摘　　要：亚硫酸盐自养反硝化是一种新型低碳源含硝废水的处理方法,亚硫酸盐代替碳源作为电子供体被脱氮硫杆菌利用进行硫自养反硝化作用,将水中的硝酸盐去除。亚硫酸盐型自养反硝化进行反应的最佳pH为7~8,pH>8或pH<7时反硝化效果下降,当pH升至8~8.5时加入盐酸将pH调至7~8,可消除pH抑制,恢复污泥活性。本实验结果将为pH影响的亚硫酸盐型反硝化研究提供理论支持。Sulfite autotrophic denitrification is a new low-carbon source nitrate-containing wastewater treatment method.Sulfite replaces carbon source,as an electron donor,was used by Thiobacillus denitrificans to perform sulfur autotrophic denitrification and remove nitrate in water.The optimal pH for sulfite-type autotrophic denitrification was 7~8.When pH>8 or pH<7,the denitrification effect will decrease.When the pH raised to 8~8.5,hydrochloric acid was added to adjust pH to 7~8,pH inhibition and restore sludge activity can be eliminated.The results of this experiment will provide theoretical support for the study of sulfite-type denitrification affected by pH.
