摘要
制浆造纸工业的黑液废水污染严重,生物厌氧处理能够改善水体环境。本文探索了不同浓度的黑液在不同温度、不同p H条件下与污泥以一定的比例混合厌氧发酵10 d,考察黑液中的COD值、酸溶木质素及酸不溶木质素含量的变化,对厌氧处理条件进行效果比较和综合评价。
The black liquor wastewater in the pulp and paper industry is seriously polluted,and biological anaerobic treatment can improve the water environment.In this paper,different concentrations of black liquor were mixed with sludge at different temperatures and different pH conditions for 10 days.The changes of COD value,acid-soluble lignin and acid-insoluble lignin content in black liquor were investigated.,the effect comparison and comprehensive evaluation of anaerobic treatment conditions.
