Problems solved by technology

At present, most cassava starch manufacturers have a very low utilization rate of the large amount of sludge generated in production. Usually, the cassava industrial sludge is simply mechanically dehydrated and then transported to the dry plant for stacking, resulting in a huge waste of resources.
The COD and BOD of alcohol waste mash are very high, the pH value is low, and it also contains a large amount of organic matter, nitrogen, potassium and other components. If it is not treated and discharged directly, it will pollute the environment and cause useful nitrogen. , Potassium and other fertilizer resources waste

Abstract

Relating to the field of fertilizer preparation, the invention provides an organic fertilizer prepared from cassava industrial waste and a preparation method thereof. The organic fertilizer includes the following components by weight: cassava dregs, cassava industrial sludge, alcoholic fermentation waste liquid, bentonite, mushroom residue, rice husk powder, waste silk, a compound fertilizer, a microelement fertilizer and a microbial inoculant. The preparation method of the organic fertilizer includes: raw material preparation, aerobic fermentation, anaerobic fermentation, mixing and granulation. The organic fertilizer adopts biodegradable cassava dregs, mushroom residue, rice husk powder, waste silk and cassava industrial sludge for fermentation, and is then added with the compound fertilizer and microelement fertilizer. The prepared organic fertilizer not only has rich and balanced nutrition, but also provides nutrients and trace elements needed by plant growth, also makes good use of waste materials, saves resources and reduces environmental pollution.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to an organic fertilizer prepared from cassava industrial waste and a preparation method thereof. Background technique [0002] my country is a large agricultural country, but with a large population and little land, the arable land area is only about 10% of the total land area, and the average per capita arable land is only 0.08 hectares. As an important agricultural product, chemical fertilizer plays a significant role in increasing crop yield and is an indispensable factor of production in modern agriculture. [0003] According to the statistics of the National Fertilizer Network, the seasonal utilization rate of nitrogen fertilizer in foreign countries is 60%-70%, while the seasonal utilization rate of nitrogen fertilizer in my country is 30%-35%, phosphate fertilizer is 10%-25%, and potash fertilizer is 35%-50%. The low utilization rate of inorganic fertilizer hinders the...
