But during existing Technology is more directly to regulate pH, remove residue roughly, or fine filtering can not turn again to the water charging system of power plant the most again after bio-oxidation pond, it is unfavorable for the protection of environmental conservation and water resource.
[utility model content]
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that the processing means of a kind of waste water of heat-engine plant, enables the waste water after process to turn again to the water charging system of power plant, reduces the discharge of sewage, improves resource reusing.
In order to achieve the above object, this utility model includes being connected regulating reservoir with grid, and regulating reservoir connects oil skimming pond, and oil skimming pond connects contact-oxidation pool, and contact-oxidation pool connects sedimentation tank, and sedimentation tank connects fiber bundle filter, and fiber bundle filter connects sterilization pool.
Described contact-oxidation pool includes being placed in the perforation water-locator that bottom is connected with oil skimming pond, is placed in the film reaction district above perforation water-locator, and perforation water-locator and film reaction interval are provided with Aeration tank, and film reaction is provided with filler in district.
Described Aeration tank connects Aeration fan, is provided with aeration effusion meter between Aeration tank and Aeration fan.
Described grid connects sump, and sump connects regulating reservoir.
Described sump connects regulating reservoir by elevator pump.
Described sterilization pool offers feeding opening.
Described sedimentation tank connects sludge concentration tank, and sludge concentration tank connects mechanical dehydration pond, and the waste liquid outlet in mechanical dehydration pond connects regulating reservoir.
Described mechanical dehydration pond uses belt squeezing pressure filter.
Described fiber bundle filter uses molecule polypropylene fibre bundle as filtering material.
Described sedimentation tank is vertical sedimentation basin.
Compared with prior art, this utility model by after waste water filtering residue after microbe films osculation oxygenation method organics removal, nitrogen, phosphorus, fine residue is removed further through high-efficiency fiber bundle filter through sedimentation tank, reuse standard is can reach after sterilized, waste water after this device processes can turn again to the water charging system of power plant, reduce the discharge of sewage, improve resource reusing rate.
Further, the waste liquid outlet in this utility model mechanical dehydration pond connects regulating reservoir, it is possible to recycling waste liquid, saves resource.
Further, fiber bundle filter of the present utility model uses molecule polypropylene fibre bundle as filtering material, the most several up to tens microns microns of its filtrate diameter, reach micron order, relative to particulate filter, it is big that fiber bundle media has specific surface area, and the advantages such as filtration resistance is little solve the filtering accuracy of particulate filter by problems such as particle diameter of filter medium are limited.
Further, vertical sedimentation basin selected by sedimentation tank of the present utility model, and spoil disposal is convenient, and floor space is less.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is described further.
See Fig. 1, this utility model includes being connected regulating reservoir 4 with grid 1, sump 2 it is provided with between grid 1 and regulating reservoir 4, sump 2 connects regulating reservoir 4 by elevator pump 3, regulating reservoir 4 connects oil skimming pond 5, oil skimming pond 5 connects contact-oxidation pool 6, contact-oxidation pool 6 connects sedimentation tank 13, sedimentation tank 13 connects fiber bundle filter 14 and sludge concentration tank 17, sludge concentration tank 17 connects mechanical dehydration pond 18, the waste liquid outlet in mechanical dehydration pond 18 connects regulating reservoir 4, and fiber bundle filter 14 connects sterilization pool 16, and sterilization pool 16 offers feeding opening 15.
Contact-oxidation pool 6 includes being placed in the perforation water-locator 7 that bottom is connected with oil skimming pond 5, it is placed in the film reaction district 10 above perforation water-locator 7, it is provided with Aeration tank 8 between perforation water-locator 7 and film reaction district 10, filler 9 it is provided with in film reaction district 10, Aeration tank 8 connects Aeration fan 12, is provided with aeration effusion meter 11 between Aeration tank 8 and Aeration fan 12.
Preferably, mechanical dehydration pond 18 uses belt to squeeze pressure filter, and fiber bundle filter 14 uses molecule polypropylene fibre bundle to be vertical sedimentation basin as filtering material, sedimentation tank 13.
Method of work of the present utility model, comprises the following steps
Step one, sewage carries out pretreatment, and grid 1 is used for retaining larger particles float;
Step 2, the sewage after step one processes then enters regulating reservoir 4, and regulating reservoir 4 can improve biological treatment structures service condition, effectively regulates water quality, the water yield, pH, it is simple to subsequent treatment;
Step 3, the sewage after step 2 processes carries out oil skimming pond 5 oil removal and processes, effectively reduces the COD of biological treatment;
Step 4, the sewage after step 3 processes enters two stage treatment, carries out biological oxidation in biological contact oxidation pond, and major part Organic substance is removed in degraded, can also effectively remove phosphorus, nitrogen simultaneously;
