摘要
采用水解酸化/接触氧化/气浮/砂滤+精滤/超滤/反渗透工艺处理针织印染废水,运行结果表明该工艺对废水中COD、色度、悬浮物等各项指标去除率达到95%以上,回用水水质完全满足针织印染工艺的需求。该工艺产生的污泥很少,且回用水的运行成本远远低于新鲜水和废水处理的费用之和,给企业带来较好的经济效益。
The combined process of hydrolysis acidification/contact oxidation/DAF/sand filter and fine filter/UF/RO was applied to treat knitting & dyeing wastewater. The result showed that over 95% of influent COD, chromaticity, SS and other pollutants could be removed by the process. The recycled water could meet the requirements of knitting & dyeing. Besides, little sludge was produced in this process and the operation cost of recycled water was much less than the total cost of corresponding fresh water and wastewater treatment, which brought much economic benefit for the enterprise.
