Efficient repairing agent for polluted soil and preparation method of efficient repairing agent

Abstract

The invention relates to the technical field of environmental treatment, in particular to an efficient remediation agent for contaminated soil and a preparation method of the efficient remediation agent, and aims at solving the problems that in the prior art, a soil remediation agent is prone to secondary pollution and poor in soil remediation effect, the following scheme is provided, the efficient remediation agent comprises 30-70 parts of biological agent and 10-30 parts of chemical agent, the biological agent comprises the following components in parts by mass: 15-30 parts of a yeast culture, 10-20 parts of a zoogloea culture, 10-20 parts of a sulfuric acid reducing bacteria culture, 10-20 parts of a citrobacter culture and 10-20 parts of a nitrifying bacteria culture, and the chemical agent and the biological agent are prepared from the following components in parts by mass: 15-30 parts of a yeast culture, 10-20 parts of a zoogloea culture, 10-20 parts of a sulfuric acid reducing bacteria culture, 10-20 parts of a citrobacter culture and 10-20 parts of a nitrifying bacteria culture. The soil remediation agent not only effectively ensures that the soil remediation agent does not cause secondary pollution to soil, but also can be quickly formed, the use effect of the soil remediation agent is effectively ensured, and the soil remediation agent is easy to popularize and use.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a high-efficiency remediation agent for polluted soil and a preparation method thereof. Background technique [0002] Due to the rapid population growth and rapid industrial development, solid wastes are continuously piled on the soil surface, sewage is dumped at will, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. Soil pollution has become a global environmental pollution problem. [0003] The main methods of soil pollution control in the prior art include engineering physical and chemical methods, agricultural chemical regulation methods, and biological remediation. However, traditional soil remediation methods are often complicated to operate, high in cost, and prone to secondary pollution. Traditional soil remedi...
