Abstract:Coking wastewater is a typical industrial organic/hard-biodegradable wastewater with complicated components and large discharge amount. This paper introduces the quality and quantity of eoking wastewater, the constituents of pollutants, the hiodegradation characteristics of organic compounds and the selection of treatment methods. The technical characteristics of A/O, A^2/O, A/O2 and O/A/O which have denitrogenation ability were analysed. The biological fluidized bed reactor is effective for the removal of COD and nitrogen. DO, temperature, pH value, nutrition, SRT and toxic/harmful matter which affecting the process of pollutants control were discussed; several projects and processes were compared from the technical aspects and economic differences. The control strategies of some sensitive indicators were introduced. It was pointed out that the technological innovation and policy-related compensation benefit the solving of environmental problem.
Keywords:eoking wastewater  pollution characteristics  pollution control  control strategies  engineering technology
