摘要
在使用多种染料的印染废水中,控制相应的pH,以普通的铝盐及铁盐为絮凝剂,使出水中有机物及色度达到排放标准.碱化污泥回流,可节省硫酸铝投量,改善沉渣性能,大幅度减少排渣体积,降低处理成本.
The multidyestuffs borne dyeing-printing Wastewater was treated under controlled pH value and dosed ferro-aluminate as flocculating agent to cut down the content of organic substances and colour in the effluent to the level to meet the requirement of the discharge standard. Basic sludge recycling was adopted as a''measure to save the consumption of aluminum sulfate, improve the properties of sediments, decrease in large scale the volume of discharged dregs and reduce the operating expenses.
