Drinking water defluorination purification treatment process and equipment

Abstract

The invention discloses a drinking water defluorination purification treatment process and equipment. The equipment comprises a raw water pump, a pretreatment device, an ultrafiltration device, a booster pump, a cartridge filter, a high-pressure pump, a reverse osmosis device, a finished product water tank, a disinfection device, an external water supply pump and a concentrated water collector. The ultrafiltration device is formed by connecting a plurality of ultrafiltration membrane assemblies in parallel. The reverse osmosis device is composed of a plurality of reverse osmosis membrane assemblies which are connected in series and in parallel to form one stage, two stages or more stages. The concentrated water collector is connected with a domestic miscellaneous water pipeline or a reclaimed water pipeline and can be used for environmental sanitation and cleaning. Fluoride in water can be removed under the condition that no chemical agent is added, meanwhile, deep purification treatment on drinking water is achieved, the problem that fluorine in the drinking water exceeds the standard is effectively solved, and safety and sanitation of the drinking water are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a drinking water defluorination purification treatment process and equipment. Background technique [0002] Fluorine is an element that exists widely in nature and is one of the essential trace elements for the human body. However, excessive intake of fluorine can lead to many diseases. Long-term drinking of drinking water with excessive fluoride will lead to dental fluorosis, skeletal fluorosis and other diseases. my country's "Drinking Water Sanitation Standard" (GB5749-2006) clearly stipulates that the content of fluoride in drinking water should not exceed 1.0 mg / L. However, in many areas of my country, especially in agricultural and pastoral areas, there is a widespread problem of excessive fluorine in drinking water. Therefore, the development of high-efficiency drinking water defluoridation purification process and equipment is of great significance t...

AI Technical Summary

Problems solved by technology

[0004] However, most of the existing membrane separation drinking water purification processes have imperfect pretreatment procedures and low removal rates of pollutants in water, especially in the drinking water defluorination process, because the core membrane element Easy to be polluted, resulting in short service life of membrane elements and poor purification effect of product water
