Abstract
The invention discloses an integrated Orbal oxidation ditch, which belongs to the technical field of water treatment and comprises a plurality of elliptical oxidation ditches, wherein two or more than two circular areas are arranged at the central island position of each oxidation ditch, the two circular areas are tangent to the inner wall of the adjacent oxidation ditch or share the wall, and process water of each area is communicated.
Description
Technical field
The present invention relates to a kind of Bauer difficult to understand (Orbal) oxidation ditch, belong to water-treatment technology field, refer in particular to a kind ofly will precipitate, modified version Ao Baoer (Orbal) oxidation ditch that oxidation ditch process is integrated in one.
Background technology
Bauer (Orbal) oxidation ditch difficult to understand is circular or oval-shaped oxidation ditch, divide two ditches, three ditches, various ditches such as four ditches, Center Island is established in the centre, the Center Island both sides, the bottom is concrete, middle walls is the integrated unitized construction that is separated to form with reinforcing bar collar tie beam and brick wall, during design Ao Baoer (Orbal) oxidation ditch, usually these ditches are pressed anaerobism, anoxic, aerobic zone distributes, the most of design of the settling tank that sets in the technology is in the oxidation ditch outside, make the bulk treatment device not compact, reduce floor space simultaneously in order to reduce investment outlay, occurred the treatment unit of settling tank design in oxidation ditch Center Island position, " a kind of waste disposal plant of the A2/O of employing oxidation ditch process " disclosed as Chinese patent CN03223656.5, by anaerobic pond, anoxic pond, oxidation ditch, settling tank is formed, settling tank and oxidation ditch close and are concentric bilayer wall pond cylindraceous body, oxidation ditch is in the outside, settling tank is in the inboard, anoxic pond is outside oxidation ditch, near anoxic pond outer be anaerobic pond, though the vacant lot between the Chi Yuchi has been saved in this design, shared body of wall saves the pipe connecting between the body of pond, but the round settling tank that is positioned at the Center Island place is an independent settling tank, only guaranteed settling tank volume enough could be realized the precipitate and separate purpose greatly, settling tank will account for the 10-20% of total oxidation ditch cost, from whole facility, still exist floor space huge, the defective that cost is too high, handiness on using in addition is not enough, if run into the settling tank maintenance, whole device will be stopped work.
If the Center Island position is set to an independent anaerobic zone, or is designed to an independent oxidation ditch, from design angle, no matter these two kinds of forms still are being that layout is provided with all not quite rationally on the floor space.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, provide a kind of layout more to become reasonable, floor space is little, cost drops into low, integral Pall easy to maintenance (Orbal) oxidation ditch, innovative point is that the Center Island position designs the circle more than two at least, two circle and the adjacent tangent or shared wall of oxidation ditch inwall, under identical hydraulic detention time, this equipment has been saved construction investment, reduced the floor space of oxidation ditch and settling tank, equipment is more reasonable, one-piece construction more can co-ordination, further reduce the delivery cost by shared wall, reduce floor space, specifically implement like this: integral Pall (Orbal) oxidation ditch, comprise oval-shaped several oxidation ditches, the Center Island position that it is characterized in that oxidation ditch is provided with two or more circle, wherein two circle and the adjacent tangent or shared wall of oxidation ditch inwall, and each is distinguished process water and is communicated with.
Two or more circle of this equipment can be distributed in the optional position in the Center Island, distributing preferably is to have two circle to be positioned at Center Island two, and with the tangent or shared wall of adjacent oxidation ditch inwall, the best is to share the semicircle wall, save most cost like this, layout is also more reasonable.
This equipment can all be designed to the settling region in the circle of Center Island position, also can be designed as at least two settling regions, remaining circle is anaerobic zone or inside/outside recirculating zone, according to the settling region needs principle of the longer residence time, the circle number of settling region is greater than the number of anaerobic zone or inside/outside recirculating zone.Have at least this equipment of two settling regions can adapt to different waterpower processing requirements like this, particularly can use in turn, when device fails, can a maintenance, a use, and do not hinder the operation of total system.If the inside/outside recirculating zone is set, internal reflux district or external reflux district can be set separately, also can two all establish, water in the septal fossula enters the settling region by internal reflux district part, the part internal reflux prolongs the residence time of sewage in oxidation ditch to outer fissure, the external reflux district is communicated with the settling region, part mud in the settling region can be back to the active sludge content that increases oxidation ditch in the outer fissure by the external reflux district, improves and removes nitrogen removal efficiency.
The present invention is in order to have made full use of the vacant volume of Center Island, avoid the sludge bulking of oxidation ditch, make the layout of itself and other facility harmonious, floor space significantly reduces, improve the handiness that entire equipment is used, make shared body of wall more, save cost greatly, reduce cost of investment, method is that anaerobic zone or inside/outside recirculating zone are laid in the mezzanine space of circular settling region and the formation of oxidation ditch body of wall preferably.
The present invention has made full use of the position, middle island of traditional Ao Baoer (Orbal) oxidation ditch, settling region or settling region and anaerobic zone, inside/outside recirculating zone are introduced, made oxidation ditch integral device layout more coordinate rationally the space availability ratio height, floor space is littler, capital cost is lower, and the settling region more than two particularly is set, and has increased the handiness that equipment uses, adapt to the variation requirement of the water yield, water quality, technological adaptability is strong, integrates aesthetic property, practicality, and is easy to use.

Fig. 2 is the structural representation of the embodiment of the invention 2.
Fig. 3 is the structural representation of the embodiment of the invention 3.
Embodiment
Embodiment 1, integral Pall (Orbal) oxidation ditch, comprise oval-shaped several oxidation ditches 1, the Center Island position of oxidation ditch is provided with two circular settling regions 2, two circular settling regions 2 are tangent with adjacent oxidation ditch inwall, circular settling region 2 is changed to anaerobic zone 3 with the mezzanine space that oxidation ditch inwall body of wall forms, and anaerobic zone 3, each ditch 1 of oxidation ditch, settling region 2 process waters are communicated with.
Aforesaid device, anaerobic zone of setting up or inside/outside recirculating zone, do not increase investment, just utilize the position between Center Island position or the settling region, make the removal effect of total nitrogen more obvious, do not require the total nitrogen emission request for some, owing to do not increasing former Bauer difficult to understand (Orbal) oxidation ditch construction investment, increased under the situation of pure anaerobic system, made BOD, the COD leading indicator is further removed, to requiring total nitrogen discharged place, do not need to increase extra investment, reducing investment outlay to increase a technology, reaches economic aim, and saves floor space greatly, circular bay wall wall and septal fossula inner arc road common wall, saved cost again greatly, with a settling tank, more saved floor space and layout is more reasonable than the centre.
