摘    要:选用杂草作为城市生活垃圾中可降解有机物的典型组分,研究了湿解参数对湿解后固体、气体和液体比例的影响,以及固体成分中有机质、黄腐酸、胡敏酸和大量营养元素的影响。结果表明,湿解应采用适当的高温和短的反应时间,如在 480 K 下湿解 0.25 h,固体成分保留最多,有机质含量最丰富,腐殖化程度最高,但大量营养元素的含量也最低。

关 键 词:湿解  可降解有机物  有机肥料

Abstract:Using weed-grass as typical component of labile organic compounds in municipal solid waste, this paper investigated proportional affection of solid, gas and liquid after different hydrother- mal degradation, and investigated content infection of the organic, humic acid, nitrogen, phosphorus, potassium in the solid under different react temperature and time. The results show that hydrothermal degradation should use properly higher reactive temperature and short reactive time, such as waste after treated under 480 K in 0.25 hour, which has the most solid holding rate, the most abundant organic content, the highest humifying degree, and the lest nutrition element.
Keywords:hydrothermal degradation  labile organic compounds  organic fertilizer
