一体化生态浮岛对富营养化和黑臭水体修复的应用研究

Application of Integrated Ecological Floating Island for Remediation of Eutrophic and Black Odorous Water

由于大量的工业废水和生活污水直接排入河涌,水体富营养化、黑臭等问题日趋严重。针对此问题,本研究设计了一种高效处理水体污染,解决水体黑臭问题的一体化生态浮岛装置。通过该装置对校园富营养化湖水处理以及黑臭水体处理试验表明,对富营养化水体进行处理后,COD、NH^(+)_(4)-N和TP去除率分别为:24.8%、83.9%和31.5%,DO浓度提高了46.3%;对黑臭水体进行处理后,COD、NH^(+)_(4)-N和TP去除率分别为:23.0%、83.1%和93.1%,DO浓度提高了95.9%,出水达到地表水Ⅳ类标准(GB3838-2002)。

A large amount of industrial waste water and domestic sewage are directly discharged into the river,increasing serious problems such as eutrophication,black and odor.In response to this problem,an integrated ecological floating island device that efficiently treated water pollution and solved the problem of water body black and odor was designed.Experiments on the treatment of eutrophic lake water and black and odorous water bodies on campus by this device showed that after treatment of eutrophic water bodies,the removal rates of COD,NH^(+)_(4)-N and TP were 24.8%,83.9%and 31.5%,DO concentration increased by 46.3%.After treating the black and odorous water,the removal rates of COD,NH^(+)_(4)-N and TP were 23.0%,83.1%and 93.1%respectively,DO concentration increased by 95.9%and the effluent reached the surface water level IV standard(GB3838-2002).
