Problems solved by technology

[0004] At present, the main methods for treating waste pollutants in sugar factories are: agricultural irrigation method, oxidation pond method, concentration method, etc. These methods require a lot of investment and have a long treatment cycle, so they cannot be used as an effective method for treating waste in sugar factories.

Embodiment

[0043] S1. According to the ratio of mixing 3 kg of fermentation bacteria per ton of sugar factory filter mud to obtain the first mixed raw materials, 3 kg of fermented bacteria contain 1 kg of yeast, 0.5 kg of lactic acid bacteria, and 1.5 kg of Bacillus subtilis; adjust the first mixed raw materials The moisture contained in the rice is 45%~55%.

[0044]S2, open-type pre-stack fermentation of the first mixed raw materials obtained in step S1 to obtain a pre-fermentation product, when performing pre-stack fermentation, the first mixed raw materials are piled into a strip with a height of 0.6 to 0.8 meters and a width of 1 to 1.5 meters ; Pre-stack, cover and ferment for 3-4 hours, and the fermentation temperature reaches 37-40 degrees Celsius.

[0045] The above-mentioned open pre-stacking fermentation is aerobic fermentation. The lactic acid bacteria group and the yeast group have deodorizing functions, and can decompose organic substances, organic sulfides and organic nitro...

Abstract

The invention provides a method for preparing an organic fertilizer by using sugar refinery filter mud. According to the invention, sugar refinery filter mud is subjected to three fermentations, and aerobic fermentation and anaerobic fermentation are combined, such that the disadvantages of large occupation area and easy damage on fertilizer nutrients of full aerobic fermentation are overcome, thedisadvantages of easy odor generation and long composting time of full anaerobic fermentation are overcome, the deodorization, the decomposition, the insect killing and the sterilization on filter mud are accelerated, and the filter mud is completely composted and fermented; and the preparation method is further suitable for preparing organic fertilizers with high organic matter content by utilizing crop straws, livestock and poultry manure and other raw materials.

Description

technical field [0001] The invention discloses a method for preparing organic fertilizers by using sugar factory filter mud, and in particular relates to a method for preparing organic fertilizers. Background technique [0002] The sugar industry is a major economic player in sugarcane production areas, but also a major environmental polluter. Today, with the increasing awareness of environmental protection, sugar factory waste and pollutants have become the most important factors restricting the development of sugar factories. If the pollution cannot be thoroughly controlled, sugar Waste pollutants from the factories can even threaten the survival of the sugar factories themselves. [0003] In the production process of my country's sugar enterprises, it is inevitable to produce a huge amount of waste pollutants such as alcohol waste liquid, filter mud, bagasse, sugarcane pith, among which bagasse and sugarcane pith can be effectively used as papermaking raw materials, and t...
