Description
Technical field
The utility model relates to organic device in a kind of ultraviolet lighting and the collaborative elimination of clorox water, belongs to water-treatment technology field, is mainly used in the processing of town domestic sewage and industrial sewage.
Background technology
Along with the growth of population and the fast development of economic society, water resources in china is in short supply will be on the rise.Corresponding with shortage of water resources, another water problems of China is water environment pollution.China's water pollution is mainly from two aspects, and the one, industrial development discharge beyond standards trade effluent, the 2nd, in urbanization, due to town sewage discharging and facility for the central disposal famine, the unprocessed water bodys that directly enter of sanitary sewage cause environmental pollution in a large number.In recent years, the town domestic sewage quantity discharged was with average annual 5% speed increase, and surpassed first the industrial sewage quantity discharged in 1999, accounted for 52.9% of national total amount of sewage discharge.China Environmental State Bulletin statistics in 2003, whole nation industry and urban life wastewater emission amount are 46,000,000,000 tons, wherein discharged volume of industrial waste water is 212.4 hundred million tons, 247.6 hundred million tons of town domestic sewage quantity dischargeds, 1333.6 ten thousand tons of chemical oxygen demand (COD) in waste water (COD) total emission volumns, in town domestic sewage, the COD quantity discharged is 821.7 ten thousand tons.As can be seen from the above data; town domestic sewage has become the first source that water pollutes; its control is directly connected to the protection of water body, water quality and the sustainable use of water resources; it is one of emphasis of China's water prevention and cure of pollution and environment protection; for improving city environmental quality and resident's living environment, promote the Sustainable development tool of society to be of great significance.
Town domestic sewage refers to that mainly the facilities such as city resident family, hotel, institutional settings, school, market due to the sewage that life utilization produces, mainly comprise: flushing supply, life bath water, kitchen waste water etc.These domestic water consumptions are large, often contain the inorganicss such as higher organism (as protein, grease, starch etc.) and nitrogen, phosphorus, in addition, also contain pathogenic micro-organism and more suspended substance.
Pollutent in town domestic sewage generally includes three major types: organism, suspended solids (SS), nutrition (phosphorus and nitrogen), these pollutents are all the removal objects of conventional processing (take qualified discharge as main purpose) and advanced treatment (take regeneration as main purpose).It is main coagulation and take biological treatment as main two stages of second-stage treatment that conventional sewage disposal is divided into again physical removal usually.Wherein, represent organic pollution level in water body with chemical oxygen demand (COD) (COD) and biochemical oxygen demand (BOD) (BOD) numerical value, numerical value is larger, and water body is more serious by the degree of Organic pollutants.COD and BOD value have become the important parameter of many water quality detection standards at present, are one of most important water quality parameters of present sewage treatment area.
Domestic sewage processing method is divided into Physical, physical chemistry and chemical method, biochemical process and electrochemical method.Generally each treatment process is used seldom separately, mostly adopts the form of two kinds or two or more method combinations to carry out sewage disposal.Wherein reduce COD and the BOD value has following several method:
Physical: adopt mechanical means to remove suspended solid magazine in sewage, generally comprise: screen out, the technology such as precipitation, air supporting, filtration and membrane sepn.Its principle is namely to make the organism that is attached to solid particles surface along with solid is separated from water together, thereby reduces COD and BOD value.
Physical chemistry and chemical method: add some chemical substance in sewage, the pollutent by in effect separation, conversion, destruction or the recovery sewage of chemical reaction and medicament mainly comprises coagulating sedimentation, neutralization, redox, absorption electrodialysis etc.Chemical method mainly utilizes the effect of chemical reaction to process pollutent.
Biochemical process: utilize microbiological deterioration, make the organic pollutant in sewage transform, decompose.Biochemical process can be divided into aerobe to be processed and anaerobic biological treatment.Method commonly used has activated sludge process and biomembrance process.
Electrochemical process: utilize after the energising of special battery lead plate by the contacting of pole plate and sewage, the organism in direct oxidation water is decomposed into carbonic acid gas and water with it; Or utilize electrochemical reaction, and produce electric flocculation process, produce colloid in water, suspended substance in absorption sewage, there is or is attached to solid particles surface in partial organic substances with suspended state, can be removed from water body with colloid, thereby reach the effect that reduces COD and BOD.
Make in all sorts of ways reduce water in when COD and BOD value, all have certain limitation: utilize Physical or electro-flucculation process to separate by the organism that insoluble solid in water is entrained from water, for the organism that is dissolved in water, these methods can not play the effect that reduces COD and BOD value; For biochemical process, after organism, reduction COD and BOD value in bacterial degradation water, according to the relevant criterion requirement, also need to throw in addition sterilant (clorox) and kill intestinal bacteria in water, in addition, many standards also have mandatory requirement to the residual concentration of processing clorox in rear water, therefore need to carry out necessary neutralization; Adopt the electrolytic process energy consumption higher than other several methods, in addition, as electrolysis under the fresh water condition, still need add sterilant to process after processing.
