温州上京浃河黑臭河水治理工程

Treatment Project for the Black-odorous Water of Shangjingjia River in Wenzhou

温州上京浃河受生活污水和餐饮废水污染,流动性差,黑臭严重;采用活水造流、曝气增氧、仿生水草及水生植物等综合措施进行2年的治理,结果表明,污染严重的上京浃河水CODCr、氨氮、总磷及溶解氧等主要水质指标均达《地表水环境质量标准》(GB3838-2002)Ⅴ类水的水平,且生物相较为丰富。

The Shangjingjia River in Wenzhou City has been heavily polluted and the water became black and odor due to the discharge of domestic sewage and restaurant wastewater nearby,and weak mobility.A series of techologies of flowing water production,aeration,bionic aquatic filler and aquatic plants were used to treat the water.The twoyear operation results showed that the chemical oxygen demand,ammonium nitrogen,total phosphorus and dissolved oxygen of the river water satisfy the Class V standard for surface water environmental quality(GB3838-2002).Besides,the biological phase was abundant.
