中文摘要	印染业是最大耗水量行业之一。印染废水具有色度高、COD值大和pH值高的特点,且生产期间废水水质变化频繁。传统的化学法和生化法几乎达到技术极限,处理效果很难提高。本文通过试验首先研究了直流电絮凝法处理实际印染废水的效果,并分析了COD、pH值和色度的变化,以及电絮凝法的极板消耗和电耗等,确定了相关参数,然后进行了直流电絮凝法联合生化法处理实际废水的模拟试验。试验结果表明,电絮凝法和生化法结合可以相互补充,充分利用两种方法的优点,具有处理效果好,对pH值要求低,工艺简单,操作方便,成本低等优点,可以有效地降低印染废水的COD和色度。; Printing and dyeing industry is one of largest water consumption industries. High colourity, large COD and pH values are the main characteristics of dyeing wastewater, in which color varies frequently during the production. Conventional biochemical treatment has reached its technical limit and is hard to improve its treatment effectiveness. Firstly, treatment of real dyeing wastewater by electrocoagulation with iron or aluminium electrode was studied in a dying factory in the paper. The improvement of COD and colority, change of pH, and power and electrode consumption were analyzed and the relative parameters are selected in the paper. Secondly, the simulation experiment by combination of DC electrocoagulation and biochemical method was made in a factory and has been continued for six months. The experimental result shows that the combination method is complementary to each other and combines the advantages of two methods. It can decrease COD and colourity efficiently with wide pH arrange, simple techniques, convenient operation and low cost.
