Soil remediation agent used for anaerobic microorganisms and application of soil remediation agent used for anaerobic microorganisms

Abstract

The invention provides a soil remediation agent used for anaerobic microorganisms. The soil remediation agent used for the anaerobic microorganisms is characterized by being produced by mixing the following raw materials in parts by mass: 20-50 parts of an ammonium salt, 15-45 parts of a carbonate, 10-30 parts of humus soil, 10-20 parts of crushed straw, 20-30 parts of a phosphamide-containing matter, 10 parts of hydrogen production stone and 10-20 parts of emulsified plant oil. The soil remediation agent used for the anaerobic microorganisms can be suitable for remediation of deep soil with low or medium concentration pollution, and remediation effects which are more effective, more economic, more convenient and free from pollution are achieved.

Description

Technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation agent for anaerobic microorganisms and its application. Background technique [0002] Soil resources are precious natural resources. In order to make effective use of soil resources and in line with sustainable development, it is usually necessary to repair contaminated soil through soil remediation technical measures to restore normal functions. In the current soil remediation project, there are still some shortcomings in the soil remediation of sites with medium or low concentrations of organic pollution: the thermal desorption method is adopted, the remediation cost is high, the energy consumption is large, and the remediation period is long. Needs later optimization; using traditional chemical agent oxidation method, chemical agents have almost no remediation effect on trace pollution, and for soil with low concentration of pollutants, its remediation e...

AI Technical Summary

Problems solved by technology

At present, in soil remediation projects, there are still some deficiencies in the soil remediation of sites with medium or low concentration of organic pollution: using thermal desorption method, the remediation cost is high, the energy consumption is large, the remediation period is long, and the remediation site is still Post-optimization is required; the traditional chemical agent oxidation method has almost no remedial effect on trace pollution, and for soils with low concentrations of pollutants, the remediation efficiency is low and there is a risk of secondary pollution; while the microbial method Due to the uncontrollability of the pre-screening process, the project cycle may be prolonged, and the remediation effect on some biologically toxic pollutants is poor

In the current soil remediation projects, there are still some deficiencies in the soil remediation of sites with medium or low concentration of organic pollution: using thermal desorption method, the remediation cost is high, the energy consumption is large, the remediation period is long, and the remediation site Post-optimization is still needed; the traditional chemical oxidation method has almost no remediation effect on trace pollution, and for soil with low concentration pollutants, the remediation efficiency is low and there is a risk of secondary pollution; while the use of microorganisms Due to the uncontrollability of the pre-screening process, the project cycle may be prolonged, and the remediation effect on some biologically toxic pollutants is poor.

In addition, the microbes in the deep soil and the shallow soil are different, and specific repair methods should be used to treat them differently. If the above-mentioned general repair methods are generally used for repair, the repair effect may not be good.
