| 中文摘要 |
| 堆体温度受各种理化参数的影响,也与环境温度有密切关系.试验表明,环境温度对污泥堆肥的起始升温影响不大,5.8℃以上的环境温度污泥堆肥均可以顺利升温;但是达到高温期的污泥堆肥,因为易降解有机质含量的减少,使其产热量减少.环境温度的剧烈变化会影响堆肥过程的进行,环境温度降低至5℃以下时,本试验堆量的污泥堆肥已难以进行,环境温度在10℃以上时,经过通气等的调节堆肥可以进行。 |
| 英文摘要 |
| Temperature is reflection of composting microorganism activity,which is an important factor to affect microorganism and composting. The composting temperature can be affected by several of physical and chemical parameters,and also can be affected by air temperature. In this experiment,the surrounding temperature had a little affect on the initial composting temperature when the surrounding temperature was above 5.8℃,the piles temperature can rise smoothly But when the pile temperature reached the stage of high temperature and last for few days and the decrease of surrounding temperature was below 5℃,the composting failed. |
