温州北山河黑臭河水治理工程

Treatment Project for Heavy Polluted Water of Beishan River in Wenzhou

针对温州北山河黑臭河水COD高达1550mg/L的现状,采用厌氧生物膜床结合水生植物带工艺进行治理。结果表明,该综合治理工艺对COD、N,N-二甲基甲酰胺(DMF)、NH3-N的去除率分别达85%、99%、54.1%以上,治理后不但黑臭完全消除,而且河水具有一定的自净能力。该工艺具有处理效果稳定、造价低、操作方便和维护费用低等优点。

The anaerobic biofilm bed coupled with aquatic plant zones was used to treat the malodorous black water of Beishan River with COD concentration of 1 550 mg/L in Wenzhou. The results show that the removal rates of COD, N, N-dimethylformamide （DMF） and NH3 - N are above 85% , 99% and 54.1% respectively. The colour and odor of the water are completely removed, and the water has a self-purification ability. The process has advantages such as stable treatment effect, low capital and maintenance cost and convenient operation.
