Problems solved by technology
[0002] Large-scale pig breeding is an important way for farmers to increase their income in agricultural production, but at the same time, a large amount of fecal and urine biomass resources are produced annually. This resource has not been developed in time and has become a pollutant, resulting in the following four major issues: Problems: 1) The biogas slurry is mixed with irrigation water, which seriously reduces the output of young rice seedlings; 2) The biogas slurry seriously pollutes the environment; 3) The biogas seriously pollutes the atmosphere; 4) The risk of pig disease increases, which seriously affects the large-scale breeding of pigs

Embodiment Construction
[0017] See figure 2 , Is a schematic diagram of the system dynamics third-order matter delay function model, using the system dynamics n-order matter delay function theory of Professor Jay W. Forrester of the United States, using the system dynamics third-order matter delay function model, and its third-order matter delay function function is as follows :
[0018] The substance flows into the first-stage delayed flow position LEV1(t) at the inflow rate IN(t), and then the substance flows into the first-stage delayed flow position LEV1(t) at the flow rate R1(t)=LEV1(t) / (DEL / 3) The second-level delayed flow position LEV2(t), and then the substance flows from the second-level delayed flow position LEV2(t) into the third-level delayed flow position LEV3(t) at the flow rate R2(t)=LEV2(t) / (DEL / 3) ), and finally the substance flows out at the outflow rate OUT(t)=LEV3(t) / (DEL / 3) to realize the third-order delay function of the substance, where DEL is the total delay time.

The invention relates to a method for biogas liquid multistage delay filter, aerobic storage and multi-organism chain circulation. The method comprises four biogas liquid natural ecological treatment projects: biogas liquid three-stage delay filter, biogas liquid natural current aerobic, biogas liquid shunting three-stage storage abbreviated as a biogas liquid delay project, and a five biological chain circulation project. The two parts mutually promote to form a positive feedback circulatory system; and biogas liquid shunting, delay filter, oxygenation storage and five culturing biological chains are comprehensively utilized to form a high-efficiency agricultural biomass energy industrial system. The method realizes ecological economic benefit, scale cultivation, income growth of peasants, and increasing yield of rice annually. The biogas liquid is utilized for fertilizing and planting vegetable in winter fallow field to produce non-polluted green food. The biogas liquid is used for fertilizing and planting biomass feed of sweet potato to realize economic circulation. The biogas liquid is used for planting fish feed to produce a high-quality non-polluted green fish product. In time and quantity selection, the biogas liquid is utilized for fertilizing and planting fruit trees to achieve the aim of beautiful environment and scale cultivation.
Description
Technical field [0001] The invention relates to the technical field of ecological environmental protection and comprehensive utilization of ecological breeding, in particular to the engineering technology of natural ecological treatment of biogas slurry. Background technique [0002] Large-scale pig breeding is an important way for farmers to increase income in agricultural production, but at the same time, a large amount of manure and urine biomass energy resources are produced annually. This resource has not been developed in time and has become a pollutant, resulting in the following four major issues: Problems: 1) The biogas slurry is mixed with irrigation water, and the production of young rice seedlings is severely reduced; 2) The biogas slurry seriously pollutes the environment; 3) The biogas seriously pollutes the atmosphere; 4) The risk of pig disease increases, which seriously affects the large-scale breeding of pigs. After 2002, my country's large-scale pig farming shi...
