摘要
针对公路服务区传统人工湿地污水处理技术存在的启动调试滞后、占地面积大、湿地床易堵塞等实际问题,开展了改良人工湿地处理研究,选用废砖块、空心砖和废陶瓷等作为湿地填料,引入湿地模块化设计的理念,采用进水低位双泵控制系统及阶梯增加水力负荷和间歇投配的启动方式,在江西某服务区建设示范工程,处理后出水水质稳定,达到GB/T 18920—2002《城市污水再生利用城市杂用水》中城市绿化用水标准。
According to the wastewater characteristics of highway service areas,the traditional constructed wetland was modified in order to save construction investment,prevent blockage and concentrate area. The new technology based on the theory of modular design,started up by using the mixed packing medium with bricks and waste ceram,stepwise increasing of hydraulic loading and taking operation of intermittent filling. The application of wastewater treatment project in the service area in Jiangxi province showed that the effluent of wastewater project could reached the requirements of the standard of urban greenbelt water use of the'municipal wastewater reuse( GB /T 18920—2002) '.
