Farmland soil heavy metal remediation device based on micro-nano bubble immobilized organism stability

Abstract

The invention discloses a farmland soil heavy metal remediation device based on micro-nano bubble fixed biological stability, the bottom of a telescopic joint is communicated with a third pipe body, one end of the outer wall of a fluted disc is in meshed connection with a gear, the top of the gear is fixedly connected with a motor, and the motor is mounted at one end of the bottom of the inner wall of a box body. The outer wall of the motor is in clearance fit with the inner wall of the bent plate, and the output end of the motor is rotationally connected with the box body through a bearing. According to the farmland soil heavy metal remediation device based on the micro-nano bubble fixed organism stability, a micro-nano bubble generator, a motor and a pump body are all connected with an external power source, so that the micro-nano bubble generator processes remediation liquid in a box body, the remediation liquid is injected into a first pipe body, a second pipe body and the like through the pump body, and the remediation liquid is sprayed through a spray head; and when the spray head sprays, the splashing area of the spray head is enlarged, the land restoration range is widened, stable rotation is conducted, and the rotation stability of the spray head is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a bio-stabilized farmland soil heavy metal remediation device based on micro-nano bubble immobilization. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. method. [0003] Although the existing farmland soil heavy metal restoration device can carry out heavy metal restoration on the soil, when the existing farmland soil heavy metal restoration device is working, the spraying range of the nozzle is limited, and it is impossible to spray the liquid medicine in a large area, and the working efficiency is low. question. Contents of the invention [0004] The purp...
