摘　　要：通过在实验室内模拟目标企业废水的生物处理过程,探究前置反硝化工艺对处理企业的高硝酸盐氮废水的有效性及采用该企业其他高COD废水作为反硝化所需碳源的可行性。实验表明,前置反硝化工艺路线可有效降低该废水中的氮;利用高COD废水与甲醇按比例混合作为碳源,既可达到良好的脱氮效果,又能更好地降低运营成本。The biological treatment process of wastewater from the target enterprise is simulated in the laboratory to explore the effectiveness of pre denitrification process for the treatment of high nitrate nitrogen wastewater of the enterprise and the feasibility of using other high COD wastewater of the enterprise as the carbon source required for denitrification.The experimental results show that the pre denitrification process can effectively reduce the nitrogen in the wastewater.Using high COD wastewater mixed with methanol in proportion as carbon source can not only achieve good denitrification effect,but also better reduce the operation cost.
