混凝-水解酸化-接触氧化-脱色工艺处理印染废水及回用

印染废水具有水量大、色度高、有机物含量高、可生化性较差等特点,采用混凝-水解酸化-接触氧化-脱色工艺处理某印染公司污水,经过实践证明,处理后出水水质稳定,操作管理方便等,出水直接回用到印染车间,提高了公司回用水的比率,具有较大的经济效益和社会效益,所以这处理工艺在印染废水处理及回用方面具有巨大的应用价值。

COAGULATION-HYDROLYSIS-CONTACT OXIDATION-DECOLORIZATION OF DYEING WASTEWATER AND REUSE

Printing and dyeing wastewater is of high quantity, high chroma, high organic con- tent, low biodegradability and other characteristics, the coagulation - hydrolytic acidification - contact oxidation - a printing and dyeing wastewater decolorization process, practice has proved, the quality of treated water stability, convenient operation and management, water di- rectly back to the use of printing and dyeing workshop, improves the ratio recycle water, it has great economic benefit and social benefit, so this process has great value of application in printing and dyeing wastewater treatment and reuse.
