摘要
中小型点源污染的控制是提高水环境质量和解决水资源短缺的关键。一体式悬浮载体生物流化床(ISCBFB)占地面积小、处理效率高,适合中小型点源污水的处理。以公牛啤酒厂废水为试验原水进行了研究,试验期间进水COD平均浓度1 213.38 mg/L,出水平均为50.75 mg/L,平均去除率达到95.82%。进水氨氮平均浓度为22.50 mg/L,出水平均为4.31 mg/L,平均去除率达到80.99%,试验中全部出水水样COD及氨氮浓度均达到国家《污水综合排放标准》(GB 8978-1988)一级标准。总之,一体式悬浮载体生物流化床对啤酒废水具有很好的去除效果。
The control of small and medium size point pollution sources is the key of improving water quality and solving the issue of water resource shortage. The removal efficiency of integrated suspended carriers biological fluidized block （ISCBFB） is high and it is suitable for point pollution source treatment with little occupation. The treatment efficiency of beer wastewater using ISCBFB based on the wastewater from GongNiu Beer Company was studied. The average COD concentrations of the influent and effluent are 1 213.38 mg/L and 50.75 mg/L respectively and the removal rate can reach 95.82% . Also the average NH4^＋-N concentrations of the influent and effluent are 22.50 mg/L,and 4.31 mg/L respectively and the removal rate can reach 80.99%. All the water quality index of the effluent can reach the first class of wastewater discharge standard. It shows that ISCBFB is feasible for beer wastewater treatment.
