Abstract

The utility model relates to an integrated biochemistry processor for sewage, comprising an external cylinder body, an internal cylinder body, a nozzle, a surface aerator, semi-flexible packing, a honeycomb pipe chute with 60 DEG, a pipeline, and a valve. The integrated biochemistry processor for sewage organically combines the sections of oxygen supply, uplift, return sewage flow, and sewage separation in integration. The integrated biochemistry processor for sewage has the advantages of small ground occupation, having high processing efficiency, having low investment, and having convenient operation and management, can be used for the biochemical processing the small flow organic sewage.

Description

Integrated biochemistry processor for sewage

The utility model relates to a kind of low discharge organic sewage integral biological chemical processor, belongs to environmental protection equipment.

According to preliminary search, before the utility model is made, still there is not similar therewith equipment.In the domestic prior art, for the low discharge organic sewage (as disperseing little Residential areas sanitary sewage, pot foods sewage, butchering sewage, restaurant kitchen waste water, hospital sewage for a short time and give processing etc.) only with simple process ways such as septic tank, settling tanks, remove the weak effect of organic pollutant, and the saprobia chemical treatment method generally is used in the larger organic sewage treatment project.

The purpose of this utility model provides that a kind of treatment effect is good, floor space is little,, reduced investment few with material, the simple integrated sewage water biological chemistry of operational administrative treater, is applicable to effective processing of various low discharge organic sewages.

Main points of the present utility model are: the design of links such as oxygen supply, lifting, mud backflow, bio-contact oxidation, mud-water separation is as a whole, the function that has both activated sludge process and biomembrance process, an equipment is exactly complete one-level biological chemistry treating processes.

Below in conjunction with accompanying drawing the utility model is carried out detailed description:

Accompanying drawing---be structural map of the present utility model

The utility model is by outer cylinder body (1), inner barrel (2), thrust-augmenting nozzle (3), pump shape surface aeration machine (4), the axial cord spacing is the semi soft packing (5) of 140-160mm, the axial cord spacing is the semi soft packing (6) of 180-200mm, hoop arranges that the aperture is the honeycomb inclined-tube (7) of 30-50mm, ring-type effluent trough (8), water leg (9), water inlet pipe (10), vacuum breaker (11), water intaking valve (12), rising pipe (13), shore pipe (14), mud valve (15), offlet (16), water drain valve (17) is formed.Outer cylinder body (1) is made of two portions up and down, top is cylindrical, its top is a ring-type zig-zag overflow weir, the bottom is the rounding platform, both are integrally welded, the employing steel sheet is processed into, periphery, profile of tooth weir, outer cylinder body top is ring-type effluent trough (8), water outlet is confluxed to water leg (9), the water leg bottom picks out water pipe (13), one of the bottom of outer cylinder body (1) rounding platform side is equipped with water inlet pipe (10), vacuum breaker (11), water intaking valve (12), the opposite side of rounding platform bottom is equipped with shore pipe (14), mud valve (15), offlet (16) is equipped with in outer cylinder body (1) cylindrical portions may lower end, water drain valve (17), inner barrel (2) is the cylinder that is formed by steel sheet weldering system, in the ring-type interlayer between outer cylinder body (1) and the inner barrel (2), its underpart is equipped with semi soft packing (6) and is constituted to upper reaches bio-contact oxidation district, its top is 60 ° of honeycomb inclined-tube settling regions (7), it is straight tube that top is equipped with in the central position of biochemical treatment equipment, the bottom is bell-mouthed thrust-augmenting nozzle (3), at liquid level position pump type surface aeration machine (4) is housed on the thrust-augmenting nozzle top, semi soft packing (5) is housed in the ring-type interlayer between inner barrel (2) and the thrust-augmenting nozzle (3) constitutes to dirty bio-contact oxidation district.

Principle of work of the present utility model and working process: sewage is promoted by water inlet pipe valve (10) (11) (12) by pump and enters biochemical treatment equipment, the lifting force that is produced when being turned round by pump type surface aeration machine (4) is introduced thrust-augmenting nozzle (3) with the active sludge and the sewage of biochemical treatment equipment bottom, fully mixed in thrust-augmenting nozzle, and be promoted to liquid level diffusion, utilize the effect of surface aeration machine, promoting, diffusion, sewage obtains necessary oxygenation in the process that liquid level is brought in constant renewal in, the mixed solution that diffuses to liquid level from top to bottom passes through semi soft packing (5) promptly to dirty bio-contact oxidation district, current transfer upwards to pass through semi soft packing (6) promptly to upper reaches bio-contact oxidation district after crossing inner barrel (2) lower end, again upwards by honeycomb inclined-tube settling region (7), this moment, muddy water obtained separating, clarification back sewage is evenly excessive to ring-type effluent trough (8) on profile of tooth weir, outer cylinder body (1) top, discharge from rising pipe (13) again by water leg (9), the mud that the tube settling district holds back glides at any time, to the biochemical treatment equipment bottom, pass back into thrust-augmenting nozzle (3) by semi soft packing (6) again.When sludge concentration is too high in the mixed solution, can suspend surface aeration machine, do not advance sewage, static half an hour, open mud valve (15), the mud that is deposited to the bottom is discharged a part, till sludge concentration is suitable.The purposes that discharge tube valve (16) (17) is provided with is: 1, and usefulness regularly discharges water when cultivating active sludge; 2, when clearing up the deposition in tube settling district, can discharge water liquid level is reduced to below the settling region; 3, when the time out of service is longer, the sewage in bio-contact oxidation district can be discharged, so that contacting with air, microbial film keeps active.

The advantages such as the utility model is compared with existing low discharge organic sewage treatment technology, has the treatment process advanced person, and decomposing organic pollutant is effective; Compare with general biochemical processing process, have structure compact and reasonable, volumetric loading height, cultivate that microorganism is convenient, floor space is little, few with material, reduced investment, upper detective, operational administrative and the advantage such as easy to maintenance.

The utility model can be designed to the series equipment of different disposal ability, as the needs of Product supply society.
