Problems solved by technology

The groundwater pollution in our country is becoming more and more serious. The strata below the surface are complex and the groundwater flows extremely slowly. Therefore, once the groundwater is polluted, it is very difficult to treat and repair it. Not only does it require a large economic investment, but it also has high technical difficulties, high risks, and a long treatment cycle.
At present, the treatment of groundwater pollution is less

Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0032] like Figure 1-3 As shown, the system for controlling shallow groundwater pollution of the present invention includes an infiltration storehouse 2 built on the site 1 of the groundwater polluted area and a water pump 6 arranged at the bottom of the infiltration storehouse to extract the treated groundwater from the storehouse. 2. The bottom of the reservoir and the slope 3 around the reservoir are covered with a filling medium layer 4. The filling medium layer 4 consists of a limestone gravel layer 10 with a thickness of 15-50 cm from top to bottom, an activated carbon layer 9 with a thickness of 15-50 cm, and a thickness of It is composed of 15-50 cm zeolite and synthetic ion exchange resin layer 8 .

[0033] The slope ratio of the slope 3 of the seepage reservoir is 1:3-1:6, and the elevation of the reservoir bottom is taken as 3-8m be...

Abstract

The invention discloses a system and a method for treatment of shallow groundwater pollution. The system comprises a seepage reservoir which is built at a site in a groundwater contaminated area, anda water pump which is arranged at the bottom of the seepage reservoir and used for pumping treated groundwater out of the seepage reservoir, wherein the bottom of the seepage reservoir and the slope surrounding the seepage reservoir are respectively covered with a filling medium layer which is composed of a limestone gravel layer with a thickness of 15 to 50 cm, an active carbon layer with a thickness of 15 to 50 cm, a zeolite layer with a thickness of 15 to 50 cm and a synthetic ion-exchange resin layer from top to bottom. The construction method comprises the following steps: site selection,seepage reservoir digging, treatment of the slope and a base, medium filling, sediment removal, and underground recharging. The invention has the following advantages: construction is simple; technical difficulty is low; the treatment range of groundwater is broad; the treated groundwater is pumped back to underground, so sustainable circulating utilization of groundwater resources in arid and semi-arid areas can be maintained; and characteristics of high efficiency and economy for treatment of shallow groundwater pollution are achieved.

Description

technical field [0001] The invention relates to the field of groundwater pollution control, in particular to a system for controlling shallow groundwater pollution and a method for controlling shallow groundwater pollution. Background technique [0002] Groundwater pollution mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, resulting in a decline in quality. The groundwater pollution in my country is becoming more and more serious. The strata below the surface are complex and the groundwater flows extremely slowly. Therefore, once the groundwater is polluted, it is very difficult to treat and repair it. Not only is the economic investment large, but also the technical difficulty is high, the risk is high, and the treatment cycle is long. At present, the treatment of groundwater pollution is less carried out. Contents of the invention [0003] The technical pro...
