Description

Four-in-one sewage disposal device

Technical field

The present invention relates to a kind of environmental protection equipment, relate in particular to a kind of equipment of processing trade effluent, sanitary sewage.

Background technology

At present, conventionally utilize oxidation ditch, adopt A2/O technique to process trade effluent and sanitary sewage; Wherein the device such as related anaerobic treatment, anaerobic treatment, aerobic treatment and precipitation process is all to arrange respectively.Not only floor space is large, long construction period, but also needs lift technique, aerating apparatus, mixed-liquor return equipment, sludge reflux equipment, flow pulling equipment, whipping device to be installed, to be scraped mud equipment etc., build have high input, energy consumption and failure rate is high, maintenance trouble.

Summary of the invention

In order to overcome the defect existing in prior art, the present invention aims to provide a kind of compact construction, it is little to invest, energy consumption is low, be convenient to the four-in-one sewage disposal device of maintenance.

To achieve these goals, the present invention by the following technical solutions: its four-in-one sewage disposal device, comprises the inner barrel being fixed in treating pond; In funnelform inner barrel, have the ring-type effluent weir being communicated with rising pipe, in the interior ring of this effluent weir, have the central tube being communicated with water inlet pipe, have inclined tube assembly between this central tube and effluent weir, there are the some water holes that are distributed on inner barrel the below of effluent weir; On the outer wall of inner barrel, be fixed with dividing plate, the below of this dividing plate is the toroidal membrane that is fixed on treating pond bottom, between this toroidal membrane and dividing plate, has venting port, has some return lines that protrude upward through dividing plate in this toroidal membrane; In toroidal membrane, have the air chamber being communicated with airduct, the below of dividing plate has and is fixed on inner barrel bottom by the extract pipe being communicated with inside and outside it, in each extract pipe, has the stripping tube being communicated with air chamber; On toroidal membrane, be distributed with some by the circulating tube being communicated with inside and outside it; Between toroidal membrane and treating pond inwall and be distributed with some aeration heads above dividing plate, shore pipe is arranged at the bottom of inner barrel.

Below effluent weir, be fixed with annular water eliminator; The extract pipe layout that is inclined upwardly, circulating tube is arranged near treating pond bottom; Evacuated tube is arranged at the bottom for the treatment of pond.

Compared with the prior art, the present invention, owing to having adopted technique scheme, is integrated in the devices such as anaerobic treatment, anaerobic treatment, aerobic treatment and precipitation process in a set of equipment, has effectively reduced floor space, has shortened construction period.In addition, the energy because the present invention takes full advantage of input aeration air makes gas floating, thereby makes sewage and mud each interval abundant flowing when completing aeration; Realized in whole plant without rotating machinery, non-transformer access, no-movable part, without any valve.Not only thoroughly eliminate and solved maintenance and changed component trouble, but also saved lift technique, mixed-liquor return equipment, sludge reflux equipment, flow pulling equipment, whipping device, scraped mud equipment etc., reduced and build to have dropped into, the advantage such as have that compact construction, energy consumption are little, failure rate is low, working cost are few.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:

As shown in Figure 1: funnelform inner barrel 3 is fixed in treating pond 6, in inner barrel 3, be fixed with the ring-type effluent weir 27 being communicated with rising pipe 25; In the inner ring of this effluent weir, have the central tube 1 being communicated with water inlet pipe 7, between the outer wall of this central tube and the inner ring of effluent weir 27, be fixed with inclined tube assembly 2, the below of this inclined tube assembly is anaerobic zone 14; Below effluent weir 27, have and be distributed in the some water holes 4 that on inner barrel 3, this inner barrel are communicated with treating pond 6.On the outer wall of inner barrel 3, be fixed with the dividing plate 13 that treating pond 6 is divided into upper and lower two regions, the top of this dividing plate is aerobic zone 5; In this aerobic zone, there are the some aeration heads 10 that are communicated with airduct 24 by aeration tube 8.The below of dividing plate 13 is the toroidal membranes 22 that are fixed on treating pond 6 bottoms, between this toroidal membrane and dividing plate 13, has venting port 23, between dividing plate 13 and toroidal membrane 22, forms oxygen-starved area 20; The some return lines 12 that are fixed on dividing plate 13 are communicated with this oxygen-starved area with aerobic zone 5.In oxygen-starved area 20, have the air chamber 16 that is fixed on inner barrel 3 bottoms, the some extract pipes 18 that are fixed on inner barrel 3 conical lower portion are communicated with this inner barrel with oxygen-starved area 20; Many stripping tubes 15 that are fixed on air chamber 16 stretch into respectively in corresponding extract pipe 18 and air chamber 16 are communicated with oxygen-starved area 20.Region between the outer wall of toroidal membrane 22 and treating pond 6 inwalls is upflow channel 9, has the some other aeration head 10 being communicated with airduct 24 by endless tube 21 in this upflow channel; The circulating tube 19 that is distributed with some connection upflow channel 9 and oxygen-starved area 20 on the wall of toroidal membrane 22, shore pipe 17 upwards stretches into the bottom of inner barrel 3 and is communicated with anaerobic zone 14 through air chamber 16.

For fear of forming, impact, below effluent weir 27, be fixed with annular water eliminator 26.

For the ease of muddy water in oxygen-starved area 20 interior formation circulation, extract pipe 18 adopts acclivitous mode to arrange; For the ease of muddy water is processed, circulating tube 19 adopts near the mode for the treatment of pond 6 bottoms to be arranged.For the ease of maintenance and cleaning, evacuated tube 11 is arranged at the bottom for the treatment of pond 6.

Principle of work: sewage enters central tube 1 by water inlet pipe 7 and is advanced into anaerobic zone 14 under rear and mixes with the mud of precipitation, then by carry pipe 15 power that provide, by extract pipe 18 by the sludge water that is gathered in inner barrel 3 centrums parts from anaerobic zone 14 suction oxygen-starved areas 20, air is discharged by venting port 23; Sludge water is under the effect of air-flow, the 20 interior gyrations in oxygen-starved area, and enter upflow channel 9 by circulating tube 19, then enter aerobic zone 5, sewage after aerobic treatment, by water hole 4, under the guiding of water eliminator 26, enter inclined tube assembly 2 below, after solid-liquid separation, supernatant liquor is flowed out by rising pipe 25 by effluent weir 27, and the bottom that sinks down into inner barrel 3 is discharged by shore pipe 17.
