A continuous reverberation ultrasonic field coupling chemical method drinking water safety treatment device and method

Abstract

The invention discloses a continuous reverberation ultrasonic field coupling chemical drinking water safety treatment device and a continuous reverberation ultrasonic field coupling chemical drinking water safety treatment method. The device comprises main equipment such as a raw water storage tank, a dispensing tank, a chemical reaction kettle with an ejector, a reverberation ultrasonic reactor and a pure water storage tank. The treatment process has the characteristics of I: premixing a chemical agent in the dispensing tank and raw water in a centrifugal pump, causing the mixture to enter the chemical reaction kettle for mixing and reaction through the ejector, and causing the mixture to enter the reverberation ultrasonic reactor for ultrasonic sterilization and organic matter degradation and II: causing the raw water from the raw water storage tank to enter the reverberation ultrasonic reactor for primary sterilization through the centrifugal pump, premixing water discharged from the ultrasonic reactor and the chemical agent from the dispensing tank in the centrifugal pump, and causing the mixture to enter the chemical reaction kettle for complete mixing and sterilization through the ejector. According to the device and the method, a continuous reverberation ultrasonic field is coupled on the basis of a conventional chemical drinking water treatment process, so that the using amount of the chemical agent is reduced, harmful byproducts produced by chemical sterilization are effectively reduced, a sterilization effect is improved, and energy consumption is lowered.

Description

technical field [0001] The invention relates to the field of drinking water treatment, in particular to a continuous reverberation ultrasonic field coupling chemical method drinking water safety treatment device and method. Background technique [0002] With the untreated discharge of large quantities of industrial pollutants, agricultural pollutants, and domestic pollutants, the pollution of groundwater and surface water in my country has become increasingly serious, resulting in serious water pollution in drinking water sources. The traditional sterilization equipment and process of drinking water treatment plants have been difficult to ensure that the effluent fully meets the requirements of my country's drinking water hygiene standards (GB5749-2006), posing a threat to the drinking water safety of urban and rural residents. At the same time, with the continuous improvement of people's quality of life, the requirements for drinking water are also getting higher and higher...
