Description
Technical field
The utility model relates to a kind of Hospital Sewage Treatment field, is specifically a kind of hospital sewage disposal system.
Background technology
Traditional disinfection of hospital sewage agent generator mainly contains: chemical process CO 2 generator, hypochlorite generator, electrolysis chlorine dioxide generator, ozonizer etc.Sterilization, be one of important step in medical institutions' sewage disposal, the sterilization equipment that medical institutions' sewage is conventional mainly contains: ozonizer, hypochlorite generator, two siphon, electrolysis chlorine dioxide generator, chemical process CO 2 generator, intelligent Siphone chlorine dioxide sterilizer etc.Many see domestic various disinfection generator, their Common advantages has: be designed beautifully, shape differs, electrification degree is more and more higher, the tap water consumption of output specifiedization (namely hour chlorine dioxide yield is with a gram calculating) of sterilizing agent, chemical process CO 2 generator is large.The maximum of sterilizing agent output specifiedization of disinfectant generator is regretted, and be difficult to exactly meet hospital sewage mass flow discrepancy, the difficult problems such as dispensing concentration is wayward, are mainly manifested in three aspects:
1), disinfectant generator is selected according to peak period sewage quantity, titanium dioxide chlorine dose as product per hour how many grams is put in sewage, when so arriving sewage low peak period, because sewage quantity reduces, and the output of dioxide peroxide does not become, so in sewage, chlorine dioxide content must exceed standard, and not only forms secondary pollution, the another one problem brought immediately is: waste medicament, increase working cost.
2) if select disinfectant generator by low peak period sewage quantity, as product per hour how many grams of dioxide peroxide are put in sewage, when so arriving sewage peak period, because sewage quantity increases, and add Chlorine Dioxide In Disinfectant amount and do not become, sterilization dose in sewage is not inevitable, can not kill the germ in sewage and virus, causes sterilization result not reach requirement.Therefore adopt disinfectant generator sterilization hospital sewage, be difficult to solve hospital sewage mass flow discrepancy, the uppity difficult problem of dispensing concentration.
3) chemical process CO 2 generator also needs to consume a large amount of tap water, and waste resource, strengthens running cost, do not meet China's energy-saving and emission-reduction policy, tool is investigated, and small medical mechanism adopts chemical process CO 2 generator, and the water of certainly coming of consumption may be also more than sewage quantity.
1) the self-produced sterilizing agent of energy is, and can automatically regulate water seal, the water yield and water quality simultaneously, and according to the sewage water yield surely than quantitative, direct ratio dosing sterilizing agent, and satisfactorily resolve hospital sewage mass flow discrepancy, the uppity difficult problem of dispensing concentration, accomplish that sewage quantity is larger, add quickening; Sewage quantity is little, and dispensing is slowed down automatically, does not have sewage auto stop, once harmonizes, remain unchanged for a long period of time.Change the phenomenon of chlorine dioxide generator serious waste tap water, be typical safety, environmental protection, energy-conservation, reduce discharging disinfection of hospital sewage device.This kind of device mainly contains chemical method Siphone chlorine dioxide sterilizer; Electrolysis sodium-hypochlorite process hydrocone type formula sterilizing unit; Electrolysis Chlorine Dioxide Method hydrocone type sterilizing unit and the two siphon hospital sewage of automatic synchronization are surely than quantitative sterilizing unit etc.2) sewage after available processes makes the absorption liquid of disinfection agent of chlorine dioxide, does not consume tap water.Even if make absorption liquid at some places tap water, also only have 1/10th of chemical process CO 2 generator.
Disinfection of hospital sewage process (comprising the sludge disinfection of generation) be exactly by sterilizing agent by some way together with hospital sewage Homogeneous phase mixing, and keep one section of specified time, make its abundant contact sterilizing, treat that the various germs in sewage reach the Inactivation exponent of regulation, then discharge.Disinfection of hospital sewage as can be seen here, relates to sterilizing agent and sterilization equipment.Sterilizing agent produced by chemical plant or by sterilizing agent production unit formed in-situ (as chlorine dioxide generator, hypochlorite generator, ozonizer etc.), and sterilization equipment is exactly the hybrid mode or the means that solve sterilizing agent and sewage, this process means not outer two kinds so far, one mixes not electricity consumption by the method for " siphon "; Another kind is electricity consumption, namely mixes by the method for machinery.Known this point, then the clause different according to two classes selects sterilization equipment and sterilizing agent just than being easier to.The first kind: if your hospital is just in newly-built, or just preparing to transform original sewage works, as long as the height of water of 30 centimeters can be had between the import and export of newly-built sewage plant, first you just should select " the two quantitative sterilizing unit of siphon hospital sewage of automatic synchronization ", because its not electricity consumption, and other any one treatment facilities all want electricity consumption to run.After equipment choice is good, just select sterilizing agent according to the particular case of hospital.If the big city that hospital absent populations are dense, if you reduce disinfection cost, reduce expenses as the first consideration as far as possible, if you can buy liquid chlorine nearby, you might as well select liquid chlorine to make sterilizing agent, because it is minimum up to now, to add that price-rise factor liquid chlorine is still processing cost in all sterilizing agents.Certainly, if you feel that use liquid chlorine is dangerous do not mind again some processing costs of increase, can buy clorox, Losantin nearby again, you also can make sterilizing agent with these two kinds simultaneously.If what can't resolve sterilizing agent in locality carrys out source problem, then can first-selected Siphone chlorine dioxide sterilizer disinfecting sewage