Abstract
The invention discloses an efficient urea degrading agent for swimming pools and a preparation method thereof. The degrading agent comprises the following raw materials in percentage by weight: 3-10% of urease, 20-35% of a water-soluble carrier, 0.2-1% of a surfactant, 0.1-2% of inorganic alkali, and 65-80% of water. The preparation method disclosed by the invention is implemented through adding water, a carrier and a surfactant in formula ratio in a reactor; heating the obtained mixture to 30-40 DEG C; adjusting the pH value of the mixture to 9-10.5; and finally, adding urease in formula ratio, stirring until the urease is dissolved, drying the obtained product, so that urea degrading agent powder particles are obtained. The urea degrading agent prepared according to the invention is low in cost, good in degradation effect and long in acting time, and can quickly and efficiently degrade urea in pool water into ammonia and carbon dioxide which are harmless to human bodies, so that the replacement of pool water can be reduced, thereby lowering the operation cost.
Description
Technical field
The present invention relates to degradation of urea agent field, particularly relate to a kind of swimming pool highly effective carbamide degradation agents and preparation method thereof.
Background technology
In the summer of sweltering heat, swimming is the first-selection of people's outdoor activity.But because swimming process middle reaches swimmer's health directly contacts with Chi Shui, the health of water quality on swimming colony of Chi Shui has direct impact.Simultaneously in the immersion process of human body when swimming pool, body surface has a large amount of foul and secretory product and comes off and be dissolved in the water, and makes Chi Shui contaminated, contains a large amount of bacteriums and various pathogenic bacterium in these organic pollutants.Good water quality not only plays an important role to numerous swimmers are healthy, and on preventing the propagation of transmissible disease and popularly having direct impact.The selection of effective sterilizing and purifying technology, seems most important to guarantee swimming pool water quality secure context.
In swimming pool, organic pollutant mainly comprises bacterium, microorganism and urea etc.At present, the process for organic pollutant mainly contains three kinds of modes: filter, oxidation sterilizing and refreshing the water periodically.Wherein filter general employing quartz sand or diatomite, also have and use more medium filter or charcoal absorption to filter.Oxidation sterilizing mainly adopts various a oxidizing disinfect, as clorox and ozone.Refreshing the water periodically, is regularly change Chi Shui.
But all there is respective deficiency for urea in the water of removal pond in above three kinds of modes.Use the mode of filtering, only can remove bacterium and microorganism, and for water miscible urea, substantially inoperative.Adopt the mode of oxidation sterilizing, although the organic pollutant in swimming pool effectively can be removed, but urea and chlorine-containing disinfectant react, the carcinogens halogen acetic acid to human health, haloform and chlorine ammonia can be produced, because chlorine ammonia can stimulate respiratory tract and the skin of people, meeting grievous injury swimmer's is healthy.And not only running cost of refreshing the water periodically is high, and be restricted because of quantity of exchanged water, in the water of pond, the concentration of urea increases along with the prolongation of time, so that severe overweight.
Summary of the invention
The object of the invention is to the deficiency overcoming the existence of above-mentioned prior art, provide a kind of swimming pool highly effective carbamide degradation agents, its price is low, and fast to the degradation speed of urea, effective, long action time, can not produce harmful by product.
Meanwhile, present invention also offers a kind of preparation method of swimming pool highly effective carbamide degradation agents.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of swimming pool highly effective carbamide degradation agents, is characterized in that basic recipe and weight percent consist of:
Preferably, described urase be urase solution and containing urase culture in one.
Preferably, water-soluble carrier is one or several the mixture in Sodium sulfate anhydrous.min(99), chitosan, glucose, semi-lactosi and sucrose.
Preferably, described tensio-active agent is one or several mixture of Sodium dodecylbenzene sulfonate, cetyl trimethylammonium bromide, stearic acid and glycerin fatty acid ester.
Preferably, described mineral alkali is any one in SPC-D, NaOH, KOH and ammoniacal liquor.
Above-mentioned swimming pool highly effective carbamide degradation agents, its technique prepared is as follows:
Add the water of formula ratio in the reactor, be heated to 30 ~ 40 DEG C, add water-soluble carrier and the tensio-active agent of formula ratio, mixing.Add the mineral alkali of formula ratio again, mixing, regulate pH 9 ~ 10.5, the urase finally adding formula ratio is stirred to dissolving, dry, obtains degradation of urea agent powdered granule.
The present invention, by urase is loaded on water-soluble carrier, prepares degradation of urea agent.Its price is low, good degrading effect, can be harmless ammonia and carbonic acid gas by the degradation of urea of Chi Shuizhong fast and efficiently, throws to spread decomposable asymmetric choice net in latter 2 days and purified the urea in the water of pond, and has long-lasting to the degraded of urea.Meanwhile, add tensio-active agent, improve the activity of urase in water.The present invention does not react with sterilizing agent, can not reduce the sterilisation effect of sterilizing agent, also can not produce harmful by product.In addition, the present invention can reduce the replacing of Chi Shui, reduces running cost, for improvement, the healthy important in inhibiting of guarantee swimmer of swimming pool water.
