Automatic repair equipment for polluted soil

Abstract

The invention relates to automatic repair equipment for polluted soil and belongs to the field of environment protection machines. The automatic repair equipment comprises a soil liquefying device and a soil repair device. The soil liquefying device comprises a mixing pool, a water inlet pipe and a slurry pump. A viscosity sensor is arranged in the mixing pool. An electromagnetic valve is arranged on the water inlet pipe. The slurry pump is connected with the mixing pool through a pipeline. The soil repair device comprises a shell. The shell is internally divided into an upper part and a lower part through a partition plate, a tail gas treating pool and a reaction tank are located on the upper part and the lower part of the shell respectively, and the tail gas treating pool and the reaction tank are connected through a tail gas connecting pipe. The automatic repair equipment has the beneficial effects of being high in automation degree, good in treatment effect and the like.

Description

technical field [0001] The invention relates to an automatic restoration device for polluted soil, which belongs to the field of environmental protection. Background technique [0002] In the past 20 years, with the continuous deepening of industrialization, urbanization, and rural intensification in my country, the problem of soil pollution has increased day by day. The worsening of soil pollution and the non-renewable characteristics of soil have become a major problem restricting the continued development of our country. Solving the problem of soil pollution has become an urgent need for our country to achieve sustainable development. [0003] The current common treatment methods for soil pollution are as follows: [0004] 1 Chemical leaching method: the process of injecting a leaching agent into contaminated soil or sediments to elute and clean pollutants in the soil. This technology has the advantages of flexible operation, stable repair effect, short cycle and high e...

AI Technical Summary

Problems solved by technology

This technology has the advantages of flexible operation, stable repair effect, short cycle and high efficiency. However, this technology has limited application range, high cost and will cause secondary pollution

[0005] 2 Biological method: the use of microbial degradation to remediate soil pollution is a common remediation technology in daily life. This method has good treatment effect, low treatment cost, and will not cause secondary pollution, but the remediation rate is slow and achieves regulation. Levels take quite a while

This method takes a long time to restore. Due to the use of natural volatilization, the removal of pollutants is not complete, and the treatment effect is not ideal.

[0008] The application number is 201210383050.3, and the title of the invention is a contaminated soil remediation system and method, which discloses a method of treating polluted soil using thermal desorption and a thermal desorption device, although it solves the technical problem that the equipment does not rely on imports from the function , but the overall structure of the device is relatively complex, after a long time of operation, the efficiency decreases rapidly, the processing effect is not ideal, and the degree of automation of the equipment is low
