Description

Technical Field

[0001] The utility model relates to the technical field of emergency treatment of water source pollution. Specifically, it relates to an emergency treatment device for sudden organic pollutant pollution of drinking water sources. Background Art

[0002] For organic pollution of water sources, the most commonly used method is the extraction treatment technology. A certain number of pumping wells are arranged in the polluted site, and the polluted groundwater is pumped up through water pumps and wells. Then, it is treated on the ground and enters the buffer pool. The treated groundwater is discharged into the surface runoff and recharged into the ground or used for local drinking water supply. The organic volatile gases blown out are adsorbed by activated carbon and then discharged into the air. However, this method has a large floor area for equipment, high investment costs, low efficiency, and cannot cope with sudden pollution situations. There is a need to develop a small-sized treatment device with low investment and high treatment efficiency.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number CN202122158077.X discloses an emergency treatment device for sudden organic pollutant pollution of drinking water sources, including a treatment tank. A number of guide plates are fixedly connected inside the treatment tank. A cavity is provided inside the guide plate. A number of filters are provided on one side of the cavity. A filter nozzle is provided on one side of the treatment tank. An installation groove is provided on the inner wall of the filter nozzle. A first filter plate is slidably connected inside the installation groove. A second filter plate is provided on one side of the first filter plate. A rotating shaft is rotatably connected to the middle of the first filter plate. A turbine blade is fixedly connected to the outer side of one end of the rotating shaft. A rotating rod is fixedly connected to the other end of the rotating shaft. Rotating plates are fixedly connected to both ends of the rotating rod. This utility model can filter the water source multiple times by setting the filter nozzle. At the same time, by setting the guide plate and filter inside the treatment tank, the water source can be disinfected to achieve the purpose of emergency treatment of the water source. However, there are still the following defects:

[0004] (1) In the prior art, the emergency treatment device sterilizes the sewage through ozone, but the ozone release area is small, resulting in a small contact range with the sewage, and the sterilization effect is poor.
