Remediation method for applying humic acid to soil remediation

Abstract

The invention relates to the technical field of soil remediation, and discloses a remediation method for applying humic acid to soil remediation, which comprises the following steps: preparing humic acid:acidic factors in a humic acid structure with peat, lignite or weathered coal as main raw materials are subjected to a chemical reaction with an alkali, so that ahumate is produced, humic acid contained in lignite is extracted through a potassium hydroxide solution with a certain concentration to obtain potassium humate, and the subsequent preparation processes are divided into two processes,namely dry humic acid processing and wet humic acid processing. According to the remediation method for applying humic acid to soil remediation, advantages of reducing adhesion in the production process, improving the soil remediation effect and the like are achieved;the problemthat in the soil remediation agent preparation process in the prior art, the phenomenon of adhesion is likely to occur inthe smashing and mixing process is solved, the remediation effect still has a certain optimizing and improving space, and therefore the remediation method for applying humic acid to soil remediationis provided for solving the proposed problems.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a remediation method in which humic acid is applied to soil remediation. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. 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 types: physical, chemical and biological. Methods: 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, with "high pollution exceeding the standard rate" and "trillion-level scale" market", "complex system engineering" and "emerging industries in the early stages of development", China's soil pollution prevention and cont...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for applying humic acid to soil remediation, which has the advantages of reducing stickiness in the production process and improving the effect of soil remediation, and solves the problem of the soil remediation agent and its preparation. The method is a very potential restoration method, but in the process of configuration, it is prone to sticking phenomenon in the process of crushing and mixing, and the repair effect of this method still has a certain room for optimization and improvement, so a humic acid application is proposed Remediation methods based on soil remediation to solve the problems raised above
