These pollutants have complex chemical properties and strong biological inhibition, and belong to typical high-concentration and difficult-to-biodegrade industrial wastewater.

[0003] The coal chemical wastewater treatment process usually includes three stages of pretreatment, biochemical treatment and advanced treatment.
