Municipal sludge was collected from Baisamen Sewage Treatment Plant in Haikou and inoculated with a compound microorganism agent screened by Hainan Nongfengbao Fertilizer Co., Ltd. to investigate its fermentation during composting. The results showed that the compound microorganism agent increased obviously the temperature of the sludge compost during early period of fermentation, extended high temperature period for killing harmful pathogenic bacteria and roundworm eggs, accelerated dehydration of compost materials and the maturity of composting. As compared to the control, the sludge inoculated with the compound microorganism agent increased its fermentation temperature rapidly, 10～15 ℃ higher than that of the control, showed the highest temperature 5 days earlier, had the moisture content about 10% lower and arrived at the composting maturity 20 days earlier. The composted sludge had no bad smell, and had a total viable bacterial count of 2×10~9cfu/g which accords with the demands of the national standard of GB 20287-2006 and could hence be used as a fermenting agent for the treatment of municipal sludge on a large scale.
