摘　　要：研究了铁屑在UASB处理含硫高浓度有机废水中的作用,以生活污水处理厂剩余污泥为种泥,适量加入铁屑和活性炭颗粒,实现了UASB的快速启动,并在较短的时间内(21d左右)培养出了厌氧颗粒污泥,颗粒污泥增殖速率为0.0686d-1,为不加铁屑的3.48倍,大幅度提高了污泥活性。同时成功的消除了SO42-对生物处理系统的影响,COD的去除率保持在95%以上,比对照试验结果高出65%,同时出水消除了恶臭。试验方法和结果可为类似酸性高浓度有机废水处理和工艺调试的快速启动提供参考。Scrap iron in UASB to deal with sulfur-bearing high concentrated organic wastewater has been investigated in this paper. Excess activated sludge from domestic; sewage plant served as original sludge achieve the rapid start-up of UASB successfidly by adding appropriate scrap iron and granule active carbon to UASB. Anaerobic particular sludge was cultured in a short time （about 21 days）, multiplication speed is 0.0686 d^-1 ,which is 3.48 times higher than that without scrap iron.Sludge activity has been improved. Meanwhile, the influence of SO4^2- on biological treatment system and offensive odor was eliminated, COD removal is above 95%, 65% higher than past. This rapid start-up method provides an example for disposing wastewater resembled acidic organic wastewater in high concentration.
