山西省高速公路服务区污水处理工艺适用性研究

Research on Applicability of Sewage Treatment Process in Shanxi's Expressway Service Areas

通过对山西省高速公路服务区污水性质及处理工艺进行详细调查,发现山西高速服务区污水产生量随着季节、气候、车流量等变化具有较大的波动性;污水进水水质具有有机污染物浓度高、低C/N的特点。同时对山西省高速公路污水处理工艺对比分析表明A2/O+MBBR工艺的污水处理设备出水水质能稳定达标,满足回用水标准,同时具有技术成熟、稳定性好、建设费用较低、运行成本较低、易运维、适用性强的特点,可以满足环保防治要求。

Through the detailed investigation of the characteristics and treatment technology of sewage in Shanxi's expressway service area,it is found that the sewage production fluctuates greatly with the change of season,climate,and traffic flow.The influent quality has the characteristics of a high concentration of organic pollutants and low C/N.The comparative analysis of expressway sewage treatment technology in Shanxi Province showed that the effluent quality with the A2/O+MBBR sewage treatment equipment could meet the standard of reuse water,with mature technology,good stability,low construction cost,low operation cost,easy operation and maintenance,and strong applicability,which can meet the requirements of environmental protection prevention and control.
