摘要
对甘蔗渣与牛粪,鸡粪和尿液等不同含氮物质混合堆肥过程进行研究,同时与分别添加城市污水处理中的活性污泥组进行对比,研究其对腐熟度的影响。结果表明:甘蔗渣与不同含氮的物质牛粪、鸡粪和尿液等进行混合堆肥均可以满足堆肥腐熟度的标准要求;堆体添加城市活性污泥可以在一定程度上促进腐熟,综合其对堆体温度、含水率、pH值、有机质变化以及发芽率等参数的影响、可以使堆肥时间平均减少5～7 d。
The objective of this experiment is studying the mixed composting process about bagasse and different nitrogen sources, such as cow dung, chicken manure and urine. Moreover, the experiment research the influence of activated sludge from city sewage treatment to maturity. The results show that the mixed compost of bagasse and different nitrogen source, including cow dung, chicken manure and urine, can satisfy the standard requirements of the composted maturity; To a certain extent, adding the activated sludge into the compost pile body can promote maturity and shorten composting time. Comprehensive considerations of the effects of various parameters on change of temperature, moisture content, pH, organic matter content and seed germination rate of in each compost process, it can make compost reduce the average time of 5-7 days.
