Problems solved by technology

However, under conditions such as sudden natural disasters, when the daily water supply system is damaged and cannot work normally, people's drinking water safety will be seriously threatened
Especially when disasters occur and secondary disasters occur, chemical plants, nuclear power plants, biological product companies and other industries in the disaster area may leak accidents, resulting in serious secondary disaster pollution of water sources. There may be substances similar to chemical warfare agents, Radioactive warfare agents and pollutants of unknown biological contamination, Hurricane Katrina in the United States and the Fukushima earthquake in Japan caused serious secondary disasters, resulting in serious chemical and nuclear pollution of water sources, causing serious damage to rescue workers and affected people drinking water safety poses a serious threat
[0003] At present, there are many field drinking water purification and disinfection technologies and equipment available in the market, mainly for the purpose of processing conventional water source water in the field to obtain drinking water, mainly using membrane filtration technology of various materials, which is harmful to chemical, radioactive, etc. The removal effect is limited, and it cannot meet the needs of people to deal with chemical, radioactive and biological pollution of water sources

Abstract

The invention provides a multifunctional field drinking water purification and disinfection device and an application method thereof and belongs to the technical field of drinking water purification and disinfection. The multifunctional field drinking water purification and disinfection device comprises a backpack, a water treatment device, a water treatment reagent and a water quality analysis instrument. According to the multifunctional field drinking water purification and disinfection device, excessive disinfectant is used for disinfecting field drinking water, and the oxidation and inactivation of chemical, biological and radioactive pollutants are realized by removing the excessive disinfectant through a dechlorinating agent; the removal of turbidity substances and chemical, biological and radioactive pollutants is achieved through coagulation and precipitation; active carbon and ion exchange resin are used as main adsorption materials, and chemical, biological and radioactive pollutants are removed through adsorption. According to the multifunctional field drinking water purification and disinfection device, the quality of treated water is detected by using the water qualityanalysis instrument so that the drinking safety of the purified water can be ensured. Meanwhile, the invention provides the application method of the disinfection device. The method is simple to operate and capable of rapidly obtaining large-volume safe drinking water.

Description

technical field [0001] The invention relates to the technical field of drinking water purification and disinfection, in particular to a multifunctional field drinking water purification and disinfection equipment and an application method thereof. Background technique [0002] Safe drinking water is one of the important material bases for maintaining life systems. At present, municipal water supply can basically meet people's daily needs. However, under conditions such as sudden natural disasters, when the daily water supply system is damaged and cannot work normally, people's drinking water safety will be seriously threatened. Especially when disasters occur and secondary disasters occur, chemical plants, nuclear power plants, biological products companies and other industries in the disaster area may leak accidents, resulting in serious pollution of secondary disasters to water sources. There may be substances similar to chemical warfare agents, Radioactive warfare agent...
