Description
Technical field
The utility model relates to a kind of BAF, is the improvement of existing BAF structure, belongs to dirty technical field of waste water processing, is suitable for especially using when city sewage deep treatment.
Background technology
BAF is a kind of form of distortion of ordinary biofilter, also can regard a kind of special shape of biological contact oxidation process as.Its technological principle is, the less particulate filler of a certain amount of particle diameter of filling in the filter tank, the filling surface microbial film of growing, the inner aeration in filter tank, effluent stream through the time, utilize on the filler the strong oxidative degradation ability of high-concentration biological film amount that sewage is carried out fast purification, utilize crown_interception between small particle size filler to remove suspended substance in the water simultaneously, reach the purpose of purification.BAF is generally upflowing at present, adopts the mode of bottom aeration, and the bottom aeration requires gas blower pressure big, and energy expenditure is big, disagrees with the aim of energy-conserving and environment-protective, does not meet the requirement of Sustainable development.
The utility model content
The purpose of this utility model is to overcome the too high problem of prior art aeration energy consumption, by the structure and the operation scheme of existing BAF are improved, release that a kind of treatment effect is good, the BAF of consuming little energy, operation simple possible.The utility model combines the characteristics of kinds of processes such as traditional biological filter tank, Inka aeration theory, activated sludge process, has that floor space is little, effluent quality good, treatment process is short, capital construction and advantages such as working cost is low, easy handling management.
The technical solution that the utility model provides is: this BAF mainly includes the pond body, filler, the filler plate washer, aeration water-distributing device part, be characterized in the body of described pond light filler being housed, the top of light filler is provided with the filler baffle plate, the top of this filler baffle plate is provided with class activated sludge process district, the top of described pond body is provided with back flushing water inlet pipe and water inlet pipe, the bottom of pond body is provided with the back flushing rising pipe, the bottom of pond body is provided with rising pipe, this rising pipe is provided with the water outlet filter, also be provided with the gas main that aeration is used on the body of described pond, gas-distributing pipe in the gas main is connected with the inlet pipe in the packing layer that is arranged on body middle and upper part, pond, this inlet pipe is provided with aeration head, another gas-distributing pipe in the gas main be arranged on body middle and lower part, pond packing layer and be connected with back flushing inlet pipe between the rising pipe, also be provided with aeration head on this back flushing inlet pipe.
Principle of design of the present utility model is: according to Inka aeration theory (Inka aeration) promptly: bubble only forms with broken at it has the highest oxygen transfer rate in a flash, and highly irrelevant with its moving in liquid
[1]The utility model adopts the light filler of proportion less than water, prevents that by the filler baffle plate filler runs off, and makes filler be in compaction state simultaneously under self buoyancy, aerating apparatus is located at apart from about the following 1m of rate material baffle plate, by the aeration head gas distribution, contact with following current to stream, give the water body oxygenation.Because aerating apparatus is arranged at body top, pond, the required pressure of gas blower reduces greatly, thereby can save a large amount of energy consumptions, reaches the purpose of energy-conserving and environment-protective.
Compared with prior art, the beneficial effects of the utility model are: good, the remarkable energy efficient of effluent quality.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Number in the figure: 1. back flushing water inlet pipe, 2. water inlet pipe, 3. rising pipe, 4. back flushing rising pipe, 5. filler baffle plate, 6. gas main, 7. inlet pipe, 8. back flushing inlet pipe, 9. aeration head, 10. water outlet filter, 11. pond bodies, 12. fillers, 13. class activated sludge process districts.
Embodiment
As shown in the figure, this BAF mainly includes pond body 11, filler 12, filler plate washer 5, aeration water-distributing device part, in the described pond body 11 light filler 12 is housed, the top of light filler 12 is provided with filler baffle plate 5, the top of this filler baffle plate 5 is provided with class activated sludge process district 13, the top of described pond body 11 is provided with back flushing water inlet pipe 1 and water inlet pipe 2, the bottom of pond body 11 is provided with back flushing rising pipe 4, the bottom of pond body 11 is provided with rising pipe 3, this rising pipe 3 is provided with water outlet filter 10, also be provided with the gas main 6 that aeration is used on the described pond body 11, gas-distributing pipe in the gas main 6 is connected with the inlet pipe 7 in being arranged on pond body 11 middle and upper part packing layers, this inlet pipe 7 is provided with aeration head 9, another gas-distributing pipe in the gas main 6 be arranged on pond body 11 middle and lower part packing layers and be connected with back flushing inlet pipe 8 between the rising pipe 3, also be provided with aeration head 14 on this back flushing inlet pipe 8.
Working process of the present utility model is:
Running status: former water enters pond body 11 through water inlet pipe 2, and filler 12 is at buoyancy of water effect float downward, because filler baffle plate 5 stops that filler is compacted in the body of pond.Pressurized air enters water body through inlet pipe 7 by aeration head 9 by gas main 6 and contacts with water, gives the microbial film oxygen supply on water body and the filler.Filler baffle plate top keeps the water level of certain depth of water, and suspended substance of holding back and part biological film fully contact with water body under gas stirring, forms class activated sludge process district 13.Water after the filler 12 of flowing through is handled is collected through rising pipe 3 by water outlet filter 10 and is discharged.
Back flushing state: after opening back flushing rising pipe 4, the wash water of head-tank enters pond body 11 through back flushing water pipe 1, filler 12 is fluidized state under current drive, 12 suspended substances of holding back of filler and part biological film are discharged from the recoil rising pipe with current, stop Inlet and outlet water, pressurized air enters water body through back flushing inlet pipe 8 by aeration head 14 by gas main 6, filler is compaction state under buoyancy and air push, stop the supple of gas or steam, intake, so repeatedly several times, too much microbial film obtains removing on the filler, and system can put into operation again.
