污泥用量对生活垃圾堆肥氮素转化与损失的影响
Effects of sludge amount on nitrogen transformation and loss during municipal solid wastes composting
摘要
Abstract
Unmixed municipal solid waste MSW（group A）,sludge mixed with MSW 1∶ 6（group B） and 1∶ 4（group C） were composted to investigate the nitrogen loss in the process of MSW composting under high temperature and aerobic conditions.The effects of sludge amount on temperature,pH,nitrogen transformation and loss during composting were studied.The result shows that addition of sludge affects the ventilation performance of MSW,slows down the heating rate and extends the composting period,but has no effects on pH.Addition of sludge is beneficial to the accumulation of ammonium and nitrate content,the maximum accumulation of ammonium and nitrate content increased as the amount of sludge increased,which is contributed to reserve nitrogen.Addition of sludge can reduce the loss of organic nitrogen and total nitrogen during MSW composting.Addition of sludge can effectively reduce the nitrogen loss during MSW composting,but the ratio of nitrogen loss increased with the amount of sludge increased furtherly,so the optimal amount of sludge added into MSW composting process should be further studied.关键词
