【摘要】：以喹啉為唯一碳氮源從某焦化廢水處理廠活性污泥中篩選出一株喹啉降解菌菌株紅球菌(Rhodococcus sp.)KDQ2,其在24h內(nèi)能將400mg/L喹啉降解96%,降解的最適條件為37℃和pH6~9,降解動力學符合Haldane方程.KDQ2能利用吡啶,但不能利用苯酚;在喹啉、吡啶和苯酚共存條件下,150mg/L吡啶和400mg/L苯酚不影響150mg/L喹啉在1d時的降解效率.KDQ2能適應含有高濃度苯酚、吡啶和喹啉等污染物的焦化廢水環(huán)境條件,可以與活性污泥中的微生物共存,提高實際焦化廢水中喹啉和TOC的去除能力.
[Abstract]:With quinoline as sole source of carbon and nitrogen from coking wastewater treatment plant of quinoline degrading bacterium, Rhodococcus strains were screened from activated sludge plant (Rhodococcus sp.) KDQ2, the 400mg/L 96% 24h in quinoline degradation can be the optimum conditions for the degradation of pH6~9 and 37 DEG C, the degradation kinetics conformed to Haldane equation.KDQ2 can use pyridine, but cannot use phenol; in quinoline, pyridine and phenol under the condition of coexistence of 150mg/L and 400mg/L, pyridine phenol does not affect the degradation efficiency of.KDQ2 150mg/L in 1D can adapt to quinoline containing high concentrations of phenol, pyridine and quinoline coking wastewater pollutants such as environmental conditions, can coexist and microorganisms in activated sludge, improve the ability of removing quinoline and TOC the actual coking wastewater.
