采用MUCT工艺作为处理高氮磷浓度酿造废水好氧处理单元，考察装置分别处于全程硝化与短程硝化两阶段时对氮、磷元素的处理效果。全程硝化阶段，考察水力停留时间以及在缺氧Ⅰ池投加碳源改变C/N条件下工艺对酿造废水处理效果的影响，结果表明，当水力停留时间HRT为10 h、缺氧Ⅰ区C/N为6时，工艺对装置的处理效果最优，原水阶段氨氮、总磷平均去除率分别能达到66.17%和74.03%。短程硝化阶段，缩短HRT至8 h、控制DO质量浓度在0.5~0.8 mg/L，以亚硝态氮积累率（NAR）作为区分全程与短程硝化两阶段的指标，最终在混合液回流比为150%、硝化液回流比为250%、回流污泥比为90%时，成功启动短程硝化；原水阶段，NAR稳定在60%左右，氨氮去除率在50%以上，TP平均去除率达到77.94%，最高达91.59%。

MUCT process is used as an aerobic treatment unit to treat with brewing wastewater with high concentrations of nitrogen and phosphorus.In the whole-cut nitrification stage, the effects of different HRT and C/N in anoxic I tank are investigated.The results show that the process presents the best treatment effect with average removal rates of ammoniacal nitrogen and total phosphorus in raw water stage reaching 66.17% and 74.03%, respectively when HRT is 10 h and C/N in anoxic I tank is 6.As for short-cut nitrification stage, HRT is shortened to 8 h, the concentration of DO is controlled at 0.5-0.8 mg·L^-1, and the accumulation rate of nitrite nitrogen (NAR) is used as the index to distinguish whole-cut nitrification from short cut nitrification.Finally, the short-cut nitrification is successfully started up when the reflux ratio of mixed liquor is 150%, the reflux ratio of nitrification liquid is 250%, and the reflux sludge ratio is 90%.In the raw water stage, NAR remains around 60% stably, the removal rate of ammoniacal nitrogen exceeds 50%, and the average removal rate of total phosphorus reaches 77.94% with the highest at 91.59%.
