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。
Taking the raw water in the Nanjing section of the Yangtze River as the research object, with the goal of improving the effluent quality and biological stability of the water treatment, the removal efficiencies of organic substances and chlorobenzenes by the biological activated carbon process were studied. The biological activated carbon technology Removal of organic matter mechanism. The pilot-scale test results show that the bio-activated carbon process can effectively remove organic compounds in water, and the removal rates of CODMn, UV254, dissolved organic carbon (DOC) and biodegradable dissolved organic carbon (BDOC) can reach 52% %, 40% and 82%, the removal of chlorobenzene compounds are also more obvious effect, the removal rate of about 40%. The bio-activated carbon process has better removal efficiency for each molecular weight range, especially for the removal of dissolved organic matter (DOM) less than 1k in the raw water.
