Preferably, described aeration tube, sewage water inlet pipe, backwash pipe and recoil tube are installed in packing layer III and/or packing layer IV.
Preferably, in described packing layer I, filler is specially haydite or gac; In described packing layer II, filler is specially haydite or gac; In described packing layer III, filler is specially quartz sand; In described packing layer IV, filler is specially cobble.
The beneficial effects of the utility model are:
1. cancel the setting of second pond, owing to needn't establishing second pond, reduced volume and the initial cost in pond;
2. be used to injecting the arm of microbial preparation, microbial preparation and gac and haydite mixed fillers are coexisted, effectively the hard-degraded substance in Decomposition Wastewater;
3. capacity of resisting impact load is strong, without the sludge bulking problem; Soon, initial failure period is short for easy to be filmed, startup.
The accompanying drawing explanation
The utility model has accompanying drawing 1 width.
Fig. 1 is novel aerated biological activated carbon filter tank schematic diagram.
In the drawings: the 1-arm; The 2-sewage water inlet pipe; The 3-recoil tube; 4-backwash pipe; The 5-aeration tube; The 6-rising pipe; 7-filter tank body; 8-packing layer I; 9-packing layer II; 10-packing layer III; 11-packing layer IV.
Embodiment
As shown in the figure, a kind of novel aerated biological activated carbon filter tank, comprise filter tank body 7, in filter tank body 7 inside, stack gradually packing layer I 8, packing layer II 9, packing layer III 10 and packing layer IV 11 from top to bottom, body 7 bottoms in filter tank pass into aeration tube 5, sewage water inlet pipe 2, backwash pipe 4 and recoil tube 3 from top to bottom successively, sewage water inlet pipe 2 forms by main with from main branch water distributor out, inlet end at sewage water inlet pipe 2 has an arm 1 be used to injecting microbial preparation, and body 7 tops in filter tank set out water pipe 6.
Preferably, described aeration tube 5, sewage water inlet pipe 2, backwash pipe 4 and recoil tube 3 are installed in packing layer III and/or packing layer IV.
Preferably, in described packing layer I, filler is specially haydite or gac; In described packing layer II, filler is specially haydite or gac; In described packing layer III 10, filler is specially quartz sand; In described packing layer IV 11, filler is specially cobble.
During use, waste water is distributed into water distributor by pump by sewage water inlet pipe 2 and from bottom, squeezes into the aerated biological activated carbon filter tank, and the bed of packings that water is flowed through from bottom to top and arranged by cobble, gac and haydite classification, add microbial preparation from arm 1 simultaneously.When effluent stream was crossed bed of packings, at first pollutent was filtered and adsorbs, and became the nutraceutical matrix of microbial strains, made dielectric surface form microbial film.Microbial film is further " capturing " matrix again, by its assimilation, metabolism, degraded.Therefore the aerated biological activated carbon filter tank can, in degradation of organic substances, have the effect of biofloculation, absorption and filtration.And because microbial film is attached on filtrate, activity is very high, and microbial film is not limited by mud age, and is very favourable for the degraded of pollutent.Carrying out along with treating processes, the suspension active sludge that is trapped between the filtrate gap has formed sludge filtering layer, the organic while in oxidative degradation sewage, played further absorption and filteration, thereby made organism and suspended substance all can obtain removing more thoroughly.In the bottom of reactor, the heterotroph microorganism is dominant bacteria, and Prevent Carbon Contamination thing (CODcr, BOD5 and SS) mainly here is removed, and on reactor top, autotroph, preponderate as nitrifier, and ammonia nitrogen is by nitrated.In microbial film inside, and the gap between the part filler, in a large amount of active sludge of accumulating, exist aerobic-anaerobic microbe, in the aerated biological activated carbon filter tank, the removal of Prevent Carbon Contamination thing can occur therefore, the function of nitrification and denitrification is arranged simultaneously.In the operational process of filter tank, along with biomembranous metabolism, the impurity of holding back on the microbial film that comes off and filtrate constantly increases, and in filtrate, head loss increases, and need carry out back flushing to filtrate to the certain period.The aerated biological activated carbon filter tank using its filter after water outlet as backwash water, separately do not establish the recoil pond, backwashing wastewater is back to the coagulation facility by water shoot.
The microbial preparation that the arm be used to injecting microbial preparation described in the utility model injects can be any one microbial preparation or its combination of can be applicable to wastewater treatment.In actual use, the contriver has selected following preparation: (1) syBIO1240 possesses the gas chromatography degradation capability, can be applied to various industrial sewage and process.In microbial mixture, contain some bacterial strains, can decompose hydrocarbon polymer, comprise Mierocrystalline cellulose, tensio-active agent, phenolic compound, ketone and not labile organism, and have the salt tolerant characteristics.Suggestion utilizes the microorganism active of syBIO1240 to improve trade effluent COD clearance.(2) syBIO1270 is a kind of by Nitrosomonas and these 2 kinds of liquid form mixts that nitrated bacterial strain forms of bacterium nitrobacter.This product is applicable to the aerobic treatment system, and successfully in active sludge, wastewater lagoon and the modified version physical/chemical device in the places such as municipal administration, refuse landfill, Steel Plant, refinery, food-processing/extraction plant, chemical preparations factory, produces nitrification.Above-mentioned two kinds of microorganism reagents are the product on sale of Dalian source of students water treating equipment Development Co., Ltd.
Technical characteristics of the present utility model is:
1. filler biological charge capacity, volumetric loading increase, and needn't establish volume and initial cost that second pond has reduced pond;
2. the air water relative movement improves the utilization ratio of oxygen, and porous filler increases air water and biomembranous contact area, thereby has improved treatment effect;
3. have the synergy of absorption-decomposition-regeneration, and have huge surface energy and specific surface area, nitrification efficiency is high, and denitrification effect is good;
4. adopt high-efficiency microorganism preparation and gac and haydite mixed fillers to coexist, effectively the hard-degraded substance in Decomposition Wastewater;
5. capacity of resisting impact load is strong, and without sludge bulking problem easy to be filmed, startup soon, initial failure period is short;
The utility model is not limited to above-described embodiment, and any equivalent concepts or change in the technical scope that the utility model discloses, all classify protection domain of the present utility model as.
