摘要
在畜禽粪便等有机固体废物高温堆肥化过程中,臭味排放及氮素损失已经越来越受到国内外学者的关注。阐述了堆肥化过程中氮素挥发特点及损失途径,介绍了国内外堆肥保氮除臭的三类方法:(1)堆肥过程中采取适宜的工艺条件;(2)堆肥原料中使用不同的添加剂;(3)综合处理。还对硫酸亚铁、沸石和普钙等在堆肥过程中的应用进行了综述。
Scholars have already paid more and more attention to nitrogen loss from high temperature compost system of organic solid wastes such as animal manure. This article introduces the way and characteristics of nitrogen loss and thereafter introduces three kinds of methods for reducing nitrogen loss and deodorizing: Firstly, suitable conditions adopted in the compost process; secondly, different chemical additives used in the compost; finally, synthesis process. The article also reviews the application and effect of ferrous sulfate, the zeolite and super phosphate in compost system.
