Mobile field solar microbial remediation system

Abstract

The invention discloses a mobile field solar microbial remediation system, and belongs to the technical field of environmental remediation. The remediation system comprises a microorganism culture module, a solar power generation module and a vehicle-mounted mobile module, the microorganism culture module and the solar power generation module are both installed on the vehicle-mounted mobile module, the solar power generation module provides electric energy for the microorganism culture module, the microorganism culture module is arranged for enlarging culture of microorganisms, and the vehicle-mounted mobile module is arranged on the vehicle-mounted mobile module. According to the remediation system, a solar power generation mode is adopted as an electric power source, the solar power generation module, the microorganism culture module and the vehicle-mounted mobile module are organically combined, the mobility of microorganism culture and addition is achieved, and the problem that when soil remediation work is carried out in most remote mountainous areas and sites, the microorganism culture module and the vehicle-mounted mobile module are not needed is solved. And transportation, assembly and power supply of the equipment are all restricted.

Description

Technical field [0001] The present invention relates to the field of contaminated soil remediation technology, in particular to a mobile field solar microbial remediation system. Background [0002] The commonly used remediation methods of contaminated soil are mainly phytoremediation, microbial remediation, chemical remediation, physical remediation, etc., of which the application of heavy metal pollution soil engineering is more solidification / stabilization technology, but the long-term stability of its remediation effect is difficult to guarantee, and the cost is high, the use of microbial remediation has the advantages of low treatment cost, low secondary pollution risk, high efficiency, in recent years by the practitioners of widespread concern and carried out a lot of research. When repairing soil contaminated by heavy metals, it is usually remedied by biomineralization, using microorganisms to react with heavy metals in soil oxidation-reduction, so that some heavy metals...

Problems solved by technology

[0003] But at present, because such microorganisms (such as sulfate-reducing bacteria, Shewanella) are usually strict anaerobic microorganisms, the cultivation conditions are harsh, and they are directly put into the soil and groundwater and are easily affected by the environment, and the survival rate of microorganisms is not high. Soil microbial remediation technology adopts fixed-site cultivation and long-distance dosing, so engineering applications are limited. Usually, such projects are located in remote mountainous areas, where equipment installation is complicated and energy supply is inconvenient, resulting in constraints on equipment transportation, assembly, and power supply. Different degrees of constraints
