The Ministry of Agriculture Planning and Design Institute of Rural Energy Environmental Protection has relied on the “Eleventh Five-Year Plan for Science and Technology Support Program†to optimize the integration of “straw integrated two-phase anaerobic fermentation†technology. They have set up a demonstration project for centralized gas supply of 1,200 cubic meters of large-scale fermentors in Sidankou Village, Jinghai County, Tianjin. The gas production rate is 20% higher than that of general biogas fermentation tanks; the annual output of biogas is 540,000 cubic meters and can meet 1,000 households. Farmers use for food; one year can digest 2,000 tons of silage straw. The technology passed the expert appraisal not long ago. Experts believe that this technology solves the problem of straw biogas fermentation, broadens the sources of biogas fermentation raw materials, opens up new ways for comprehensive utilization of straw, highlights innovation, reaches the leading domestic level, and has broad application prospects.
In China, about 200 million tons of straw each year is not treated in a timely manner, causing air pollution and waste of resources. Straw contains a large amount of organic matter and can produce biogas through anaerobic fermentation. However, due to the high lignocellulose content and poor flowability of straw, biogas projects using straw as raw material have difficulties in feeding and discharging, unstable gas production, slow fermentation speed, and low efficiency. problem. The main innovation of the “straw integrated two-phase anaerobic fermentation technology†is firstly in the pretreatment technology—it is the silage technology introduced into animal husbandry during the pretreatment of straw fermentation, which not only solves the preservation of straw and Digestion problems can also promote the subsequent fermentation. In the feeding mode, this technology achieves the closed transportation of large-size materials by optimizing and designing the open pneumatic conveying equipment in the feed industry; “straw integrated two-phase anaerobic fermentation process The "anaerobic digestion reactor" structure of the technology is also an innovation point - it separates acid production and methane production in different regions in the same fermentor, so that the acid production and methanogenesis strains can achieve the best fermentation effect respectively. Enhance the complementarity and synergy between different strains and improve the efficiency of gas production. Then, the biogas slurry is returned to the aggregating tank and mixed with the feed to achieve multiple inoculation of the material and further improve the gas production efficiency. In addition, the liquid digestate produced by the process is recycled by the internal system, no biogas slurry is discharged, and the moisture content of the biogas residue is low. The fertilizer can be used without dehydration, effectively solving the problem of the transportation of a large amount of biogas residue after the gas production. problem.
