With the increasing demand for food and the continuous consumption of natural resources, the cultivated land area available for human beings is continuously reduced, and the fertilizer resources and raw materials capable of being exploited and synthesized are continuously reduced, so that the human beings need to produce more crops or grain products on a unit area of cultivated land. In the existing agricultural production, in order to improve the yield of crops, chemical fertilizers are adopted to cultivate the crops in large quantity; however, the dependence of crops on chemical fertilizers is increased year by year due to the long-term use of a large amount of chemical fertilizers, the land fertilizers are less and less, the actual utilization rate is only 35% when the crops are irrigated by using the chemical fertilizers, the rest of the chemical fertilizers are volatilized into the atmosphere or flow into rivers and lakes along with water flow, so that the environmental problems of soil hardening, atmosphere pollution, water source pollution and the like are serious day by day, and the chemical fertilizers pose serious threats to the health and survival of human beings and other organisms.
In China, furfural production and export are about 30 million tons in the annual output of large countries, and 12-15 t of furfural residues are discharged when 1 ton of furfural is produced, so that the amount of the waste residues discharged every year reaches millions of tons; the carbide slag is waste slag which is obtained by hydrolyzing carbide and takes calcium hydroxide as a main component, more than 300 kg of acetylene gas can be generated by adding water into 1t of carbide, and 10t of industrial waste liquid with the solid content of about 12 percent is generated at the same time, and is commonly called carbide slag slurry. When humic acid is extracted from weathered coal and lignite to be used as fine potassium humate, potassium fulvate and other products, a large amount of centrifugal waste residue is discharged, and 1T of coal approximately corresponds to 0.6-0.8T of centrifugal waste residue with the water content of 50-70%. The accumulation of the industrial waste can occupy a large amount of space, so that the serious environmental pollution problem is caused, a large amount of sites are occupied, and meanwhile, the subsequent treatment needs huge cost.
