羊粪好氧堆肥处理研究进展

A Review of Aerobic Composting Treatment of Goat /Sheep Manure

随着我国集约化养羊的快速发展,由此产生的大量羊粪带来了很大的环境压力。而好氧堆肥是一种利用好氧微生物发酵使羊粪转变为有机肥料并达到无害化处理的有效方法。从羊粪的特点着手,对羊粪好氧堆肥原理、过程影响因素、腐熟指标、现行工艺进行了总结和分析。分析结果表明:羊粪颗粒具有较好的表面致密形态,为堆肥堆体的通风提供了良好的工艺条件;采用生物接种强化好氧堆肥过程是一项有效的羊粪无害化、资源化处理的新工艺。

With the development of larger and larger goat/sheep farm scale, its manure has become a concern of the environmental protection. However aerobic composting is an effective method to treat the manure, which can change it through aerobic microorganism into organic fertilizer. Firstly, the physico-chemical property of the manure was investigated, then the mechanism, effect of process pa- rameters, index of full decomposition of aerobic composting of goat/sheep manure were reviewed. Be- cause of the dense surface and regular shape of goat dung particles, the combination of aerobic corn- posting and inoculating microorganisms should be taken for the harmless treatment and resourceful use of goat dung in the future.
