调理剂在猪粪处理中的除臭及保氮作用

Odor Reduction and Inhibitor of Nitrogen Losses by Chemical Amendments During Composting Pig Manure

通过室内培养与室外堆肥试验，研究了添加调理剂对猪粪发酵过程中臭味及氮素损失的影响。结果表明，添加调理剂可以减少猪粪发酵中氨与硫化氢的挥发，减轻氮素损失与猪粪的恶臭。使用本研究中所采用的发酵剂与发酵工艺， 75％含水量的猪粪经过 15 d的发酵，可达基本腐熟程度。

Experiments with indoor incubation and outdoors pilot composting were carried out to investigate effects of chemical amendments on odor reduction and inhibitor of nitrogen losses during composting pig manure. The results suggested that chemical amendment used has decreased the amounts of both NH3 and H2S cumulative volatilization for 15 days－ incubation, respectively. With our operation procedure, the composts of pig manure with 75％ moisture for 15 days were available for application into soil.
