Production method of bentonite tailings compressed nutrient soil

Abstract

The invention discloses a method for producing bentonite tailing compressed nutritional soil. The key point of the technical scheme of the invention is as follows: bentonite tailings and sludge are subjected to acidification treatment firstly, then, ingredients of the bentonite tailing compressed nutritional soil are subjected to stirring, compressing and microwave low-temperature sterilization, and then, packaging is carried out, so as to produce a finished product. The bentonite tailing compressed nutritional soil is prepared from materials, such as acidified bentonite tailings, acidified sludge, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite, biogas liquid, crushed plant fiber, expanded vermiculite, expanded perlite, super-absorbent resin and the like. The bentonite tailing compressed nutritional soil contains a large number of nitrogen, phosphorus, potassium, organic matters and a variety of microelements, so that nutrient elements necessary for the growth of plants can be provided, the harm to the plants caused by pathogenic bacteria and pests is reduced, and the normal growth and development of the plants and the protection to the ecological environment are facilitated; the method for producing the bentonite tailing compressed nutritional soil is suitable for producing bentonite tailing compressed nutritional soil of different formulations.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of bentonite tailings compressed nutrient soil. Background technique [0002] Bentonite is a kind of clay rock, also known as montmorillonite clay rock, which often contains a small amount of illite, kaolinite, halloysite, chlorite, zeolite, quartz, feldspar, calcite, etc. Some bentonite is loose like soil, Some are dense and hard, and the main chemical components are silicon dioxide, aluminum oxide and water, and also contain iron, magnesium, calcium, sodium, potassium and other elements. [0003] There are a large amount of bentonite tailings in the bentonite mining area, which have not been well developed and utilized. [0004] Sludge is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It enriches the pollutants in sewage, contains a large amount of nutrients such as nitrogen and phosphorus, organic matter, virus microorganisms, parasi...

AI Technical Summary

Problems solved by technology

Generally, it is prepared by mixing fertile field soil and decomposed manure. There are also nutrient soils selected from imported high-quality peat and coconut bran mixed in a specific proportion. However, these nutrient soils have not undergone reasonable ingredients and strict disinfection. Conducive to the normal growth and development of seedlings

[0009] Because the treated nutrient soil is relatively light and loose, the conventional product of nutrient soil is relatively large, which is not conducive to reducing the cost of production and transportation
