Vehicle-mounted repairing equipment and method for polluted site soil and underground water body

Abstract

The invention provides vehicle-mounted repairing equipment for polluted site soil and underground water body, which comprises a dry powder hopper, a level meter, a feeding motor, a stirring machine, a mixing tank, a liquid level meter, a flowmeter, a magnetic valve, a tap water pipe, a liquid preparation feeding pipe, an eclectic cabinet, a touch screen operating system, an alarm, a plunger pump, a mixed liquid output pipe and a pressure meter. A repairing method comprises the steps of: adding a solid preparation into the dry powder hopper, adding the preparation into the mixing tank by using the feeding motor, introducing water or other solvent through a water inlet pipe, stirring by using the stirring machine to ensure that the solid preparation is fully dissolved in water or other solvents to prepare a repairing preparation with required concentration; or directly adding a liquid preparation into the mixing tank, introducing the water or other solvents through the water inlet pipe to ensure that the liquid preparation is diluted into the repairing preparation with the required concentration. Through automatically or manually starting the plunger pump, the repairing preparation is pressurized and injected into a polluted medium through the mixed liquid output pipe and reacts with pollutants in the medium, thus the purpose of efficient repairing is achieved.

Description

technical field [0001] The invention relates to technical equipment for soil / water restoration in polluted sites, and belongs to the field of environmental protection equipment. Background technique [0002] At present, due to the impact of the rapid development of industry, agriculture, energy, transportation and other industries, the area of ​​polluted soil / groundwater in my country is increasing day by day, which has caused serious harm to the ecological system and human health. With the advancement of suburbanization and anti-urbanization, a large number of urban enterprises have relocated. In 2008, the number of enterprises shut down and transferred in my country reached 22,488. Phenomena such as leakage and leakage” and various environmental accidents will cause pollutants to enter the soil and groundwater of the site (Document 1: Liao Xiaoyong et al. Urban industrial polluted sites: a new topic in the field of China’s polluted environment restoration. Environmental Sci...

Problems solved by technology

Chinese patent 200710026561.9 mentions the use of zero-valent iron to accelerate the reduction and degradation of organic pollutants in soil. It is also obtained through column experiment simulation that this method is suitable for in-situ remediation of heavily organically polluted soil, and does not mention the actual pollution. Site, how to inject restoration agents such as zero-valent iron into the environmental medium to be restored

Chinese patent 200710069637.6 mentions injecting potassium permanganate solution into polluted soil and groundwater to remove explosive pollutants in interception area and polluted area through chemical oxidation, but does not introduce specific injection equipment and methods

[0005] At present, my country's contaminated site remediation equipment, including soil gas extraction, chemical oxidation, thermal desorption, leaching and other remediation equipment, mostly stays in the stage of scientific research equipment development or experimental prototype pilot test, and the industrial application of remediation equipment is seldom

Countries such as Europe and the United States have developed a lot of advanced repair equipment, but the price is extremely expensive, and it is not necessarily suitable for application in our country
