本文提出了一种对高浓度、高色度、难降解有机废水的经济有效的预处理方法。废水经过微电解—中和絮凝工艺处理后,有机物种类和数量明显减少,可生化性提高。同时,脱色率可达90%以上,COD去除率在50%左右。对影响反应工艺的有关因素及处理进行了分析讨论并提出了反应机理。
This paper presents a cost-effective pretreatment method for high-concentration, high-color, refractory organic wastewater. Wastewater after micro-electrolysis - and flocculation process, the type and quantity of organic significantly reduced, biodegradability increased. At the same time, the decolorization rate of up to 90%, COD removal rate of about 50%. The factors affecting the reaction process and the treatment are analyzed and discussed and the reaction mechanism is proposed.
