| Rural "clean energy" development, effectively reduce the comprehensive environmental cost |
Rural "clean energy" development of a comprehensive management contribute to the advancement of human and animal excreta, crop straw and other life, production waste and utilization, can effectively reduce the long-term cost of rural comprehensive environmental governance. To improve the economic benefit of agricultural production. The current agricultural production faced production costs, rising energy prices, production pressure, the development of rural marsh gas and other clean energy can effectively save gas, electricity and other energy expenditure; save pesticide and fertilizer production input; improve plant yield and quality, so as to alleviate the pressure on production costs, improve the economic benefit of agricultural production. Improving the using efficiency of land resources. On the current situation of agricultural production, rural labor force and a large number of the workers, "to benefit" from the land situation has basically ceased to exist, the land provides only basic means of subsistence farmers, therefore, a large number of land use efficiency is very low. Rural biogas energy development, must be based on large farms, agricultural park as the basis, and large farms, agricultural park scale production, improve the intensive use of land, improve land use efficiency. Besides the above points, large areas of the countryside to use clean energy to replace non renewable energy sources, to ease the pressure on China's energy, and its role is self-evident.
At the present stage is initiated by the scale of production, biogas energy therefore, to the development of biogas energy in the final analysis is to solve the pipeline gas collection, raw material conveying, technical support and other three major problems. There are two major difficult problems in the development of clean energy in rural areas: one is how to guarantee for supporting rural settlements to provide a stable supply of gas. This requires the collection of good raw material for biogas production work, so as to provide adequate protection of raw materials. Raw materials for the production of biogas mainly comes from rural residential and farming households of people and livestock manure and crop straw, according to the data show, 1 people living needs of biogas, based on the use of crop straw as fermentation materials, also need to have 1.5 pig manure produced pit entry fermentation can satisfy, therefore, such the consumption of raw materials for breeding in undeveloped rural is a very big problem, in fact, can use the high pressure fan to solve the problem of shortage of raw materials, the use of high pressure fan in the fermentation process can speed up the fermentation, the methane is greatly increased, thereby saving energy and material consumption, energy saving and environmental protection is a good helper.
