Description

Technical Field

[0001] The utility model relates to the technical field of groundwater prevention and control, in particular to a device for preventing and controlling urban groundwater pollution. Background Art

[0002] Groundwater refers to the water stored in the rock voids below the ground surface. Narrowly speaking, it refers to the water in the saturated aquifer below the groundwater table. Groundwater is an important part of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industrial and mining, and cities. However, under certain conditions, changes in groundwater can also cause adverse natural phenomena such as waterlogging, salinization, landslides, and land subsidence.

[0003] After groundwater is polluted, the quality of urban water supply drops significantly. Regarding how to prevent and control urban groundwater pollution, various prevention and control devices emerge in an endless stream. When the existing groundwater prevention and control devices are in use, floating flocs and sundries in the water cannot be effectively cleaned. Some devices can filter them, but after long-term use, the filter screen will be blocked, resulting in poor filtering effect and low groundwater passing rate, affecting normal purification operations.

[0004] Therefore, it is necessary to provide a device for preventing and controlling urban groundwater pollution to solve the above problems. Content of the Utility Model
