Abstract
A printing-dyeing sewage treating tower using oxygen-enriched gas features that the hollow biologic-film balls containing a small ball in it is used for its filler layer for higher specific surface area and porosity, its water washing mode is to input water via multiple channels for proportionally regulating the load of eacy tower layer easily, and its biological oxidizing mode is alternative conducting in air and sewage. Its advantages are low cost, high adaptability and easy operation.
Description
Technical field
The present invention relates to a kind of method of disposing of sewage, especially a kind of dyeing and printing sewage treating column that uses oxygen rich gas.
Background technology
The method of disposing of sewage in the prior art has multiple, for example: its shortcoming of biological filtering tower combined working is that the suspended substance and the oleaginousness of sewage is difficult for too high, the concentration of BOD is generally 200mg/L, excessive concentration is easily stopped up and is caused filler to lose efficacy, principal element is that filler is materials such as rubble, slag, gravelly sand, slag, haydite, waved plate, honeycomb, and specific surface area is up to 190m
2/ m
3High voidage is 90%, water flow mode is the method for spray, the sewage of ejection falls into and sewage is freely fallen pass through filler, microbial film on the filler is short action time, current are inhomogeneous, and all surfaces of filler is long-pending can not to be made full use of, and the surface-area utilization ratio is low, processing efficiency is low, the concentration of disposing of sewage is low, and use range is restricted, not the foreign material of easy to clean obstruction, obstruction reaches certain degree, the filler handling failure causes and can't move, and the filling adsorption that filterableness is good is little, shortcomings such as hole Xiao Yi obstruction.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned existence and design a kind of dyeing and printing sewage treating column that uses oxygen rich gas, adopt biological membrane ball to make filler, filter tower is an equipment, solves blockage problem, improve dispose of sewage concentration and efficient, simple in structure, floor space is little, easy construction, easy to operate, expense is low, and is strong to sewage quality water yield adaptability, and the water flow mode of sewage adopts top water inlet and bottom water inlet to constitute.
The technical solution adopted for the present invention to solve the technical problems is: biological membrane ball is a filler, change the water flow mode of general biological filtering tower combined working, biological membrane ball is that the two ends relative position of hollow ball partner sphere diameter is provided with a pair of hole of handling up, the handle up center of circle in hole is by the hollow ball diameter, hollow ball interior arrangement slightly larger in diameter is carried out counterweight in several counterweight beads in hole, increase the specific surface area of filler, make the melikaria that 0.5mm-10mm adds height on the whole surface of hollow ball, the biological membrane ball specific surface area is by melikaria, in the hollow ball, outside surface, counterweight bead outside surface constitutes, and specific surface area is 350m
2/ m
3-500m

3Biological membrane ball is with the motion of sewage water (flow) direction, and the hole of handling up has sewage to enter.Entering hollow ball inner utilization internal surface knot then hangs outside the microbial film, the sewage and the counterweight bead that enter hollow ball inside play counterweight jointly, make microbial film spheroid weight/power ratio in the sewage be slightly larger than the buoyancy of sewage, so that keep water static state then to sink, the hydrodynamic(al) attitude is then cursory, biological membrane ball rises and falls up and down freely in water with flowing of water and moves about, under the pressure of current, make, the sewage of spheroid inside is by the normal replacing of the aperture of handling up, keep the bulkiness between biological membrane ball, gap between biological membrane ball is moving about and change with spheroid, the aged microbial film is easily come off, aging microbial film floats along current, the difficult obstruction, and biological membrane ball is according to placing 0.8-0.9m in every m3 volume.The density of filler is put into container, have the advantages that filterableness is good and adsorptivity is strong, the structural shape of biological membrane ball is that sphere is a kind of big external force geometrical shape of bearing, the ball wall approaches the intensity height, it is little to take in the container volume, the porosity of biological membrane ball is more than 93%, guarantees the residence time of sewage, improves the clearance of concentration.Water flow mode of the present invention is made of top water inlet and bottom water inlet two portions, the top water inlet is by the first floor shower sewage to be sprayed, enter container after the filtration of sewage through the carrier biofilm ball, wastewater level progressively raises in the container, when water level reaches biological membrane ball and all invades height in the sewage, the connection of siphon pipe air emptying current enters lower floor's shower and successively supplies water, because the flow of lower floor's shower is greater than the flow of first floor shower, flow rate of water flow increase in the container flows to siphon pipe water-in direction, the biological membrane ball motion strengthens, to lower floor ejection current is that water level in the container descends gradually, sucking the air current up to siphon pipe only is broken as, microbial film is exposed to fully and directly absorbs oxygen in the air, and biological membrane ball was controlled by the capacity of first floor spray flow and siphon pipe delivery flow and container in the bubble time of invading of air and sewage.First floor spray sewage accumulates in container once more, water level is raise enter next circulation.The bottom water inlet is to be made of the two-way water pipe, one the tunnel is directly to be drawn by upper hose to enter each tower layer lower curtate water inlet pipe, another road is that each floor is drawn by the upper strata siphon pipe and entered lower floor's tower bottom water inlet pipe after two floor, regulate water inlet ratio in top and the bottom according to sewage quantity and load condition by gate, the load of each interlayer is to reach best effect.The water outlet of bottom water inlet pipe and the same angle of wall of container device and towards bulkiness, be beneficial to organism and airborne oxygen penetrates in the microbial film, microbial film fully contacts with sewage, microbial film is breathed in air and is invaded the abundant nutrition of adsorb organic compound acquisition in the sewage, and the objectionable impurities in the sewage obtains decomposing oxidation and reaches the purpose of purifying waste water.
The invention has the beneficial effects as follows: technology is short, effective, cost is low, easy to operate, the difficult obstruction, and little, the easy construction of floor space is strong to sewage quality water yield adaptability.The present invention is widely used in industries such as butchering sewage, food sewage, beer, chemical industry, pharmacy, printing and dyeing, papermaking wastewater and municipal sewage treatment.
