根据武汉市东西湖区养殖场实际情况,规划设计了一整套以沼气生产为纽带的循环经济工程技术模式,分析评估了养殖业固废处理循环经济实施的经济效益和环境社会效益.该模式以"暗河式大型联合沼气生产技术"为基础,将畜禽废弃物经过一系列的生物厌氧发酵产生沼气;沼渣、沼液结合好氧堆肥保温设施生产优质有机肥料;以现代化污水处理系统和人工湿地生态化处理沼液和养殖场废水,达到中水回用的标准;湿地种植饲料植物.在彻底消除畜禽养殖废弃物产生的环境污染的同时,实现养殖场循环经济生产模式的正常运作与发展.研究设计结果对其它地区实施养殖业固废处理循环经济模式具有一定借鉴意义. 相似文献

To date, there are about 49 biogas plants in South Korea that are generally recognized as economically and technically unsuccessful due to lack of knowhow, deficient technologies and policies. There is a need to analyze the status of biogas technology and policy in South Korea from the point of view of an external biogas expert, since biogas technology in South Korea has not yet been analyzed by foreign biogas experts so far. For analyzing site investigation, literature research and interviews are performed. It was found that there are several lacks of conceptual design of biogas technology, such as plant dimension, energy balance, operation knowhow. Technical and financial support for the development of biogas technology was insufficient so far. There are some policies to support biogas technologies, however financial support from different ministries seemed not to have been used efficiently. Some policies are planned excessively so that they cannot be realized on time. Based on the general policy called “Green Growth”, the Korean government plans to establish a biogas market in South Korea in order to recover energy from organic waste. For this purpose, R&D efforts should be intensified for consulting and education in national and international networks for the transfer of knowhow and technologies. Definition of the existing restrictions on the development of biogas technology is required. By developing a biogas roadmap, the creation of a biogas market could be promoted efficiently in South Korea. 相似文献

基于外部性收益的畜禽养殖场沼气工程补贴模式分析 总被引:1,自引:0,他引:1
以我国北方某沼气工程为例,按照业主自筹全部资金、2009年国家建设补贴标准和工程实际投资3种建设投资方式,对其现有经济性进行了分析,并提出了以外部性收益为依据对沼气工程进行补贴的两种模式。结果表明,外部性收益与沼气工程运行效果和沼气产量有直接关系,依据外部性收益对沼气工程进行补贴,可以显著提高沼气工程的经济效益,推动规模化养殖场沼气工程正常运行和发展。综合沼气工程投资者和社会利益考虑,业主自筹全部建设资金,按照工程实际运行的外部性收益给予补贴,既可保障工程的正常运营,又符合整体经济性。 相似文献

城市有机垃圾车库式干发酵技术 总被引:1,自引:0,他引:1
城市有机垃圾处理和资源再生利用已成为我国建设资源节约型和环境友好型社会中迫切需要解决的问题。欧洲国家中以德国为代表的车库式干发酵技术(Garage-type dry anaerobic digestion)已经成熟,可进行规模化的沼气生产。文章着重介绍了车库式干发酵沼气工程的技术要点,并以德国Loock TNS工艺和黑龙江宾县车库式干发酵项目为例,介绍了有机垃圾车库式干发酵喷淋回流、系统密封等关键技术,以期为我国车库式干发酵工程的工艺设计提供参考。 相似文献

As a renewable energy, biogas is not only an important part of the development of rural new energy, but also an important aspect of sustainable development in China. The development process and present status of household biogas, specifically the opportunities and constraints of household biogas in rural China, are discussed in this paper. Only about 19% of the biogas potential has been utilized in rural China. There are several opportunities for household biogas development in rural China, including the problem of rural household energy consumption, the availability of biogas fermentation materials, national financial subsidies, legal and international clean development mechanisms. Also, more research needs to be done in straw fermentation and cold fermentation technology. Training should be conducted to raise the level of biogas customers in comprehensive biogas utilization. Measures should be taken to improve the follow-up services and management of biogas plants. The information presented in this paper will be helpful not only to the sustainable development of household biogas in rural China, but also to the development of biogas in similar countries around the world. 相似文献
