Soil beneficial to adsorption and decomposition of hazardous substances and preparation method thereof and application of soil

Abstract

The invention provides soil beneficial to adsorption and decomposition of hazardous substances and a preparation method thereof and application of the soil. The preparation method comprises the following steps: compound bacteria are mixed in proportion and are activated, an obtained activated bacteria solution is added into wormcast soil in proportion, the prepared soil is put in a culture area, a0.05% formaldehyde solution is delivered into the culture area after the culture area is closed, and closed culture is performed for 72-120 hours to obtain a soil finished product. The soil beneficial to adsorption and decomposition of the hazardous substances is prepared by the preparation method, and in application of the soil, the soil is used for cultivating special plants for air purification and is made into a hazardous substance adsorption purification bag; the closed culture is performed on the prepared soil, and the formaldehyde solution is delivered into the culture area, and the like to stimulate degrading bacteria in florae to continuously degrade and adapt to be enhanced in activity, and the structure of the florae in the soil is regulated, and after culture ends, a large number of active degradation florae are present in the soil, thus increasing soil fertility and various trace elements. The soil can be used as the core of air purification formula soil different in function.

Description

technical field [0001] The invention belongs to the technical field of indoor air pollution ecological control, and in particular relates to a soil which is beneficial to absorbing and decomposing harmful substances and its application. Background technique [0002] At present, the most effective treatment method for environmental pollution and heavy industrial pollution is the biological treatment method, which quickly degrades pollutants through targeted cultured active microbial populations. It is mostly used in industrial polluted wastewater, waste gas, domestic garbage, agricultural breeding, etc. There are few studies on soil adsorption and decomposition of harmful substances, and large-scale soil pollution cannot be effectively solved. [0003] Many microorganisms in nature have the ability to phagocytize and decompose harmful substances. There are many degrading bacteria for the decomposition of harmful gas pollution such as formaldehyde, TVOC, and benzene series, ma...

Problems solved by technology

[0005] The purpose of the present invention is to solve the poor ability of ordinary soil to absorb and decompose harmful substances existing in the prior art, which cannot effectively solve large-area soil pollution, let alone effectively absorb and decompose harmful gases remaining in the air, and provides a method that is beneficial to adsorption and decomposition The soil of harmful substances and its preparation method and application, through reasonable soil selection and the addition of microbial flora, can greatly increase the ability of the soil to absorb and decompose harmful substances such as formaldehyde, and at the same time provide plants with more uniform nutrition and promote healthy plant growth. Applied to the cultivation of special plants for air purification; it can be made into harmful substance adsorption purification bags to replace traditional adsorption products such as activated carbon bags, and has long-term effective and continuous activity
