It is high time to vigorously develop bio-natural gas

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.
