Embodiment
Referring to Fig. 1, the utility model comprises between ozone preparation 1, ozone contact tank 2, lift pump room 3 and biological activated carbon filter 4, in this ozone contact tank 2, be provided with pectination, (purpose is the flow process that increases sewage to several flow deflectors 8 of inserting up and down, thereby prolong the duration of contact of sewage and ozone), between adjacent flow deflector 8, respectively be provided with ozone shower nozzle 7, be respectively equipped with sewage inlet 6 and ozone contact tank outlet 9 at the two ends of this ozone contact tank 2.1 is connected with each this ozone shower nozzle 7 respectively by ozone pipeline 5 between the preparation of this ozone, and this ozone contact tank outlet 9 is connected with the inlet 12 of the water-distributing device of described biological activated carbon filter 4 by lift pump room 3 interior lift pumps 10.
Described biological activated carbon filter 4 comprises pond body 20, water-distributing device 13, filter and back up pad 14, distribution device 15, gas inlet 16, carbon leaching material layer 17, purify waste water water receiving tank 18 and wash-down water water receiving tank 19, be disposed with water-distributing device 13, filter and back up pad 14, distribution device 15 and carbon leaching material layer 17 in pond body 20 from bottom to up, the described water-distributing device inlet 12 of this water-distributing device 13 and the gas inlet 16 of distribution device 15 all pass outside this pond body 20; Be provided with the wash-down water water receiving tank 19 and the water receiving tank 18 of purifying waste water in the outside of the upper port of this pond body 20.This water receiving tank 18 of purifying waste water is located at the outside of wash-down water water receiving tank, and the top, outer of this wash-down water water receiving tank 19 is lower than the top, outer of the water receiving tank 18 of purifying waste water, and is higher than the upper end of pond body 20.Be respectively equipped with wash-down water outlet 22 (valve is housed) and treated water outlet 23 (valve is housed) in the bottom of this wash-down water water receiving tank and the water receiving tank of purifying waste water.
Inlet 12 at water-distributing device is connected to flushing water-in 24 (valve is housed), is connected to flushing inlet mouth 25 (valve is housed) at aeration inlet 16.Filter and back up pad 14 are made of a plurality of filters that branch is laid on the back up pad.
Water-distributing device 13, distribution device 15 and filter and back up pad 14 are prior art.
Described biological activated carbon filter material layer 17 be with common granulated active carbon as a kind of filler, utilize the huge specific surface area of gac, for microorganism in the water provides the carrier of depending on for existence, make microorganism in activated carbon surface growth, breeding.System's initial operating stage, microbial biomass is less, and it is less that activated carbon surface is hung modulus, and the removal of water pollutant mainly is the adsorption of gac.After operation for some time, activated carbon surface is hung modulus to be increased gradually, and the organism in water amount increases, and when microbial film was ripe, the removal of pollutent mainly was the Degradation of microorganism in the water body, and this moment, gac was biological activated carbon.And the common gac that general water treatment is used, only with gac as adsorption medium, utilize the adsorption of gac, remove the pollutent in the water.Ozone is a kind of strong oxidizer, and oxidation potential is 2.07V, but the fast and produce in situ of speed when reacting with organism, and raw material is easy to get, and is easy to use, do not produce secondary pollution.Ozone can react with the pollution substance (dissolving, suspension, colloidalmaterial and microorganism etc.) that various forms in the water exist, and the organism of complexity is transformed into simple organic, makes polarity, biological degradability and the toxicity etc. of pollutent change unnecessary O
3Can be decomposed into O voluntarily

The biological activated carbon technology is removed mechanism of pollutants and is mainly contained two aspects: charcoal absorption effect and microbial process.At initial operating stage, charcoal absorption has been played important effect to pollutant removal, and gac is the dissolved organic matter in the planar water rapidly, the microorganism in simultaneously also can enrichment water.Prolongation along with the time, the adsorption meeting weakens gradually, microbial process will dominate, the large amount of organic of activated carbon surface absorption also provides good living environment for microorganism, microorganism is growth, the breeding that nutriment carries out self with the organism under the abundant dissolved oxygen environment having, reduced pollutant load simultaneously, purifying water body.
The utility model is the technology of one according to gac physical and chemical adsorption, ozone chemistry oxidation and oxidation degradation, hardly degraded organic substance enters biological activated carbon filter after being oxidized by ozone into easily biodegradable organics in the sewage, carries out organic further removal.Be suitable for polluted river water, the improvement of lake, little pollution river, also can be used for high-quality regeneration waterworks construction.Can be applicable to engineerings such as moisturizing purification of water quality, the purification of river and lake water quality original position.Working process of the present utility model is described as follows:
Pending sewage enters ozone contact tank 2 from sewage inlet 6, and in ozone contact tank 2 with after the ozone that is discharged by ozone shower nozzle 7 contacts mixing, pump into biological activated carbon filter 4 (from the water inlet of biological activated carbon filter 4 bottoms, water-distributing device 13 can make sewage evenly enter biological activated carbon filter) with lift pump 10.Carbon leaching material layer 17 above filter and back up pad 14 is a granulated active carbon, and water inlet back carbon leaching material layer 17 expands, and pollutants in sewage is adsorbed and purified.Water after the processing is collected the back discharging by the water receiving tank 18 of purifying waste water.
Operation for some time need wash biological activated carbon filter 4, the specific operation process of flushing is: when the filter tank need be washed, at first close valve, the treated water outlet 23 of water-distributing device inlet 12, the valve of aeration inlet 16, the valve of opening wash-down water outlet 22 then carries out draining, when body 20 median water level in pond are reduced to flushing water level D1, open the valve of flushing water-in 24 and flushing inlet mouth 25, air water is carried out in the filter tank unite flushing.After wash-down water was collected by wash-down water water receiving tank 19, the sewage inlet 6 that is transported to system front end by wash-down water outlet 22 and wash-down water outflow pipeline 21 was handled again.The aeration rate of normal processing process need is little, and the aeration rate in when flushing is big, determines according to test.
The advantage of above-mentioned flushing is:
(1) flushing of precipitation position has reduced wash-water pump and the required pressure of flushing blower fan because the filter tank median water level reduces, and has saved the energy.
(2) flushing of precipitation position at first reduces the filter tank median water level; for gac provides expansion area; make that gac rolls, rubs with the lower section at ordinary water-level in the recoil process; microbial film is broken away from; the microbial film that comes off is with the wash-down water outflow system; this process has reduced the friction probability of gac and upper strata catch net, reduces the wearing and tearing and the loss of gac.
