摘要
用高效混凝过滤法处理草类制浆黑液,混凝净化后的黑液与中段废水及部分白水一起采用活性污泥法处理。
A treatment technology of black liquor and bleaching liquor from straw pulping process was studied in the paper. Firstly, the black liquor was treated by flocculation and filtration methods. And lignin and suspension solid etc were separated out. Then clear black liquor was mixed with bleaching liquor and treated with activated sludge process. The final flow had COD below 400 mg/L and could meet the demand of Chinese Pollution Effluent Standard in pulping process.
