A soil pollutant removal treatment system

Abstract

The invention relates to the field of soil purification, in particular to a soil pollutant removal and treatment system, which includes a heat preservation room, a treatment pool and a water storage tank. A permeable roof is arranged in the treatment pool, the lower layer is a submerged layer, and a heating device is provided at the bottom of the submerged layer. , the top of the treatment tank is provided with an inverted "V"-shaped sealing cover and a suction pipe is provided directly above it, and the other end is connected to the reservoir through a condensation pipe. A water inlet pipe is arranged on the side wall, a water return pipe is arranged under the water inlet pipe, an air suction pump and a purifier are respectively arranged on the air suction pipe, the water outlet pipe and the water return pipe, and an air suction pump is arranged on the water inlet pipe. The design of the present invention is mainly aimed at The removal of mobile pollutants, especially metal element pollutants, and the more serious the soil pollution, the better the removal effect, which can achieve the centralized treatment of pollutants in the soil, the recycling of polluted elements, and the effects of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the field of soil purification, in particular to a soil pollutant removal treatment system. Background technique [0002] In recent years, with the continuous deepening of my country's industrialization, urbanization, and rural intensification, the social economy has been continuously developed, but at the same time, the wanton use of various energy and resources, the random discharge of industrial "three wastes", urban construction waste, Unreasonable stacking of household garbage, exhaust emissions from vehicles, and application of chemical fertilizers and pesticides in rural areas have caused soil pollution problems to become more and more serious. The worsening of soil pollution and the non-renewable nature of soil have become a major problem that seriously restricts the sustainable development of our country. Solving the problem of soil pollution has become an urgent need for my country's economic development. Currently, th...

Problems solved by technology

This type of method has good treatment effect, low treatment cost, and will not cause secondary pollution, but the repair rate is slow, and it takes a long time to reach the control level

[0006] Therefore, although most of the above methods have been applied in practice, there are still many problems such as high equipment cost, poor effect, and secondary pollution.

However, these methods provide a wealth of theoretical guidance in dealing with soil pollution. Based on the above background, it is necessary to design a treatment system that can effectively remove soil pollutants, which can effectively solve the problems of high cost and low decontamination efficiency.
