Abstract: This paper analyzed the process,main structures and design parameters of the industrial wastewater treatment in a coal plant in Xinjiang. The treatment effect and wastewater effluent were evaluated. The average removal rates of COD,NH₃-N,phenols were 96.1%,99.3%,and 99.9%,respectively,and their average concentrations in the effluent was 59,0.84,and 0.28 mg/L. The average removal rate of TN after treatment of phenol-ammonia recovery wastewater was 82.5%,and its average concentration was 31 mg/L. The indexes except for ion pollutants were superior to the Standards in Reusing Wastewater Quality Standard for Industrial Circulating Cooling Water(HG/T 3923-2007).

Key words: Lurgi gasifier, coal chemical industrial wastewater, operational efficiency
