Specific implementation mode

Below in conjunction with the attached drawing in the utility model embodiment, to the technical solution in the utility model embodiment It being clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, without It is whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creation Property labour under the premise of the every other embodiment that is obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, in conjunction with Fig. 2, the aerobic inner circulation bio-separation reactor of the utility model, including reaction vessel 1, Bucket 2, flooding tube 3, sludge pipe 4, aeration head 5, partition board 6, downflow weir 7, isolating cylinder 8 and inclined tube 9.

Reaction vessel 1 provides the space of reaction and cycle, and total mud discharging mouth 11 and effluent weir 14 are offered on wall, respectively Sludge for precipitation to be discharged and upper layer clear water.Specifically, total mud discharging mouth 11 is arranged in 1 bottom of reaction vessel.

2 inside of bucket is used as the areas Chu Chen, is first reaction zone that extraneous water inlet is passed through.Bucket 2 is arranged in reaction vessel 1 Interior, flooding tube 3 passes through reaction vessel 1 and stretches into reaction vessel 1, and sludge pipe 4 is connected to bucket 2 and extend into outside reaction vessel 1. Specifically, the flooding tube 3 includes center stabilizing feed well and horn mouth, horn mouth stretches into 2 bottom of bucket.Entire bucket 2 is similar to One complete suspended matter settling zone, using the vertical-flow precipitation method, waste water reaches 2 bottom of bucket by center stabilizing feed well, horn mouth Portion, the larger suspended matter of its own gravity and body refuse can then be fallen in bucket, it is clarified after waste water reach overflow crest of weir 7 and flow automatically Enter next reaction zone, the body refuse deposited in bucket 2 is periodically discharged through sludge pipe 4 outside reaction vessel 1.

Partition board 6 is nested between reaction vessel 1 and bucket 2 and 1 inner space of reaction vessel is divided into 12 He of race way Aeration zone 13, bucket 2 are set in race way 12, and aeration head 5 is set in aeration zone 13, and race way 12 and aeration zone 13 are distinguished It is interconnected in 6 top and bottom of partition board, bucket 2, downflow weir 7 and race way 12 are sequentially communicated.In this way, handled through bucket 2 Waste water enters in aeration zone 13, and the rate of oxygen in waste water greatly improves, and provides an aerobic microbiological life cycle well Border.Preferably, the aeration head 5 is micro-hole aerator, it is characterized in that aeration is uniform, the aeration of other forms also may be selected certainly Equipment.Specifically, aeration head 5 is installed on the middle top of reaction vessel 1, reduce the pressure of gas output, therefore also referred to as this aeration Method is Inka aeration method.Specifically, aeration head 5 is apart from 1 distance from top 1-7m of reaction vessel.

The waste water that aeration is completed recycles from top to bottom from top to bottom, again between aeration zone 13 and race way 12.It is aerobic micro- Biology is continuous to run in sufficient oxygen atmosphere, and constantly metabolism will be consumed constantly in waste water microorganism Organic matter, to achieve the effect that purification of water quality.

In order to improve settling velocity, the aerobic inner circulation bio-separation reactor of the utility model is also provided with two heavy areas, It includes isolating cylinder 8 and inclined tube 9, and isolating cylinder 8 is nested between partition board 6 and reaction vessel 1 and top and reaction vessel 1 seal, The tube settling district 15 of bottom connection aeration zone 13 is formed between isolating cylinder 8 and reaction vessel 1, inclined tube 9 is set to tube settling In area 15, effluent weir 14 is set to 9 top of inclined tube.By continuous metabolic response, it is constantly dead to have a microorganism, dead Microbic mass can enter tube settling district with the direction of flow, be divided into using inclined parallel pipe or parallelpiped a series of shallow The layer beds of precipitation, processed and sedimentation heavy mud are mutually moved and are detached in each precipitation shallow-layer.Tube settling shortens particle Settling height effectively raises treatment effeciency so as to shorten the sedimentation time, and the body refuse of precipitation returns to cyclic aeration area 13, Active sludge continues to run, and dead microorganism cenobium is then deposited in 1 bottom of reaction vessel, passes through total mud discharging mouth 11 Discharge.Specifically, reaction vessel 1 includes cylindrical base 16, tubular top 17 and interconnecting piece 18,17 diameters are more than cylinder at the top of tubular Shape bottom 16,18 size of interconnecting piece is gradually reduced from top to bottom and upper and lower ends are separately connected tubular top 17 and cylindrical base 16,8 face interconnecting piece 18 of isolating cylinder setting, effluent weir 14 is set on 17 at the top of tubular.

Finally, the areas Chu Chen and tube settling district equal 15 will produce the sludge of deposition, and the areas Chu Chen sludge is mainly shown as anaerobism Mud, the sludge that tube settling district generates are mainly shown as that aerobic mud, two kinds of sludge are separated discharge reaction vessel 1, do not interfere with each other, Total mud discharging mouth 11 has gate valve control, is conveniently operated, uses.

Under the effect of continuous circular response, final waste water is purified, and is flowed out by the downflow weir 7 of tube settling district 15, The sludge of generation is individually discharged through total mud discharging mouth 11, then joint disposal.

The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all Within the spirit and principles of the utility model, it is new to should be included in this practicality for any modification, equivalent replacement, improvement and so on Within the protection domain of type.
