| 摘 要： | 在寒冷的冬季，沼气的使用中存在产气率低、使用率低、使用时间短、沼气使用综合效益差等问题。浙江省诸暨市银辉生态养殖场的沼气工程利用太阳能加热，巧妙地解决了寒冷地区冬季沼气生产的问题。采用跟踪监测和对比参照的方法对该沼气工程进行了监测。结果表明：在冬季，该系统厌氧发酵池的池温最高温度为22．8℃，最低温度为12．7℃，产气率在75m^3.d^-1以上，可产生经济效益23万元·a^-1，可以切实提高沼气工程的温度及产气率，并对沼气工程的经济、生态、社会效益进行了评估，值得大规模的推广应用。

| Abstract: | During cold winters, application of methane gas production has had problems, such as a low use- rate, a short use-time, and poor comprehensive benefits. To introduce the specific and assessed economic, eco- logical, and social benefits of biogas projects, solar energy was used for heating to solve the cold winter biogas production problems at the Zhuji City Silverlit Ecological Farms Biogas Project. Results from the project showed a maximum pool temperature for the anaerobic femlentation tank of 22.8 ℃, a minimum temperature of 12.7 ℃, a gas production rate that remained 75 m^3.d^-1 or more, and an annual income of 230 000 Yuan. Thus, it would be worthwhile to large-scale application of a solar collector system. |
