Description
Technical field
The utility model relates to a kind of Hospital Sewage Treatment field of purification, especially a kind of Hospital Sewage Treatment purification system.
Background technology
The sewage of hospital, except general sanitary sewage, also containing chemical substance, radioactive wastewater and pathogenic agent, could discharge after having to pass through process, just must can discharge, require that sewage treatment facility will seal after sterilization.Hospital sewage refers to the sewage that hospital discharges to physical environment or urban duct; Its water quality is different with different hospital's character, scale and its location; Principal pollutant contained in hospital sewage are: pathogenic agent, organism, floating and suspended substance, radioactive pollutant etc., reach 108/more than mL in undressed raw waste water containing bacterium total amount.
The Novel state Waste Water Treatment that film-bioreactor (MembraneBio-Reactor, MBR) is membrane separation technique and biologic treating technique combination.Replace traditional biological treatment technology end second pond with membrane module, in bio-reactor, keep high reactivity sludge concentration, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.Active sludge in the membrane separation plant entrapping tank in aerobe pond and larger molecular organics are immersed in main utilization.In membrane bioreactor system, active sludge (MLSS) concentration can be promoted to 8000 ~ 10000mg/L, even higher; Sludge age (SRT) can extend to more than 30 days.Membrane bioreactor is because of its effective crown_interception, and can retain generation cycle longer microorganism, can realize deep purification of waste water, Simultaneous Nitrification bacterium can fully breed in system, and its nitrification effect is obvious, provides possibility to deep phosphorous removal denitrogenation.The general employing concrete constructions time is longer, and not easily seals.
State Environmental Protection Administration and national quality basicity inspection and quarantine general bureau combine in July, 2005 and have issued medical institutions' pollutant emission standard " medical institutions' water pollutions emission standard " (GB18466-2005); standard proposes comprehensive control overflow to the pollutent such as waste gas, mud that medical institutions' sewage, sewage works produce, and highlights the sterilisation effect containing pathogenic agent sewage.In sewage disposal, hospital sewage water quality is complicated.Containing a large amount of bacterium, virus, parasitic ovum and hazardous and noxious substances in sewage, what have may contain radioactivity.Hospital sewage is Synthetic Wards: sewage mainly.Existing design adopts bio-contact oxidation+precipitation+sterilization process, i.e. A/O art breading.The function of A/O technique is nitrification and denitrification effect.Its principle is by the effect of nitrification and denitrification bacterium, ammonia nitrogen in sewage is converted to nitrite nitrogen, nitric nitrogen, then by denitrifying bacteria effect, nitric nitrogen is converted to nitrogen, denitrogenation from sewage.Key points in design focuses on the sterilization and disinfection mode of sewage, mud.
Hospital sewage refers to the sewage of hospital (general hospital polyclinic, training specialized hospital, health clinics in towns and townships, infectious hospital and other type hospital, blood station, Disease Control and Prevention Center, community medical service center) to physical environment or urban duct discharge.Its water quality is different with different hospital's character, scale and its location.
Principal pollutant contained in hospital sewage are: pathogenic agent (parasitic ovum, pathogenic bacteria, virus etc.), organism, floating and suspended substance, radioactive pollutant etc., reach 108/more than mL in undressed raw waste water containing bacterium total amount.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.
