印染园区中水回用提标改造实例OA

Based on the concepts of"clear water and wastewater diversion"and"salt content diversion",a com-bined process of physicochemical+biochemical+advanced oxidation was adopted for preliminary wastewater treatment in a medium-scale textile dyeing park.Subsequently,activated carbon adsorption and an MCR(membrane chemical reactor)+RO(reverse osmosis)dual-membrane process were applied for reclaimed water reuse.The actual operation results demon-strated that the park's comprehensive reclaimed water reuse rate increased from 53%to 68%,while the discharged efflu-ent consistently met discharge standards and complied with the requirements of the upgrading initiative for stricter environ-mental regulations.
