摘要
印染废水难以生物降解,传统的好氧生物处理方法效果不理想。"水解酸化"在提高废水的可生化性、色度去除率以及后续好氧处理效果等方面具有独特的优越性。采用水解酸化—接触氧化—混凝工艺处理印染废水,有机物和色度能得到有效去除,处理后出水水质好,能达到《纺织染整工业水污染物排放标准》(GB4287-92)中一级标准要求。
It is dittScult to biodegrade the printing and dying wastewater, so the traditional aerobic biological treatment is not effective. ＂Hydrolytic -Acidify＂ biological treatment is advantageous in many aspects, such as improving the biochemiealization of wastewater and the rate of chroma -wiping, reinforcing the effectiveness of the aerobic biological treatment. The organic contaminant and chroma are removed effectively by hydrolytic acidification -contact oxidation - coagulation process. The quality of the water after treatment can meet the requirements of the First Grade Discharge Standard of Water Pollutants for Dyeing of Textile Industry （ GB4287 - 92）.
