摘要
采用猪粪为原料,进行了不同工艺和不同填充料的堆肥试验。结果表明,改进工艺能有效去除臭味并明显缩短发酵时间;新鲜猪粪中加入锯末、干粪及菇渣作为填充料,调节初始物料含水率至65%左右,并接入合适的微生物菌剂有利于猪粪发酵腐熟;干粪和菇渣作为填充料具有相似的效果,干粪容易获得,并且处理氮的转化率更高。
An experimental research on composting swine feces was carried out, by changing technics and bulking agent. The results showed that the improved technology can shorten the ferment time obviously and deodorize manure efficiently. Adding bulking agents including sawdust, dry feces and mushroom dregs in fresh swine feces, regulating initial stock water containing ratio around 65%, and inoculating suitable bacterial preparation were in favor of the maturity of composting. As bulking agent, dry feces and mushroom dregs have similar effects, but dry feces gets easily and has higher translation rate of nitrogen.
