两种有机添加物与低有机质污水污泥的堆肥研究

目的]为低有机质含量污泥的处理提供方法。方法]以重庆地区低有机质含量的污水污泥为对象,选择园林有机废弃物和蘑菇渣2种外源添加物,在小试试验的规模上,研究2种有机添加物对污泥堆肥温度和理化指标的影响,并研究通气和未通气状态下堆体内氧气浓度的变化。结果]蘑菇渣和园林有机废弃物均可作为有机质含量偏低的污泥堆肥合适的调理剂,其中园林有机废弃物作调理剂发酵起爆速度快,堆体温度较高,发酵效果较好。结论]低有机质含量污泥的堆肥需要添加有机物料调理剂以促进堆肥的进行。

Study on Composting of Two Organic Amendments and Low Organic Sewage Sludge

Objective] The research aimed to provide the method of the low organic sewage sludge treatment.Method]Low organic sewage sludge was used as a resource,and the organic garden waster and spent mushroom compost were used as adding additives.Small test was conducted to study the effects of the sewage sludge compost on the two additives and the oxygen concentration variation in composting process.Result]The two additives were suitable for composting the low organic sewage sludge.The temperature rose rapidly in the composting process,and the effect of the fermentation was better.Conclusion]Composting of the low organic sewage sludge need to be added the organic amendments.
