摘　　要：由于部分南方城市污水低碳源这一现状,在污水处理反硝化阶段,寻求聚酯废水作为外加碳源的最佳投加方式和最佳投加量。以5‰甲醇溶液作为外加碳源进行基础实验,研究结果表明:1)外加碳源连续投加效果最好;2)外加碳源的投加量以满足反硝化碳源需求为限制条件,就实验的聚酯废水而言,最佳投加量约为处理水量的2%,从而替代投加量约为处理水量2%的5‰甲醇溶液,实现了以废治废,提高了污水反硝化处理的经济性。Based on the status quo that carbon source of urban wastewater in the southern China is generally low, the most optimum dosing method and dosage of polyester wastewater used as additional carbon source were investigated in the stage of sewage denitrification. Basic experiments of adding5‰ methyl alcohol as an additional carbon source were made. The results showed that： 1） Continuous dosing of additional carbon source could reach the best effect; 2） Dosage of additional carbon source was restricted to the demand of denitrification carbon source. As to polyester wastewater in the experiment, the wastewater could be used for the replacement of 5 ‰ methyl alcohol with the most optimum dosage accounting for about 2% of treated wastewater. It realized the treatment of waste with processes of wastes against one another and improved the economic benefit of the sewage denitrification process.
