In order to further illustrate the constitutional features of a kind of integrated sewage disposal device 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 kind of integrated sewage disposal device 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, after mixing, flows into equalizing tank with the sewage from catering business of processing through air supporting oil removal;
(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, water separation and deslagging function on traditional oil trap basis, 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 the steps such as rising, oil-scraping device be separated and form.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, because sticky and volume density are less than water, float to the water surface, thus make in water greasy dirt with solid particulate by the separated removal of automatic wiping device.
Wherein, grid is installed in frame trough.Grid is mainly used to tackle the agglomerate floater in sewage, to guarantee the normal operation of subsequent disposal structures and effectively to alleviate, processes load, 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 while regulating pondage and homogenizing water quality.
The built-in submersible sewage pump of equalizing tank and backflow measure, to guarantee that certain rated flow is promoted to subsequent biological treatment system, reduce the impact load of the water yield to system.For guaranteeing in equalizing tank not deposit dirt, establish perforated pipe aerating regulation stirring system simultaneously, realize anoxic also as denitration pond in advance.
Integrated MBBR 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 that just degrades when these polyP bacterias enter Aerobic Pond and store in body, generate energy, for the synthetic of cell with inhale phosphorus, absorbs the phosphorus containing sludge that phosphorus in sewage forms high density, discharges system, thereby reach the object of dephosphorization with excess sludge.
The major function of anoxic pond is denitrification denitrogenation.Denitrifying bacteria at dissolved oxygen concentration, under extremely low or anaerobic conditions, can utilize nitrate in nitrogen as electron acceptor(EA) oxidation of organic compounds, the nitrogen in nitrate is reduced into nitrogen, thereby completes the denitrification process of sewage.In pond, establish perforated pipe intermittent aeration and realize anoxic.In this embodiment, in this anaerobic pond, be provided with carbon source disrupter, in carbon source disrupter, add carbon source, thereby promote anti-nitration reaction.Described carbon source can be the stalk of pulverizing, and rice husk etc. are preferred, the carbon source of pulverizing can be made into a certain size ball, then drop in carbon source disrupter.
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
2the stable materials such as O.When organism is oxidized, the organonitrogen in sewage is also oxidized to ammonia nitrogen, the in the situation that, mud sufficient at dissolved oxygen age being longer, is further oxidized to nitrite and nitrate.
Sewage flows into settling tank after biochemical treatment, realizes mud-water separation.In pond, sludge reflux system is installed simultaneously, the active sludge in pond is partly drained into integration apparatus anaerobic zone by return sludge pump.Excess sludge regularly enters sludge sump.
After the regularly outward transport of mud in sludge sump, need to further clean, now open air-blast device, and the water in clean water basin is arranged into sludge sump, thereby sludge sump is cleaned thoroughly.
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.
