[0002] Coke, as a representative product of the traditional coal chemical industry, plays an important role in the steel industry. However, as a highly polluting and water-intensive industry, each stage of coal coking generates a large amount of wastewater. For the comprehensive wastewater discharged by coking enterprises, the following treatments are applied sequentially: ozone oxidation, gravity oil removal, air flotation oil removal, pre-aeration, primary A / A / O biological denitrification, secondary A / O biological denitrification, mixed flocculation, catalytic micro-electrolysis, flocculation sedimentation, ultrafiltration, weak acid ion exchange bed, salt separation nanofiltration, reverse osmosis, concentrate nanofiltration, photocatalytic treatment, and steam compression evaporation. This allows for the recovery of comprehensive coking wastewater while simultaneously evaporating and crystallizing salts to meet industrial-grade salt standards, achieving the goal of zero discharge of comprehensive coking wastewater.
