【摘要】 土霉素结晶母液是一种含高硫高氮的高浓度难生物降解有机废水 ,采用前置反硝化法对其进行脱氮处理 .实验结果表明 :废水中有机物浓度相对于氮量明显不足 ,而且残留土霉素等对反硝化有明显的生物抑制作用 .对废水进行适当的酸化预处理 ,可以显著地缓和废水的生物抑制性 ,提高其反硝化能 .预酸化 前置反硝化工艺处理土霉素结晶母液是可行的 .更多还原

【Abstract】 Terramycin crystal mother solution contains high concentration of nitrogen as well as carbon. Nitrate utilization rate test showed that the contents of organic compounds in raw wastewater were not sufficient for complete denitrification. Anaerobic pretreatment was found to be effective for increasing the denitrification potential of the solution. The results indicated that it was possible to remove nitrogen from terramycin crystal mother solution using pre\|denitrification process.更多还原
