固定化优势菌种处理焦化废水中几种难降解有机物的试验研究

Degradation of several refractory organics in coke plant wastewater by using immobilized dominant microorganism

针对焦化废水中的３种难降解有机物（喹啉、异喹啉、吡啶）筛选了具有效高降解能力的优势菌种。采用无纺布－ＰＶＡ复合载体对优势菌种进行包埋固定。研究了包埋固定化优势菌种对相应有机物的降解特性。结果表明，经优势菌种处理８ｈ，３种难降解有机物均可降解９０％以上。

Three refractory organic compounds contained in coke plant wastewater, namely, pyridine, quinoline and iso-quinoline, were used for cultivating microorganism. Dominant species were obtained and entraped by a co-immobilization material of PVA-Unwoven cloth. The degradation charateristics of these refractory organics in use of immobilized dominant microorganism were studied. The results showed that 90% of organics could be removed.
