Problems solved by technology

However, due to the long water production time and small water volume of the water purifier using the nanofiltration membrane or reverse osmosis membrane filter element, it is difficult to meet the requirements of rapid and large water supply, and the nanofiltration membrane or reverse osmosis membrane filter element is used, as well as the ultraviolet germicidal lamp device. The water purifier cannot operate due to the lack of mains power in the wild environment
Therefore, in the harsh environment in the wild, the existing water purifier without mains power supply cannot guarantee the safety of the direct drinking water, so that it cannot be used in the environment of natural disasters such as earthquakes, floods, and droughts.
The above-mentioned defects and deficiencies affect the popularization of water purifiers

Embodiment Construction

[0024] The attached drawings show the preferred embodiment of the invention. The water storage bag 1 and the primary coarse fiber melt-blown tubular filter element 21 of the filter element unit 2 are flexibly and tightly connected by a hose; the second stage pre-filter element of the filter element unit is a composite filter element 22 composed of activated carbon filter material and fine fiber melt-blown tubular filter element. KDF filter material can be placed in the tubular fiber meltblown filter element. The third-stage fine filter element 23 adopts an ultrafiltration membrane filter element. The ultraviolet sterilizer 6 made up of an ultraviolet germicidal lamp 61 and a quartz sleeve 62 is connected in the direct drinking water outlet pipeline. The water filtered by the fine filter element 23 enters the ultraviolet sterilizer 6, and the ultraviolet sterilizing lamp 61 emits ultraviolet light under the excitation of the electronic rectifier, and passes through the quartz ...

Abstract

The invention relates to the industry of water treatment, in particular to the depth-type filtration and purification of field drinking water. The invention discloses a method for filtering field water for drinking. Equipment for implementing the method comprises a filter element unit for filtration, a water pump device for pumping raw water, a germicidal lamp for sterilizing bacteria and viruses and a noncommercial power supply device, wherein the output circuit of the power supply device is connected with the germicidal lamp and the control circuit of the water pump device; the water pump device is connected to a raw water filtration and sterilization pipe formed by the filter element unit and an ultraviolet ray sterilizer. The equipment has the advantages of simple structure, convenient use, diversified water resources and capability for pretreatment, strong field environment suitability, applicability to emergency environments where accidents of natural disasters such as earthquake, flood, drought and the like occur, and contribution to the popularization and promotion of water purifiers.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of outdoor drinking water. Background technique [0002] At present, the use of water purifiers has been popularized to a certain extent in China. In the field environment, when raw water such as lake water, rainwater, river water, and groundwater is directly filtered into drinking water, the water purifier is used to filter impurities in the water in depth, which better protects the health of users. However, along with the gradual popularization of portable water purifiers, their defects and deficiencies in application have gradually been exposed. Due to the diversity and unpredictability of the natural environment in the wild, as well as suspended pollutants such as bacteria, algae, insects, and dust, as well as particles and colloids in the water, the water quality index is often lower than that of tap water. Pressure water purif...
