农村水网地区河浜生态拦截示范工程设计

水网地区农村河浜生态拦截工程将河浜作为净化载体,采用河浜原位增氧-动态生态组合工艺(ODBP),既增进了河浜的消纳净化能力,减轻了水体的富营养化程度,又改善了村镇水体的污染状况。采用该技术处理江苏常州武进区某农村生活污水和农业生态排水的示范工程表明,出水各项指标(氨氮、总氮、总磷、悬浮物、化学需氧量)均满足《城镇污水处理厂污染物排放标准(GB18918—2002)》一级A标准。这种生态法河浜治理模式不仅效果好、投资小、运行费用低,而且不占用土地,不需要专人进行管护,实现了村镇生活污水和农业面源污水的原位处理,具有一定的应用示范及推广意义。

The Demonstration Project of River Ecological Interception in Rural Water Network Region

Rural river ecological interception project in water network region takes river as purification carrier, and uses river in situ aeration-dy-namic ecological combination process ( ODBP) .It not only improves the self purification ability of the river and decreases eutrophication degree of water body, but also improves pollution condition of water body in the village.The engineering practice indicated that the concentrations of COD, TN, TP, NH3 -N and SS all could meet Grade-one A discharge standard of the Discharge Standards of Pollutants in Urban Sewage Pro-cessing Plant (GB18918—2002).The model of ecological creek for wastewater treatment has not only good effect, small investment and low op-eration cost, but also the advantage of land saving, and it doesn’t need professional technician to manage, thereby achieving in-situ treatment of domestic sewage and agricultural non-point source wastewater from town, the project has certain application demonstration and popularization sig-nificance.
