Description

Background
Groundwater, is water stored in the voids of the formation, including rock pores, fractures and vugs, below the gas-filled zone. Groundwater is one of the most prominent and widely distributed water resources on earth. Over 15 million people worldwide rely primarily on groundwater as drinking water. In 2008, the total water supply of China is 5910 hundred million m < 3 >, wherein the water supply of underground water sources accounts for 18.3%. More than 400 cities in China mine underground water, the proportion of the underground water used in the cities in the North China and the northwest China is respectively up to 72 percent and 66 percent, and the underground water is often the only water supply source in partial cities and rural areas. Underground water is an irreplaceable important resource necessary for the economic and social development of China and the life of people.
In the plain areas with dense population, large interference on human activities and developed industrial and agricultural production in China for 20 years, underground water is increasingly polluted due to the discharge of industrial wastewater and domestic sewage, the use of large-area and excessive chemical fertilizers and pesticides, the leaching of garbage dumps, the leakage of underground oil tanks and the like. According to the investigation of shallow groundwater of 118 major cities across the country, 97.5% of cities are polluted to different degrees, and 40% of cities are seriously polluted. In shallow groundwater in 197 km2 plain area evaluated by national water resource survey, the areas of the I type and II type water quality areas are only 4.98 percent of the total flow area, the III type area is 35.53 percent, and the IV type and V type areas are as high as 59.49 percent. Groundwater pollution is the most serious in rivers such as Taihu lake, liaohe, sea river and Huaihe river, and the areas of water quality areas inferior to III-class water quality account for 91.49%,84.55%,76.40% and 67.78% of the areas of the corresponding rivers. Water quality type water shortage caused by groundwater pollution becomes an important restriction factor for national economy and social development. Therefore, researches on underground water protection means, pollution control methods and the like are currently the problems to be solved urgently.
The small-sized underground water seepage physical model is a model which is constructed by using a water-resisting material and a water-containing medium and can simulate the movement of underground water in a water-bearing stratum and the evolution of water quality, and is one of main means for researching the movement rule of underground water flow and the solute transfer rule.
When a small underground water seepage physical model is used for researching the solute transport or the related aspects of underground water pollution control, waste liquid discharged by the model possibly contains harmful components, and if the research relates to volatile solutes, the seepage model can discharge a certain amount of waste gas. In order to avoid the harm caused by the waste liquid and the waste gas, the waste liquid and the waste gas need to be subjected to harmless treatment, or the waste liquid and the waste gas are collected and then treated to realize the aim of harmless treatment.
For the waste liquid containing volatile solute, the sealing performance of the existing collection technology is poor, the waste liquid still contains more volatile solute, the environment is polluted, and the harm to human bodies is great.
