| 摘 要： | 以户用沼气池(8 m3)为研究对象,监测了一个发酵周期(发酵过程持续90 d)中沼气发酵料液内的指标变化,结果表明:随环境温度的变化,料液温度有所变化,但整体变化不大;从发酵初期到中期阶段,COD值逐渐增大,在发酵的第40~60天内变化平稳,此时产气量最大,发酵后期又逐渐变小;在发酵进行40 d时,料液内营养指标达到峰值,此时沼液肥效最佳。

| Abstract: | The change of index of fermented liquid in the fermented course during 90 days in the family-used biogas system was studied.The results showed that the temperature of the fermented liquid changed within the specific limit with the environmental temperature,but did not change much wholly;COD value changed obviously.While the fermenting course entered the 40th day,the nutrition indexes(organic matter,total nitrogen,total phosphorus and total potassium) reached one peak value on the whole,which meant that it was the best fertile effect of the fermented liquid at this moment. |
