Background technology
Hospital sewage refers to that hospital (general hospital polyclinic, professional specialized hospital and other type hospital) is to the sewage of physical environment or urban duct discharging.Its water quality is different with different hospital's character, scale and its location.The sewage quantity of every sick bed discharging every day is about 200-1000L.Principal pollutant contained in the hospital sewage are: pathogenic agent (parasitic ovum, pathogenic bacteria, virus etc.), organism, floating and suspended substance, radioactive pollutant etc., contain in the undressed raw waste water bacterium total amount reach 10^8/more than the mL.
The water resources in china occupancy volume per person is few, and spatial distribution is uneven.Along with Chinese Urbanization's, industrialized acceleration, the demand gap of water resources also increases day by day.Under such background, sewage treatment industry becomes new industry, and present and tap water production, water supply, draining, middle water reuse industry are in status of equal importance.Although because country and governments at all levels are to the improving constantly of environment protection attention degree, Chinese sewage treatment industry is just at rapid growth, the sewage disposal total amount increases year by year, and the town sewage processing rate improves constantly.But present Chinese sewage treatment industry still is in the primary stage of development.On the one hand, the present sewage treatment capacity of China does not still catch up with the rapid expansion of water scale, and the auxiliary facility construction such as pipe network, sludge treatment seriously lag behind.On the other hand, the wastewater treatment rate of China also exist obvious gap, and the rate of load condensate for the treatment of facility is low compared with developed countries.
The utility model content
The utility model has proposed a kind of new and effective hospital sewage treating apparatus for the problems referred to above, hospital sewage after treatment, and non-secondary pollution not only can meet and exceed the emission standard of national regulation, carries out second stage employ; Organic matter in the mud can be degraded in treatment unit fully, and mud is not needed to carry out special processing again.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of new and effective hospital sewage treating apparatus, its device mainly comprises grille well, equalizing tank, hydrolysis acidification pool, contact-oxidation pool, tube settler, sludge thickener, disinfecting tank, dechlorination pond.
Grille well one end is collected pipe network with hospital sewage and is connected, the other end is connected with equalizing tank, the equalizing tank the other end is connected with hydrolysis acidification pool, the hydrolysis acidification pool the other end is connected with contact-oxidation pool, the contact-oxidation pool the other end is connected with tube settler, the tube settler the other end is connected with disinfecting tank, and the disinfecting tank the other end is connected with the dechlorination pond.
Stationary grizzly is installed in the grille well; Be provided with lift pump in the equalizing tank; Combined stuffing is set in the contact-oxidation pool, and is provided with gas blower; Be provided with chlorine dioxide generator in the disinfecting tank, dechlorination is provided with dechlorination apparatus in the pond; Tube settler is other to be provided with return sludge pump, is connected with the bottom of tube settler, and the other end is connected with sludge thickener, and the other end of sludge thickener is connected with pressure filter.
The beneficial effects of the utility model are: by this waste disposal plant, guarantee that the water outlet indices reaches design requirements, reach or be better than emission standard; Adopt reliable in function, stable, simple to operate, operational management is the treatment process technology easily, reduces construction cost and processing cost to reach; Incorporation engineering condition and emission standard, careful choose reasonable engineering design plan (EDP), and adopt advanced technology, novel material, new layout as far as possible, and to reduce working cost, guarantee that the treatment system long-time running is safe and reliable, stable water outlet, up to standard secure; Rationally control noise and peculiar smell well, to avoid secondary pollution; Adopt machinery and automated operation, to alleviate operator's labour intensity.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the structural representation of the efficient hospital sewage treating apparatus of utility model.
1. grille wells among the figure, 2. equalizing tank, 3. hydrolysis acidification pool, 4. contact-oxidation pool, 5. tube settler, 6. sludge thickener, 7. disinfecting tank, 8. dechlorination pond, 9. grid, 10. lift pump, 11. combined stuffings, 12. gas blowers, 13. return sludge pump, 14. chlorine dioxide generator, 15. device for deoxidizing, 16. pressure filter.
Embodiment
As shown in drawings, the efficient hospital sewage treating apparatus of the utility model mainly comprises grille well (1), equalizing tank (2), hydrolysis acidification pool (3), contact-oxidation pool (4), tube settler (5), sludge thickener (6), disinfecting tank (7), dechlorination pond (8).
Sewage works is received in each outlet water outlet.
The sewage lifting of collecting is equipped with stationary grizzly (9) to grille well (1) in the grille well (1).Gravity flow enters equalizing tank (2) sewage is removed thick grain foreign material in the sewage behind grille well (1) after.Further process grid slag outward transport harmless treatment field.
The effect of equalizing tank (2) is homogenizing water quality, evenly the water yield; Guarantee the operation of subsequent treatment process steady and continuous.Equalizing tank (2) sewage promotes through lift pump (10) and enters hydrolysis acidification pool (3), inner at hydrolysis acidification pool (3), microorganism is mainly finished hydrolysis and two processes of acidifying, larger molecular organics is broken down into micromolecular organism in hydrolysis and product acid phase, thereby has improved the biochemical of sewage.Hydrolysis acidification pool (3) does not need airtight pond, does not need agitator, safeguards thereby reduce cost and be convenient to.Because hydrolysis acidification pool (3) has reduced sludge quantity to the degraded of solid organic matters, has the function of digester.
The water outlet of hydrolysis acidification pool (3) flows automatically to biological contact oxidation pond (4).This part is the core processing unit of whole device.Combined stuffing (11) is set in the contact-oxidation pool (4), and by gas blower (12) oxygen supply culturing micro-organisms, microorganism growth keeps the microorganism total amount to maintain higher level in the pond on filler.By the degraded of microorganism, the CODcr in the sewage, BOD
5, NH
3-N etc. are removed.Contact oxidation technology has the advantages such as capacity of resisting impact load is strong, operating load is high, stable.
Contact-oxidation pool (4) water outlet enters tube settler (5) from inflow and carries out solid-liquid separation, and tube settler (5) has load greatly than general settling tank, the advantage that sedimentation effect is good.Tube settler (5) water outlet gravity flow enters disinfecting tank (7), utilizes chlorine dioxide generator (14) that it is carried out sterilization and disinfection; Enter again dechlorination pond (8), utilize dechlorination apparatus (15) that it is carried out dechlorination and process, discharge again after treated water is up to standard.
When sludge quantity is more in the tube settler (5), is extracted into sludge thickener (6) with return sludge pump (13) and concentrates.Behind the certain hour, when sludge quantity is more in the sludge thickener (6), with dioxide peroxide mud is carried out germicidal treatment first, use again pressure filter (16) dehydration after, transport outward with other Hazardous wastes of hospital and to carry out harmless treatment.
Whole engineering all is automatically operation of automatic control device control, only needs the watchstander regularly to patrol and examine every day during operation and gets final product.
