Composite soil remediation agent made from compost and preparation method

Abstract

The invention discloses a composite soil remediation agent made from compost and a preparation method. Vigorous implementation of soil remediation is a primary task for protecting soil ecological environments and solving land resource scarcity. The composite soil remediation agent made from the compost comprises, by weight, 60-70 parts of compost materials, 10-15 parts of straw biomass charcoal, 20 parts of coal ash, 2-5 parts of zeolite powder, 3-5 parts of calcium magnesium phosphate fertilizer, 0.5-2 parts of composite microbial agents and 0.5-1 part of binder. The composite soil remediation agent and the preparation method have the advantages that the substances are combined organically, formula and production process are optimized reasonably, the composite soil remediation agent with functions of fertilizing, purifying and remediating the soil and promoting crop growth and development is provided for soil remediation, and accordingly, healthy, green and sustainable agriculture is promoted. The composite soil remediation agent is applied to soil remediation as well as biofertilizer and waste resource utilization.

Description

[0001] Technical field: [0002] The invention relates to a composite soil restoration agent using compost as raw material and a preparation method thereof. [0003] Background technique: [0004] Wastewater, waste gas, and waste residues produced by industrial development, agricultural production, and residents' lives are discharged into the environment, causing serious soil pollution and bringing huge adverse effects on social production and people's lives. Therefore, vigorously implementing soil restoration is the primary task of protecting the soil ecological environment and solving the shortage of land resources. Soil remediation techniques are generally divided into physical remediation, chemical remediation, biological remediation, ecological engineering remediation and joint remediation. As an important means to solve the problem of soil pollution, soil remediation technology has been highly concerned by experts and scholars at home and abroad, and has been widely used...

Problems solved by technology

However, there are many deficiencies and problems to be solved urgently in soil remediation technology.

For example, physical and chemical soil remediation methods have limitations, high technical costs, and are difficult to apply on a large scale; and phytoremediation not only takes a long time but also needs further research on post-harvest treatment of plants
