摘要
针对工业污水含特征污染物、可生化性较差,处理过程存在噪声、臭气等特点,以广东某工业园区地下式工业污水处理厂设计为例,介绍了全地埋式工业污水处理厂的进水水质特征与废水处理工艺和主要设计参数.工业污水经预处理+水解酸化+A2O+高效沉淀+臭氧+BAF工艺处理后,确保出水能稳定达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准.同时污水处理厂采用多种通风除臭措施,保障了操作人员的舒适度.地下式工业污水处理厂的设计不仅可以满足工业废水处理需求,而且也可以缓解用地紧张的压力,减少水厂运行过程中产生的环境风险.
Abstract
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.
