Efficient soil remediation improver and preparation method thereof

Abstract

The invention discloses an efficient soil remediation improver and a preparation method thereof in the technical field of soil remediation, wherein the efficient soil remediation improver comprises the following raw materials in parts by weight: 60-70 parts of sepiolite powder, 15-20 parts of zeolite powder, 5-8 parts of fly ash, 6-9 parts of limestone, 3-7 parts of bentonite, 15-25 parts of organic matter, 5-8 parts of a trace element supplement, 3-5 parts of photosynthetic bacteria, 2-3 parts of bacillus megaterium, 1-2 parts of bacillus subtilis, 1-2 parts of bacillus mucilaginosus and 5-8parts of bacillus licheniformis. Filtrate, the bacillus licheniformis and the zeolite powder are mixed to obtain a soil remediation and improvement auxiliary liquid, residual microbial bacteria in thefiltrate are fully utilized, and waste of the microbial bacteria is avoided; the soil remediation and improvement auxiliary liquid is applied to soil firstly, the bacillus licheniformis can effectively inhibit propagation of harmful bacteria, then the soil remediation and improvement agent is applied to the soil, propagation of the microbial bacteria is facilitated, degradation-resistant organicmatter in the soil is efficiently decomposed, and the fertility of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a high-efficiency soil remediation improver and a preparation method thereof. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. [0003] Soil remediation improver is a new type of biological strain in the form of powder, which has the characteristics of rapid reproduction, strong vitality, safety, non-toxicity, high temperature resistance, no inac...

AI Technical Summary

Problems solved by technology

[0005] The soil remediation improver in the prior art is directly made by mixing microbial agents and organic matter, but the content of microbial bacteria loaded on the carrier is low, resulting in a large amount of soil remediation improver and the effect is relatively general; moreover, in the soil to be improved There are often more harmful bacteria, which are easy to compete with the microbial bacteria of the soil remediation improver, reducing the effectiveness of the soil remediation improver
