Abstract

The invention discloses a biomass charcoal based soil repair agent, which is prepared from, by weight, 60-80 parts of biomass charcoal, 30-50 parts of crops straw, 15-25 parts of kieselguhr, 15-25 parts of sodium bentonite, 15-25 parts of potassium humate, 8-12 parts of sodium lignin sulfonate, 8-12 parts of edetic acid, 8-12 parts of tartaric acid, 5-7 parts of enzymatic hydrolysate, 5-7 parts ofmicroorganism catalytic degrading bacteria, and 5-7 parts of fermenting agent. The invention further discloses a preparation method of the biomass charcoal based soil repair agent. The biomass charcoal based soil repair agent has the advantages of absorbing heavy metal and pollutants in the soil; for the soil repair agent applies pure natural raw material, the soil repair agent can avoid secondary pollution of soil and effectively guarantee the repair efficiency.

Description

technical field [0001] The invention relates to the technical field of preparation of soil remediation agents, in particular to a biochar-based soil remediation agent and a preparation method thereof. Background technique [0002] Soil pollution has become a worldwide problem, and organic pollution, especially persistent organic pollutant pollution, is a major type of soil pollution. According to preliminary statistics, there are at least 13-16 million hectares of arable land polluted by pesticides and other organic substances in my country, and the trend is increasing day by day. Soil pollution can affect the decline of crop yield and quality, and can endanger human health through the food chain, and can also lead to further deterioration of air and water environment quality. Therefore, the control of soil pollution is urgent. [0003] The porous structure of biochar and the abundant oxygen-containing functional groups on the surface make biochar have a strong ability to ...
