沼气能源建设（沼气提纯），一方面可以补充农村生产生活的能源需求;另一方面，可以减少工业生产中有机废水和生活垃圾对环境造成的危害。沼气发电综合利用环境保护与节能相结合的新技术。它利用工业、农业和城市生活中大量的有机废用物，以及氧气发酵产生的沼气来驱动沼气发电机组。同时，充分利用发电机组的余热生产沼气。综合热效率在80%以上，高于一般发电效率的30%-40%。经济效益显著。直接的优点是解决了用电问题，节约了用电成本。例如，一个一年饲养2000头以上种猪的养猪场，需要使用饲料粉碎机、搅拌机、冬季对仔猪的保温以及培养箱。过去一年里，平均每月的电力支出超过5000元。使用沼气发电意味着它可以节省大量的电力成本。

Biogas energy construction can supplement the energy demand of rural production and life on the one hand; On the other hand, it can reduce the harm to the environment caused by organic wastewater and domestic waste in industrial production. Comprehensive utilization of biogas power generation is a new technology combining environmental protection and energy saving. It uses a large number of organic wastes in industry, agriculture and urban life, as well as biogas produced by oxygen fermentation to drive biogas generator sets. At the same time, make full use of the waste heat of the generator set to produce biogas. The comprehensive thermal efficiency is more than 80%, which is higher than 30% - 40% of the general power generation efficiency. Remarkable economic benefits. The most direct advantage is that it solves the problem of power consumption and saves the cost of power consumption. For example, a pig farm that raises more than 2000 breeding pigs a year needs to use feed crushers, mixers, heat preservation of piglets in winter and incubators. In the past year, the average monthly electricity expenditure exceeded 5000 yuan. Using biogas to generate electricity means that it can save a lot of power costs.

其次，它有助于减少农场污染。对于养猪场来说，麻烦的问题是猪粪和污水处理。然而，沼气发电可以很好地解决这些污染物。来自养猪场的粪便和污水可以进入沼气池，由一根管道输入。沼气池排出的沼气液可用于清洁猪圈，实现循环养殖模式，降低污染风险。沼气发电还可以产生额外的经济效益。例如，投资30万元，容量500立方米的沼气池和50千瓦发电机，一年可生产沼气5.2万立方米，发电7.5万度，年产沼气渣和沼气浆4000吨，经济效益15万元。

Second, it helps reduce farm pollution. For pig farms, the most troublesome problems are pig manure and sewage treatment. However, biogas power generation can solve these pollutants well. Feces and sewage from pig farms can enter the biogas digester and be input by a pipe. The biogas liquid discharged from the biogas digester can be used to clean the pigsty, realize the circular breeding mode and reduce the pollution risk. Biogas power generation can also produce additional economic benefits. For example, with an investment of 300000 yuan, a biogas digester with a capacity of 500 cubic meters and a 50 kW generator can produce 52000 cubic meters of biogas a year, generate 75000 kwh of power, produce 4000 tons of biogas residue and biogas slurry a year, and achieve an economic benefit of 150000 yuan.
沼气提纯

沼液和沼渣中含有多种氨基酸、生长素、抗生素和多种微量元素，可作肥料利用、饲养利用、生物农药、培养料液等。沼液可作为有机肥料灌溉到农田中或者直接喷洒到植物叶面作叶面肥，既能增加作物产量、提高产品品质，又能增强作物的抗逆性;可用作饲料添加剂，使猪提前出栏、肉质提高，鸡产蛋率提高;可进入鱼塘促进浮游生物的生长，是鱼的良好饵料，使鱼的产量提高、抗病性增强;可用于浸种，提高种子的出芽率和以后的生长能力;可作为无毒、无残留的农药来防治农业病虫害。

Biogas slurry and biogas residue contain a variety of amino acids, auxin, antibiotics and trace elements, which can be used as fertilizer, feeding, biological pesticide, culture material, etc. Biogas slurry can be used as organic fertilizer to irrigate farmland or directly sprayed on plant leaves as leaf fertilizer, which can not only increase crop yield and improve product quality, but also enhance crop stress resistance; It can be used as feed additive to make pigs go out of the market in advance, improve meat quality and improve chicken egg laying rate; It can enter the fish pond to promote the growth of plankton. It is a good bait for fish, which improves the yield and disease resistance of fish; It can be used for soaking seeds to improve the germination rate and future growth ability of seeds; It can be used as a non-toxic and residue free pesticide to control agricultural diseases and pests.
