Abstract

The invention belongs to the technical field of coal chemical wastewater treatment, and in particular relates to a purification treatment process of coal chemical wastewater. The process includes thefollowing steps: introducing the wastewater into a wastewater treatment device for pretreatment, precipitation and removal of oil, suspended matters, etc.; carrying out adsorption on the treated wastewater by a resin adsorption method; treating the obtained wastewater by an air stripping tower; and treating the wastewater treated by an air stripping tower in a biological aerobic treatment mode tofurther remove COD and NH3-N in water, so as to complete wastewater treatment. The purification treatment process can efficiently treat coal chemical wastewater, has high working efficiency and savesenergy.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry wastewater treatment, in particular to a coal chemical industry wastewater purification process. Background technique [0002] Coal chemical wastewater refers to the wastewater generated during the pretreatment and treatment of coal processing, mainly including gas-making wastewater, purification and washing wastewater, and wastewater generated from other coal products. It is one of the current difficult-to-treat industrial wastewater. The coal chemical industry has many and complex production processes and consumes a lot of water. Moreover, the composition of wastewater is extremely complex, and the organic pollutants contained include phenols, polycyclic aromatic compounds, and heterocyclic compounds containing nitrogen, oxygen, and sulfur, etc. It is a typical industrial wastewater containing refractory organic compounds. The easily degradable organic substances in wastewater ar...
