The study was to explore the treatment of pyridine, quinoline and their transformation product, NH(4+) -N, by the biodegradation and adsorption of a natural and a modified bio-zeolites. The experiment results demonstrated that the mixed bacteria on the bio-zeolites, a pyridine-degrading bacterium and a quinoline-degrading bacterium, could degrade pyridine and quinoline simultaneously. The NH(4+) -N transformed from pyridine and quinoline could be adsorbed by the natural and modified zeolites. The adsorption capacity of the modified zeolite was lower than that of the natural zeolite. However, more microorganisms could attach on the surface of the modified zeolite, so the application of the modified bio-zeolite has a better prospect in actual treatment of pyridine and/ or quinoline pollution.
本研究旨在通过天然生物沸石和改性生物沸石的生物降解及吸附作用，探究吡啶、喹啉及其转化产物NH(4+)-N的处理方法。实验结果表明，生物沸石上的混合细菌，即吡啶降解菌和喹啉降解菌，能够同时降解吡啶和喹啉。由吡啶和喹啉转化而来的NH(4+)-N可被天然沸石和改性沸石吸附。改性沸石的吸附容量低于天然沸石。然而，更多的微生物能够附着在改性沸石表面，因此改性生物沸石在实际处理吡啶和/或喹啉污染方面具有更好的应用前景。
