摘要
为了实现校园垃圾的资源化利用,在分析了校园垃圾中可堆肥类物质含量的基础上,提出了蚯蚓堆肥技术处理校园垃圾制作有机肥料的工艺,同时,对蚯蚓堆肥获得的有机肥料和传统堆肥获得的有机肥料的养分进行了比较,研究了蚯蚓堆肥工艺中厌氧降解阶段有机质降解的适宜条件。结果表明,蚯蚓堆肥获得的有机肥料的养分为6.85%,高于传统堆肥获得的有机肥料的养分;在接种量为10%、pH中性、温度为40℃、碳氮比为30∶1和初始含水量为60%的适宜条件下,厌氧降解阶段有机质降解率达到38.77%。
In order to achieve resource utilization of campus refuse,the process of manufacturing organic fertilizer with campus refuse using earthworm composting technique was suggested after analyzing the content of compostable material in campus garbage.The nutrients contents of the fertilizers made by the earthworm composting technology and by traditional composting technology were compared.Then the optimum conditions of organic matter degradation during anaerobic degradation were studied.The results showed that the nutrient content of fertilizer by the earthworm composting technology was 6.85%,which was higher than that by the traditional composting technology.When the inoculation amount was 10%,the pH was neutral,the temperature was 40 ℃,the ratio of carbon to nitrogen(C / N) was 30∶1,and the initial moisture content was 60%,the degradation rate of the organic matter during anaerobic degradation could reach 38.77%.
