Embodiment Construction

[0048] The present invention is described in further detail below in conjunction with accompanying drawing:

[0049] The embodiment of the present application provides a contaminated soil leaching treatment equipment, which solves or partially solves the technical problems of low repair efficiency, long cycle, high cost, and poor applicability of soil ectopic leaching devices in the prior art. Set the screening and crushing system, pulping system, soil treatment system and chemical supply system on the crawler roller. The screening and crushing system crushes and screens the polluted soil into small particles of polluted soil with a set particle size, and the pulping system pollutes the small particles. The soil is made into mud, the soil treatment system repairs the mud through the eluent, the chemical supply system supplies the eluent to the soil treatment system, and at the same time supplies the water agent to the pulping system; in this way, convenient operation, reasonabl...

Abstract

The invention relates to contaminated soil treatment equipment through leaching. The contaminated soil treatment equipment comprises a crawler-type road roller, a screening and crushing system, a pulping system, a soil treating system and a medicament feed system; the screening and crushing system is used for breaking hard soil blocks in contaminated soil and screening impurities such as rocks and plastic in the contaminated soil; the pulping system is used for further removing large-particle substances in the contaminated soil, so that the treatment amount of the contaminated soil is reduced, and the treatment cost is reduced; through the adoption of the soil treating system, quick remediation of the contaminated soil through leaching is realized; through the adoption of the medicament feed system, the feed of medicaments and reutilization of a leacheate is realized. All materials and devices are mounted on the crawler-type road roller, so that the transportation and the construction are convenient. The contaminated soil treatment equipment integrates functions of soil excavation, soil screening, medicament adding, soil leaching, leacheate reutilization and automatic control, is compact in structure, convenient to operate and high in suitability and efficiency, is suitable for application of large-scale engineering, and can realize efficient and quick remediation of various contaminated sites.

Description

technical field [0001] The invention relates to the technical field of environmental geotechnical engineering, in particular to a contaminated soil leaching treatment equipment. Background technique [0002] With the development of my country's social economy and the acceleration of urbanization, a large number of legacy polluted land needs to be treated urgently. According to the National Soil Pollution Survey Bulletin released by the Ministry of Environmental Protection in 2014, the overall soil environment situation in the country is not optimistic. Some areas have serious soil pollution, the soil environment quality of cultivated land is worrying, and the soil environment problems of industrial and mining wasteland are prominent. Man-made activities such as industry, mining, agriculture, and high background values ​​of the soil environment are the main causes of soil pollution or exceeding standards. According to statistics, there are about 150 million mu of polluted cu...
