| 摘 要： | 堆肥化处理是实现园林绿化废弃物资源化利用的有效方式。为探索堆肥化处理技术,笔者研究了在不同量物质(落叶、活性污泥、土壤)的园林废弃物堆肥中C、N含量的变化规律。试验结果表明:堆腐过程中全碳含量总体呈下降趋势,而全氮含量总体变化趋势为嗜热阶段急剧上升,低温腐熟保肥阶段增加减缓。碳氮比在堆肥化处理过程中呈下降趋势。经正交试验分析,1000 g园林废弃物中加入800 g的污泥的处理E和处理H最有利于堆肥的腐熟,得到的腐熟肥碳氮含量较为合理,其碳含量分别为413.59 g/kg和611.16 g/kg;氮含量分别为17.57 g/kg和21.95 g/kg;碳氮比为23.54和27.84。

| Abstract: | Composting is an effective way to utilize the resource of garden waste. In order to explore the composting process, the authors studied the change rule of nitrogen and carbon content in different amount of garden green waste composting. The results showed that the total carbon content generally had a declining trend, and the total nitrogen content increased rapidly in thermophilic phase, while increased slowly in low temperature composting phase. Carbon nitrogen ratio decreased in the process of composting. The results of orthogonal test showed that treatments E and H with 800 g sludge added into 1000 g garden waste were advantageous to the composting rotten, which had rational C content of 413.59 and 611.16 g/kg and N content of 17.57 and 21.95 g/kg, and the carbon and nitrogen ratio was 23.54 and 27.84, respectively. |
