Waffle slab 30 arranges (as shown in Figure 3) along being perpendicular to upstream and downstream direction, and waffle slab 30 is positioned at flow guide system 20 plate downstream；Waffle slab 30 for example, 304 metal material such as grade is made, and its mesh aperture is 5～8mm to be preferred.
This utility model onsite application mode is as follows:
XCSBR cycle of operation includes: water inlet → mixing → cyclic aeration → precipitate → strain water.Whole service program can be passed through prior art, such as PLC program and carry out manual adjustment, according to influent quality and effluent quality requirement, is adjusted the operation time in each stage.Specific as follows:
Water inlet and mix stages: pending sewage is entered in biochemical reaction tank 10 by water inlet pipe 11 by water inlet, and generation mixed liquor is mixed with the mud in biochemical reaction tank 10, under abundant volatile fatty acid VFA supply, denitrifying bacterium and polyP bacteria in mud carry out denitrification and release phosphorus, ADP → ADT, the VFA of polyP bacteria absorption simultaneously become PHB (Poly-β-hydroxybutyric acid) and are stored in microbial body；After water inlet reaches certain water level, it is automatically stopped into water；
The cyclic aeration stage: after wastewater influent reaches certain water level, be automatically stopped into water；Aeration draws exposure automatically, and cyclic aeration process major function is nitrification, removes kjeldahl nitrogen and carbonisation, and PHB is carried out breeding (ADT → ADP) by polyP bacteria as substrate simultaneously.Among the present embodiment, aeration assembly 142 is positioned at bottom biochemical reaction tank 10, carrying out along with aeration, gas is by bottom up, agitation mixed liquor flows up, encounter deflector 21 tailing edge deflector face to continue to rise, until encountering overhead guard 22, under the blocking of overhead guard 22, gas and the mixed liquor direction of motion change, then flowing of flowing out from the gap between overhead guard 22 and deflector 21 and face down along deflector 21, it is returned to bottom biochemical reaction tank 10, again under the drive of aeration upwards, so, gas, mixed liquor carries out circulation movement along deflector 21, so that mixed liquor and oxygen can fully mass transfer and utilizations, substantially increase utilization rate and the Chi Rong of oxygen, promote the carrying out of microbial treatments enzymatic reaction；Meanwhile, the formation of waterpower circulation has the effect of activated sludge, promotes that activated sludge is fully dispersed becomes granule sludge, and the most each granule sludge is exactly a miniature biochemical device, promotes reaction to carry out the most thorough；
Precipitate phase: after aeration terminates, mixed liquor staticly settles, the layering of mud under water in formation；Now bulky grain mud the most fully precipitates；Upper water also has the least granule and float etc.；
Strain the water stage: after precipitation terminates, digital controlled valve automatically turns on, and water decanter 40 starts to strain water；First open arm 121, initial water outlet is vented back to biochemical reaction tank 10 water inlet, is then turned on the formal draining of outlet pipe 12；During straining water, upper water stream carries out mud granule reflocculation and waterpower current stabilization through waffle slab 30, removes oil removal and rich phosphorous sludge, is also carried out the stable of microorganism and physiology conditioning simultaneously；Specifically, current can form whirlpool through the mesh of waffle slab 30, and the little granule of colloid strengthens mutually collision in whirlpool, and mutually flocculation and gathering form bulky grain in collision process；According to stokes principle, square being directly proportional of the sedimentation velocity of granule and grain diameter, the least granule is also sedimentation downwards during becoming larger, such secondary precipitation can fully remove little granule and float, enhance mud-water separation effect, make effluent quality cleaner, the one-level A standard in GB18918 2002 urban wastewater treatment firm pollutant emission standard can be directly reached；Straining after water depth reaches certain position, digital controlled valve is automatically switched off, and stops straining water, and a cycle of operation terminates.
Among the present embodiment, described water decanter 40 enters formula pontoon decanter under being, as shown in Figure 4 and Figure 5, including the floating drum 41 arranged up and down, connecting rod 42, under enter straining tank 43, straining water pipe 44 and sleeve pipe 45 of formula, and floating drum 41, connecting rod 42, strain tank 43, strain water pipe 44 and sleeve pipe 45 is located substantially in same vertical plane；Floating drum 41 is two hollow tubular structures that the parallel interval being connected by connecting rod 42 is arranged with straining tank 43, preferably oval tubular structure, but floating drum 41 is totally enclosed type, for providing buoyancy for water decanter 40 so that it is can be suspended in water and can change with SEA LEVEL VARIATION；And the positive bottom straining tank 43 is provided with opening i.e. for the notch 431 of water inlet；Floating drum 41 and strain tank 43 level and be suspended in water, floating drum 41 upper, strain tank 43 under；Strain water pipe 44 vertically to arrange, be fixed in the underface strained in the middle part of tank 43, strain water pipe 44 and strain tank both 43 and complement each other to form class T font structure and be interconnected；Sleeve pipe 45 is vertically fixed in biochemical reaction tank 10 pool wall by reinforcing bar or embedded bracket etc., strains water pipe 44 hypomere and and can be slided up and down by facing sleeve in sleeve pipe 45 epimere by some sealing rings sealing sliding installation；Sleeve pipe 45 lower end connects with the outlet pipe 12 being in tilted layout.
During draining, first open the digital controlled valve of arm 121, the water accumulated in water decanter 40 and water decanter 40 just section water outlet are vented back to biochemical reaction tank 10 water inlet automatically；Being then turned off arm 121, open the digital controlled valve of outlet pipe 12, along with straining the carrying out of water, the upper water in biochemical reaction tank 10 enters from notch 431 and strains in tank 43, confluxes into straining water pipe 44, goes through and strains water pipe 44, sleeve pipe 45 and outlet pipe 12 and discharge；Along with water level is gradually reduced, floating drum 41 moves down with water level, drives simultaneously and strains water pipe 44 slide downward in sleeve pipe 45, so that water decanter 40 declines with water level decreasing；When draining stops, again after water inlet, along with water level is gradually increasing, floating drum 41 moves with on water level, drives simultaneously and strains water pipe 44 upward sliding in sleeve pipe 45, so that water decanter 40 rises with water level and rises.
Water decanter 40 is strained the notch 431 of tank 43 and is arranged on the underface straining tank 43, and when so intaking, scum silica frost floating on the water surface, foam etc. will not enter water decanter 40, it is to avoid the pollution to water outlet, it is also possible to save the design arranging mud guard at notch 431；Secondly, water decanter 40 employing is strained water pipe 44 and is sealed the form slided up and down, simple in construction in sleeve pipe 45, and volume is little, takes up room little, and each parts coordinate compact, smooth running, strains water speed uniform, and the water surface is steadily without fluctuating；With being slidably socketed design, floating drum 41 also can guarantee that water decanter 40 changes with SEA LEVEL VARIATION, and keep the depth of water at notch 431 to keep stable, reaches to strain the optimum efficiency of water, it is possible to discharge the upper water in biochemical reaction tank 10 accurately and do not stir the mud of bottom.
The above, only this utility model preferred embodiment, therefore the scope that this utility model is implemented can not be limited according to this, the equivalence change i.e. made according to this utility model the scope of the claims and description with modify, all should still belong in the range of this utility model contains.
