Emergency treatment method and device of sudden environmental pollutants of drinking water in water source area

Abstract

The invention relates to emergency treatment method and device of sudden environmental pollutants of drinking water in a water source area. In the method, a strong electric field ionic discharge method is adopted, ionized H2O and ionized O2 are directly processed into a hydroxyl radical OH<.> according to a hydroxyl molecule structure, and the OH<.> and a part of water to be treated are respectively input into a high-efficiency gas-liquid jet dissolver to fully mix and generate a 20-30mg / L hydroxyl solution; and the generated hydroxyl solution and the water to be treated are respectively input into a high-efficiency liquid-liquid jet dissolver through a transport pipeline and are output after fully mixing in the high-efficiency liquid-liquid jet dissolver. The device comprises a gas preprocessor, a plasma source, the gas-liquid efflux jet dissolver, the liquid-liquid jet dissolver and the like. The invention can efficiently kill microorganisms such as cyanobacteria and the like, degrade organic pollutants such as microcystic toxins, phenol and the like, realize that polluted drinking water is continuously and rapidly treated on line and has the advantages of high oxidation rate, low energy consumption, short treatment time, little occupied land and the like.

Description

technical field [0001] A method and device for emergency treatment of sudden environmental pollutants in drinking water in water sources, belonging to the technical fields of gas discharge physics and environmental engineering. Background technique [0002] In recent years, with the rapid development of industrial and agricultural production, the development of tourism, leisure and holiday industries, sewage containing a large amount of nitrogen and phosphorus nutrients has entered lakes and reservoirs, resulting in a significant increase in the nutrient content of the water body and a substantial increase in the amount of phytoplankton. As a result, the trophicization of the water body is intensified, and the organic pollution increases, which leads to the outbreak of cyanobacteria blooms. After the cyanobacteria cells die and rupture, a large amount of cyanotoxin MC is produced in the water. Cyanotoxins can cause chromosome breakage, gene mutagenesis and high acute toxici...

Problems solved by technology

However, these technologies have different defects in the actual application process, such as incomplete killing, especially the control of some spore-producing strong pathogenic bacteria is very difficult; chemical methods are difficult to avoid environmental pollution problems, so the development of new killing It is imminent to study the technology of killing or inhibiting pathogenic microorganisms
