摘要/Abstract

摘要： 洗涤黑液是精制棉生产的压榨洗涤工艺产生的废水，将其单独进行生化处理的研究较少。为了探索洗涤黑液生化处理的方式和程度，采用1 m³/d的中试规模，分别利用两级厌氧-好氧和直接好氧工艺生化处理洗涤黑液。结果表明，两种方式均可将洗涤黑液的化学需氧量（COD）由1 100 mg/L左右生化处理至330 mg/L左右，再经体积比为2.5‰投药量的硫酸铝混凝后COD可稳定降至100 mg/L以下，色度达到50倍以下。洗涤黑液在厌氧处理过程会发生硫酸盐还原而产生臭气，影响生化系统微生物活性。因此，洗涤黑液适宜采用直接好氧-硫酸铝混凝处理，可稳定达到国家污水综合排放标准的一级标准。

Abstract: Washing black liquid is a kind of waste water produced in the pressing and washing processes of refined cotton. Separate treatment of washing black liquid is relatively rare. In order to explore the degree and method of washing black liquid biochemical treatment, the two-stage anaerobic-aerobic and single aerobic processes are used to treat the washing black liquid in the pilot scale of 1 cubic meter per day. The result shows that COD of washing black liquid can be reduced from 1 100 mg/L to 330 mg/L in biochemical treatment. With the coagulation of further aluminum sulfate which optimum dosage is 2.5‰(volume ratio), COD of washing black liquid is decreased to less than 100 mg/L and the chroma achieves less than 50 times. Stench is created by sulfate reduction in the anaerobic treatment process, which decreases the activity of microorganism. Therefore, the washing black liquid is suitable for the direct coagulation treatment of aerobic-aluminum sulfate.

Key words: environmental engineering, washing black liquid, anaerobic process, aerobic process, sulfate
