Vehicle-mounted emergency disinfection and purification device for drinking water in disaster environment

Abstract

The invention relates to a vehicle-mounted emergency disinfection and purification device for drinking water in disaster environment, belongs to the technical field of gas discharge application and drinking water security control, and is technically characterized in that: on the basis of a narrow-gap dielectric barrier electric filed discharge reactor, a wide-gap dielectric barrier discharge reactor is additionally arranged to establish an oxygen active particle non-equilibrium plasma generation system, a two-stage gas-liquid efficient miscibility mode of a miscible booster pump and a venturigas-liquid miscible device is adopted to strengthen a chain reaction process that oxygen active particles form hydroxyl radicals, a plugboard disinfection and sterilization tank is adopted to extend a drinking water flowing line so as to prolong the disinfection and sterilization time of the drinking water, and the device can be integrally arranged on a steel bottom platform of an automobile so as to be convenient for transportation. The invention has the beneficial effects that: in the disaster environment, the disinfection and sterilization of the drinking water are improved, and the safetyand emergency supply of the drinking water are increased.

Description

technical field [0001] The invention belongs to the field of gas discharge application technology and drinking water safety assurance technology, and relates to a vehicle-mounted mobile drinking water treatment system, in particular to a vehicle-mounted drinking water emergency disinfection and purification device in a disaster environment. Background technique [0002] my country is a country where natural disasters and biochemical disasters frequently occur, and health emergencies also occur from time to time. In disaster-occurring areas, water sources are often seriously polluted, and water supply systems are also severely damaged, making it difficult to guarantee drinking water. Not only that, with the rapid development of my country's industry and the acceleration of urbanization, a large amount of industrial and domestic sewage is directly discharged into the receiving water body, resulting in the pollution of 82% of water areas and 93% of urban drinking water sources, ...

AI Technical Summary

Problems solved by technology

The existing problems are long disinfection and sterilization time, large dosage, strong selectivity, residual chlorine organic pollutants after biochemical reaction, such as chloroform and haloacetic acid, etc.

But this method also has some problems: the process of only using ozone to decompose in water to trigger free radical chain reaction to generate hydroxyl radicals is unstable, and is greatly affected by the water quality; the cavitation of the jet is very conducive to improving the solubility of gas in water , but for the generation of hydroxyl radical initiator HO 2 - The promoting effect is limited, and the concentration of hydroxyl radicals produced is not ideal; the chain reaction of hydroxyl radicals will cause partial chain reaction interruption during the secondary mixing process of the main pipeline, which reduces the efficiency of drinking water disinfection and sterilization
