Production method of zeolite compressed nutrient soil

Abstract

The invention discloses a method for producing zeolite compressed nutritional soil. The key point of the technical scheme of the invention is as follows: zeolite and sludge are subjected to acidification treatment firstly, then, ingredients of the zeolite 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 zeolite compressed nutritional soil is prepared from materials, such as acidified zeolite, acidified sludge, instant-dissolved sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high-viscosity attapulgite, biogas liquid, biogas residue, crushed plant fiber, expanded vermiculite, expanded perlite, super-absorbent resin and the like. The zeolite 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, the normal growth and development of the plants and the protection to the ecological environment are facilitated, and the secondary pollution to the surrounding environment is avoided. The method for producing the zeolite compressed nutritional soil is suitable for producing zeolite compressed nutritional soil of different formulations.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of zeolite 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] After the zeolite is 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 harmful substances will cause serious harm to the environment if they are not effectively treated and disposed of. [0005] The water conte...

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
