摘要
印染废水因污染物浓度高、色度大、可生化性差成为难处理的工业废水。本文采用微电解-生化工艺对印染废水进行工程实验,微电解预处理使废水中的COD大幅去除,并显著提高其可生化性;色度问题也得到了有效解决。工程实验结果表明,微电解-生化工艺处理效果好、出水水质稳定、运行费用低,处理后废水能达标排放。
Dyeing wastewater is difficultily treated because of high concentration of pollutants, high colority and bad biodegradation. Based on an engineering experiment, this paper describes the treatment of dyeing wastewater using micro - electrolysis and biochemical method. The results showed micro - electrolysis had a better treatment effect on the COD and color removal ratio of dyeing wastewater,and the performance of biodegradation was improved. It showed that this process is efficient, stable and can save money, the effluent can meet the wastewater discharge standards.
