Intelligent integrated soil remediation device and method

Abstract

The invention discloses an intelligent integrated soil remediation device and method. The output ends of a crushing and screening system, a stepwise remediation material putting system and a liquid putting system of the device are all connected with the input end of a uniform mixing and stirring system, the output end of the uniform mixing and stirring system is connected with the input end of theuniform mixing and stirring system, and the output end of the uniform mixing and stirring system is connected with a discharging system. The remediation method comprises the operation steps of 1, determining remediation materials which need to be put and the water volume; 2, calculating the use quantity of the required remediation materials and the use amount of liquid; 3, starting all the systems; 4, putting soil in the crushing and screening system so that the soil can be uniformly mixed with the remediation materials, the liquid material or water for a reaction, and conveying the remediated soil to a maintenance area for maintenance; 5, conducting sampling detection on the remediated soil, and completing remediation when the soil is detected to be qualified. By means of the device andmethod, efficient curing/stabilizing remediation of heavy-metal-polluted soil, solid waste, sludge and other materials can be achieved, and the device and method have a good remediation effect on heavy-metal compound pollution soil.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil remediation, in particular to an intelligent integrated soil remediation equipment and a remediation method. Background technique [0002] my country is nearly 20 years behind developed countries in the research and development of contaminated soil remediation technology. There is still a big gap in remediation technology, equipment and large-scale application, and there is a serious shortage of key remediation equipment. With the vigorous development of the environmental protection industry, more and more attention has been paid to environmental protection equipment. On October 24, 2017, the Ministry of Industry and Information Technology issued the latest "Guiding Opinions on Accelerating the Development of Environmental Protection Equipment Manufacturing Industry", pointing out that the current innovation capability of the environmental protection equipment manufacturing industry is n...

Problems solved by technology

On the one hand, different repair materials are suitable for solidification / stabilization of different heavy metals. For example, Cd and As in soil have an antagonistic effect on repair, and the step-by-step reaction is conducive to the synergistic repair of different heavy metals; on the other hand, different types of repair materials are mixed and stacked. They will react together and affect the repair effect. For example, when lime is mixed with aluminum chloride, magnesium chloride and other materials, it will first generate insoluble substances by itself, which seriously reduces the repair effect of repair materials. Moreover, traditional soil repair equipment has low intelligence and cannot Dosing repair materials step by step
