Description
技术领域technical field
本发明涉及一种沼气应用系统，尤其涉及沼气综合利用系统。The invention relates to a biogas application system, in particular to a biogas comprehensive utilization system.
背景技术Background technique
沼气是可再生的清洁能源，既可替代秸秆、薪柴等传统生物质能源，也可替代煤炭等商品能源，而且能源效率明显高于秸秆、薪柴、煤炭等。农村牲畜粪便臭气熏天，传染疾病，且看相不佳。更为严重的是，其中所含有机质进入水域后，会造成大量水体富营养化，导致蓝藻疯长，水质量恶化。牲畜粪便成为农村污染的主要因素。另外粪便经过沤肥，经过好氧发酵，这个过程中会产生大量有害细菌、病毒，这些农家肥很轻易地就渗透到地下水，地下水再与外流域的水体交流置换，污染便进入地表水。同时，农家肥也会通过雨水冲刷、清洗农具等途径，直接进入地表水，造成污染。Biogas is a renewable clean energy that can replace not only traditional biomass energy such as straw and firewood, but also commodity energy such as coal, and its energy efficiency is significantly higher than that of straw, firewood and coal. Livestock manure in rural areas is stinky, infectious, and unsightly. What's more serious is that after the organic matter contained in it enters the water area, it will cause a large amount of eutrophication in the water body, resulting in the growth of blue-green algae and the deterioration of water quality. Livestock manure has become the main factor of rural pollution. In addition, manure is retting and aerobic fermentation. During this process, a large number of harmful bacteria and viruses will be produced. These farmyard manures can easily penetrate into the groundwater, and the groundwater will exchange and replace with the water in the outer basin, and the pollution will enter the surface water. At the same time, farmyard manure will also directly enter surface water through rainwater washing and cleaning of farm tools, causing pollution.
