Sorting garbage,Study on Nitrogen Transformation and loss during mixed composting of municipal solid waste and sewage sludge in vegetable market
Abstract
Two groups of High Temperature Composting experiments were designed.,Waste and decomposed sludge sorted by mass ratio1.:1.Mix, BGroup sorting garbage,Quality ratio of waste and decomposed sludge in vegetable market1.:1.:1.Mix.The results show that: A, BThe temperature of the two groups is larger55Not less than the time3D,Meet hygienic requirements,Harmless Treatment, BHigh temperature duration ratioATeam Leader10d.During Composting, A, BTwo groups of heapsTNAnd organic nitrogen decreased gradually.,Ammonia Nitrogen increased first and then decreased,Nitrate Nitrogen has been risingA, BTwo groups of heapsN2.OThe release mainly concentrated in the pre-composting period.,Before Composting7.TianN2.OOf the total amount90%Above,During CompostingBNitrogen loss rate was30.65%,LowerANitrogen Loss Rate48.02% ).
