Abstract
The utility model discloses equipment for treating and reusing industrial and urban wastewater, which combines the anaerobic reaction with aerobe connecting with oxidation, tilting plate precipitation, double-layer connect filtration and biological active carbon for integration, having novel and compact structure. The composition equipment for wastewater treatment adopts an anaerobe biological reaction unit in composite type of an anaerobic sludge bed and a packed bed, and the packing adopts the semi-soft packing. The organic pollutant, particularly the organic pollutant that is difficult to be biodegraded decomposes organic acid of small molecular through anaerobe, and can be biodegraded through aerobic microbes in an aerobic contact pool. The aerobic treatment unit adopts a biological contact aerobic process and honeycomb packing whose area is larger than the specific surface area, and the external (or the internal) aerobics supply equipment is arranged in the aerobic treatment unit.
Description
The utility model relates to a kind of device of handling trade effluent and sanitary sewage, is sewage is handled according to discharging and reuse standard.On equipment, adopt integrated and have assembly unit, take up an area of, reduce cost and working cost, applicable to different landform occasions thereby reduce.
At present, development along with industry and city, the sanitary sewage of the organic sewage of some midget plants and dispersion Residential areas (comprising hotel, hospital sewage) requires to reach discharging and reuse standard, particularly the sewage of some difficult for biological degradation need be handled and reach emission standard, for example Fang Zhi dyeing and printing sewage etc.Like this as set up independent sewage work, promptly uneconomical, management is difficulty also, and also acquires a certain degree of difficulty on handling.
It is few to the purpose of this invention is to provide a kind of occupation of land, the waste disposal plant that efficient is high, and it not only can handle common sanitary sewage, but also can handle the industrial sewage that is difficult to degrade.
The present invention is achieved in that sewage is precipitating, before aerobic oxidation, the filtration treatment, at first carry out anaerobic reaction, make to be difficult to biodegradable organic pollutant and to be decomposed into micromolecular organic acid, be beneficial to organic pollutant and in the aerobic oxidation process, be degraded by anerobe.
Because adopt above-mentioned sewage treatment process, apparatus of the present invention can be handled the organic sewage of higher concentration.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is an outside vertical planning drawing of the present utility model
Fig. 2,3 is respectively A-A, the B-B of the utility model vertical planning drawing, sectional view.
See figures.1.and.2, sewage disposal integration organization device is a container by carbon steel processing, and two ends are the aerobic contact oxidation pond (9) that a semicircle is equipped with filler.The centre is the rectangle steel cabinet, is separated into anaerobic composite bed reaction tank (2), inclined-plate clarifying basin (14), double layer filter (21) and the biological activated carbon reaction tank (27) of band filler in the steel cabinet by steel plate.
It is the B-B sectional elevation of Fig. 1 with reference to Fig. 3, can clearly be seen that from figure the utility model is to implement like this, sewage enters anaerobic composite bed reaction tank (2) by the water distributor (3) of water inlet pipe (1) through anaerobic composite bed reaction tank (2) end, upwards by sludge blanket (4) and packing layer (5), enter effluent trough (7) by V-notch weir (6) then, enter aerobic contact tank (9) by pipeline (8).Organism in the sewage under the condition of aerobic by the microbiological oxidation metabolism.Sewage upwards flows into effluent trough (12), the bubble that sewage is carried under one's arms is overflowed, mud enters inclined-plate clarifying basin (14) by the narrow slit (13) on contact-oxidation pool and the settling tank common wall in sewage and the water, particulate matter in the sewage is upwards sinking to bucket (15) by gravity in the process of flowing, sewage is by sloping plate deposition (16) time, the fine particle thing further is deposited on the swash plate, finally slips into bucket.Sewage rises through swash plate after clear water zone (17) imports water leg (18), pass through force (forcing) pump (19) again and enter double layer filter (21) by water inlet pipe (20), water is downward through the coal seam filter material layer (22) and the sand filtration bed of material (23) and gravel and bears layer (24) on the warp in the filter tank, enter biological activated carbon pond (27) by the header (25) of the bottom rising pipe (26) that flows into top, filter tank that confluxes, in the charcoal pond, flow through from top to bottom active carbon layer (28) and bear the layer (29), under the condition of bottom perforated pipe gas distribution (30), oxidized by the organism of charcoal absorption, metabolism.Sewage is finally collected by the header of bearing under the layer (31) after treatment, at last by rising pipe (33) discharger, and discharging or reuse after sterilizing.Overflow port (34 or 35) is left when overflow port begins overflow in filter tank and charcoal pond on top, can open outside gas valve (36 or 37) and close intake pump, undertaken air purge 2-3 minute by header, close gas check valve then, open force (forcing) pump (two) and recoil, backwashing water enters water drain in the factory by water shoot (38 or 39) by entering pipe (40 or 41).
Claims (3)
1, a sewage disposal and reusing integral treatment unit of forming by the living oxidation of anaerobics, aerobe oxidation, sloping plate deposition, double-deck contact percolation and charcoal filtration, it is characterized in that collecting the anaerobic composite bed reaction tank, (2), aerobic contact oxidation pond (9), inclined-plate clarifying basin (14), double layer filter (21) and biological activated carbon pond (27) are one.
2, by the sewage disposal integrated assembly of claim 1 regulation, it is characterized in that the water inlet head end of anaerobism complex reaction pond at this treatment process.
3,, it is characterized in that the double layer filter in the device and the order of work in biological activated carbon pond can exchange by the sewage disposal integration organization device of claim 1 regulation.
