Household water purifier

Abstract

The household water purifying installation comprises: a body (1) with inlet and outlet connected to inlet pipe (3) and outlet pipe (4) respectively, a medium (2) in the body (1), an ultrasonic transducer (5) send out 60-300KHz ultrasonic wave and acted on said medium (2), and a power and control system (6). Wherein, the unpurified water flows across the medium (2) through inlet pipe (3) for treatment and flows out from the outlet pipe (4); the transducer (5) ultrasonic cleans the medium at fixed time to restrain the bacteria growth on medium surface. This invention can ensure the fresh and super quality of outlet water.

Description

technical field [0001] The invention relates to a water quality treatment method, in particular to a water quality treatment method using a household water purification device. Background technique [0002] Water resources are the basic material for human beings to survive. With the improvement of living standards and the increasing concern for health, people have higher and higher requirements for the quality of household water. Tap water has been unable to meet people's requirements for drinking water, so bottled water has developed rapidly. In just over ten years, my country's bottled water market has grown from nothing to an industry with an annual output value of hundreds of millions of yuan, and it is still growing at a high speed. However, bottled water suffers from two serious drawbacks. One is that bottled water is easily polluted during production, transportation, and use, and final consumers do not have sufficient technology to monitor, prevent, and eliminate po...

AI Technical Summary

Problems solved by technology

The formation of biofilm is basically inevitable, and the activity of microorganisms may increase the bacterial content, turbidity, and bacterial secretions of the effluent, and deteriorate the water quality.

image 3 That is, after 20 days of operation of a certain brand of water purification device, the growth of bacteria on the surface of the medium is magnified by a microscope at 640 times. These bacteria block the pores on the surface of the medium and reduce the treatment effect; they secrete extracellular substances and pollute the water quality; This increases the bacterial content in the effluent water; more importantly, it is psychologically difficult for users to accept the growth of bacterial film in the direct drinking water device

And traditional various types of fungicides cannot be used for drinking water due to their biological toxicity

Water plants usually use air-water recoil to clean the media, but in the domestic drinking water system, the cleaning of activated carbon and other media has become a major problem. In the case of poor tap water quality, the media will be polluted quickly, and its purification function Reduce or even disappear, thus deteriorating the quality of effluent water, far from meeting drinking water requirements, and posing a potential threat to people's health
