Study On The Use Of Biogas In Rural Areas In Weichang County Of Hebei Province

With the construction of "production developing, life improving, local custom civilizing, village constructing, democratic management" of the new socialist countryside, in order to improve the people's living standards and farmer income, our country has strengthened the support strength to raising livestock and poultry.As a result of the increasing number, the rural environment was polluted increasingly, under the new rural development situation, to make the rural energy recycling, to develop ecological agriculture, one of the most effective ways is accelerating rural methane construction. Every year the government arranges 1 billion yuan treasury funds for rural methane construction. With the growing of raising livestock and poultry,farming communities, breeding of cultivating, cultivation enterprise, ten cubic meters of methane has gradually not satisfied and fully processed these livestock waste. In the process of development, many problems were exposed and affected the biogas digester construction pace and comprehensive use efficiency..By analyzing and comparing raising the livestock status, the pollution status and methane construction, the investigation of the present situation of domestic biogas with large and medium-sized biogas economic, social and comprehensive in WeiChang,the article is concluded that the new situation biogas development direction.This article mainly includes five parts.The first part: successively discuss the research background, research purpose and meaning, domestic and foreign literature review, research methods and technology way. Part two:the raising livestock status and pollution situation in WeiChang. As the paddock animal husbandry and large county of construction, in rural and urban edges, livestock pollution is becoming more and more serious, and see the pollution situation in WeiChang.Part 3:WeiChang county methane construction. The paddock of methane construction situation, most of which are housekeeping methane.From 2003 to 2009 WeiChang county constructed 14644 housekeeping methane pool with 10 cubic meters each, the country has already invested 4719 million yuan in total.Part four:the analysis of domestic biogas, partnerships methane, large and medium-sized biogas economic and social benefit. Analyze the economic investment of ten cubic meters housekeeping and 1000 cubic meters methane pool, at the same time find what the proportion of investment and self-raised is, and how much economic and social benefits a pool can give, the conclusion is that large and medium-sized biogas digester is more suitable for WeiChang. The fifth part:large and medium-sized biogas promotion space. In WeiChang how many village and towns are suitable to construct partnerships, large and medium-sized methane? Why partnerships and medium-sized methane construction speed is not fast, under what situation, the construction of breeders enthusiasm can be improved. By contrast, the conclusion to solve pollution caused by increasing livestock and poultry, compensate for domestic biogas deficiencies is to build partnerships and medium-sized methane.In 2010 WeiChang is defined as "green energy demonstration" to support the digester construction of annual gas production of 30 million cubic meters.WeiChang should make full use of this opportunity, concentrating on constructing more methane and large and medium-sized partnerships methane.Use various propaganda means to improve farmers' environmental awareness and improve their comprehensive utilization of methane, raise their awareness of the digester increase economic income consciousness, and gradually improve digester pool building technology and follow-up service system.
