Abstract

This invention provides a physicochemical treatment system for hazardous waste, comprising: a physicochemical pretreatment unit for classifying and pretreating liquid hazardous waste, the physicochemical pretreatment unit including an inorganic waste liquid treatment line and an organic waste liquid treatment line; an evaporation and concentration unit connected to the outlet of the physicochemical pretreatment unit for evaporating and crystallizing the pretreated wastewater; and a deep treatment unit connected to the outlet of the evaporation and concentration unit for deep purification of the evaporation condensate. This invention systematically integrates "classified physicochemical pretreatment" with "differentiated evaporation and concentration" and "deep membrane biochemical treatment," forming a complete closed-loop treatment chain. The synergistic effect of each unit fully embodies the concept of treating waste with waste and energy conservation and emission reduction. The overall operating cost is low, resulting in good economic and environmental benefits.
