中文摘要：

采用一体内循环生物流化床反应器处理青岛啤酒厂的生产废水。在温度为（20±2．5）℃、进水pH值为5～6．2的条件下，反应器稳定运行26d，运行期间监测了进出水COD、氨氮、浊度等参数。结果表明，反应器对COD的去除率为88％～98．46％；对氨氮的去除率保持在80％以上，最高可达91．41％；对浊度的去除率为84％～99％；容积负荷最佳值为0．63kgCOD／（m^3·d）；污泥负荷最高可达1．37kgCOD／（kgMLSS·d），最佳值为0．47kgCOD／（kgMLSS·d）；曝气量以0．3～0．4m^3／h为最佳。反应器运行阶段，在沉淀区可形成8～10cm厚的污泥层，污水进入此区域与很高体积浓度的粗粒絮体接触，形成一个微型澄清池系统，该系统可使出水浊度稳定在100NTU以内，最低可达2．1NTU，反应器运行稳定后对浊度的去除率高达99％。整个运行期间，反应器出水水质达到城镇二级污水处理厂一级标准。

英文摘要：

An integrated inner circulation biological fluidized bed reactor was used to treat the Qingdao Brewery wastewater. The reactor was steadily operated for 26 d under the conditions of tempera- ture of （20 ±2.5 ） ℃ and pH of 5 to 6.2, and the parameters of COD, ammonia nitrogen and turbidity were monitored. The conclusions were as follows ： The removal rate of COD was 88% to 98.46%. The removal rate of ammonia nitrogen was maintained at above 80% , even up to 91.41%. The removal rate of turbidity was about 84% to 99%. The optimal volumetric loading was 0.63 kgCOD/（ m3 · d）. The maximum sludge loading was 1.37 kgCOD/（ kgMLSS · d）, with the optimal value of 0.47 kgCOD/ （ kgMLSS · d）. The optimal aeration rate was 0.3 to 0.4 m3/h. A layer of sludge with thickness of 8 to 10 cm could be formed in the settling zone. Wastewater entered this zone to contact with the coarse floc with high volume concentration, which formed a miniature clarifier system. The system could make the effluent turbidity less than 100 NTU, with a minimum of 2.1 NTU. During the whole operation period of the reactor, the effluent quality could meet the first level standard of the secondary urban sewage treat- ment plant.
