A kind of sequencing batch biofilm reactor that contains above-mentioned floating stuffing fast filming device referring to Fig. 5, Fig. 6, comprises biological reaction tank, the long L=25m in SBR pond; Wide B=16m; Dark H=5m, at 3.20m at the bottom of the pond, the body abutment wall 1.35m place fixed lateral wireline 13 apart from the pond, the pond body is fixed in through expansion bolt in the two ends of wireline.The cross direction along the pond, fixing respectively other 10 wireline of 1.33m at interval.In 11 transverse steel wire ropes, transverse steel wire rope 13,17,18,19,21,22,23 two ends are directly fixed on the pond body, and the material specification of each parts is referring to table 2.
At 3.20m at the bottom of the pond, the fixing 24 vertical wireline in wall 6.25m place apart from the side, pond, the length direction along the pond, 6.00m fixes other 2 vertical wireline 25,26 at interval.
Place, 6 point of crossing in that wireline 24 and 16,20,25 and 16,20,26 and 16,20 forms sets up 6 columns.Wireline 16,20,24,25,26 shortens horizontal span through being fixed in column, to be reduced to the overweight vertical deformation that transverse steel wire is caused of film device.
Strain and set up 2 root posts in the aqua region straining hydrophone, length direction is connected with steelframe along the pond between 2 root posts and between column and the body of wall.One section of wireline 14,15 is fixed in body of wall, and the other end is fixed on the steelframe between two columns.
16 floating stuffing fast filming devices of series connection on the transverse steel wire rope 13,16,17,18,19,20,21,22,23; And 13 the floating stuffing fast filming devices of on wireline 14,15, connecting; Interval 0.5m between the floating stuffing fast filming device, and each floating stuffing fast filming device is in respectively in each the aeration plate gap in the reaction tank.170 floating stuffing fast filming devices are arranged in whole pond altogether.
Because the filler frame quality of hanging behind the film significantly increases, and will cause 25 vertical deformations, be unfavorable for the stable of filler frame, so should evenly arrange column according to the size of biological reaction tank, column adopts the carbon steel material through the epoxy resin rotproofing; 25 the arranged beneath and the wireline of 25 square crossings play the support film deposition system simultaneously.
Floating stuffing fast filming device is arranged in each aeration plate gap (referring to Fig. 3; 1 is 29,30 for floating stuffing fast filming device among the figure, and 31,32 is aeration plate), can effectively avoid bubble for biomembranous shearing action on the filler; Bubble promotes to hang the inter-agency waste water of film and makes circulation movement (referring to Fig. 4 simultaneously; 1 is 29,30 for floating stuffing fast filming device among the figure, and 31,32 be aeration plate), when muddy water mixed solution can play the screening effect of commute extension membrane micro during repeatedly through film deposition system with circulation; The mikrobe that promptly be prone to adhere to filler is adsorbed gradually, at the bottom of being difficult for adherent mikrobe and being settled down to the pond with circulation; The V-type splash pan can continue circulation with aeration then with the mud dispersion train that settles down to both sides, thereby the gap of avoiding falling to aeration plate causes the dead angle area sludge aging rotten.Two baffle plates that are obliquely installed that filler basket bottom is symmetrically distributed both can play the support filler; Also can play simultaneously the guiding bubble; Thereby make in the film deposition system under the whole current direction; Avoid the disturbing influence of bubble to circulation, what help mud and filler contacts absorption and settlement action.Zone between the floating stuffing fast filming device is because aeration act as oxygen-rich area, and dissolved oxygen is that power spreads to both sides with the concentration gradient, to satisfy in the filler basket on the filler microbial film to the demand of oxygen; The Gradient distribution of this oxygen concn helps the carrying out of anaerobism (anoxic) process simultaneously, so this device has the popularization exemplary role for the biological reaction tank that requires anaerobism (anoxic) reaction.
