This paper describes the reuse water of wastewater treatment reuse water treatment station and zero discharge treatment station in a coal chemical project.As the cooling tower of circulating water field,the temperature is too high in summer,which affects the operation of circulating water system.As the raw water of desalination station,the desalination water reverse osmosis cleaning is frequent,the quality of mixed bed water is decreased,the resin regeneration cycle is shortened,and the water rate is increased.Through analysis and research,it is proposed that part of the reuse water can be used as the production water of gasification and other production devices,and the other reuse water can be used through classification and optimization,ladder reuse to the cooling tower and production water.The results show that the proposed reuse engineering scheme of coal chemical reuse water can realize the rational utilization of water resources.
