Before the ban on burning crop straw was implemented, "burning it" was the most common scene of summer harvest and autumn harvest in rural areas.
Funan at that time was no exception. Funan County, as a traditional agricultural county, governs 28 townships with a population of 1.72 million and a cultivated land of 1.62 million mu. It is a well-known grain-producing county, a breeding county and a forest product processing county in China, and it is also a national key poverty alleviation and development county and the only agricultural (forestry) circular economy demonstration pilot county in China. Funan County produces about 6.5438+0.4 million tons of crop straw and 2 million tons of livestock manure every year, covering a large area and involving thousands of households. How to store, process and transform "a chess game" is a major event before the party Committee and government.
In recent years, Funan County has successively built three standardized storage centers 13, 84 enterprise straw storage stations, 320 village-level straw storage points, built three centralized treatment centers for livestock and poultry manure, and reformed the pollution control and utilization facilities of farms 13 1 one. In this way, the "last mile" of straw "leaving the ground and entering the station", "processing and entering the factory" and "livestock manure storage" was opened.
However, the resource utilization of agricultural waste is a professional and systematic work, which can no longer be promoted by the government as the main body in the past. "Doing things with market logic, doing things with capital power and doing things with platform thinking" has become the choice of Funan County.
Soon, Shanghai Linhai Ecological Technology Company, which focuses on the multi-dimensional controllable bio-natural gas technology system, entered Funan's field of vision. Relying on the scientific and technological support of Tongji University, the full-cycle treatment of agricultural wastes in Funan County has been implemented, and many development problems faced by agriculture and rural areas and the pollution of livestock and poultry wastes are expected to be solved.
On 20 16, Funan county government held docking talks with Shanghai Linhai Ecological Technology Company and signed a framework agreement. In 20 17, the PPP project of agricultural waste biogas and biogas development and utilization in Funan County was formally established, becoming the only PPP project approved by the Ministry of Finance in China. The project bidding was completed on 20 18. In June, the first three township projects of Wang Long, Miaoji and Gongqiao started construction. In 2020, the three stations of Wang Long, Gongqiao and Miaoji and the emergency peak-shaving center station of the project will be built one after another, and the natural gas pipeline will be laid 87 kilometers ahead of schedule to realize the "four stations through". In June 2020165438+1October, the gas pipeline network in the region was connected. The four stations consume 1.200 tons of agricultural organic waste every day, and generate 40,000 cubic meters of biological natural gas. 40,000 households and more than 200 enterprises and institutions in the county have used bio-natural gas, and nearly 65,438+10,000 mu of farmland have used Linhai organic fertilizer.
