- 摘要:
- 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18 d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。
- Abstract:
- Taking sludge,cattle mature,corn stalk as test materials,aerobic compost technology was used in this research,by adding cattle manure and corn stalk in sludge compost.In a reasonable range of C/N,the different proportions of materials were designed with four treatments which tested at the same time,to realize resource utilization of peri-urban waste.The results showed that the temperature,moisture and pH value of every treatment achieved desired results.The data of seed germination test showed that germination index of the treatment A and treatment B (sluge∶cattle mature∶corn stalk of 5∶(2~3)∶4)were both higher that 80% implied that the compost became maturity.The results in comparison showed that the optimum proportion of sewage sludge,cattle manure,and corn stalk was 5∶2∶4.The data demonstrated that the temperature of compost achieved above 55℃ fast and continued 18 days,the moisture was decreased 11.7%,total nitrogen was reduced 0.15%,organic matter content was decreased 28.3%,germination index was 82.1% and pH value was maintained at 6 to 9.Composting of cattle manure and sludge added straw not only realized realize resource utilization but also had more application prospects.
