摘要
以黄河下游地区引黄水库为水源,进行了炭砂深床滤池对有机物去除特性研究。结果表明,深床滤池对浊度去除率在90%以上,对CODMn、UV254和NH3-N的去除率分别为37.6%、33.7%和27.9%,炭砂深床滤池对相对分子质量小于103的有机物去除量最多,约占总量的54%,其主要是活性炭表面微生物起作用,生物总量(以P计)最高为22.3 nmol/g。对三卤甲烷前驱物(THMFP)有较好的去除效果,可以将THMFP的质量浓度由85μg/L降到45μg/L以下,去除率达47%。
The characteristics of organic matters removal were studied with GAC-Sand dual media deep filter for the Yellow Riverreservoir water. The results showed that GAC-Sand filter had effective removal on organic matters and the removal rate of turbidity, CODMn, UV254 and NH3-N which were90%, 37.6%, 33.7% and 27.9% respectively. Organic matters of relative molecular mass(Mm) less than 1 000 was removed about 54% of the total, and GAC surface microbes plays a major role, the highest biomass of 22.3 nmol/g. More obviously, tri-halomethane precursor(THMFP) were removed notably in thecarbon layer. Themass concentration of THMFP was reduced from 85 μg/L to 45 μg/L, while the removal rate was up to 47%.
