such cessp...

AI Technical Summary

Problems solved by technology

Of course, the slag removal technology of such a sewage pool can be used normally, but the method of draining the sewage in the pool first and then cleaning the slag is inefficient

In order to continuously remove slag, people simply connect the pipe valve at the bottom of the sewage tank to discharge, but the air bubbles are easy to block in the pipe when the pipe diameter is small, affecting the smoothness of the discharge. The use effect is not ideal enough. After the foul smell is caused by the deposition of garbage in the sewage pool, it will affect people's normal life and pollute the environment.
