以污泥、牛粪、玉米秸秆为试材,采用好氧堆肥技术,在污泥堆肥中添加牛粪和玉米秸秆等物料,在合理的C/N范围内,对不同配比的物料作为4个处理进行试验,以实现对城市周边废弃物资源化利用。结果表明:各处理的温度、含水量、pH值均达到了较理想的效果;种子萌发试验表明,A、B处理(污泥∶牛粪∶玉米秸秆为5∶(2~3)∶4)的种子发芽率大于80%,达到腐熟效果;最佳配比方式污泥∶牛粪∶玉米秸秆为5∶2∶4。其温度快速升高至55℃以上并持续18d之多,含水量降低11.7%,总氮降低0.15%,有机质含量下降28.3%,种子发芽率为82.1%,pH值保持在6~9;污泥、牛粪加入秸秆进行堆肥,不仅实现了废弃物的资源化,而且有较好的应用前景。
With sludge, cow dung, corn stalks as test materials, using aerobic composting technology, adding sludge and corn stalks and other materials in the sludge compost, in a reasonable C / N range, the proportion of different materials as 4 A trial of treatment to achieve the city's waste around the resource utilization. The results showed that the temperature, the water content and the pH value of the treatments all achieved the ideal results. The seed germination tests showed that the treatments A and B (sludge: cow dung: corn stalk 5: 2 ~ 3) Of the seeds germination rate of more than 80%, to achieve the maturity effect; the best ratio of sludge: cow dung: corn stalks 5: 2: 4. The temperature increased rapidly above 55 ℃ for 18d, the water content decreased by 11.7%, the total nitrogen decreased by 0.15%, the organic matter content decreased by 28.3%, the seed germination rate was 82.1% and the pH value kept at 6 ~ 9. , Cow dung added straw compost, not only to achieve the recycling of waste, but also has a good prospect of application.
