Among the figure: water inlet pipe 1, rising pipe 2, bio-carrier 3, compressed air inlet pipe 4, boring aeration pipe 5, tubular graticule mesh 6, reactor body 7, water tank 8.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment:
As shown in Figure 1, the aerobe reactor that is applied to sewage disposal that the utility model provides, comprise compressed air inlet pipe 4 and reactor body 7, it is characterized in that being provided with bio-carrier 3 in the described reactor body 7, reactor body 7 bottoms are provided with boring aeration pipe 5, and boring aeration pipe 5 is connected with compressed air inlet pipe 4; Reactor body 7 one sides are provided with water inlet pipe 1, and opposite side is provided with tubular graticule mesh 6; Be connected with water tank 8 on the tubular graticule mesh 6, a side of water tank 8 is provided with rising pipe 2.Described boring aeration pipe 5 is uniform distribution side by side in reactor body 7 bottoms.Institute's bio-carrier 3 is suspended in the reactor body 7.Described reactor body 7 is a rectangular shape.
Sewage mixes with the reactor body 7 inner bio-carriers of placing 3 from water inlet pipe 1 water inlet of reactor body 7 one sides.Pressurized air connects by compressed air inlet pipe 4 and enters the boring aeration pipe 5 that is arranged at the bottom of the case, to the sewage inflation, gives the membranaceous biological group oxygen supply on the bio-carrier 3.The tubular graticule mesh 6 of reactor body 7 opposite sides in reaction tank, makes the water after the processing be collected to water tank 8 by tubular graticule mesh 6 on bio-carrier 3 retaining, and the rising pipe 2 by water tank one side flows out then.The utility model has following characteristics and benefit with respect to prior art: be applied to (a) that microbial film mainly anchors on the filler in the aerobe reactor of sewage disposal, sludge retention time and hydraulic detention time are irrelevant, long, the microorganism very littler than rate of rise can grow on filler, thereby strengthen the denitrogenation ability growth such as nitrifier, nitrococcus generation time.Denitrification process is divided into two stages of nitrification and denitrification, is finished by nitrifier and denitrifying bacteria respectively.The aerobe reactor that is applied to sewage disposal can be realized the spatially relatively independent growth of nitrifier and denitrifying bacteria, thereby has optimized the growth conditions of two kinds of floras.The clearance that experiment showed, this reactor total nitrogen is 80%, and hydraulic detention time can reach 4-5 hour.When (b) handling high loading sewage, the stable performance under high-load condition of this reactor process, but multi-cascade or is used with traditional activated sludge process at interval with disposing of sewage.Effect stability when handling refinery and ethylene production waste water, the chemical oxygen demand (COD) 1500mg/l of water inlet, the chemical oxygen demand (COD) of treated its water outlet is reduced to 40mg/l, and pollutants removal rate reaches 97%.(c) characteristics tubular graticule mesh 6 can effectively prevent sludge blockage.In order to prevent that filler from losing with handling current, the water outlet place of this reactor aeration tank is provided with tubular graticule mesh 6, uses boring stainless steel plate material, smooth in appearance, and corrosion-resistant, the flow area is big.The common fillers flase floor of reactor aeration tank, the situation that the agglomerate suspended sludge in the reactor aeration tank often blocks the water outlet flase floor.Boring stainless steel plate tubbiness grid smooth in appearance, adsorptivity is little, and the flow area is big, and the gap is strengthened guaranteeing to hold back under the prerequisite of filler as far as possible, is difficult for being adhered to by suspended matter, and floating stuffing is not easy to stop, and is not easy to occur the sludge blockage phenomenon.Avoid the normal operation of this problems affect entire sewage treatment system.(d) reactor body 7 is rectangle, and is simple in structure.The length-depth ratio of reactor body 7 helps filler when being 0.5 left and right sides mobile fully, perhaps solves the problem at dead angle in the pond by the pump circulation of flow deflector, and gas-water ratio is dropped to about 4: 1.The special resistance of the simple structure of reactor body 7 and waterpower is little, cuts down the consumption of energy, and has further improved the economic benefit of this reactor.(e) the utility model adopts the perforated pipe aerating regulation system, and the aperture is downward, and is simple in structure, and material is obtained easily, and processing and installation are easy, and gas distribution is even, and pore is difficult for precipitated sludge blockage.
