Description
Technical field
The utility model belongs to sewage disposal, field of environmental biotechnology, relates to a kind of biological activated carbon filter.
Background technology
Aerated biological activated carbon filter tank treatment technology can be widely used in various industrial sewage, the process of municipal sanitary sewage and the improvement of rivers and lakes environmental wastewater, the high concentration organic sewage that especially cannot process traditional method and the cold rolling wastewater of high-ammonia-nitrogen sewage have unique treatment effect, have filled up blank with the cold rolling wastewater of biochemical process process high concentration organic sewage and high-ammonia-nitrogen sewage both at home and abroad.At present at oil, petrochemical industry, chemical industry, leather, coking (gasification), food, brewage, daily use chemicals, printing and dyeing, bio-pharmaceuticals, successful Application in all eurypalynous sewage disposals such as papermaking and city domestic sewage.The porosity characteristic of gac, makes it have very large specific surface area, and very strong adsorptivity, take gac as carrier, and surface attachment microorganism, effectively extends adsorptive power and the regeneration period of gac.But the shortcomings such as current aerated biological activated carbon filter tank also exists, and biological activated carbon filtering layer easily condenses, gas blocks up, the utilization ratio of oxygen is not high, energy consumption is high, biological activated carbon easily loses, need further to be improved.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of aerated biological activated carbon filter tank.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of aerated biological activated carbon filter tank of the utility model, comprise main box and upper box, the diameter of upper box is greater than main box, and upper box is fixed on main box top by strengthening gusset, be provided with into water water distributor and aerofoil profile drainage tray in upper box, the side of upper box is provided with backwash water port; Be disposed with biological activated carbon filtering layer and cobble supporting layer in main box from top to bottom, in biological activated carbon filtering layer, be provided with aeration inlet pipe, in cobble supporting layer, be furnished with water shoot and backwash inlet pipe.
Further, the diameter of cobble supporting layer foundation cobble can be divided into three layers, the cobble that cobble is formed, third layer is 4 ~ 8mm by diameter that the cobble that wherein orlop is in 16 ~ 32mm by cobble diameter is formed, the second layer is 8 ~ 16mm by diameter is formed.The volume ratio of the first layer, the second layer and third layer is 6:5:2.
Waste water enters aerated biological activated carbon aerating filter, through water shoot device for transferring after the purifying treatment of biological activated carbon filtering layer and the filtration of cobble supporting layer by water inlet water distributor; Adopt air-water to replace associated form and backwash is carried out to aerated biological activated carbon aerating filter, backwash air inlet is entered by backwash inlet pipe, backwash water inlet is entered by water shoot, backwash draining by aerofoil profile drainage tray by equipment side water port device for transferring outward and introduce trench.Due to wide structure narrow under aerofoil profile drainage tray, the loss with backwash water of biological activated carbon and microorganism effectively can be stopped.
Compared with prior art, the utility model has the following advantages:
One, adopt water to dirty, the parallel design to upper reaches of aeration, make to bring about the desired sensation, water carries out fabulous even, prevent bubble to condense in biological activated carbon gentle stifled phenomenon, the utilization ratio of oxygen is high, and energy consumption is low;
Two, adopt the design of aerofoil profile drainage tray, can effectively prevent biological activated carbon and microorganism with the loss of backwash water;
Three, volume of equipment and floor space little, floor space and initial cost can be saved;
Four, this device structure is simple, and stable and reliable operation, treatment effect is better.
