摘要
通过中试试验，考察了EM除臭剂对生活垃圾和污水污泥的除臭效果。研究发现：喷洒0．1％EM除臭剂可使生活垃圾卫生填埋场的硫化氢和氨气浓度均小于GB14554的III级标准，效果稳定可靠。同时，EM除臭剂可大幅度改变污泥的微生物体系，显著改善污泥的恶臭气味，并确定EM菌剂的最佳添加量宜为0．3％～0.5％。
A pilot study of deodorant effect for domestic waste and sewage sludge using EM deodorizer was carried out. The resuhs showed that the concentrations of hydrogen sulfide and ammonia from domestic waste landfill sites can meet the level III of GB 14554 standard in 1‰ EM deodorizer, which indicated that EM deodorizer was reliable and stable. Meanwhile, EM deodorizer could greatly change microorganism system and significantly improve odor for sludge, and the optimal addition of EM deodorizer was 0. 3%-0. 50%.
