AI Technical Summary

Technical Problem

Existing technologies for treating livestock and poultry manure wastewater suffer from problems such as long treatment cycles, high costs, limited products, and failure to fully utilize resources. Traditional methods have failed to fully leverage the multiple functions of porous mineral materials.

Method used

This method utilizes microbial agents in conjunction with porous mineral materials to treat livestock and poultry manure under anaerobic conditions. Through the synergistic effect of probiotics and fermenting bacteria, organic matter is rapidly decomposed. Combined with the micronutrient dissolution function of porous mineral materials, a highly efficient biofilm interface effect and denitrification space are formed, achieving rapid composting and element dissolution. The product concentration is cyclically adsorbed and regulated.

Benefits of technology

It achieves full resource utilization of livestock and poultry manure, shortens reaction time to 3-7 days, reduces energy consumption and treatment costs, and produces high-value water-soluble fertilizer and slow-release organic fertilizer to meet different market demands.

Abstract

This invention relates to a method for treating livestock and poultry manure slurry using a combination of microbial agents and porous mineral materials, belonging to the field of agricultural waste resource utilization technology. The method involves reacting livestock and poultry manure slurry with a composite microbial agent and porous mineral materials under anaerobic conditions. The porous minerals provide a carrier, and the extracellular enzymes secreted by the microorganisms directly cleave the organic matter, bypassing the microbial succession stage of traditional composting, achieving rapid enzymatic decomposition in 3-7 days. The decomposed liquid, containing trace elements, can be directly diluted and used as a water-soluble fertilizer. The porous mineral materials involved in the reaction, after low-temperature drying, can be used as organic fertilizer additives or soil conditioners, achieving full resource utilization of the manure slurry. This invention avoids secondary fermentation and biogas production, has low energy consumption, and a short treatment cycle.
