Purple soil conditioner prepared from white spirit solid waste and preparation method thereof

Abstract

The invention discloses a purple soil conditioner prepared from white spirit solid waste and a preparation method thereof, and relates to the technical field of soil conditioners and application. The conditioner is prepared from the following raw materials in parts by weight: 30-50 parts of waste distillers' grains, 40-60 parts of blown bran ash, 1-2 parts of sludge, 1-2 parts of a compound fermentation inoculant and 5-10 parts of biogas residues, wherein the compound fermentation inoculant is one or more of bacillus, filamentous fungi, actinomycetes and saccharomycetes. The preparation method of the modifier comprises the following steps: mixing: fully mixing the waste distiller's grains, the blown bran ash and the sludge, and adjusting the moisture content to 55-65% to obtain a mixed raw material; fermentation: adding a compound fermentation inoculant into the mixed raw material, putting into a composting device, carrying out aerobic fermentation for 15-22 days, and then crushing the mixture to obtain an organic fertilizer; raw material processing: fully stirring and mixing the organic fertilizer and the biogas residues to manufacture the soil conditioner. The invention provides a cheap ecological improver for remediation of increasingly worsening soil while realizing zero emission of solid wastes of white spirit brewing enterprises.

Description

technical field [0001] The invention relates to the field of soil improver and its application technology, in particular to a purple soil improver prepared by using liquor solid waste and a preparation method. Background technique [0002] my country is a large agricultural country, and soil resources are the foundation of agriculture. However, due to soil erosion, land desertification, grassland degradation, and rapid expansion of land secondary salinization, the existing fragile soil resources are facing severe challenges. Many The fertile soil that was once suitable for the healthy growth of crops has slowly been transformed into poor soil. Among the 1.826 billion mu of cultivated land in my country, more than half of them are degraded obviously, the cultivated layer becomes shallower, the organic matter decreases, the soil acidifies, the physical and chemical properties deteriorate, the compaction increases, and the ventilation is poor. According to the third national so...

Problems solved by technology

[0013] In order to solve the problems of environmental pollution and resource waste caused by a large amount of solid waste such as discarded grains, blown ash, residual sludge from wastewater treatment, and biogas residues produced in the production process of liquor brewing enterprises, the present invention proposes a method that takes the above solid waste as The method of preparing purple soil ecological improver through the collaborative processing of resources and utilizing the complementary characteristics of nutrient components and physical and chemical properties of each material, realizes "zero discharge" of solid waste in liquor brewing enterprises, and contributes to the deteriorating soil. Restoration provides an inexpensive ecological improver to achieve multiple economic, social and environmental benefits
