Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, heterogeneous circulation integrated sewage treating apparatus comprises: oil removal septic tank 10; Heterogeneous circulating biological pond 20, and vertical fiber cloth filter tank 30.
As depicted in figs. 1 and 2, oil removal septic tank 10 is syllogic, what have H-shaped between adjacent two sections crosses water passage 11, owing to oil ratio water is light, therefore greasy dirt can float over the upper strata of sewage, the lower end crossing water passage 11 is immersed in water layer, and therefore only water can be entered among next section of oil removal septic tank by the water passage of crossing of H-shaped. Oil removal septic tank 10 carries out oily water separation, particle precipitation and anaerobically fermenting.
In last section of oil removal septic tank 10, with the position that heterogeneous circulating biological pond 20 is connected, it is provided with cartridge type grid 12. As shown in Figure 7, cartridge type grid 12 comprises grid body 121, scrape tablet 122 and pull bar 123, scrape tablet 122 for circular, it is enclosed within the outside of cartridge type grid body 121, when the mud accumulation on cartridge type grid body 121 surface is more, affect current when passing through, pull pull bar 123 up and down so that scrape tablet 122 and move reciprocatingly on the surface of cartridge type grid body 121, scrape off the mud on the surface of cartridge type grid body 121. Oil removal septic tank 10 and heterogeneous circulating biological filter tank all have vapor pipe 13.
Sewage enters oil trap, after three grades of oil removals, enters next processing unit. This oil trap can be used as again septic tank, anaerobic degradation part COD, reduces the BOD loading of subsequent biological treatment. Oil trap regularly must drag for clearly the vegetable and animals oils on surface, according to food and drink situation, within 1-7 days, drags for once clearly, and the mud of bottom, then drew clearly once by 1 year half a year.
As shown in Figures 2 and 3, heterogeneous circulating biological pond 20 has umbrella and exposes air-lift device 21, corrugated biologic packing material layer 22, and interval shore pipe 25.
As shown in Figure 4, corrugated biologic packing material layer 22 has the filler plate 221 of multiple inclination to the internal structure of corrugated biologic packing material layer 22, filler plate 221 has spination depression, for microorganic adhesion. When sewage from upper flow through filler plate downwards time, the particulate matter of sewage inside enters in the depression of filler plate 221, the microbial decomposition wherein adhered to. The angle of filler plate and horizontal plane is 70 ��, adds the iris action to water so that particulate matter more easily deposits for bacterial degradation. In other embodiments, the angle of filler plate and horizontal plane can change in the scope of 65 �㡫75 ��.
Space is left between at the bottom of the bottom of corrugated biologic packing material layer 22 and the pond in heterogeneous circulating biological pond.

Like this, above sewage rises to below corrugated biologic packing material layer 22, umbrella expose carry out aeration time, sewage from top to bottom flow through corrugated biologic packing material layer 22, the high sewage of oxygen level is by the microbial decomposition in corrugated biologic packing material layer 22.
Boring aeration pipe 23, is arranged on the lower section of corrugated biologic packing material layer, upwards carries out aeration below corrugated biologic packing material layer. Like this so that in the water body up and down of corrugated biologic packing material layer 22, carry out aeration simultaneously, further increase the effect of aeration. As shown in Figure 5 and Figure 6, interleaved on bottom aerated conduit 23 have solarization air cap 231, and adjacent two solarization air caps 231 are 45 �� with the angle of the heavy vertical line of pipeline, to strengthen aeration effect further.
Corrugated biologic packing material and above-mentioned aeration mode, have the following advantages:
Umbrella exposes air-lift device aerating pipelines and stretches into oxygen supply bottom filler, increases the utilization ratio of oxygen, and passes through the many to cutting of filler, aqueous phase is acutely mixed, it is to increase aeration effect with gas phase;
Exposed the gas stripping of air-lift device aerating pipelines by umbrella, by the sewage lifting at the bottom of pond to, in air, making sewage and air mixed, form two aerations, increase aeration rate;
Air-lift device gas stripping is exposed by umbrella, sewage rises in air by bottom, then fall and return in Sewage treatment systems, this process carries out repeatedly, form an internal circulation system, add the residence time of sewage in aerating system, the COD in the abundant degradation of sewage of microorganism, it is to increase wastewater treatment efficiency.
Be arranged in below packing layer by boring aeration pipe, make air be distributed in pond body, in air-lift process, many to cutting by filler, make aqueous phase acutely mix with gas phase, increase oxygen utilization rate, it is to increase aeration effect.
Heterogeneous circulating biological pond 20 also has air lift mud discharging device 25, mud bottom heterogeneous circulating biological pond is extracted and returns and drain in oil removal septic tank 10, carry out anaerobic digestion again, with the organic content reduced further in mud, reduce the growing amount of mud on the one hand, make organic content in the mud of final discharge significantly decline on the other hand so that when mud is carried out landfill disposal by the later stage, the gas production rate of mud reduces, and mud is more stable.
Umbrella exposes air-lift device and air lift mud discharging device 25 shares a gas blower as power resources.
The lower end of air lift mud discharging device 25 extend in collection bucket 27, and the height of collection bucket is lower than at the bottom of the pond below corrugated biologic packing material layer, so that mud is built up.
The main purpose in heterogeneous circulating biological pond 20 is degradation COD, BOD, and denitrogenation dephosphorizing.
