Production method of zeolite tailings compressed nutrient soil

Abstract

The invention discloses a production method of zeolite tailings compressed nutrient soil. The key point of the technical scheme is that the production method comprises the following steps: first, acidifying zeolite tailings and sludge; then, packaging into a finished product after carrying out stirring, compression and microwave low-temperature sterilization on ingredients of the zeolite tailings compressed nutrient soil. The zeolite tailings compressed nutrient soil is prepared from the following raw materials such as acidified zeolite tailings, acidified sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, hyperviscous attapulgite, biogas slurry, biogas residues, smashed plant fibers, expanded vermiculite, expanded perlite and super absorbent resin. The zeolite tailings compressed nutrient soil contains a plenty of nitrogen, phosphorus, potassium, organic matters and various microelements and can provide nutrient elements required by plant growth and reduce the damage on the plants caused by pathogenic bacteria and injurious insects, thereby facilitating normal growth and development of the plants and protecting the ecological environment. The production method of the zeolite tailings compressed nutrient soil is suitable for producing zeolite tailings compressed nutrient soil with different formulae.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of zeolite tailings compressed nutrient soil. Background technique [0002] Due to some structural defects in natural zeolite, such as superposition defects of the crystal lattice, the internal pores are obstructed, so the pore diameter of natural zeolite is smaller than that of synthetic zeolite, and it is difficult to exert its structural characteristics in applications. [0003] There are a large number of zeolite tailings in the zeolite mining area, which have not been well developed and utilized. After the zeolite tailings are acidified, the adsorption performance can be improved. [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, parasite eggs, heavy metals, etc. Toxic and...

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
