【摘要】 在上海市崇明县森林旅游园区建成郊区污水处理示范工程。采用生物强化絮凝+人工湿地组合工艺,充分发挥了物化与生态工艺的互补优势,其中人工湿地占地近6000m2;通过强化预处理对SS和P的去除削减污染负荷,使湿地水力负荷提高到0.6m3/(m2·d);通过优化湿地浸润线使NH3-N、TN同时达标。人工湿地利用林间空地布局,采用自主开发的模拟软件设计,根据实际情况合理选择工艺并优化运行,实现污水污泥同步资源化利用。工程已运行一年,技术经济指标达到了863示范工程要求,出水水质可达GB18918—2002一级A标准。更多还原

【Abstract】 In Chongming Island near Shanghai, a rural domestic wastewater treatment demonstration project has been built up. The scheme of biologically enhanced flocculation combined with vertical downward flow wetland(6 000 m~2 area)was developed, which sufficiently exploit the particular advantages of physicochemical and ecological technologies. SS and P were removed in pretreatment, and which also greatly reduce pollutant load on wetland, then increasing the HLR of wetland to 0.6 m~3/(m~2·d). By saturation line optimization, NH_ 3 -N and TN both reached the Class I-A of the national standard GB 18918—2002 in this country. Since utilization of the space between trees, process design by the self-developed software, rational selection of technological combination and optimized operation according to reality water and solid reuse, the project has strikingly characteristics; moreover, technical and economic target of the 863 demonstration project were successfully achieved, it shows brightly environmental, ecological and social benefit.更多还原
