Description
Technical field
The utility model relates to Drinking Water Sanitization Technology field, is specifically related to a kind of based on light-catalysed drinking water sterilization device.
Background technology
At present, the aggravation of water pollutions causes drinking water source water to be micro-pollutional condition, and waterworks safety water supply is on the hazard day by day.According to China's environment publication in 2011,2011, national surface water was totally slight pollution.Lake (reservoir) eutrophication problem is still given prominence to.In 469 state's control sections of the Changjiang river, the Yellow River, the Zhujiang River, Song Hua River, Huaihe River, Haihe River, the Liaohe River, Min Pian river, Zhejiang, the large water system monitoring in all rivers ten of south-west rivers and inland, I ~ III class, IV ~ V class and bad V class water quality section ratio are respectively 61.0%, 25.3% and 13.7%.Main contamination index is chemical oxygen demand (COD), five-day BOD and total phosphorus.2011, national environmental protection key cities year water intaking total amount was 227.3 hundred million tons, and service population 1.63 hundred million people, wherein the water yield not up to standard is 21.3 hundred million tons, accounts for 9.4%.
In mass-producing waterworks, sterilization is the most basic treatment process, and its object ensures user security water exactly.Cholorination is sterilization process extensive, most economical, also the most ripe at present.But Natural Organic Matter in Raw (NOM), organism, bromide and iodide etc. can occur to replace or addition reaction with chlorine, generate various halides, are also disinfection byproduct (DBP) (DBPs).These disinfection byproduct (DBP) comprise haloform (THMs), chlorophenol, halogen acetic acid (HAAs), dichloro acetic acid (DCA), trichoroacetic acid(TCA) (TCA) etc., there is very strong carcinogenic risk, liver poisoning, the harm such as neurotoxic and metabolism disorder that also can cause people that have.And emerging disinfection byproduct (DBP), comprise halogenated amine, halogenated acid, aldehydes, halogen acid amide, tribromo pyrroles, iodo-acid, alkane iodide and iodofuran ketone etc., day by day receive publicity in drinking water treatment.Along with being used alone or in combination of multiple sterilizing agent, increasing DBPs is detected in tap water, and more than the 600 kind of DBP defined in tap water has been recognized in the research of Past 30 Years.
The approach reducing disinfection by-product of drinking water mainly contains 2 points, is first to reduce Natural Organic Matter in Raw content, namely to the control of DBPs precursor; Next is the improvement of chlorine disinfectant technique under the prerequisite ensureing drinking water safety.Due to natural organic matter composition complicacy, coagulation, the filtration of traditional waterworks add Chlorination Process, are difficult to remove in water remain NOM, and in its water outlet, DOM concentration often reaches 5mg/L.For reducing organic content, take the aggregate measures such as the absorption of front end ozone pre-oxidation, end Powdered Activated Carbon, biological activated carbon and membrane filtration technique.The removal of Active Carbon in Organic is mainly by its huge specific surface area and the absorption of flourishing space, improve conventional water treatment process, remove one of the most ripe effective means of organic pollutants, but it is high to there is back flushing power consumption, the shortcomings such as regeneration expense is high, and being subject to the impact of NOM molecular weight, the adsorption efficiency of gac is on the low side.Ozone utilizes its strong oxidizing property, larger molecular organics in water can be made to be converted into small organic molecule, change its molecular morphosis, but due to the existence of natural organic matter (NOM), a large amount of ozone can be consumed, and the limit of ozone Oxidation Treatment dissolved organic matter (DOC) is 1mg/L, then increases ozone dosage processing costs can be made greatly to increase, very uneconomical.And larger molecular organics is just oxidized to intermediate product by ozone, intermediate product decrease in molecular weight, but value volume and range of product both increases, especially the intermediate product generated is as aldehyde, ketone and acid compounds, comprising that formaldehyde and bromate be possible carcinogens, and its hazardness is in conceptual phase.For this reason, exploitation has wide spectrum, efficient, continuous disinfection function, and can reduce life disinfection byproduct (DBP) brings health risk sterilizing unit to user, protects urbanite water consumption healthy, is significant.
