Abstract
The invention relates to the field of application of advanced oxidation technology and biology technology, in particular to a method for disinfecting water of a swimming pool through the advanced oxidation technology using free radicals of sulphuric acid. The method comprises that: after a flocculant is thrown into the water of the swimming pool for depositing impurities with large particles, persulfate or single peroxy-hydrosulfate is thrown into the water of the swimming pool; simultaneously, cobalt salt is thrown into the water in the molar ratio of the persulfate or the single peroxy-hydrosulfate to the cobalt salt of between 50 to 1 and 100 to 1; and the throwing amount of the cobalt salt is within the range of between 0.1 and 1g/cubic meter of the water of the swimming pool. The persulfate or the single peroxy-hydrosulfate generates the free radicals of the sulphuric acid in a cobalt ion catalysis mode; the free radicals of the sulphuric acid with high oxidation activity can kill bacteria and algal organisms in the water of the swimming pool and degrade urea and ammonia waste excreted by human body. The method has good sterilization effect, is safe and friendly to human body and environment, and has safe disinfection, cheap price of medicine, and low operating expense and cost.
Description
Technical field
The present invention relates to high-level oxidation technology and biology techniques Application Areas, the high-level oxidation technology that is specifically related to produce sulphuric acid free radical is applied to kill the method for refuses such as bacterium living beings in the swimming pool, human body excretory urea, Ammonia, Creatinine, arginine.
Background technology
Swimming sterilizing medicament commonly used at present comprises that chlorine system and oxygen are disinfectant two big classes.Chlorine is that disinfectant mainly is meant chlorine-containing disinfecting medicaments such as chlorinated lime, clorox.Chlorinated lime color white powder shape, main component is compound calcium salt, its effective constituent is exactly Losantin (Ca (ClO) wherein
2), Losantin (Ca (ClO)
2) water-soluble generation calcium oxide precipitation and hydrochloric acid, and producing the nascent oxygen sterilization, sterilizing power is stronger.Shortcoming is that storage, transportation are inconvenient, and Chi Shui has residue.Clorox is that liquid is yellow, water-soluble generation hypochlorous acid (HClO), and sterilizing ability is stronger.Advantage is to use conveniently, and Chi Shui does not have residue, and lasting effect is good; Shortcoming is that storage, transportation are inconvenient, cost is high.Chlorine is that the main drawback of disinfectant mainly is to produce chloride relevant disinfection byproduct (DBP) such as trieline, and these by products can produce harm to skin, eyes and respiratory system, " three cause " effects such as carcinogenic in addition, teratogenesis, mutagenesis.Oxygen is that disinfectant mainly is meant products such as ozone, produce ozone by ozonizer, ozone is fast to microorganism killing rate height such as bacterium, virus, speed in water, removal thoroughly and not produces secondary pollution to pollution substances such as organic compound, and can reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD), remove nitrite, suspended solids and decolouring.Its shortcoming is that ozonization is high to the pH value requirement of water, and period of decay is short, so be suitable for small-sized swimming pool.In addition, the ozonizer equipment price is also relatively more expensive, and routine maintenance expense and running cost are higher.
Summary of the invention
The high-level oxidation technology that the purpose of this invention is to provide a kind of application generation sulphuric acid free radical kills the method for the bacterium living beings in the swimming pool, utilize this method not only to kill microorganisms such as intestinal bacteria unwanted bacteria in the water, algae, can also the degrade refuses such as urea, Ammonia, Creatinine, arginine of human body discharging in the swimming pool, simultaneously do not produce deleterious disinfection byproduct (DBP), to human body and environmental friendliness.
Know-why of the present invention: the cobalt salt and the persulphate (S that add some amount in the water
2O
8 2-) or single peroxosulphuric hydrogen salt (HSO
5 -), persulphate (S
2O
8 2-) or single peroxosulphuric hydrogen salt (HSO

The sulphuric acid free radical that is produced by above-mentioned reaction has very high oxidation activity, can with the biological respinse in the swimming-pool water, materials such as biolytic cell membrane lipid layer, protein, carbohydrate and DNA, thereby killing bacteria and algae bio, the urea and the Ammonia refuse of human body discharging in the swimming pool of can also degrading.
Technical scheme of the present invention is: swimming-pool water is through adding flocculation agent precipitation macrobead foreign material, persulphate (S
2O
8 2-) or single peroxosulphuric hydrogen salt (HSO
5 -) put in the swimming-pool water, the while is S in molar ratio
2O
8 2-Or HSO
5 -: Co
2+=50～100:1 ratio adds cobalt salt, and the quantitative range that adds of cobalt salt is every cubic metre of swimming-pool water of 0.1～1g/.Persulphate (S
2O
8 2-) or single peroxosulphuric hydrogen salt (HSO
5 -) through cobalt ion (Co
2+) catalysis, produce sulphuric acid free radical, the sulphuric acid free radical with high oxidation activity can kill intestinal bacteria and the algae bio in the swimming-pool water, the urea and the Ammonia refuse of the human body of degrading simultaneously discharging.Implementation result can be weighed with intestinal bacteria inactivation ratio and Ammonia, Creatinine, arginine decreasing ratio.
The invention has the beneficial effects as follows:
(1) it is good to kill biological effect.Medicament is at lower concentration (KHSO
5, 12ppm; CoSO
4, 0.1ppm) under the condition, intestinal bacteria were removed near 100% after 1 hour;
(2) degraded human body effluent discharge is effective.Medicament is at lower concentration (KHSO
5, 12ppm; CoSO
4, 0.1ppm) under the condition, ammonium ion was removed near 70% after 5 hours;
(3) the present invention is not chloride, does not have the disinfectant by product, to human body and environmental safety close friend.This medicament works by catalyzed reaction simultaneously, and sulphuric acid free radical slowly discharges, so long sterilizing time, and evenly sterilization is non-stimulated to human body, safe disinfection;
(4) do not need extra special equipment, one-time investment is low, and it is little to consume energy, the medicament low price, and working cost and cost are low.
