Description

Four-in-one sewage treatment equipment

Technical field

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

Background technology

At present, usually utilize oxidation ditch, adopt A2/O technique to process trade effluent and sanitary sewage; The devices such as wherein involved anaerobic treatment, anaerobic treatment, aerobic treatment and precipitation process are all arrange respectively.Not only floor space is large, long construction period, but also need install lift technique, aerating apparatus, mixed-liquor return equipment, sludge reflux equipment, flow pulling equipment, whipping device, scrapes 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 existed 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 treatment equipment of keeping in repair.

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

Ring-shaped splash guard is fixed with in the below of effluent weir; Extract pipe is inclined upwardly layout, and circulating tube is arranged bottom treating pond; Evacuated tube is arranged at the bottom for the treatment of pond.

Compared with the prior art, the devices such as anaerobic treatment, anaerobic treatment, aerobic treatment and precipitation process, owing to have employed technique scheme, are integrated in a set of equipment, effectively reduce floor space, shorten construction period by the present invention.In addition, due to the energy that the present invention takes full advantage of input aeration air, while completing aeration, make gas float, thus sewage and mud are fully flowed in each interval; Achieve in whole plant without rotating machinery, non-transformer access, no-movable part, without any valve.Not only thoroughly eliminate and solve maintenance and change component trouble, but also eliminate lift technique, mixed-liquor return equipment, sludge reflux equipment, flow pulling equipment, whipping device, scrape mud equipment etc., reduce to build and drop into, there is the advantages such as compact construction, energy consumption is 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, the ring-type effluent weir 27 be communicated with rising pipe 25 is fixed with in inner barrel 3; In the inner ring of this effluent weir, have the central tube 1 be communicated with water inlet pipe 7, be fixed with inclined tube assembly 2 between the outer wall of this central tube and the inner ring of effluent weir 27, the below of this inclined tube assembly is anaerobic zone 14; Have in the below of effluent weir 27 and be distributed in some water holes 4 that this inner barrel is communicated with treating pond 6 on inner barrel 3.The outer wall of inner barrel 3 is fixed with the dividing plate 13 treating pond 6 being divided into upper and lower two regions, the top of this dividing plate is aerobic zone 5; The some aeration heads 10 be communicated with airduct 24 by aeration tube 8 are had in this aerobic zone.The below of dividing plate 13 is the toroidal membranes 22 be fixed on bottom treating pond 6, has venting port 23 between this toroidal membrane and dividing plate 13, forms oxygen-starved area 20 between dividing plate 13 and toroidal membrane 22; This oxygen-starved area is communicated with aerobic zone 5 by the some return lines 12 be fixed on dividing plate 13.Have the air chamber 16 be fixed on bottom inner barrel 3 in oxygen-starved area 20, this inner barrel is communicated with oxygen-starved area 20 by the some extract pipes 18 being fixed on inner barrel 3 conical lower portion; The many stripping tubes 15 be fixed on air chamber 16 stretch into respectively in corresponding extract pipe 18 and are communicated with oxygen-starved area 20 by air chamber 16.Region between the outer wall of toroidal membrane 22 and treating pond 6 inwall is upflow channel 9, has the some other aeration head 10 be communicated with airduct 24 by endless tube 21 in this upflow channel; The wall of toroidal membrane 22 is distributed with the circulating tube 19 of some connection upflow channel 9 and oxygen-starved area 20, shore pipe 17 extends upwardly into the bottom of inner barrel 3 through air chamber 16 and is communicated with anaerobic zone 14.

Impacting in order to avoid being formed, being fixed with the water eliminator 26 of annular in the below of effluent weir 27.

In oxygen-starved area 20, form circulation for the ease of muddy water, extract pipe 18 adopts acclivitous mode to arrange; For the ease of processing muddy water, circulating tube 19 adopts the mode bottom treating pond 6 to arrange.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 is entered by water inlet pipe 7 and is advanced into anaerobic zone 14 under after central tube 1 and mixes with the mud precipitated, then by carrying power that pipe 15 provides, will being gathered in the sludge water of inner barrel 3 pyramidal portion from suction oxygen-starved area, anaerobic zone 14 20 by extract pipe 18, air is then discharged by venting port 23; Sludge water is under the effect of air-flow, gyration in oxygen-starved area 20, and enter upflow channel 9 by circulating tube 19, then aerobic zone 5 is entered, sewage enters the below of inclined tube assembly 2 after aerobic treatment under the guiding of water eliminator 26 by water hole 4, after solid-liquid separation, supernatant liquor is flowed out by rising pipe 25 by effluent weir 27, and the bottom sinking down into inner barrel 3 is then discharged by shore pipe 17.
