Cold diffusion remediation rod based on organic contaminated soil

Abstract

The invention discloses a cold diffusion remediation rod based on organic contaminated soil, and belongs to the technical field of soil remediation. According to the scheme, an embedded remediation rod is inserted into the organic contaminated soil, the top end of a remediation storage barrel is pressed, barium hydroxide octahydrate and ammonium chloride powder in the remediation storage barrel are promoted to be mixed with each other, refrigeration can also be achieved while ammonia gas is generated, along with the gradual increase of the ammonia gas, a movable plug plate can be pushed to slide downwards, and the soil remediation agent is extruded into a lateral diffusion hose, so that on one hand, a sealing plug can be moved out of a second flow division guide hole, and the soil remediation agent in the lateral diffusion hose is promoted to be released from the second flow division guide hole, and on the other hand, by virtue of temperature reduction during refrigeration, a tractionmoving ball is driven to be magnetically shielded, so that the traction moving ball drives the lateral diffusion hoses to be separated from each other and spread, the release range of the soil remediation agent is widened, soil can be stirred and dispersed, and the absorption efficiency of the soil to the soil remediation agent is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a cold diffusion remediation rod based on organic polluted soil. 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] "High pollution exceeding the standard rate", "trillion-level market", "complex system engineering", "emerging industries in the early stages of development", China's soil pollution prevention and control is affixing these la...

Problems solved by technology

However, many experts said that although the cake is big, it cannot be blindly optimistic. Due to multiple barriers such as technology, capital, and business models, it is unrealistic for the soil remediation industry to grow bigger in a short period of time.

[0005] In the prior art, when repairing the soil contaminated by organic matter, it is necessary to add soil repair agent to the soil, and continue to plow the soil, which is troublesome and greatly reduces the efficiency of soil repair
