Background
Vegetables are necessary for daily life. From the 'vegetable basket' proposed by the department of agriculture in 1998, central and local meat, egg, milk, aquatic product and vegetable production bases, improved variety breeding, feed processing and other service systems are established nationwide to ensure that residents eat fresh vegetables all the year round. The vegetable basket products are continuously and rapidly increased, and the situation of long-term shortage of subsidiary food supply in China is fundamentally changed. The vegetable basket project is surrounded in various places, such as Shandong, Gansu, Yunnan and the like, the supporting strength is increased, the standardization, the facility and the large-scale rapid promotion of the vegetable industry are realized, and the nationwide vegetable planting base is formed. Meanwhile, the matched refrigeration and logistics industry is developed correspondingly.
From vegetable planting bases to supermarket clean vegetables to come into the market, a large amount of defective vegetables and roots, stems, leaves and the like generated during refrigeration and clean vegetable processing become organic wastes, commonly called tail vegetables. According to statistics, the amount of the tail vegetables accounts for about 30-40% of the vegetable yield, and the effective utilization rate is low due to large yield, high water content (the average water content can reach about 95%), low effective components and lack of effective technologies. The soil is poured and buried at will, and after the soil is piled up, rotten and deteriorated, the air, the soil, the river and the underground water are polluted, the landfill site is also overloaded, a large number of mosquitoes and flies are bred, and the living environment and the body health of urban and rural residents are adversely affected. Therefore, the research on the effective utilization of the waste vegetables has important significance for relieving the pollution problem of the waste vegetables.
At present, the process of preparing the biogas by anaerobic fermentation is commonly adopted in the aspect of waste vegetable treatment. The main process comprises pretreatment, anaerobic fermentation and biochemical treatment of biogas slurry of the tailed vegetables. The anaerobic technology is complex to operate and has high technical requirements; meanwhile, the water content of the tailed vegetables is high (the average water content can reach about 95 percent), the effective dry matter is less, the unit biogas production amount is low, and meanwhile, the water content is high, the content of the contained nutrient substances is low, the biogas slurry amount is large (all seasons are produced), and sufficient soil digestion is difficult to achieve. Chinese patent CN 110272923A discloses a method and a system for recycling waste of waste tailstocks, the method comprises cleaning, removing impurities, sorting, pulping, blending materials, hydrolyzing and acidifying, anaerobic methane production and product recycling, wherein the product recycling is to reflux part of biogas slurry to a blending tank and reflux part of biogas slurry to a cstr anaerobic fermentation tank so as to improve the yield of biogas, but even after the product recycling, 50% of biogas slurry is still waiting for further treatment. Therefore, certain projects can only adopt a biochemical mode to treat the biogas slurry as 'wastewater', so that the loss of organic matters, N, P and K nutrients is caused, and meanwhile, the biochemical mode is influenced by the climatic environment and the quality of inlet water, the quality of the treated water is large in fluctuation and unstable, and secondary pollution is caused after the treated water is discharged.
