Water purifying column for water dispenser

Abstract

The invention belongs to the field of purified water, and particularly relates to a water purifying column for a water dispenser. The water purifying column comprises a housing, a water inlet, a wateroutlet, an ultraviolet lamp tube, a partition board and fillings, wherein the water inlet and the water outlet are formed in the housing; the ultraviolet lamp pipe is arranged in the housing; the partition board is used for fixing the ultraviolet lamp tube; the fillings are arranged in the housing and are used for filtering water; the fillings comprise a modified carrier and active silver ions loaded on the modified carrier; the modified carrier is a carrier which is modified on the surface of the porous carrier through tetrabutyl titanate and a silane coupling agent; the using amount of thetetrabutyl titanate is 0.1-5% of the mass of the porous carrier; the using amount of the silane coupling agent is 0.1-1% of the mass of the porous carrier; the using amount of the active silver ions is 0.1-5% of the mass of the porous carrier. According to the water purifying column disclosed by the application of the invention, heavy metal ions in the fillings are reduced by photoproduced electrons on the surfaces of TiO2, and active silver ions deposed on the surfaces of the porous carrier are used for killing bacteria and hazardous substances in the water, so that running water can be directly drunk.

Description

technical field [0001] The invention belongs to the field of water purification, and in particular relates to a water purification column for a water dispenser. Background technique [0002] With the development of the country's economy, people's requirements for the quality of life are gradually improving, and drinking water safety is getting more and more attention. Therefore, drinking water dispensers from the pipe network of waterworks are widely used. Daily water dispensers mostly use bottled water sources. They have passed strict quality inspections when they leave the factory, and they can be guaranteed for about three months without opening, thus ensuring the safety of regular drinking requirements. But once opened, since the water dispenser will continue to inhale air to replenish during the process of discharging water, bacteria in the atmosphere will follow and mix into the tank of the water dispenser to form pollution, and the maintenance time of purified water q...

Problems solved by technology

In addition, bacteria can multiply rapidly by eating organic matter attached to the surface of activated carbon and filter membranes, endangering human health

Because TiO2 photocatalytic drinking water is a new purification method, it can decompose organic matter in water into CO2 and water, and reduce and remove heavy metal ions in water without secondary pollution. However, due to the low content of organic matter in tap water, water The residence time in the purification column is short, the photocatalytic efficiency is low, and it is difficult to make the water quality after treatment reach the standard for direct drinking
