Abstract

The invention provides a pretreatment device for domestic drinking water, and relates to the technical field of drinking water purification devices. The pretreatment device comprises a water inlet pipe, an activated carbon pipe, a reverse osmosis membrane and ultrafiltration membrane combined pipe, an activated carbon and ultraviolet combined pipe and a water outlet pipe which are sequentially connected, wherein the front end of the water inlet pipe is provided with a water inlet pump and a water inlet stop valve; a sealing ring is arranged between the activated carbon pipe and the reverse osmosis membrane and ultrafiltration membrane combined pipe; the bottom of the reverse osmosis membrane and ultrafiltration membrane combined pipe is provided with an overflow hole; and a water outlet end of the water outlet pipe is respectively provided with a back-flushing pump and a back-flushing stop valve. The pretreatment device is simple in structure, small in volume, convenient to move, simple and easy to operate and rapid in treatment.

Description

[0001] technical field [0002] The invention relates to the technical field of drinking water purification devices. [0003] Background technique [0004] At present, the safety of tap water use has attracted more and more people's attention, and the safety of drinking water in many areas is also threatened to a certain extent. Especially in areas with high hardness of drinking water and some areas with relatively backward water treatment. Through this device for filtration, the device can remove calcium and magnesium ions and harmful bacteria in water to a certain extent through the effective combination of reverse osmosis membrane and ultrafiltration membrane, so as to achieve the purpose of safe drinking water and reach the safety level of drinking water. The device is simple and convenient to use, has strong operability, can meet the needs of different regions, and can be disassembled, assembled, and replaced with internal components to ensure the efficiency of the de...
