Environment-friendly organic and inorganic fertilizer prepared with molasses alcohol waste mash used as raw material

Abstract

The invention discloses an environment-friendly organic and inorganic fertilizer prepared with molasses alcohol waste mash used as a raw material. High-temperature condensed bacilli are inoculated in just-discharged high-temperature molasses alcohol waste mash for fermentation, a metal complexing agent is added, then the molasses alcohol waste mash is kept to be evaporated at the high temperature for a period; the molasses alcohol waste mash is led into an anaerobic fermentation pool for anaerobic fermentation after being naturally cooled; then aerobic bacteria are added into the molasses alcohol waste mash, the mixture is mixed with organic filler and an inorganic fertilizer in a certain proportion for fermentation for 12-36 hours, the fermented molasses alcohol waste mash is subjected to degumming treatment and slurry-spraying granulation, then beneficial bacteria are added, and a finished product is obtained. According to the environment-friendly organic and inorganic fertilizer, other bacteria are removed through the high temperature, the metal complexing agent is added to remove heavy metals, bacterium fermentation effects at all phases are improved, the finished product has no obvious stink, the added organic filler is rich in inorganic nutrients and microelements such as N, P, K and the like, the production cost is saved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer made from molasses alcohol waste mash as a raw material. Background technique [0002] In recent years, the technological innovation and development of Guangxi sugar enterprises have gradually formed an industrial chain of "sugar cane → organic sugar → molasses → alcohol → molasses alcohol waste mash → production of fertilizers". In this industry chain, the problem of environmental pollution caused by the alcoholic fermentation liquid produced by the sugar industry is becoming more and more obvious. The alcoholic fermentation liquid produced by Guangxi sugar enterprises has reached more than 3.5 million tons in 2012, and it needs to be taken out every year. More than 500 million yuan of funds will be used for the harmless treatment of alcohol fermentation broth. Due to the high protein content of alcoholic fermentation broth, it has high chemic...

Problems solved by technology

Therefore, how to harmlessly treat and effectively utilize the alcohol fermentation liquid is the most critical part to break the bottleneck of the development of Guangxi's sugar industry and release the potential of Guangxi's sugar industry. Amino acid, yeast, etc. are important ways for the comprehensive utilization of sugarcane, but because the technical solutions for comprehensive utilization have not been well solved, most of the molasses alcohol waste mash has been discharged as waste liquid for a long time, not only failed to be well The use of this resource will cause serious environmental pollution

[0003] Since the 1970s, there have been patent literature reports about molasses alcohol waste mash as fertilizer. Before 2008, the technical scheme still remained at adopting molasses alcohol waste mash or the concentrate of molasses alcohol waste mash to directly use it as fertilizer in In the field, because it is not easy to transport and needs to be covered with plastic film after application, it has not been introduced to the market on a large scale.

However, the technical problems in the following three aspects have not been solved well: one is the situation of excessive heavy metals, which may affect the activity of biological strains, resulting in poor fermentation effects and poor product quality in subsequent fermentation processes. The second is that the existing technology proposes a technical solution that puts Bacillus coagulans in a high temperature state and does not maintain the temperature, resulting in the possibility that spoilage bacteria may not be effectively removed. It is possible that Bacillus coagulans and molasses alcohol waste mash may be caused by temperature drop Third, the pH value of the molasses alcohol waste mash was not adjusted in time before anaerobic fermentation, which may lead to poor anaerobic fermentation effect
