预处理/水解酸化/好氧工艺处理漂染工业园废水

Treatment of Wastewater from Bleaching and Dyeing Industry Area by Pretreatment/Hydrolysis Acidification/Aerobic Process

采用预处理/水解酸化/好氧/混凝沉淀工艺处理漂染工业园废水,处理效果稳定,酸耗低,占地面积小,剩余污泥少,泥饼可直接送往园区电厂掺煤焚烧,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准。

A combined process of pretreatment, hydrolysis acidification, aerobic treatment and coagulation sedimentation was used to treat wastewater from bleaching and dyeing industry area. The combined process has advantages of stable treatment effect, low acid consumption, small occupied land area and less excess sludge, and the sludge cakes can be burned with coal in the electricity plant of the industry area. The project acceptance results show that the effluent quality can achieve the first class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
