摘要:

从武钢焦化废水活性污泥中分离筛选出1株能以吡啶为唯一碳源和氮源生长的高效降解菌,考察了吡啶初始浓度、接种量、pH值、温度和金属离子等因素对菌株降解特性的影响。实验结果表明,该菌株对吡啶耐受力较强,可达1 200mg/L。吡啶降解适宜条件为30℃,pH7.5和接菌量5%,投加适量Fe2+可促进吡啶降解。

Abstract:

One high-efficient degrading strain which took pyridine as only carbon source and nitrogen source was separated and screened from activated sludge of coking effluent of WISCO, the influence of the factors such as pyridine initial concentration, inoculum size, pH value, temperature and metal ion on strain degradation property was studied. The test results showed that this strain had stronger resistance on pyridine, which can be 1 200mg/L. The suitable condition for pyridine degradation was 30℃, pH 7.5 and inoculum size 5%, if suitable Fe2+ was added, the pyridine degradation could be promoted.
