Description
Technical Field
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
Swimming is a favorite sport for people, and the swimming can not only enjoy the pleasure of contacting with water, but also achieve the effect of building up the body. Particularly in the summer with inflammation, the swimming pool can swim smoothly, which is really very agreeable enjoyment. With the improvement of living standard of people, indoor swimming provides a swimming place which is not restricted by seasons for the majority of swimming enthusiasts. The organic pollutants in swimming pools, hydrotherapeutics and other similar water environments mainly come from skin drops, secretions, urine, sweat, skin care products, cosmetics and the like brought by human bodies, wherein most of the organic pollutants are soluble organic matters such as urea which cannot be filtered out by a conventional filtering process, and the soluble organic matters not only increase the using amount of oxidation type disinfectants such as ozone and chlorine and increase the medicament cost, but also react with the chlorine disinfectants to generate carcinogens harmful to the health of the human bodies.
Research shows that the average urine output of each person in the swimming pool is 50ml, the urea content in the urine is 1.8 percent, and 2000m is at the peak of passenger flow in summer3The standard swimming pool has the passenger flow of about 3000 people per day, only 3 days are needed, the content of urea and other organic matters can reach the standard upper limit, the existing method for reducing the organic matters in the pool water of the domestic and foreign swimming pools is to change water, so that a large amount of tap water is wasted, and meanwhile, the newly supplemented tap water is high in heating energy consumption, and heavy burden is brought to the operation of a swimming pool. Therefore, at present, the domestic natatorium can not meet the water change amount required by the standard during operation, more than 90 percent of natatorium urea and chemical residual chlorine exceed the standard during the peak of summer, the urea content of many natatoriums reaches more than 10mg/L, and the chemical residual chlorine content exceeds 1.0mg/L, CODMn and exceeds 10mg/L, so that the quality of pool water and air is deteriorated, and the human health is harmed.
The existing swimming pool water treatment process mainly utilizes filtration interception and then oxidation disinfection, but can not effectively remove urea, ammonia nitrogen and organic matters dissolved in pool water. Even if the activated carbon adsorption process is used, only part of dissolved organic matters with the molecular weight of 400-2000 can be adsorbed, and no adsorption effect is generated on organic matters with other molecular weights, urea, ammonia nitrogen and the like, and meanwhile, the problem of microorganisms cannot be completely eliminated because a small amount of fresh water is frequently added in the water circulation process in the swimming pool.

Specifically, the working principle of the invention is as follows: because the existing swimming pool water treatment is usually carried out by using activated carbon for filtration, the activated carbon is used as a carrier for compounding the traditional Chinese medicine herb sterilization disinfectant and a urease carrier, on one hand, the original adsorption effect of the activated carbon is kept (removing suspended matters and dissolved organic matters with the molecular weight of 400-2000 in the swimming pool), on the other hand, the sterilization disinfectant on the activated carbon can be released or not released to kill microorganisms in water, and the urease on the activated carbon is used for decomposing organic matters such as urea and the like in the swimming pool water to ensure that the urea and the chemical residual chlorine in the swimming pool meet the national standard. The clove bud contains volatile eugenol oil, has strong antibacterial effect, can denature bacterial cell structure, eliminate organelles, obviously shrink cell membrane, denature mitochondrial structure and even disappear, and can kill 100 percent of bacteria when the bacteria are fully exposed; the tulip bud contains volatile myrcene oil and has strong antibacterial effect on dermatophytes causing tinea capitis; the honeysuckle contains volatile luteolin oil, and has strong bactericidal effect on candida albicans with strong antibacterial ability; the loosestrife has strong antifungal effect, can cause the cell structure of the fungus to denature, cell organelles to disappear, cell membranes to shrink obviously, the mitochondrial structure to denature or even disappear, and can kill 100 percent under the condition of fungus exposure; polyhexamethylene guanidine has high activity and strong affinity to microorganisms, is easily attracted by various bacteria, fungi, viruses and other microorganisms which are usually electronegative, quickly and comprehensively permeates into microbial cells, and coagulates and denatures proteins in the cells so as to inhibit the division and reproduction functions of the bacteria, the fungi and the viruses. The main components of bacterial, fungal and viral cell walls, namely peptidoglycan and lipoprotein, can be quickly broken through the synergistic effect of the components (houttuynia cordata, sesame leaf, garlic, clove, tulip, honeysuckle, loosestrife, scutellaria baicalensis, lavender, aloe, saffron, dried ginger, selfheal, folium artemisiae argyi and polyhexamethylene guanidine), and the activities of oxidase and epoxidase of bacteria can be inhibited, so that the required energy obtained by the growth, reproduction and metabolism of the bacteria through biological oxidation is destroyed, the basic life activity of the bacteria is stopped, the sterilization effect is achieved, meanwhile, the components have a good skin-care effect and are safer to use. The urease is easy to be interfered by external environment to cause instability and inactivation, and the urease is mixed with bovine serum albumin, potassium gluconate, sucrose, chitosan, gelatin and a proper amount of acetic acid, so that the activity and stability of the urease can be improved, and the removal rate of urea is ensured.

Further, the columnar activated carbon is prepared by the following method:
step a: mixing the fly ash and the shell carbonized powder, adding water, stirring, kneading for 10-20 min, adding an adhesive, and continuously kneading for 10-15 min to obtain a kneaded material;
step b: extruding the kneaded material in the step a into a columnar strip material with the diameter of 3.0-6.0 mm by using a press machine, and then baking the columnar strip material in the environment of 200-250 ℃ for 30-60 min;

The activated carbon prepared by the method has good strength, extremely small floating dust and good adsorption capacity, is directly activated in the drying process, does not pass through the carbonization process, and simplifies the working procedures; the coal ash and the shell carbonized powder are used as the raw materials of the active carbon, so that the waste can be recycled, the environment is protected, and the cost is reduced.
Further, the adhesive is starch adhesive or carboxymethyl cellulose prepared by corn starch, sweet potato starch and other starch.
