Water treatment method for swimming pool or hydrotherapy pool

Abstract

The invention discloses a water treatment method for a swimming pool or a hydrotherapy pool. 2 percent to 10 percent of water in the swimming pool or the hydrotherapy pool is taken per hour to be sequentially treated by the following steps of: removing a disinfectant in the water, wherein the disinfectant comprises chlorine, bromine and ozone and in the process of removing the disinfectant in the water, the speed of water flow needs to be guaranteed to be below 20m / h; using activated carbon, quartz sand or ceramsite as a biological carrier for carrying out biodegradation on the water subjected to removal of the disinfectant so as to remove organisms in the water, wherein empty bed residence time of biodegradation is over 3 minutes; carrying out filtering purification and disinfection on the biodegraded water to remove suspended matter and microorganisms in the water. The method disclosed by the invention can effectively decompose urea, ammonia nitrogen and other organisms in the pool water, can greatly improve water quality and reduce the use amount of the disinfectant and the volume of changed water.

Description

technical field [0001] The invention relates to a water treatment method for a swimming pool or a hydrotherapy pool. Background technique [0002] The swimming pool of the present invention is a general term for competition swimming pools, public swimming pools, special-purpose swimming pools, private swimming pools and recreational pools. The recreational pool is built for the main purpose of playing in water, leisure and entertainment, and is equipped with various water entertainment facilities and pools of different shapes and water depths. Such as children and adult paddling pools, slides and drop pools, wave pools, circulating rivers, etc. Organic pollutants in swimming pools, spa pools and other similar water environments mainly come from skin, secretions, urine, sweat, skin care products, cosmetics, etc. brought in by the human body, most of which are dissolved organic substances such as urea. These dissolved organic substances not only increase the consumption of o...

Problems solved by technology

[0004] The above process can only intercept the suspended solids in the water and carry out oxidation and disinfection, but cannot effectively remove the dissolved urea, ammonia nitrogen and organic matter in the pool water

Even if the activated carbon adsorption process is used, it can only adsorb part of the dissolved organic matter with a molecular weight of 400-2000, but has no adsorption effect on organic matter with other molecular weights, urea, ammonia nitrogen, etc.

Moreover, due to the small area of ​​the swimming pool machine room and the small filling capacity of the activated carbon tank, the activated carbon will quickly absorb and saturate, and the activated carbon that has been used for more than half a year will not have an obvious adsorption effect on organic matter.

[0005] In the current swimming pool design regulations at home and abroad, only the physical and chemical treatment of swimming pool water is considered, and biological treatment is not considered. Under the dominance of this concept, the current swimming pool design regulations require that the adsorption tank with activated carbon must have a higher filtration rate , up to 30-35m / h, at this time, due to the high flow rate of water flowing through the activated carbon layer, the activated carbon has no time to decompose chlorine and other oxidizing disinfectants, and the residual chlorine or other disinfectants in the water will kill the microorganisms on the activated carbon, and the activated carbon will not be able to Play the role of biological carrier, can only play the role of adsorption
