Problems solved by technology

If these wastes are discharged directly without treatment, they will cause serious pollution to water sources and the surrounding environment.
Although there is no lack of treatment methods in the prior art, there are problems such as large energy consumption, high operating costs, incomplete treatment, and easy to cause secondary pollution.

Embodiment 1

[0020] Put 10 parts of waste molasses in a fermenter, dilute with 50 parts of water, filter, add 0.1 part of sulfuric acid, adjust the pH value to 4.5-5.0; seal the fermenter, heat it to 20°C while stirring, and use an air compressor to carry out Unintermittent aeration treatment, the incoming air is treated and filtered by an activated carbon tank; after stirring for 2 days, stop heating when the liquid in the tank begins to ferment and heat up naturally, and when the temperature in the tank reaches 35°C, open the tank and add 0.3 parts of ammonium sulfate, Then airtightly stir again for 2 days, during which there is no intermittent aeration treatment; open the tank, add 4 parts of urea, 3 parts of monoammonium phosphate and 4 parts of potassium sulfate in sequence, airtightly stir for 1 day, and pasteurize to obtain organic liquid fertilizer.

Embodiment 2

[0022] Repeat Example 1, with the following differences: the raw materials added are respectively 20 parts of waste molasses, 0.5 part of ammonium sulfate, 4.3 parts of urea, 6 parts of monoammonium phosphate, 6 parts of potassium sulfate, 63 parts of water, and 0.15 part of sulfuric acid.

Embodiment 3

[0024] Repeat Example 1, the following differences are arranged: 30 parts of molasses, 0.8 part of ammonium sulfate, 4.5 parts of urea, 8 parts of monoammonium phosphate, 8 parts of potassium sulfate, 70 parts of water, 0.2 part of sulfuric acid.

Abstract

The present invention discloses an organic liquid fertilizer and its preparation method. It utilizes the molasses produced in production process of white granulated sugar as main raw material, and makes it undergo a series of steps of dilution, filtration, pH value regulation, fermentation and pasteurization to obtain the invented final product richly containing the elements of nitrogen, phosphorus and potassium, etc.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, and in particular relates to an organic liquid fertilizer and a preparation method thereof. Background technique [0002] my country is a big agricultural country. Since ancient times, organic fertilizer has been used as the basic fertilizer for agricultural and forestry production. However, with the rapid development of the planting industry, it has gradually become the consensus of many people that the application of chemical fertilizers is simple and quick-acting, and can quickly increase production. However, the long-term use of chemical fertilizers will lead to excessive consumption of a large amount of non-renewable energy and soil fertility decline. In order to cope with this situation, people have to gradually increase the amount of chemical fertilizers, forming a vicious circle, which leads to increasingly serious negative effects on the ecological environment and...
