Soil remediation device based on drip washing and microbial remediation theory

Abstract

A soil remediation device based on the principles of rinsing and microbial remediation, comprising a housing, a sleeve is arranged inside the housing, the bottom of the sleeve is fixedly connected to the inner side wall of the housing through several fixing rods, and the sleeve is provided with There is a rotating shaft, the top of the rotating shaft extends upwards through the top of the housing, and the top of the rotating shaft is fixedly connected with the output shaft of the motor, and the part of the rotating shaft inside the sleeve is arranged with spiral blades; the upper part of the rotating shaft is symmetrically fixedly connected with two A horizontal rod, the lower side of the other end of the horizontal rod is fixedly connected with a vertical rod, and a plurality of stirring devices are evenly arranged on the vertical rod. The beneficial effect of the present invention is that the motor drives the rotating shaft to rotate, the rotating shaft drives the vertical rod to rotate through the horizontal rod, the vertical rod drives the rotation of the stirring device, and the moving rod on the stirring device is away from the vertical rod after being subjected to centrifugal force, thereby driving the stirring blade The mixing radius is enlarged, and the mixing effect of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation device based on the principles of leaching and microbial remediation. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. 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 methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. [0003] At present, the treatment and remediation of soil pollution can be roughly divided into several categories such as physical, chemical, and biological methods according to their principles. Various met...

Problems solved by technology

Various methods have their own advantages and disadvantages. Among them, the soil leaching repair technology has the advantages of wide application range, quick effect, large processing capacity, and remarkable effect. At the same time, it also has disadvantages such as expensive repair costs and easy to cause secondary pollution; While the technology has the advantages of low cost, easy operation, and no secondary pollution, it also has disadvantages such as low repair efficiency and long repair period for high-concentration pollution.
