Treatment system for antibiotics in hydroxyl free radical mineralized drinking water and treatment method thereof

Abstract

The invention discloses a treatment system for antibiotics in hydroxyl free radical mineralized drinking water and a treatment method thereof, and relates to the antibiotics in the drinking water. Thetreatment system is provided with a hydroxyl free radical mineralized antibiotics unit, a sodium hypochlorite sterilizing unit, a central control system, a coagulative precipitation tank, a sand filter pool, a clean water pool, a water quality online monitor, a total oxidizing agent water quality online monitor, a residual chlorine online monitor, a sodium hypochlorite storage tank, a mechanicalpump, a controller, a water flowmeter, a magnetic valve and a unit water outlet valve. The hydroxyl free radical mineralized antibiotics unit is formed by a *OH mineralized antibiotics device and a high-throughput liquid-liquid mixing and dissolving hydrodynamic cavitation device. The *OH mineralized antibiotics device is provided with an atmosphere pressure ionic discharge oxygen plasma integration source, a subsection excitation-type high-frequency high-voltage power source, a venturi gas-liquid mixing and dissolving device, a booster pump, a pressure reducing buffer, a bag-type filter and acooling water circulation device.

Description

technical field [0001] The invention relates to antibiotics in drinking water, in particular to a treatment system and a treatment method for antibiotics in drinking water mineralized by hydroxyl radicals. Background technique [0002] my country is a big country in the production and use of antibiotics, with an annual output of about 210,000 tons, which has played a huge role in the treatment, prevention and growth promotion of animal diseases. Antibiotics taken by animals or humans cannot be fully absorbed, and up to 80% to 90% of antibiotics are discharged into the environment through urine and feces in the form of mothers, leading to the generation and spread of antibiotic resistant strains and antibiotic resistance genes (ARGs), It will cause serious environmental pollution problems, and ultimately seriously endanger human health and ecological environment safety. [0003] A large number of antibiotics actually enter the environmental surface water through domestic sew...

AI Technical Summary

Problems solved by technology

[0005] A comprehensive analysis of the above antibiotic removal methods for drinking water found that: the adsorption process is simple and will not cause secondary pollution, but due to the low adsorption capacity, the antibiotic removal effect is not good and the treatment rate is low; the membrane treatment technology cannot destroy the antibiotics, and the discharged concentrate It is not easy to handle, and has the disadvantages of high energy consumption and limited processing capacity

Although the chemical oxidation technology has a good removal effect, it often requires huge auxiliary treatment equipment, dosing catalysts, etc., which has problems such as high operating costs, cumbersome procedures, and easy to cause secondary pollution.
