Groundwater wells and groundwater treatment systems

Abstract

The invention discloses a groundwater treatment system and a groundwater well, wherein the groundwater well comprises a well body, and a first stainless steel pipe is sheathed on the well body, and the depth of the first stainless steel pipe is 30-40m underground, and the first stainless steel pipe is The upper end is higher than the well head of the well body, and there is a distance between the lower end and the well bottom of the well body. The first cement cementing layer is set outside the first stainless steel pipe, and the second stainless steel pipe is covered with the first cement cementing layer. The upper end of the second stainless steel pipe is also higher than the wellhead of the well body, and its underground depth is 5-7m. The second layer of cement well cementing layer is set outside the second stainless steel pipe. The first stainless steel pipe, the first layer of cement well cementing layer, The second stainless steel pipe, the second layer of cement cementing layer and the top of the wellhead are sealed. Without adding any additives, without ozone sterilization, it can meet the national high-quality drinking water standard, without any bacteria and bromate. Can effectively remove iron and manganese.

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.
