In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is further introduced and explanation.
Embodiment
The treatment facility of oily(waste)water comprises air supporting grease trap, connects the integrated sewage treatment case of air supporting grease trap, and the anaerobic pond in integrated sewage treatment case is connected with air supporting grease trap, and the water inlet of anaerobic pond is positioned at the bottom of anaerobic pond.It should be noted that, oily water need pass through coarse grid conventionally, thin grid carries out coagulation, after suspended matter in removal sewage and partial organic substances, enter again air supporting grease trap, and air supporting grease trap slag, water separation and deslagging function, air supporting function and automatic wiping function have been increased on the basis of traditional oil trap.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.Air supporting grease trap in the present embodiment adopts Guangzhou Heng De Environmental Protection Technology Co., Ltd, the air supporting grease trap of HDG-ZQ-A-0.83 model.
Integrated sewage treatment case as shown in Figure 1-2, comprises anaerobic pond 1, anoxic pond 2, Aerobic Pond 3, inclined-plate clarifying basin 4, clean water basin 5, sludge sump 6.
Anaerobic pond 1 is circular pond, and anoxic pond 2 is to have the annular pool of phase concentric with anaerobic pond 1, and anaerobic pond 1 is positioned at anoxic pond 2 inside, and anoxic pond 2 is positioned at Aerobic Pond 3 inside; The first overflow weir 7 is positioned at anaerobic pond 1 top, and the Chi Kou of anaerobic pond 1 is in the first overflow weir 7, and sewage can overflow to from the Chi Kou of anaerobic pond 1 the first overflow weir 7; The first overflow port 8 is positioned at the bottom of the first overflow weir 7, is communicated with the first overflow weir 7 and anoxic pond 2; The first connected entrance 9 is communicated with the bottom of anoxic pond 2 and Aerobic Pond 3; The second overflow weir 12 is positioned at Aerobic Pond 3, and sewage can overflow to the second overflow weir 12 from Aerobic Pond 3; The second overflow port 13 is positioned at the bottom of the second overflow weir 12, is communicated with inclined-plate clarifying basin 4 and the second overflow weir 12.
The first aeration tube 10 adopts continous way aeration, and aeration aperture is 2-5mm, is located at the bottom of Aerobic Pond 3; The second aeration tube 11 adopts continous way aeration, and aeration aperture is 0.8-2mm, is located at the middle part of Aerobic Pond 3; The 3rd aeration tube 18 adopts intermittent aeration, and aeration aperture is 0.8-2mm, is located at the bottom of anoxic pond 2.
The 3rd overflow port 14 is communicated with the top of inclined-plate clarifying basin 4 and clean water basin 5; The second connected entrance 15 is communicated with the bottom of inclined-plate clarifying basin 4 and sludge sump 6; Water port 16 is positioned at the bottom of clean water basin 5, and mud discharging mouth 17 is positioned at the bottom of sludge sump 6.
Oily water treatment flow process: oily water enters after the processing of air supporting grease trap, from being positioned at the water inlet of anaerobic pond 1 bottom, enter anaerobic pond 1, from the Chi Kou of anaerobic pond 1, overflow to the first overflow weir 7 again, by the first overflow port 8, enter anoxic pond 2, from the first connected entrance 9, enter Aerobic Pond 3 again, the sewage overflow of processing in Aerobic Pond 3 is to the second overflow weir 12, by the second overflow port 13, enter settling tank 4, the upper strata clear water sinking after determining overflows to clean water basin 5 through the 3rd overflow port 14, and the lower floor's mud after precipitation is discharged to sludge sump 6 by the second connected entrance 15.
Principle of work of the present utility model is: oily water, after promoting, utilizes coarse grid, thin grid to carry out coagulation, removes suspended matter and partial organic substances in sewage.Sewage after coagulation enters air supporting grease trap, bubble generator in air supporting grease trap makes to produce in water a large amount of micro bubbles, thereby form 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 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.
Sewage after air supporting grease trap is processed in the mode of low in and high out successively through anaerobic pond, anoxic pond, Aerobic Pond, and utilize the setting of the ring structure of anaerobic pond, anoxic pond and the overflow port position in each pond, realize water inlet automatic stirring anaerobic pond and anoxic pond, guarantee that sewage evenly mixes and reaches the object that stops enough time in anaerobic pond, anoxic pond at anaerobic pond and anoxic pond, is fully degraded greasy dirt.Wherein, in anaerobic pond, polyP bacteria absorbs the phosphorus in sewage, forms the phosphorus containing sludge of high density, discharges system, thereby reach the object of dephosphorization with excess sludge; In anoxic pond, add denitrifying bacteria to complete the denitrification process of sewage, and this process need guarantee dissolved oxygen concentration≤0.5mg/L in anoxic pond, and nitrifier oxygen content in denitrification process can make sewage is more and more lower, therefore intermittently type micro-hole aerating apparatus is installed in anoxic pond bottom, carry out aeration; In Aerobic Pond, add MBBR (MBBR), and adopt novel biological suspended packing to be convenient to a large amount of attached growth of microorganisms, thereby carry out efficient biological degradation, reach the object of removing pollutent.The oxygen that this process need consumption is a large amount of, therefore in Aerobic Pond bottom, continous way aerating apparatus is set and carries out continuous aeration, but the bubble producing due to aeration tube in sewage in uphill process oxygen be constantly consumed, make microorganism in the sewage of upper strata can not get enough oxygen, therefore at Aerobic Pond middle part, another more energy-conservation continous way microporous aeration device is set and carries out aeration.Sewage after Aerobic Pond is processed enters settling tank and carries out mud, water separation, and after precipitation, upper strata clear water is discharged to clean water basin, and bottom mud regularly drains into sludge sump.
Through the sewage of this device processes, effluent quality can reach < < urban wastewater treatment firm pollutant emission standard > > (GB18918-2002) one-level B standard.
The above only further illustrates technology contents of the present invention with embodiment, so that reader is easier to understand, but does not represent that embodiments of the present invention only limit to this, and any technology of doing according to the present invention is extended or recreation, is all subject to protection of the present invention.
