Microorganism solid leaven and preparing method thereof

Abstract

The present invention relates to one kind of microbial solid fermenting agent and its preparing process. Microbial seeds are cultured compositely to obtain the microbial seed combination for treating waste as resource. The fermentation process is anaerobic process, and has the advantages of less consumption of nutritive components, short period, low power consumption and high conversion rate. During the fermentation, microbes and its produced physiological metabolic matters can kill various pathogenic bacteria, decompose and convert various organic pollutants and produce various fermented products, such as organic fertilizer obtained via converting animal excrement, protein feed obtained via converting straw, fermented protein feed obtained via converting different leftover, etc.

Description

Technical field: [0001] The invention relates to a microbial solid fermentation agent and a production method thereof, which can be used for waste resource treatment and sewage treatment such as livestock and poultry manure, crop stalks, compost fermentation, swill, food processing waste, etc., belonging to waste harmless treatment and resources utilization technology field. Background technique: [0002] At present, the aquaculture industry is becoming more and more large-scale, and the pollution caused by livestock and poultry manure has become a major pollution source in my country; at the same time, a large amount of crop straws are basically incinerated because they cannot be used, causing serious air pollution; Directly being used for feeding pigs directly endangers the vital interests of consumers in general. At present, domestic and foreign have begun the research on the technology of microbial treatment of animal manure, and the published patent, the notification nu...

Problems solved by technology

[0002] At present, the aquaculture industry is becoming more and more large-scale, and the pollution caused by livestock and poultry manure has become a major pollution source in my country; at the same time, a large amount of crop straws are basically incinerated because they cannot be used, causing serious air pollution; Directly used to feed pigs, directly endangering the vital interests of consumers

At present, domestic and foreign have begun the research on the technology of microbial treatment of animal manure, and the published patent, the notification number is CN94111570, discloses a kind of high-temperature mixing with multiple microorganisms, and the method for rapidly fermenting livestock and poultry manure to produce bio-organic fertilizer. The patent adopts anaerobic fermentation and aerobic fermentation in parallel, and the fermentation period is 15 days. The high temperature generated during the fermentation process is easy to consume nutrients, and the fermentation period is long
