Household drinking water purification technique and facility

Abstract

The invention relates to a household drinking water purification technique and facility. The facility comprises a pretreater, a water accumulator, a membrane filter and a minitype circulating pump which are sequentially connected in series, wherein the pretreater is connected with an incoming water tube valve; the pretreater comprises a heater; the membrane filter comprises a high-temperature-resistant filter; and the membrane filter is provided with a permeation side valve and an effluent water valve. The technique comprises the following steps: pretreatment stage: the heater heats the incoming water, and the heated water enters the water accumulator; and advanced treatment stage: the heated incoming water flows into the membrane filter and is purified by the high-temperature-resistant filter membrane, and the permeation side valve is opened to obtain the filtered drinking water. The pretreater is utilized to heat the incoming water, the membrane filter is utilized to eliminate the suspended solids and harmful substances generated in the heating process, and the incoming water is heated to enhance the membrane permeation rate and perform sterilization.

Description

technical field [0001] The invention relates to a drinking water purification process and equipment, in particular to a household drinking water purification process and equipment. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, people have higher and higher requirements for drinking water and water quality. The shortage of water resources has become a problem that must be paid attention to in today's society, and the emergence of water purification equipment is gradually The water quality problem has been alleviated, but the existing water purification devices mainly include ultrafiltration, nanofiltration, reverse osmosis and various filter media filters. The filter media filter is generally used as the front of other high-precision filters due to its low filtration accuracy.

[0002] With the development of the economy and the continuous improvement of people's living standards, people have higher and higher requirements for drinking water and water quality. The shortage of water resources has become a problem that must be paid attention to in today's society, and the emergence of water purification equipment is gradually The water quality problem has been alleviated, but the existing water purification devices mainly include ultrafiltration, nanofiltration, reverse osmosis and various filter media filters. The filter media filter is generally used as the front of other high-precision filters due to its low filtration accuracy. Filters play the role of pre-treatment; reverse osmosis can intercept minerals, and the long-term drinking of pure water produced is not good for health; although ultrafiltration and nanofiltration can intercept most suspended solids and most organic macromolecules in water, but Almost no interception capacity for ions

In addition, for normal temperature water filtration, the filter has disadvantages such as low penetration of permeated water caused by incomplete cleaning, and easy breeding of bacteria inside the filter element.
