污水高效处理和资源化的固定化微生物技术研究

采用功能化大孔载体FPUFS并以载体结合法固定化高效微生物菌群B350，所得固定化B350置于曝气池中构成一个有效容积为1500L的固定化微生物-曝气生物滤池（I-BAF）污水处理系统。通过对进水与出水氨氮（NH4^ -N）、挥发酚及化学耗氧量（COD）的检测分析，以煤气厂焦化污水的现场连续运转处理为例对I-BAF系统的处理效果进行了系统研究。研究了I-BAF系统对实际工业污水的处理性能，得出了I-BAF系统的去除COD、挥发酚和氨氮的效果曲线。结果表明：I-BAF系统对煤气厂焦化污水具有较好的处理效果，在进水COD为3450mg/L，NH4^ -N为451mg/L，挥发酚177mg/L，色度120倍时，处理出水COD为57.5mg/L，NH4^ -N.285mg/L，挥发酚0.498mg/L，色度为12。这一处理效果是现行其他方法难以达到的，因此本研究对污水的高效处理和资源化具有重要的意义。

Application of Immobilized Microorganisms in Efficient Wastewater Treatment and Reuse

This paper studies the treatment effect of the coking wastewater by use of a 1500L sized I-BAF system, which is based on immobilized microorganisms and enzymes, B350, on certain synthesized polymer carrier. Analysis of the influent and effluent NH4+ -N, phenol and COD is carried out. As results, relevant performance curves are obtained, which show the wastewater treatment effect through the I-BAF system particularly in removal of COD, phenol and ammonia-nitrogen. For the coking wastewater, the I-BAF system has excellent treatment effect. In case that the influents COD =3450mg/L, NH/-N =451 mg/L, phenol = 177 mg/L and chroma = 120, the corresponding effluents are 57.5mg/L, 0.285 mg/L, 0.498 mg/L and 12, respectively. This effect could hardly be obtained with other conventional technology, and thus significance in efficient treatment and reuse of wastewater.
