畜禽粪便无害化处理的模拟试验

目的]利用厌氧发酵方法对畜禽粪便进行无害化处理。方法]优化发酵罐内混合料的初始温度、水分含量、pH值、C/N、C/P等特性参数,对物料进行了厌氧发酵试验,最后测定物料的养分含量。结果]最终产物养分N、P和K含量分别为1.78%、1.69%和1.86%,均高于农用控制标准。结论]该厌氧发酵试验方法设备简单、操作方便、养分含量高、反应周期短,有助于禽畜粪便的无害化处理。

Simulation Test on Innocuous Treatment of Livestock and Poultry Manure

Objective] The aim of this research was to study innocuous treatment of livestock and poultry manure using anaerobic fermentation.Method] Anaerobic fermentation of mixture in fermentor and its parameters optimization,including initial temperature,moisture content,pH value,C/N and C/P,were performed and then nutrient content of the mixture was determined in the end.Result] The results showed that the nutrient contents of N,P and K were 1.78%,1.69% and 1.86% respectively and higher than agricultural-contro...
