摘要
针对高色度、高浓度、难降解的印染废水在进行好氧生化接触氧化法处理前的处理进行研究探讨.通过运行数据分析:在好氧生化处理前增加一个2级水解酸化过程,对废水的可生化性具有明显提高,同时还大大降低了废水的pH值.
Dyeing wastewater is high in chroma as well as concentration and refractory. This paper focuses on the treatment of it, which is before aerobic bio-contact oxidation treatment. It is proved that biodegradability of dyeing wastewater improves apprently while its pH value reduces greatly if we add a process of stage two hydrolysis acidification before aerobic bio-contact oxidation treatment.
