Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, in particular to a method for preparing a coenzyme enzyme organic nutrient solution beneficial to crop growth. Background Art

[0002] The harmless treatment and resource utilization of the liquid portion of livestock and poultry manure is a global challenge for achieving a circular economy in modern agriculture. For many years, it has been the focus of research and development by numerous professional institutions. Key technologies include: 1. Physical treatment: 1. Screening most solids from liquid manure to reduce the subsequent processing load; 2. Ultraviolet disinfection. 2. Biological treatment: Utilizing microbial technology to decompose organic matter in liquid manure, kill harmful bacteria, and accelerate fermentation. 3. Chemical treatment: 1. Adding lime milk solution to improve the settling properties of liquid manure, causing colloidal substances to form flocculent sediments; 2. Adding a coagulant to aggregate and settle fine suspended solids and colloidal particles; 3. Adding chlorine dioxide to disinfect and kill pathogenic microorganisms.

[0003] Existing biotechnology methods for treating liquid manure typically involve adding fermentation-promoting microorganisms to a sedimentation tank or sealed container, either anaerobic or aerobic, to improve fermentation efficiency. The goal is to reduce treatment costs and more quickly meet national biogas standards for discharge or return to farmland. These methods suffer from significant instability: First, incomplete fermentation can lead to excessive levels of heavy metals, salt, COD, and conductivity in the manure liquid, which can cause secondary pollution when discharged or returned to farmland. Second, the long treatment cycle (approximately 90 days or longer) results in increased carbon and methane emissions. Third, resource utilization is low, making it difficult to generate economic benefits. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a method for preparing a coenzyme enzyme organic nutrient solution that is beneficial to crop growth.

[0005] In order to solve the above problems, the technical solution of the present invention is: a method for preparing a coenzyme enzyme organic nutrient solution beneficial to crop growth, comprising the following steps: S1. Perform preliminary solid-liquid separation on the livestock and poultry manure liquid, and store the filtrate in a storage tank; S2. The livestock and poultry manure liquid in the storage tank is disinfected by a submersible pump through an ultraviolet sterilizer; S3. The disinfected livestock and poultry manure liquid is transported to a mixing tank, and Bacillus Velez, molasses, protease, algae polysaccharide and plant protein are added to the mixing tank and stirred thoroughly; S4, transporting the liquid in the stirring tank to the fermentation tank through a delivery pump for full fermentation treatment; S5, performing fertilizer treatment on the fermented liquid to obtain a coenzyme enzyme organic nutrient solution; S6. Filter and can the coenzyme enzyme organic nutrient solution.

[0006] Furthermore, in the step S1, the livestock and poultry manure liquid is filtered through a 40-mesh drum filter.

[0007] Furthermore, the filter residue obtained by filtering with the drum filter is composted.

[0008] Furthermore, in step S3, molasses is a by-product of a sugar refinery.

[0009] Furthermore, in the step S4, the livestock and poultry manure liquid stays in the fermentation tank for 3-5 days, and is stirred and aerated every day.

[0010] Furthermore, a sign of sufficient fermentation treatment of the fecal liquid in the fermentation tank is that the pH value reaches below 4.

[0011] Furthermore, in the step S5, the contents of the main nutrients, such as nitrogen, phosphorus and potassium, in the fermentation liquid need to be tested before fertilizer is added.

[0012] The advantages of the present invention compared with the existing technology are: the present invention shortens the harmless treatment time of liquid manure and reduces the treatment cost, and the entire process is emission-free and more environmentally friendly. In addition to retaining the original nutrients of manure such as nitrogen, phosphorus, potassium, calcium, iron, zinc and other major, medium and trace elements, the treated liquid is also rich in various amino acids, proteins, organic matter, humic acid and other nutrients required for plant growth, thereby realizing high-value utilization of livestock and poultry manure.
