Importance of strengthening water treatment of swimming pool in natatorium
With the progress of modern society, swimming has become a common sport. It integrates entertainment and fitness, so it is very popular. In addition to the improvement of people's living standards, swimming has become a mass recreational activity. However, there is a concern that the cleanliness of the swimming pool is directly related to people's health because the crowd in the pool is muddy and the disease is easy to infect. For the sake of everyone's health, it is necessary to strengthen the water treatment of the swimming pool and kill bacteria lamp.
At present, the research on swimming pool water treatment technology at home and abroad has gradually matured, and more and more water treatment plants are also developing new swimming pool water treatment equipment according to swimming pool projects.
1、 Water quality standard of swimming pool
Pool water may become the source of infection of diseases because of its direct contact with human body. As a result, countries all over the world have a clear demand for the water quality of swimming pools. In China, the initial water filling and replenishment of swimming pools should comply with the rules of the Daily Drinking Water Cleaning Standard (GB5749-85), and the water quality of swimming pools should comply with the water quality standards for swimming pools in GB9667-1966 jointly issued by the National Skills Supervision Bureau and the Ministry of Cleaning
2、 Impact of water quality of swimming pool on human health
The purpose of eliminating bacteria in swimming pool water treatment and installing swimming pool water treatment equipment is to prevent water quality from deteriorating and damaging human health.
The deterioration of swimming pool water quality is shown as follows:
1. The addition of suspended solids and dissolved solids, which can breed algae, will increase the turbidity of the pool water, making people feel disgusted.
Summer is the high incidence period of various infectious diseases, and germs can be transmitted through the swimming pool. The common health damage caused by unclean pool water is infectious epidemic bleeding (commonly known), and the second reason is that the swimmer feels that his eyes and nose are affected by the excessive dosage of chlordecone. If not handled well, it can also lead to infection; Overexpenditure of coliform bacteria will lead to diarrhea and gastrointestinal infection, swimming pool fever (also called swimming pool fever), infectious soft warts (also called water warts) and otitis media.
2. The addition of organic load and the formation of halohydrocarbon during chlorination. It was found that the COD, urea and chloroform increased significantly at the peak of the swimming season after one week of use of the fully water changing swimming pool. The urea in the detected water sample is on the high side, which means that the swimmer's skin substances fall off more and the swimmer urinates more in the swimming pool;
3. The number of microorganisms in the pool water is added, and there is the possibility of the proliferation of pathogenic microorganisms. The test results showed that except the total number of bacteria and coliform bacteria increased with the number of swimmers, the pollution of HBsAg (hepatitis B surface antigen) also increased with the number of swimmers.
3、 Measures to strengthen water treatment of swimming pool
Swimming pool water treatment is an important guarantee to ensure the water sterilization and healthy operation of swimming pool. In the operation practice, the following three key measures are summarized:
1. Strengthen security measures. The artificial swimming pool shall be equipped with forced foot dipping pool (residual chlorine ≮ 5mg/L) and shower channel.
2. Complete online control and real-time detection of the swimming pool water treatment system. Under the premise of given equipment and technology, the water treatment function of swimming pool depends largely on the control of various water quality parameters. If disinfectant sterilization and formula elimination rules are selected, pay attention to monitoring the change of residual chlorine and pH value, and make up for the disinfectant and pH regulator in time to ensure the quality of pool water.
3. Strengthen physical examination for swimming pool entry. Patients suffering from hepatitis, dermatophytosis, severe trachoma, acute, otitis media, intestinal infection and other diseases are strictly prohibited to enter, so as to avoid interspersed infection and spread of infectious diseases.
4、 Sterilization method for swimming pool water treatment
1. UV elimination
Ultraviolet sterilization refers to the function of using ultraviolet rays of appropriate wavelength to damage the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microbial organism, resulting in the death of growth cells and (or) the death of regenerative cells, so as to achieve sterilization. Based on modern epidemic prevention, medicine and photodynamics, the ultraviolet ray elimination skill uses specially planned UVC band ultraviolet light with high efficiency, high intensity and long life to shine on the flowing water, and directly kills various bacteria, diseases, parasites, algae and other pathogens in the water to achieve the purpose of elimination. Because the ultraviolet ray elimination belongs to the instant elimination, and only the ultraviolet ray water can be sterilized, the ultraviolet ray elimination also needs to be compensated by chlorine elimination.
2. Ozone sterilization
Ozone is a strong oxidant. Its redox potential in water is 2.07V, second only to fluorine (2.5V). Its oxidation ability is higher than that of chlorine (1.36V) and chlorine dioxide (1.5V). It can damage the cell wall of differentiation bacteria, quickly disperse into cells, oxidize and differentiate bacteria, oxidize all necessary glucose oxidase, etc. inside glucose, and also directly contact bacteria The disease attack can damage cells, ribonucleic acid (RNA), differentiate deoxyribonucleic acid (DNA), RNA, protein, lipids, polysaccharides and other macromolecular polymers, and damage the metabolism and reproduction process of bacteria.
Unlike hypochlorite disinfectants, the sterilization ability of ozone is not affected by pH changes and ammonia. Its sterilization ability is 600~3000 times larger than that of chlorine. Its sterilization and disinfection effects are almost instantaneous. Ozone has a high oxidation ability, which can quickly kill bacteria, fungi, Escherichia coli, diseases and other pathogenic microorganisms in water, and can completely oxidize organic matter to achieve color, taste With the function of reducing turbidity, the natatorium water treatment improves the water body goals, improves the physical, chemical and biochemical goals of the water body, and makes the water body present a pleasant blue.
3. Disinfection, sterilization and disinfection
Liquid chlorine, hypochlorite, inorganic chloramine, organic chloramine and chlorine dioxide can all be used as disinfectants. Chlorine containing disinfectant is due to the simple formation of hypochlorite in water, which has a strong oxidation effect. It can not only interact with cell wall, but also because the molecule is small, neutral and uncharged, which can be dispersed to the surface of negatively charged bacteria, simply penetrate the cell membrane into the bacteria, damage some enzyme system of bacteria, and cause the imbalance of sugar metabolism, leading to the death of bacteria.
The advantages of disinfectant killing are wide sterilization spectrum, rapid action and reliable sterilization effect; Low sex; It is easy to use and cheap. Its defect is unstable, and available chlorine is easy to lose; Bleaching effect on fabric; Corrosive; It is easily affected by organic substances, pH, etc.
A variety of mass recreational activities.
