Problems solved by technology

[0004] The research on the purification method of biogas slurry mostly follows the urban sewage treatment method, using physical, chemical and biological methods, such as natural biological treatment methods such as biological pond method and artificial wetland, and industrialized treatment models using reactors such as MBR, SBR and reverse osmosis. However, due to the characteristics of high operating costs and difficult operation techniques, these methods are difficult to promote in farmers, and the above methods are not very effective in removing N and P in water. Therefore, after simple aeration treatment of biogas slurry Direct discharge is still the main treatment method at present
There are also some biogas slurry used for farmland irrigation, biogas slurry seed soaking, foliar spraying, soilless cultivation, etc., but due to transportation costs and application safety issues, the use of biogas slurry is very small and cannot be used for large-scale aquaculture. A large amount of biogas slurry produced by anaerobic fermentation, so direct discharge is still the main treatment method of biogas slurry

Abstract

The invention provides an improved biogas slurry ecological treatment and cultivation system. The improved biogas slurry ecological treatment and cultivation system comprises a solid-liquid separationpond, a decomposition treatment pond, an aeration treatment pond, a PH (Potential of Hydrogen) regulating pond, an algae culture pond and an animal culture pond which are arranged according to a sequence of a treatment technology, wherein the solid-liquid separation pond, the decomposition treatment pond, the aeration treatment pond, the PH regulating pond, the algae culture pond and the animal culture pond are in end-to-end serial connection in sequence; the solid-liquid separation pond is used for carrying out precipitation treatment and disinfection treatment; the decomposition treatment pond is used for anaerobic and aerobic catabolism treatment; the aeration treatment pond is used for carrying out aeration treatment on biogas slurry; the PH regulating pond is used for supplementing and regulating the concentration, the PH and the nutritive salt component of the biogas slurry; algae are bred in the algae culture pond, nutrients can be supplied to the algae by utilizing the biogasslurry and biogas, and the biogas slurry and the biogas can be purified by the algae; multiple aquatic products are bred in the animal culture pond in an isolation way, and main feed is provided by the algae. According to the improved biogas slurry ecological treatment and cultivation system provided by the invention, circulation ecological breeding industry can be formed, and the environment is improved.

Description

technical field [0001] The invention belongs to the technical field of biogas slurry treatment, and relates to biogas slurry purification cultivation, in particular to a biogas slurry ecological treatment cultivation system and an operation method thereof. Background technique [0002] Biogas slurry, also known as "anaerobic fermentation liquid", is a water-soluble by-product remaining after anaerobic fermentation of organic matter such as animal manure and straw. With the adjustment of the agricultural industry structure and the construction of new countryside, the intensive livestock and poultry breeding industry has developed rapidly. As the product of biogas anaerobic fermentation, these waste liquids are used as agricultural fertilizers or directly discharged, and little consideration is given to whether the discharge meets the standards or not. Agricultural safety. In fact, after anaerobic digestion, the biogas slurry still contains a large amount of nitrogen, phospho...
