This application discloses a trough fermentation system for lignite fermentation, including a fermentation trough and a heating device for heating the fermentation trough. A floor heating coil is installed at the bottom of the fermentation trough. The heating device supplies heat to the fermentation trough through the floor heating coil, providing different amounts of heat to the fermentation trough in the early, middle, and late stages of fermentation, respectively, so that the fermentation trough is in the first, second, and third stages. The gradient temperature control of this application can accurately meet the temperature requirements of different stages in the fermentation process, significantly improving fermentation efficiency, accelerating the fermentation process, significantly shortening the fermentation cycle, and reducing greenhouse gas emissions, thus offering environmental advantages.

This invention discloses a method for biotechnology-based conversion of livestock and poultry manure into animal feed, belonging to the field of agricultural waste resource utilization. The method includes: solid-liquid separation and crushing of livestock and poultry manure, adjusting the moisture content to 65%~75%; applying a pulsed electric field to treat the manure, resulting in a microbial cell breakage rate ≥70% and a cellulose crystallinity reduction ≥15%; adding a complex enzyme preparation composed of laccase, manganese peroxidase, xylanase, and lysozyme for enzymatic hydrolysis; after cooling, inoculating a mixed flora of thermophilic Bacillus stearothermophilus and Kluyveromyces martensii acclimated with sodium acetate and phenol; conducting a two-stage fermentation, with an aerobic stage followed by closed, static fermentation; and finally, low-temperature vacuum drying and pulverization to obtain feed protein powder. This invention, through the synergistic effect of pulsed electric field, complex enzyme, and acclimated microbial flora, achieves efficient, safe, and rapid feed utilization of livestock and poultry manure, with a total processing time ≤72 hours, a crude protein content of 28%~35%, and antibiotic residue ≤0.2 mg / kg.

The utility model relates to fertilizer fermentation technical field discloses a kind of fermentation mixing devices for microbial fertilizer production, including fermentation tank and upper plate, upper plate is supported and fixed in the upper side of fermentation tank, electric push rod is vertically installed on the surface of upper plate, the end of electric push rod extension is fixed with hollow frame, hollow frame surface is connected with the air inlet pipe that its inside is communicated, two rings of ring pipes are arranged in the outer ring of hollow frame, and ring pipe and ring pipe between and ring pipe and hollow frame between are connected fixed through connecting pipe, the bottom of ring pipe and connecting pipe is evenly provided with multiple gas outlets that are communicated with ring pipe and connecting pipe inside.
