Ultrafiltration reverse-osmosis water purification treatment system

Abstract

The invention relates to an ultrafiltration reverse-osmosis water purification treatment system. The ultrafiltration reverse-osmosis water purification treatment system comprises a raw water tank, a sand filter water intake high-pressure pump, a sand filter, an activated charcoal filter water intake high-pressure pump, an activated charcoal filter, a first reverse osmosis filter water intake high-pressure pump, a first reverse osmosis filter and a purified water tank which are connected together sequentially, wherein the raw water tank is provided with an ultraviolet lamp; the sand filter comprises a tank body which is provided with a grille plate and a sand filtering layer stacked on the grille plate, the tank body is partitioned into a sand filter part water outlet chamber and a sand filter part water inlet chamber by the sand filtering layer, the sand filter part water outlet chamber is provided with a sand filter part water outlet pipe orifice which is connected together with the activated charcoal filter water intake high-pressure pump, and the sand filter part water inlet chamber is provided with a sand filter part water inlet pipe orifice which is connected together with thesand filter water intake high-pressure pump. The ultrafiltration reverse-osmosis water purification treatment system has the advantages that purified water is few in viable bacteria and the sand filter is good in water flow smoothness, and the problems of the existing water purification treatment process that the purified water is large in quantity of viable bacteria and the sand filter is poor in water flow smoothness are solved.

Description

technical field

[0001] The invention relates to the technical field of pure water treatment, in particular to an ultrafiltration reverse osmosis water purification treatment system. Background technique

[0002] The process of pure water production through ultrafiltration and reverse osmosis first needs to be filtered through a sand filter and an activated carbon filter, and then filtered through a reverse osmosis filter to form pure water, which is stored in a pure water tank When output to the water point, it is sterilized and then filtered. The existing pure water production equipment has the following disadvantages when producing pure water: the bacteria in the raw water have a high probability of reaching the pure water tank alive, which leads to an increase in the amount of bacteria in the pure water output from the pure water tank, and the increase in bacteria species will lead to pure water. The service life of the filter that is filtered after water sterilization i...
