摘要
以城市生活污水剩余污泥为主要原料,按3种不同体积比添加猪粪和木屑进行好氧堆肥研究。结果表明,3种处理均能实现剩余污泥的无害化、减量化和资源化。从堆体温度、pH值和含水率3个指标看,堆肥前期16 d是堆肥的快速反应阶段,第16天后堆肥基本处于后腐熟阶段。从全氮和种子发芽率指标看,堆体C[V(污泥)︰V(猪粪)︰V(木屑)=55%︰22.5%︰22.5%]的氮损失最少,堆肥腐熟程度最高。
Aerobic composting was carried out with 3 different volume ratios of sewage sludge,pig manure and sawdust.The results showed that three treatments all can realize harmlessness,minimization and recycling.According to the pile temperature,pH and moisture content,former 16 d was the fast reaction stage,and after that was rotten stage.The results of total nitrogen and germination index showed that nitrogen loss of pile C was the least with the volume ratio of sewage sludge,pig manure and sawdust as 55%∶22.5%∶22.5%,and the rotten degree of pile C was the highest in three piles.
