复合微生物菌剂对市政污泥堆肥中有机物质的影响

Effects of organic matters during composting of paper mill sludge

研究了复合微生物菌剂对市政污泥好氧堆肥中有机物质的影响。结果表明:添加微生物菌剂可以提高堆肥温度,延长堆肥高温期,增加有机质的降解率,对堆肥产品的pH、EC、GI和养分无显著影响,且不同微生物菌剂对堆肥有机物质的影响也不同。

This study aims to determine whether addition of complex microorganisms into paper mill sludge aerobic composting could enhance the organic matter degradation and composting process.The results showed that the temperature of composting increased,prolong the compost high-temperature period and enhance the degradation of organic.However,there were no remarkable effects on pH,EC,GI and nutrients.Overall,the treatment was more advantageous to organic matter degradation,accelerating the stabilization and humification of compost,treatment was in the second place and effects of treatment was not obvious.
