Environment-friendly water treatment agent for swimming pool water treatment and preparation method of agent

Abstract

The invention provides an environment-friendly water treatment agent for swimming pool water treatment and a preparation method of the agent. The preparation method includes the following steps: mixing houttuynia cordata, sesame leaves and garlic, adding ethanol to grind, and filtering to obtain a first mixed solution; mixing flos caryophylli, tulips, flos lonicerae, cortex pseudolaricis, scutellariae radix, lavender, aloe, stigma croci sativi, zingiberis rhizoma, prunellae spica and folium artemisiae argyi, adding water, boiling, and filtering to obtain a second mixed solution; mixing polyhexamethylene guanidine, the first mixed solution and the second mixed solution to obtain a third mixed solution; mixing bovine serum protein, potassium gluconate, sucrose, chitosan, gelatin and acetic acid, then adding urease to mix to obtain a fourth mixed solution; immersing columnar activated carbon in the third mixed solution for 20-40 minutes and drying, then mixing the mixture with the fourthmixed solution in step 4 for 30-60 minutes, and naturally drying to obtain a target product. The water treatment agent prepared by the method can effectively decompose organic matters such as urea andthe like in pool water, is safe and environment-friendly, and has sterilization and disinfection effects at the same time.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an environment-friendly water treatment agent for swimming pool water treatment and a preparation method thereof. Background technique [0002] Swimming is a favorite sport of people. Swimming can not only enjoy the fun of being in contact with water, but also achieve the effect of strengthening the body. Especially in the hot summer, swimming in the swimming pool is indeed a very pleasant enjoyment. With the improvement of people's living standards, indoor swimming provides swimming places that are not restricted by seasons for the majority of swimming enthusiasts. 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.

AI Technical Summary

Problems solved by technology

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. It cannot be filtered out by conventional filtration processes. These dissolved organic substances not only increase the amount of oxidizing disinfectants such as ozone and chlorine, and increase the cost of chemicals, but also react with chlorine disinfectants to produce carcinogens that are harmful to human health.

[0003] Studies have shown that the average urine output per person in swimming pools is 50ml, and the urea content in urine is 1.8%. During the peak passenger flow in summer, a 2000m 3 In a standard swimming pool, the daily passenger flow is about 3,000, and it only takes 3 days for the content of urea and other organic matter to reach the upper limit of the standard. At present, the method for reducing organic matter in swimming pools at home and abroad is to change the water, which causes a lot of waste of tap water, and at the same time The newly replenished tap water also consumes a lot of energy for heating, which brings a heavy burden to the operation of the swimming pool

Therefore, at present, the domestic swimming pools cannot meet the required water exchange volume during operation. During the summer peak, more than 90% of swimming pools have excessive urea and combined residual chlorine, and many swimming pools have urea content above 10mg / L. The residual chlorine content exceeds 1.0mg / L, and the CODMn content exceeds 10mg / L, which will cause poor water and air quality and endanger human health

[0004] The existing swimming pool water treatment process mainly uses filtration to intercept and then oxidize and disinfect, but it cannot effectively remove dissolved urea, ammonia nitrogen and organic matter in the pool water

Even if the activated carbon adsorption process is used, it can only absorb some 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. At the same time, a small amount of fresh water is often added due to the water circulation process in the swimming pool. water, so microbiological problems cannot be completely ruled out
