Abstract

A sewage treatment system, including a sewage tank, a degradation tank, an absorption tower, a recovery tank and a crystallization unit, the technical points are: the sewage tank is connected to the bottom air inlet of the absorption tower I, and the top exhaust end of the absorption tower I is connected to the The bottom air inlet of absorption tower II is connected, the top exhaust end of absorption tower II is connected with the bottom air inlet of absorption tower III, the top exhaust end of absorption tower III is connected with the atmosphere, absorption tower I and absorption tower The bottom discharge end of II is respectively connected with the recovery tank, the top exhaust end of the absorption tower I is connected with the bottom air inlet of the recovery tank, and the top exhaust end of the absorption tower II is connected with the top air inlet of the recovery tank , The liquid discharge end at the bottom of the recovery pool passes through the crystallization unit, the pump body II and the liquid inlet end at the top of the recovery pool to form a crystallization cycle. It has the advantages of simple and compact structure, low construction cost, convenient use, high processing efficiency and good processing effect.

Description

technical field [0001] The invention relates to treatment equipment for industrial waste discharge, in particular to a sewage treatment system, which is mainly suitable for the treatment of toxic, harmful and odorous volatile organic compounds (VOCs). By recycling and treating the foul-smelling gases collected after the sewage pool is sealed, such as ammonia, hydrogen sulfide, and other VOCs, they will finally be discharged up to the standard. Background technique [0002] The treatment of VOCs is an important part of environmental protection work. In the existing methods, the organic hydrocarbons in them are often only decomposed by biodegradation, and other volatile gases are not effectively utilized, resulting in unnecessary waste. Contents of the invention [0003] The object of the present invention is to provide a sewage treatment system that fundamentally solves the above problems, and has the advantages of simple and compact structure, low construction cost, conven...
