城市污泥中富含具有内分泌干扰活性的壬基酚(NP)和短链壬基酚聚氧乙烯醚(NP2EO、NP1EO)。污泥堆肥土地利用是国内外城市污泥最重要的处置方式。通过在污泥中添加促腐剂后堆肥发酵,进行了壬基酚类物质的变化研究,研究发现:从壬基酚二氧乙烯醚(NP2EO)、壬基酚单氧乙烯醚(NP1EO)和NP这3种物质总量的降解效果来看,好氧发酵优于厌氧发酵;好氧发酵过程中添加促腐剂对消除壬基酚和壬基酚聚氧乙烯醚(长链NPnEO,短链NP2EO、NP1EO)类物质是有利的。对污泥中壬基酚类物质的污染控制具有一定的指导意义。
Urban sludge is rich in nonylphenol (NP) and short chain nonylphenol polyoxyethylene ether (NP2EO, NP1EO) with endocrine disrupting activity. Sludge compost land use is the most important disposal method of municipal sludge at home and abroad. Through the compost fermentation after the addition of the preservative in the sludge, the change of nonylphenol was studied. It was found that from nonylphenol ethylene oxide (NP2EO), nonylphenol monooxyethylene (NP1EO) and NP total degradation of these three substances point of view, aerobic fermentation is better than anaerobic fermentation; aerobic fermentation process to add preservatives to eliminate nonylphenol and nonylphenol ethoxylates (long-chain NPnEO, short Chain NP2EO, NP1EO) substances are advantageous. It has certain guiding significance to the pollution control of nonylphenol in sludge.
