Apparatus and method for inhibiting air-conditioning cooling water legionella

Abstract

The invention discloses an apparatus and a method for inhibiting air-conditioning cooling water legionella. The apparatus employs a special material-filling technology, which is characterized in that the apparatus can control the dark light condition, constructs the growth environment for aerobic beneficial microorganism such as nitrobacteria, employs a method of on-line screening, on-line culture for beneficial microorganism and on-line treatment for water body, constructs a minisize ecology system, digests an pollutant in water body, basically eliminates the nutrition base for growth of Chlorella, inhibits the algae growth, and destroys the survival environment of host amebic protozoa of legionella, so that the purposes of inhibition of the growth of air-conditioning cooling water legionella, improvement of water quality and harmlessness treatment can be reached. According to the invention, the air-conditioning cooling water is purified, simultaneously, no sludge and no algae is generated, no chemicals is added, and no secondary pollution is generated. The apparatus for inhibiting air-conditioning cooling water legionella has the advantages of small land occupation, simple management and energy consumption saving, and realizes the purposes of local purifying and processing of the water body and high efficiency processing.

Description

technical field [0001] The invention relates to a device and a method for inhibiting legionella in air-conditioning cooling water. Background technique [0002] "Legionella" was first discovered from the veterans of the United States. In July 1976, nearly 200 participants contracted an unprecedented pneumonia and respiratory infection during a meeting of veterans held in a hotel in Philadelphia, USA, resulting in 29 deaths. Symptoms are general malaise, headache, nausea and vomiting, diarrhea, muscle pain, fever, cough, dry cough at first, followed by gray or blood-colored thick phlegm, rapid and violent illness, if not treated in time, will die of pneumonia and other complications disease. After several months of investigation and at a cost of 2 million US dollars, it was finally found that the pathogen was a bacillus that was not yet known at the time, later called "Legionella pneumophila". It was called "Legionaire's disease" because it was first identified in veterans...

AI Technical Summary

Problems solved by technology

[0005] 1. Although the use of chlorine disinfectant to kill Legionella has a certain effect, but the long-term use of chlorine-containing disinfectant for disinfection treatment will shorten the drug effect cycle, the drug resistance of microalgae and microorganisms will continue to increase, and the dosage will continue to increase , and the disinfection effect is getting worse;

[0006] 2. Chlorine-containing disinfectants are extremely volatile under the strong heat dissipation of the open-air cooling tower, and it is difficult to maintain a stable content, and at the same time pollute the surrounding environment of the cooling tower;

[0007] 3. Long-term use of disinfectant will cause serious damage to the pipeline and corrosion of pipe fittings;

[0008] 4. The amount of sludge produced by chemical dosing treatment is large, and there is a lot of dirt, and the biofilm and scale formed in the pipeline will significantly reduce the disinfection effect;

[0009] 5. The traditional chemical dosing method relies on manpower to add medicine, which is harmful to the human body and has a large workload. It is difficult to achieve a reasonable dosage of medicine, and there is a lag;

[0010] 6. Chemical dosing treatment In order to control calcium and magnesium ions in water and prevent scaling, cooling water needs to be replaced frequently, resulting in waste of water resources, and the discharge of cooling water with chemical substances will cause water environment pollution
