一体化反应器协同处理生活垃圾与污泥启动试验研究
Set-up experiment of integration reactor for coordination treatment of domestic garbage with sewage sludge
摘要
Abstract
Based on the self-developed integrative reactor for treating municipal solid waste (MSW) and sewage treatment plant sludge (STP sludge), a start-up experimental study on MSW composting and anaerobic thickening and digestion of STP sludge was carried out. The results indicate that at the ambient temperature of 17 ℃ to 28 °C, the temperature of refuse processing vessel maintains between 17℃ and 30℃; with a pH ranging from 3 to 6, temperature in the sludge digestion vessel is basically stable between 15℃ and 30℃; with a pH ranging from 5.5 to 7.4, the Sv/ST of influent sludge is between 0.40 and 0.80 while that of discharged sludge descends to 0.30-0.45; the moisture content of discharged sludge is quite changeable, however, it becomes more stable at around 92% compared to the influent moisture content of 98.6% to 99.8% after 30 d. The integrative reactor has realized the co-processing of MSW and STP sludge together. It provides sludge thickening and digestion with high temperature conditions by making use of refuse composting heat. The integrative reactor, however, still remains to be improved.关键词
