Apply Jute Fiber to Enrichment the Microorganism for Purification the PAHs in Water

Abstract

AbstractThe research on effects of purifying the PAHs in water is to apply a plant material which is jute fiber to enrichment the microorganism for purificationthe PAHs. The results of this research turns out that the jute fiber material has better effect of purifying the PAHs in water, and the purificationeffects are highly related with jute fiber’s layout density, HRT and aeration rate. The higher the layout density of jute fiver, HRT and aeration rate, the better the effects of purification, which means the water quality of effluent meets the GB5749-2006 standard that the total content of PAHs is less than 2000 ng·L-1 . With the same density of jute fiver or HRT or aeration rate, the purifying rate is significantly around 3% less with large ring PAHs than with small ring PAHs in water. The number one water tank with jute fiber, 12h HRT and 6 h aeration has the best purifying effect. Therefore, the jute fiber can better purify the PHAs in water.KeywordsPlant fiberOrganic PollutantsPAHsMicroorganism
