氧化塘-物化法处理造纸黑液废水

Treatment of Black Liquor from Paper Mill Using Oxidation Plus Chemical and Physical Method

采用氧化塘 -物化法处理造纸黑液废水 ,取得了良好的处理效果。处理后废水达到GB3544 -92《造纸工业水污染物排放标准》Ⅱ级标准 ,摸索出黑液中段废水的低成本处理方法 ,为黑液中段废水防治耗损提供了一项实用技术。

Oxidation plus chemical and physical method are used to treat paper mill black liquor. The industrial experiments have been done and the optimum operation conditions of the treatment process are determined. The result shows that the water quality of the effluent can meet grade-Ⅱ of Water Pollutant Emission Standard for Papermaking Industry (GB3544-92) and cost of the wastewater treatment is the cheapest in comparing with the others.