water.Siphone chlorine dioxide sterilizer, has the two-fold advantage of chlorine dioxide generator and two siphon, can solve sterilization source, also hospital sewage mass flow discrepancy can be solved, the difficult problems such as dispensing concentration is unmanageable, can ensure disinfection of hospital sewage steady running, be the specific equipment of wastewater disinfection.If you have disinfectant generator in the past, only need keep in repair engineering and transform, then can select the two siphon of automatic synchronization, chlorine dioxide generator or hypochlorite generator can investment reduction.Equations of The Second Kind situation: because many reasons disinfection of hospital sewage station does not possess operation 30 centimeters of heights of water.This situation is before two siphon technology occurs, engineers standing meter sewage works is the Disinfection Methods hospital sewage continuing to use " water pump lifting adds water sprayer dispensing " substantially, 60, the seventies its sewage works of hospital of setting up substantially belong to this situation.Running through four more than ten years uses, a lot of sewage treatment facility can not continue to use, with the application of stylish sewage disposal device and new disinfectant, also making a lot of hospital make a decision will in wastewater land treatment " Conditions are becoming better ", " must take out with pump in the face of this, all the time want electricity consumption " objective reality, certainly should adopt current state-of-the-art technology as far as possible, as used intelligent chlorine dioxide disinfecting device, this device is joined and is had chlorine dioxide generator system, dioxide peroxide stocking system, sensing promotes jet dosing system and automated management system four part composition, advanced technology, sterilization is reliable, stable.Certain peculiar smell to being produced in sewage treatment process, if do not processed, atmospheric pollution being caused to surrounding enviroment.Therefore, when sewage disposal, focusing on and discharging in a organized way of waste gas to also be considered.In medical institutions' sewage treatment process, the waste gas of generation has and mainly contains two kinds of way process at present: high and medium discharges: if treatment zone is away from high level, can adopt high-altitude emission by exhaust pipe on the spot.Namely airway is set on the cover plate of each structures, be interconnected rear each pipe be merged into one supervisor on, simultaneously by this pipe access planning exhaust system in, Specification Design pressed by vapor pipe, it along main building highest point dilution discharge, or should introduce the waste gas hoistway of neighbouring building nearby.Discharge adopts air inducing injection.
Ozone and activated carbon adsorbs: ozone and activated carbon process waste gas, remove repugnant substance in waste gas by the absorption of gac and ozone oxidation acting in conjunction, foul smell passes through activated carbon filtration adsorber with the flow velocity of 0.4m/s, wherein use the gac of 4 ~ 6 objects, thickness 100mm, can the organism such as hydro carbons be removed, remove stench by ozone oxidation later.Centrifugal blower model, power, to determine according to design.
The sewage containing pathogenic agent, heavy metal, sterilizing agent, organic solvent, acid, alkali and radioactivity etc. that hospital produces.Mud refers to the mud that produces in Hospital Sewage Treatment process and septic tank sludge.Function, the facility of all departments of hospital are different with composition of personnel situation, produce the main department of sewage and facility has: consulting room, laboratory, ward, laundry, X-ray are taken pictures the drainings such as developing and printing, Animal House, isotope therapy diagnosis, Operation theatre; The sanitary sewage of hospital's administrative control and medical worker's discharge, dining room, quarters for the single, family dependents' dormitory draining.Sewage composition and the water yield of the generation of section office of different department are different, as heavy metal wastewater thereby, oily(waste)water, developing and printing waste water, radioactive wastewater etc.And the sewage that different properties hospital produces also has a great difference.The more general sanitary sewage emission behaviour of hospital sewage is complicated.Hospital sewage source and complicated component, containing pathogenic microbes, poisonous, harmful physical chemistry pollutent and radiocontamination etc., there is the features such as space-pollution, acute infection and latent infection, important channel and the serious environment pollution of an epidemic disease diffusion can be become without effective process.Hospital sewage is subject to the pathogenic microbes such as ight soil, infective bacterial and virus and pollutes, and has infectivity, can induce an illness or damage.Whole Process Control principle.The whole process of produce hospital sewage, process, discharging controls.Forbid the sewage of hospital and dirt arbitrarily to be thrown aside to enter water drain.For preventing the pollution and harm in hospital sewage course of conveying, must treatment in situ in hospital.Hazardous and noxious substances in effective removal sewage, reduces disinfection byproduct (DBP) in treating processes and produces and control too high chlorine residue in water outlet, safety of preserving the ecological environment.
According to current standards, existing hospital sewage processing process rank is low, mainly there is concentration of suspension high, affects sterilisation effect; Variation water quality is large, and sterilizing agent dosage is difficult to control; Disinfection byproduct (DBP) generation is large, the safety of influence ecological environment; Chlorine residue standard no maximum, the problems such as too much chlorine residue harm ecological safety.
Hospital sewage water quality is similar to sanitary sewage, but complicated.As sterilizing agent, from heavy metal, the organic reagent of chemical examination, inspection, operation Deng Ge section office, and possible radio isotope etc.As hospital, containing a large amount of toxic chemical substance and various pathogens, virus and parasitic ovum in the sewage of its discharge.They have certain adaptive faculty in the environment, have even in sewage the survival time longer, if untreated or deal with improperly namely enter water body or for irrigate, will pollute the environment, affect the healthy of people.
