采用Anammox颗料污泥工艺对酵母废水进行脱氮处理的研究

本实验采用先进的厌氧氨氧化（Anammox）颗粒污泥工艺对某酵母厂的二沉出水进行了毒性实验与连续流实验.毒性实验结果表明该类废水对Anammox细菌有一定的抑制作用,但没有影响最终的去除效果;而近一个半月的连续流实验数据则表明：在进水氨氮浓度300～360mg/1的情况下,污泥负荷与容积负荷可以稳定地上升,出水氨氮在50mg/l以下,亚硝酸盐氮维持在5mg/l左右,氨氮去除率可这80%以上.

Research on Anammox granular sludge to treat the yeast wastewater for nitrogen removal

Use the advanced Anammox granular sludge to do the toxicity test and continuous lab test on the effluent of the 2nd clarifier from the WWTP of a yeast plant. The toxicity test indicated that such kind of wastewater has a certain restrain function on the Anammox bacteria, but doesn＇t affect the final removal purpose. The result of the continous lab test indicated： the concentration of the influent ammonia is 300-360mg/l, after more than 45 days operation, the SLR and VLR can be increased steadyly, the effluent ammonia is less than 50mg/l, the effluent nitrite is about 5mg/l, the removal efficiency of ammonia is above 80%.
