The swimming pool disinfectant added to the human body what harm?
liquid chlorineChlorine is a dangerous poisonous gas, storage, transportation and use requires specialized equipment and personnel, the use of the drug safety accident prone, and easily spilled liquid, chlorine odor, pollution of the environment, the swimming pool has been rarely used.What is residual chlorine, why should the pool control residual chlorine?The so-called refers to the swimming pool chlorine chlorine disinfectant residual in the cast after free chlorine in water, it represents the dosage to kill bacteria and viruses and still remaining, which can guarantee the disinfection effect of water, the state pools of water to reach 0.4~0.6mg/L,Residual chlorine is required to maintain effective disinfection of water, and not to smellAdverse agents, cancer, hidden troubleAccording to the survey report of the national health supervision department: in recent decades, indoor and outdoor swimming pool water with chlorine or chlorine preparation disinfection treatment, found irritant gas in the process of chlorine disinfection pool water not only emit unpleasant, the swimmers red eyes, yellow hair, skin and crimp damage also, other organic chlorine and ammonia water, bring urine, sweat and the formation of a large number of halomethane three carcinogens and three chloramine toxic substances.
Three cyanuric acid (TCCA)Three chloro isocyanuric acid (TCCA), alias strong acid, white crystalline powder, are processed into granular, flake, is organic chlorine disinfectant, not easy to decompose, preserved for 1 years in a dry environment, the effective chlorine content decreased only 1%, three chloro isocyanuric acid (TCCA) in the hydrolysis process of several almost all forms of hypochlorite, hypochlorous acid is a strong oxidizing agent, it can make the protein oxidative denaturation of the pathogenic bacteria of death, because hypochlorous acid is small, strong penetrating ability, therefore, the sterilization effect is high, according to the determination, in the same concentration, bactericidal water 80~100 times stronger than.In addition, the TCCA has a long duration of efficacy and has the disinfection function of oxygen, which can increase the oxygen content in the water, precipitate after the water and instant, etc..Dosing rate is m32~3 grams per gram.
2) bleaching water (sodium hypochlorite): the solution of caustic soda through chlorine. Its effective chlorine content is greater than (equal) 10% (national standard), and the remaining 90% is salt water.In alkaline environment, the killing effect of hypochlorite is very poor, only 1% of hypochlorite. Obviously, if the hypochlorite can be stabilized so that it can not be dissociated into hypochlorite, the bactericidal effect can be increased by 99 times.Therefore, in recent years, the development of three uric acid (TCCA) gradually replaced the bleaching water.
Bleaching powder: it is a mixture of sodium chlorite, calcium chloride and calcium hydroxide. It is a white to grayish powder or particle. There are significant chlorine odor, the nature is very unstable, moisture absorption is strong, easy to be affected by moisture, light and heat decomposition, and also can react with CO2 in the air. The water solution is alkaline, aqueous solution of effective chlorine release composition, oxidation, sterilization, bleaching effect, but the sediment, the water surface has a layer of white floats, stimulate the gastrointestinal mucosa, respiratory tract, skin, and can cause cough and affect vision.Dosage: about 20~30Kg per 1000m3.
