摘要
提出高锰酸盐复合药剂预氧化与生物活性炭联用技术处理微污染地表水.与单独生物活性炭工艺进行了挂膜对比试验研究,结果表明,高锰酸盐复合药剂预氧化促进了后续生物活性炭工艺对有机物和氨氮等污染物的去除,提高了出水水质,并缩短了活性炭的挂膜时间.由于高锰酸盐复合药剂预氧化与生物活性炭滤池联用技术投资小,对于经济有效地改善饮用水水质有深入研究价值.
A novel combined process of permanganate composite chemical (PPC) and biological activated carbon (BAC) were studied to treat polluted surface water. The comparative experiments of BAC start-up were conducted with and without PPC precxidation.The results showed that the removal rate of organic substances and ammonia was improved and start-up time was shorten by PPC preoxidation. Because of low cost, the combined process of PPC and BAC may be a potential process for treating micro-polluted surface water.
