Detailed description of the invention
This utility model embodiment will be described in further detail below.
A of the present utility model2/ O-MBR integrated sewage treating apparatus, its preferably detailed description of the invention be:
Including the anaerobic pond set gradually from front to back, anoxic pond, Aerobic Pond, described anaerobic pond, anoxic pond, Aerobic Pond is located in an overall pond and is separated by dividing plate, dividing plate is identical with the height in pond, one jiao, the bottom of the dividing plate of described anaerobic pond and anoxic pond arranges apopore, one jiao of the dividing plate top of described anoxic pond and Aerobic Pond arranges spout hole, described anaerobic pond and anoxic pond are provided with water inlet pipe, aerator and hollow-fibre membrane it is provided with in described Aerobic Pond, described hollow-fibre membrane is provided with outlet pipe, it is provided with return duct between described Aerobic Pond and anaerobic pond, described water inlet pipe is connected to intake pump, described outlet pipe is connected to out water pump and backwashing pump, described return duct is provided with reflux pump and mud discharging mouth, described aerator is connected to blower fan.
Described anaerobic pond, anoxic pond, Aerobic Pond volume ratio be 1:2:4.
The return duct interface of described Aerobic Pond is away from described aerator.
Described water outlet delivery side of pump water pipe is provided with ultraviolet sterilizer.
Described water outlet delivery side of pump water pipe is connected respectively with cleaning fluid tank and product water tank, and the import water pipe of described backwashing pump is connected respectively with cleaning fluid tank and product water tank.
Described go out to be respectively equipped with electromagnetic valve on the import water pipe of water pump and outlet water pipe and on the import water pipe of described backwashing pump and saliva pipe.
Described aerator includes the boring aeration pipe being located at bottom Aerobic Pond and the intermission aeration device being arranged on hollow-fibre membrane frame lower end.
Specific embodiment:
As it is shown in figure 1, whole device is by PLC control, when in reactor, liquid level drops to middle liquid level, intake pump starts, until stopping water inlet when liquid level rises to high liquid level.The flow of anaerobic pond and anoxic pond is entered by the valve regulated on inlet pipeline.
Anaerobic pond and anoxic pond are provided with blender, run continuously and make muddy water in pond be sufficiently mixed.Entering anaerobic pond sewage carry out aminating reaction together with the mixed liquor refluxed from Aerobic Pond in pond and release phosphorus effect, current carry out denitrification by bottom cavitation entrance anoxic pond subsequently, and the former water being partially into anoxic pond provides carbon source.Then current overflow entrance Aerobic Pond carries out nitration reaction, inhales phosphorus effect and organic matter degradation.
Film silk water-out manners is pumping, and going out water pump has PLC control, and can frequency modulation.When in reactor, liquid level goes out starting mode of pump when rising to middle liquid level, now V01 electromagnetic valve is opened, V02 closed electromagnetic valve.Go out water pump to stop when liquid level drops to low liquid level.
Whole device only has a set of return-flow system, by reflux pump by mixed-liquor return in Aerobic Pond to anaerobic pond, it is ensured that the sludge concentration of anaerobic pond and anoxic pond, nitrification liquid returns to anoxic pond simultaneously and carries out denitrification denitrogenation.Control of reflux ratio is at 100%-400%.The Aerobic Pond internal reflux mouth of pipe should away from Mo Si intermission aeration district, it is to avoid backflow dissolved oxygen is too high.
Go out water pump intermittent duty, open 9min and stop 1min, alleviate the pollution of film silk.Water outlet enters after ultraviolet sterilizer is sterilized cleans medicine-chest or produces water tank, is finally expelled directly out.
When PLC receive pressure transducer reach-30kPa time, stop water pump, open and clean pump and film silk is carried out medicine wash.Now electromagnetic valve V01 closes, and V02 opens.According to the cleaning procedure set, opens solenoid valve V03 and V04 is carried out operation.Cleaning is cleaned medicine-chest before starting and is prepared certain density medicament.
During plant running, Aerobic Pond dissolved oxygen should be controlled under about 1.0mg/L, low DO condition, realize denitrification, reduce oxygen content in mixed-liquor return liquid simultaneously.The hydraulic detention time of whole device controls at 6-10h, it is ensured that the time of contact of pollutant and mud.
The utility model has the advantage of: integrated apparatus segmental influent can organic loading in homogeneous reactor effectively, provide available organic carbon source for denitrifying bacteria in anoxic pond simultaneously, efficiently solve denitrifying carbon source deficiency.By tradition A in device2/ O internal reflux and sludge reflux merge, and use a set of mixed-liquor return system that mud in Aerobic Pond and nitrification liquid are back to anaerobic pond, not only ensure that the sludge quantity of anaerobic pond and anoxic pond but also can carry out denitrification.A set of return-flow system has been effectively saved energy consumption, reduces operating cost.Integrated apparatus outlet pipeline and film silk detergent line merge, and save construction cost, and film frame has only to an outlet simultaneously.Integrated apparatus floor space is little, and surplus sludge volume is few, capacity of resisting impact load is strong, has good Nitrogen/Phosphorus Removal, it is achieved Automatic Control etc..In addition integrated apparatus conveniently moving, have only to after transporting to scene to connect electricity just can startup optimization, be especially suitable for and pollute the sewage disposal of scattered villages and small towns.
This utility model is intake by front end, with this through anaerobic pond, anoxic pond, Aerobic Pond, eventually passes hollow-fibre membrane suction water outlet in Aerobic Pond.Wherein anaerobic pond, anoxic pond and Aerobic Pond are separated by dividing plate, and dividing plate is identical with pond height, and wherein bottom the dividing plate of anaerobic pond and anoxic pond, one jiao of one jiao of dividing plate top arranging apopore, anoxic pond and Aerobic Pond arranges spout hole.Anaerobic pond, anoxic pond, Aerobic Pond volume ratio be 1:2:4；
Water inlet system connects anaerobic pond and anoxic pond respectively, it is achieved segmental influent, it is achieved being uniformly distributed of organic loading in reactor, can improve the denitrification efficiency of anoxic pond simultaneously；
Return-flow system uses mixed-liquor return, and by reflux pump by Aerobic Pond mixed-liquor return to anaerobic pond, control of reflux ratio is at 100%-400%.Wherein Aerobic Pond refluxing opening is away from Mo Si intermission aeration district, it is to avoid in mixed liquor, dissolved oxygen is higher impacts anaerobic pond；
Outlet conduit and film silk clean pipeline and merge, by solenoid operated switching water discharging and the state of cleaning, to save pipeline.Namely, when going out starting mode of pump water outlet, go out water solenoid valve accordingly and open solenoid purge valve and then close；When cleaning pump startup and cleaning film silk, corresponding solenoid purge valve is opened water solenoid valve and is then closed.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
