针对北京怀柔渤海镇沟域水产养殖中饵料利用率低、氮磷流失严重造成的水体中氮磷含量高、流域水环境恶化等问题，研究并建立一套集“源头净化—过程消减—尾水深度处理”的养殖水体综合养护示范工程。该工程通过生物絮凝沉淀池＋纳米功能陶粒生物菌种处理池以及表面流人工湿地＋复合生态多功能净化塘，分别对养殖用水和养殖废水进行处理。结果显示，养殖用水除总氮（ TN）以外均稳定达到地表Ⅲ类水标准；养殖废水则除TN外可稳定达到地表Ⅴ类水标准；通过种植植物等使水体周边生态环境得到了较好的恢复。处理后TN不达标可能是由于有机物浓度低和DO浓度较高等限制了反硝化作用。

To better solve the existing issues including low feed utilization rate, a serious nitrogen and phosphorus loss from valley aquaculture and serious water environmental deterioration in the Bohai town of Huairou, a maintenance demonstration project for aquaculture waters was studied and established, which included water source purification-reduction in the process-wastewater deep treatment.Demonstration project consists of two parts:the aquaculture water is purified by biological flocculation and sedimentation tank+Nano functional ceramic biological species treatment tank;the aquaculture wastewater is treated through surface flow constructed wetland+complex ecology multifunctional purify pond.The result showed that all the parameters of aquaculture water conformed to the third level ( III ) surface water standard except for TN; and all the parameters of the aquaculture wastewater attained the fifth Level ( V) surface water standard except for TN. The surrounding ecosystem had a good recovery as well through planting water plants, etc.TN was not up to the standard, the reason possibly because the denitrification was restricted due to low concentration of organic matters and high DO concentration.
