It is high time to vigorously develop bio-natural gas

Fifth, it is necessary to establish a policy system to promote the sustainable development of biological gas. Over the years, China's biological gas development is slow, the root cause is that the support policy is not systematic, not grounded gas, resulting in difficult policy implementation, difficult to effect. Therefore, on the one hand, we should optimize and improve the existing policy system, abandon the reconstruction of light management thinking, supplement the short board of the industrial chain, and focus on subsidizing the terminal links and products, so as to stimulate the development of the entire industry. On the other hand, the breeding industry should focus on "promoting the utilization of livestock and poultry waste resources in the whole county in non-livestock counties" and standard farms (communities), truly implement the pollutant compensation treatment mechanism of "who pays for polluting" and "who treats who benefits" of livestock and poultry waste, strengthen the supervision of environmental protection law enforcement, and build a market-oriented treatment mechanism for livestock and poultry waste. At the same time, it should be clear that biogas and biological gas projects enjoy preferential policies for agricultural facility land and agricultural production electricity. In addition, it is necessary to scientifically plan demonstration projects according to local conditions, establish a complete industrial chain and benefit chain, form a number of biological gas development models suitable for China's northern and southern climates, which can be replicated and promoted, and strengthen the construction of rural energy service system to meet the needs of the development of biological gas industry in the new era.

Sixth, we must seek truth from facts and choose the development model of biological natural gas. China has a vast area and great climate difference between the north and the south, so the development model should be selected according to local conditions around urban gas, vehicle gas, township residents and farmers' gas supply. In terms of the scale of development, it should be large and small. In the promotion and sales of appropriate network is network, appropriate bottle is bottle; In the development mode, we should jump out of the rural energy limitations, adhere to the interaction between urban and rural areas, and the interaction between industry and agriculture, and take the city with the countryside and plan the development of biological natural gas with industrial thinking. Promote the sale of biological natural gas to urban gas pipe networks and vehicle gas, feed rural energy with high added value, and achieve a win-win situation between urban and rural areas.

Seven to smooth biogas residue, biogas liquid sales channels. To achieve high quality development of biological natural gas, it is a prerequisite to solve the export of biogas residue and biogas liquid market. Biogas residue and biogas slurry are high-quality organic fertilizers, but whether farmers accept them depends on the added value of agricultural products, otherwise it is better to use chemical fertilizers without increasing income. It is necessary to accelerate the adjustment of planting structure, increase the proportion of organic agricultural products, provide sales space for biogas residue and biogas liquid, improve brand awareness and added value of agricultural products, and promote farmers' income. The agricultural management department should effectively promote the transformation and upgrading of the aquaculture industry, reduce the amount of antibiotics in the aquaculture industry, and reduce the residue of antibiotics in the biogas slurry. In the cold winter in the north, it is necessary to solve the contradiction between perennial farming and seasonal planting, improve the processing and storage capacity of biogas residue and biogas liquid commercial fertilizer, and ensure the normal operation of biogas projects in winter.

Eighth, we should promote the high-quality development of biological natural gas with scientific and technological progress. We will carry out technological research on low-temperature fermentation in northern China, increase the gas production rate of tanks, and develop new processes, new materials, and new equipment for biogas projects, introduce and absorb advanced biogas fermentation technologies from abroad, improve relevant technical standards and norms, and promote new technologies and models such as "Internet of Things +", remote online monitoring, and intelligent regulation.
