摘要
为实现北京奥林匹克森林公园内的固体废物无害化和资源化,以粪渣与树叶为原料,进行了不同湿基比(含有实际水分的粪渣与树叶的质量比)的静态好氧堆肥试验。以堆体温度、二氧化碳含量、发芽指数、肥效指标氮磷钾以及重金属质量分数等指标来选择粪渣和树叶的最佳配比。结果表明:在粪渣与树叶含水率分别为80%和8%左右时,粪渣与树叶的湿基比为4¨1和3¨1时均可实现好氧堆肥,最佳比例为3¨1;所得堆肥产品肥效指标和重金属含量均符合国家相应标准;同时可实现粪渣的零排放。
Aerobic static composting was used to treat and recycle night soil and green waste(leaves) in the Beijing Olympic Forest Park.Co-composting tests in pilot scale were analyzed to obtain the best night soil and leaves mixture ratio for various mixture mass ratios,temperatures,CO2 concentrations,germination indices,fertilizer efficiencies,and heavy metal contents.The results show that when a night soil of moisture content of 80% and green waste moisture content of 8% gives good composting results.The co-composting was realized at the night soil and green waste mixture mass ratios of 4∶1 and 3∶1,with the best mass ratio of 3∶1.The fertilizer efficiency and the heavy metal content of the co-composting product meet the national standard with zero effluents.
