Design and Application of Improved A2O-Ozone-BAF Process in Underground Industrial Wastewater Plant
In view of the characteristics of industrial wastewater containing characteristic pollutants,poor biodegradability,noise and odor in the treatment process,taking the design of an underground industrial wastewater treatment plant in an industrial park of Guangdong as an example,the design of a fully buried industrial wastewater treatment plant,which influent quality characteristics,wastewater treatment process and main design parameters is introduced.After pretreatment+enhanced A2O+high efficiency precipitation+ozone+BAF process,the effluent of industrial wastewater treatment plant can be stably meet the first class A criteria of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants(GB 18918-2002).What's more,the wastewater plant adopts a variety of ventilation and deodorization measures to ensure the comfort of operators.The design of underground industrial wastewater plant can not only meet the demand of industrial wastewater treatment,but also relieve the pressure of land shortage and reduce the environmental risk generated during the operation of water plant.
