摘要
根据实验室小试的效果,设计建设部份培植美人蕉的地表漫流田,对经二级生化处理以染整废水为主要的工业区综合污水进行深度处理,获得良好效果,第一年COD去除率平均为29.6%;色度去除率平均为26.6%。随着漫流田运行时间延长,处理效果显著提高,运行2年后,COD去除率平均为49.6%;色度去除率平均为41.8%。出水优于国家综合排放一级标准,可供养殖锦鲤,灌溉花木及间接回用作为制备工业自来水。
Based on the laboratory test, a deep treatment of industrial comprehensive wastewater which comprised mainly the dye-waste and has been treated by 2-stages treatment was designed and built with canna field of surface flow. The average reduction of COD was 29.6%, deduction of color degree was 26.6% in the first year. With the time elongating, treatment result became better and better. After continuous running of two and a half years, average reduction of COD was 49.6%, reduction of color degree was 41.8%. The quality of final effluent was higher than the national first grade standard and can be used to breed fish, for irrigation and as water resource for industrial purpose.
