Continuous soil bioremediation reactor and remediation method thereof

Abstract

The invention discloses a continuous soil bioremediation reactor and a remediation method thereof, belonging to the technical field of soil remediation. The continuous soil bioremediation reactor comprises supporting combined equipment and bioreactor equipment, wherein the supporting combined equipment comprises a plurality of skid-mounted frames; the biological reaction equipment comprises a plurality of bioreactors; each bioreactor comprises a support connecting part, a stirring part, a sensor probe and a dosing spraying device; the plurality of bioreactors are respectively arranged at the bottoms of the plurality of skid-mounted frames; the stirring parts are arranged at the central parts of the support connecting parts; and the dosing spraying devices are arranged on the inner side walls of the upper parts of the support connecting parts. In the prior art, each batch of soil remediation bioreactors need to be subjected to microbial acclimation, soil physicochemical property adjustment, reaction environment remodeling and other procedures, operation and maintenance are tedious and time-consuming, and the bioreactors cannot continuously operate and have the problems of low efficiency, small treatment capacity, unstable effect and the like.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a continuous soil bioremediation reactor and a restoration method thereof. Background technique [0002] Extensive industrial and agricultural activities of human beings often lead to soil pollution. Common soil pollution includes heavy metal pollution and organic pollution. In recent years, countries have begun to attach importance to the control of soil pollution, and its technology has developed very rapidly. Among them, bioremediation technology is considered to have the most vitality. At present, the soil bioremediation technologies used include in-situ treatment, on-site treatment and bioreactors. Bioreactors can give full play to the advantages of biological methods and are the most effective treatment process in bioremediation technologies for contaminated soil. The main structure of the machine is usually a sealed cylinder, the treatment method is sequence bat...
