摘要
以长江南京段原水为研究对象,以提高水处理出水水质和生物稳定性为目标,研究了生物活性炭工艺对有机物指标和氯苯类化合物的去除效果,并从有机物分子量的角度研究了生物活性炭工艺对有机物的去除机制。中试试验结果表明:生物活性炭工艺能有效地去除水中的有机物,对CODMn,UV254,溶解性有机碳(DOC)及可生物降解溶解性有机碳(BDOC)的去除率可分别达到52%,50%,40%和82%,对氯苯类化合物的去除效果也较为明显,去除率为40%左右。生物活性炭工艺对各个分子量区间的去除效果都比较好,对原水中占多数的小于1k的溶解性有机物(DOM)去除效果尤为显著。
This paper introduced the removal efficiency of organic and chlorobenzene compounds using biological activated carbon process which was adapted for Nanjing raw water for the purpose of raising up the water quality and biological stability. It also studies the removal mechanism of organics from the view of molecular weights of organic matters. The statistic of the experiment shows that the process would remove organic matters effectively. The removal efficiency of CODMn, UV254, DOC and BDOC of the process is about 52 %, 50 % 40 % and 82 % of the original data respectively. The process also shows a great ability in removing the chlorobenzene compounds which has been removed over 40 % during it. In addition, the process is good dealing with DOM whose molecular weight is less than lk Dalton.
