Effects of organic matters during composting of paper mill sludge

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.
