Groundwater well and groundwater treatment system

Abstract

The invention discloses a groundwater treatment system and a groundwater well. The groundwater well comprises a well body, wherein a first stainless steel pipe sheathes outside the well body, the depth of the underground part of the first stainless steel pipe is 30-40m, the upper end of the first stainless steel pipe is higher than a wellhead of the well body, a distance is kept between the lower end of the first stainless steel pipe and the bottom of the well body, a first cement well cementation layer is arranged outside the first stainless steel pipe, a second stainless steel pipe sheathes outside the first cement well cementation layer, the upper end of the second stainless steel pipe is also higher than the wellhead of the well body, the depth of the underground part of the second stainless steel pipe is 5-7m, a second cement well cementation layer is arranged outside the second stainless steel pipe, and the first stainless steel pipe, the first cement well cementation layer, the second stainless steel pipe and the second cement well cementation layer are sealed with the top of the wellhead. National prime-quality drinking water standards can be met without adding an additive or carrying out ozone sterilization, and no bacteria or bromate is contained. Iron and manganese can be effectively removed.

Description

technical field [0001] The invention relates to a groundwater treatment system, and also relates to a groundwater well, which belongs to the field of drinking water treatment. Background technique [0002] At present, the treatment technology of drinking water sterilization and removal of iron and manganese mainly adopts ozone technology, such as the treatment process of DOHNE water plant in Munich, Germany: [0003] Well water or river water goes through pre-ozone, coagulation, sedimentation, ozone contact tank, filtration, bioactive rock, and then adds ammonium oxide and disinfection to obtain the product. [0004] At present, the domestic packaged drinking water industry uses this process. [0005] However, due to the intervention of ozone, a new substance, bromate, is produced in drinking water, and bromate is easy to decompose when heated. Bromate is recognized internationally as a potential carcinogen of Class 2B, which is a by-product produced after water sources su...

AI Technical Summary

Problems solved by technology

[0009] In the past hundred years, the mechanism and engineering of iron and manganese removal in drinking water have been a hot research topic that is difficult to break through. At present, there is no case in the world's packaged drinking water industry that has completely and stably reached the industry standard through the medium.
