Soil pollutant removal treatment system

Abstract

The invention relates to the field of soil purification. The invention relates to a soil pollutant removal treatment system. The system comprises a heat-preservation room, a treatment pond and a reservoir, a permeable top plate is arranged in the treatment tank, a lower layer is a diving layer, a heating device is arranged at the bottom of the diving layer, an inverted V-shaped sealing cover is arranged at the top of the treatment tank, an exhaust pipe is arranged right above the inverted V-shaped sealing cover, the other end is connected with the reservoir through a condenser pipe, a water outlet pipe is arranged on the upper-layer side wall of the treatment tank, a water inlet pipe is arranged on the lower-layer side wall of the treatment tank, a water return pipe is arranged below the water inlet pipe, an air extracting pump and a purifier are respectively arranged on each one of the exhaust pipe, the water outlet pipe and the water return pipe, and an air extracting pump is arranged on the water inlet pipe. The design of the invention mainly aims at removing movable pollutants, especially metal element pollutants, and the more serious the soil pollution is, the better the removal effect is, so that the effects of centralized treatment on pollutants in soil, recycling of pollution elements, energy conservation and emission reduction can be achieved.

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.
