A Coal Chemical Wastewater Treatment System

Abstract

The invention belongs to the technical field of waste water treatment, and specifically relates to a coal chemical waste water treatment system, which includes a treatment box and a medicine box; it also includes a No. 1 stirring unit, a No. 2 stirring unit, and a drug nozzle; The flocculant is dissolved into the waste water at low speed; the No. 2 stirring unit is used for dissolving the flocculant into the waste water at high speed; the medicine nozzle is used for spraying the flocculant into the treatment tank. In the low-speed stirring, the No. 1 stirring unit and the No. 2 stirring unit are complementary to stir, on the one hand, the collision area between the flocculant and the impurities in the waste water is increased, thereby accelerating the dissolution efficiency of the flocculant and waste water, thereby improving the purification of waste water Efficiency; on the other hand, the flocculant is sprayed into the treatment tank reasonably according to the needs, so that the flocculant and the wastewater are dissolved, avoiding the waste of the flocculant, thereby improving the utilization rate of resources.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a coal chemical wastewater treatment system. Background technique [0002] Wastewater refers to the general term for water discharged from residents' activities and runoff rainwater. It includes other useless water such as domestic sewage, industrial wastewater, and primary rainwater flowing into drainage pipes and channels, and generally refers to water that is not used or has no value in use. The concentration of wastewater pollutants is high, and the organic components are complex, mainly including phenolic compounds, polycyclic aromatic compounds, heterocyclic compounds containing nitrogen, oxygen, sulfur, and fatty compounds, which are difficult to biodegrade. If the coal-to-gas wastewater is not properly treated and discharged beyond the standard, it will cause serious pollution to the ecological environment. Therefore, how to effectively treat the coal-to-gas...

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art and aim at the problem of insufficient stirring in the original scheme, a coal chemical wastewater treatment system proposed by the present invention, by setting No. 1 stirring unit and No. 2 stirring unit, in low-speed stirring, No. 1 stirring unit Complementary stirring between the unit and the No. 2 stirring unit. On the one hand, it increases the collision area between the flocculant and the impurities in the wastewater, thereby accelerating the dissolution efficiency of the flocculant and the wastewater, thereby improving the purification efficiency of the wastewater; on the other hand, reasonable The flocculant is sprayed into the treatment tank to dissolve the flocculant and wastewater, avoiding the waste of flocculant, thereby improving the utilization rate of resources
