In another embodiment, in described sludge sump 5, hard-wired air-blast device 52 also can be mounted in an air-blast device of this kind of sewage disposal device outside that facilitates sludge sump cleaning, only need to offer an air inlet port at sludge sump pool wall or top simultaneously.
In order to further illustrate the constitutional features of a kind of sewage disposal device that facilitates sludge sump cleaning of the utility model, now by reference to the accompanying drawings 4, concrete this sewage disposal device of application technical process illustrate, consult accompanying drawing 4, as seen from the figure, this sewage treatment process comprises following process:
(1) in above-mentioned treatment process, sanitary sewage is removed in sewage after bulk suspended substance solid by coarse rack, fine fack, and flows into equalizing tank after the sewage from catering business of air supporting oil removal processing mixes;
(2) sewage carries out homogeneous in equalizing tank, all amount is processed;
(3) by promoting water pump, sewage in equalizing tank is sent in MBBR integration apparatus, carried out biochemical treatment, and through contact sterilizing qualified discharge;
(4) excess sludge producing in biological process enters in the concentrated storage of mud pond and stores, regularly outward transport, and supernatant liquor is back to equalizing tank.
Wherein, air supporting grease trap has increased slag on traditional oil trap basis, water separates and deslagging function, air supporting function, automatic wiping function.Having improved the separation efficiency of grease, solid dirt, be conducive to the collection and use of oil slick, solid dirt, is the product innovation of traditional oil trap upgrading.
Oil removal by air bubbling process comprises that Bubble formation, bubble and greasy dirt and solid particulate adhere to rising, oil-scraping device and the step composition such as separate.Its principle is that bubble generator makes to produce in water a large amount of micro bubbles, thereby forms water, bubble and greasy dirt solid particulate three-phase mixture.Under the acting in conjunction of the many kinds of force such as interfacial tension, air supporting rising buoyancy and hydrostaticpressure be poor, after impelling micro bubble to stick on removed greasy dirt and solid particulate, float to the water surface because sticky and volume density are less than water, thereby make greasy dirt in water be separated removal with solid particulate by automatic wiping device.
Wherein, grid is installed in frame trough.Grid is mainly used to tackle the agglomerate floater in sewage, processes load to ensure the normal operation of subsequent disposal structures and effectively to alleviate, for the long-term normal operation of system is given security.
Wherein, the function of equalizing tank is: because the water quality from each period, the water yield are all different, general peak flow is 2～8 times of average treatment amount, therefore for treatment system is moved continuously and stably, and regulating pondage and homogenizing water quality simultaneously.
The built-in submersible sewage pump of equalizing tank and backflow measure, to ensure that certain rated flow is promoted to subsequent biological treatment system, reduce the impact load of the water yield to system.For ensureing in equalizing tank not deposit dirt, establish perforated pipe aerating regulation stirring system simultaneously, realize anoxic also as denitration pond in advance.
Integrated MBBR reactor explanation:
Divide pre-nitrification tank, anaerobic pond, anoxic pond, Aerobic Pond, also optionally have sterilization pool, equipment room.
The major function of anaerobic pond is to coordinate dephosphorization with Aerobic Pond.Biological phosphate-eliminating be polyP bacteria in sewage under anaerobic, be subject to constraining and discharge the phosphoric acid salt in body, generate energy is in order to absorb fast degradation organism, and is converted into poly-β hydroxybutyric acid (PHB) and stores.The PHB storing in body that just degrades in the time that these polyP bacterias enter Aerobic Pond, generate energy, for the synthetic of cell with inhale phosphorus, absorbs phosphorus in sewage and forms the phosphorus containing sludge of high density, discharges system, thereby reach the object of dephosphorization with excess sludge.
The major function of anoxic pond is denitrification denitrogenation.Denitrifying bacteria under extremely low or anaerobic conditions, can utilize nitrate at dissolved oxygen concentration in nitrogen as electron acceptor(EA) oxidation of organic compounds, the nitrogen in nitrate is reduced into nitrogen (N 2), thereby complete the denitrification process of sewage.In pond, establish perforated pipe intermittent aeration and realize anoxic.
The major function of Aerobic Pond is oxidation organic matter and nitrated ammonia nitrogen.Microorganism in active sludge, under the condition of aerobic, for the synthesis of new cell, carries out katabolism by another part organism to obtain the synthetic required energy of cell by a part of organism in sewage, and its final product is CO 2and H 2the stable materials such as O.When organism is oxidized, the organonitrogen in sewage is also oxidized to ammonia nitrogen, in the situation that dissolved oxygen abundance, mud are grown age, is further oxidized to nitrite and nitrate.
Sewage flows into tube settler after biochemical treatment, realizes mud-water separation.In pond, sludge reflux system is installed simultaneously, the active sludge in pond is drained into integration apparatus anaerobic zone by return sludge pump part.Excess sludge regularly enters sludge sump.
After regularly outward transport of mud, further carry out sludge sump cleaning, now close sewage import, the water in clean water basin can be sent into sludge sump, open air-blast device, this air-blast device can automatic rotation, to the place's air blast of pool wall dead angle, thus thorough clean sludge pond.
Sterilization pool, the water outlet of settling tank again can be up to standard through sterilization, and the design adopts clorox sterilization.
Equipment room is mainly used in laying the equipment such as gas blower, nitrification liquid reflux pump, sludge reflux pump.
Although described the utility model with reference to several exemplary embodiment, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because the utility model can specifically be implemented in a variety of forms and not depart from spirit or the essence of utility model, so be to be understood that, above-mentioned embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in the claim of enclosing, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
