A groundwater pollution treatment device

Abstract

The invention discloses a groundwater pollution treatment device, which comprises a filter tank, a biochemical reaction tank, an adsorption tower, a pipeline mixer and a bacteria liquid tank. The filter tank is provided with a first filter screen; the biochemical reaction tank is provided with a first guide plate, The second deflector, the third deflector and the fourth deflector, the four deflectors divide the biochemical reaction tank into an aerobic zone, anaerobic zone and anaerobic zone in turn; the first deflector and the second deflector A second filter screen is provided between the deflectors, a third filter screen is provided between the third deflector and the fourth deflector, and the second filter screen and the third filter screen seal the two ends of the aerobic zone; There is a liquid distribution pipe in the tower, and a modified vermiculite adsorption layer and an activated carbon adsorption layer are arranged under the liquid distribution pipe in turn; a liquid inlet pipe is provided above the pipeline mixer, and the liquid inlet end of the liquid inlet pipe is located in the bacterial solution pool. The invention has the advantages of reasonable design, convenient use, high operation efficiency, better treatment effect through various treatment equipments, and ultimately all indexes of the treated groundwater can meet the quality requirements of the groundwater.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a groundwater pollution treatment device. Background technique [0002] With the rapid development of cities, more and more garbage is collected, and there are more and more landfills, and the amount of leachate produced by landfills is also increasing. Leachate is the product of the gravity flow of liquid in the landfill. It mainly comes from precipitation and the water contained in the garbage itself. Most of the existing landfills have not done strict anti-seepage work, causing the leachate to enter the groundwater. Pollution of ground water. Landfill leachate is a kind of high-concentration organic wastewater with complex components. It mainly contains high concentrations of organic matter, ammonia nitrogen and a certain concentration of heavy metal ions. If it is directly discharged into the environment without treatment, it will cause serious environme...
