Problems solved by technology

The disposal of waste white clay as waste not only increases the economic burden of the enterprise, but also pollutes the environment and endangers the quality of groundwater if it is not treated in time. Moreover, since the oil contained in it is unsaturated fat, it is easy to occur when it is directly exposed to the air. Spontaneous combustion, causing fire, causing harm to people's lives and property

Embodiment 1

[0051] A waste clay-based organic fertilizer of this embodiment is calculated on a dry basis. The organic fertilizer is prepared from the following components in mass percent: 30 kg of waste clay, 5 kg of chaff ash, 10 kg of tea dregs, 5kg of phytic acid, 10kg of rice bran meal, 30kg of livestock and poultry manure, and 10kg of rice straw, of which: the total mass of each component is 100kg.

[0052] The above-mentioned waste clay-based organic fertilizer of the present embodiment is prepared by the following method, including the following steps:

[0053] (1) Selection of raw materials for composting

[0054] Waste white clay: high organic matter content, strong adsorption, good deodorization, can prevent and reduce the volatilization of ammonia, comprehensive nutrients, clean and hygienic, low raw material cost.

[0055] Chaff ash: Alkaline, high in silicon and potassium, strong in adsorption, good for nutrient retention;

[0056] Tea dregs and rice bran dregs: high in eff...

Embodiment 2

[0068] A kind of waste clay-based organic fertilizer of the present embodiment is calculated on a dry basis, and the organic fertilizer is prepared from the raw materials of the following components in mass percent: 20 kg of waste clay, 7.5 kg of chaff ash, 15 kg of tea dregs, Humic acid 7.5kg, rice bran meal 15kg, livestock and poultry manure 30kg, fungus residue 5kg, of which: the total mass of each component is 100kg.

[0069] This example adopts the same preparation method as Example 1 to prepare the organic fertilizer, the only difference being that the quality of the raw material components is different.

Embodiment 3

[0071] A kind of waste clay-based organic fertilizer of the present embodiment is calculated on a dry basis, and the organic fertilizer is prepared from the following components in mass percent: 30 kg of waste clay, 2.5 kg of chaff ash, 5 kg of tea dregs, Humic acid 2.5kg, rice bran meal 10kg, livestock manure 40kg, rice straw 10kg, of which: the total mass of each component is 100kg.

[0072] This example adopts the same preparation method as Example 1 to prepare the organic fertilizer, the only difference being that the quality of the raw material components is different.

Abstract

The invention relates to a spent bleaching clay-based organic fertilizer, and a preparation method and an application thereof, and belongs to the technical field of organic fertilizers. The organic fertilizer is prepared from 20-30% of spent bleaching clay, 2.5-7.5% of rice husk ash, 5-15% of tea seed meal, 2.5-7.5% of humic acid, 5-15% of rice bran, 20-40%of livestock and poultry manure, and 5-10% of rice straws or fungus residues. The organic fertilizer can effectively improve the conditions of soil, improve the water retention and fertilizer conservation capacity of the soil, promote the growth of crops, increase the yield and increase the income. The organic fertilizer is prepared from the spent bleaching clay, livestock and poultry manure, rice straws and other wastes, so the problemof recycling of various agricultural wastes is solved. The organic fertilizer can be applied to the production of green agricultural products, reduces pollution, protects the ecological environment, and improves the production efficiency and the economic benefit of an enterprise, so the organic fertilizer has a very broad development prospect.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and relates to a waste clay-based organic fertilizer and a preparation method and application thereof. Background technique [0002] At present, domestic waste white clay treatment is limited by technical and economic conditions, and its comprehensive treatment technology is absent. The resource development and utilization rate of waste white clay is very low. Most refineries treat it as waste, or by individuals or small workshops. After simply pressing and extracting oil, it is discarded at will, and a small part of the waste clay is reused, but all of them have their shortcomings. Still unresolved; or use the clay properties of waste white clay as cement mixing ingredients, but the production technology is complicated and low added value; or use its high combustion value as cement auxiliary fuel, but waste white clay is easy to generate dust during the combustion process, which may ...
