Wastewater treatment system

Abstract

A wastewater treatment system comprises a wastewater tank, a degradation tank, absorption columns, a recycling tank and a crystallization unit and is technically characterized in that the wastewater tank is connected with the bottom intake end of the absorption column I, the top exhaust end of the absorption column I is communicated with the bottom intake end of the absorption column II, the top exhaust end of the absorption column II is communicated with the bottom intake end of the absorption column III, the top exhaust end of the absorption column III is communicated with the air, the bottom drain end of the absorption column I and the bottom drain end of the absorption column II are communicated with the recycling tank, the top exhaust end of the absorption column I is communicated with the bottom intake end of the recycling tank, the topo exhaust end of the absorption column II is communicated with the top intake end of the recycling tank, and the bottom drain end of the recyclingtank forms a crystallization cycle with the top inflow end of the recycling tank through the crystallization unit and pump block II. The wastewater treatment system has the advantages of simple compact structure, low setup cost, good convenience of use, high treatment efficiency, good treatment effect and the like.

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...
