Description
Technical field
The utility model is about a kind of biochemical treatment system of petrifaction sewage, more particularly, and about a kind of biochemical processing device that can improve the petrifaction sewage of existing process equipment efficient.
Background technology
In the process system of existing petrifaction sewage biochemical treatment, owing to water quality, the water yield fluctuation of petrifaction sewage are larger, the pollutant load of difficult degradation is higher, causes not reaching requirement by the water after traditional petrifaction sewage biochemical treatment system processing.Concrete inaccessible requirement is owing to having the biochemical treatment system of petrifaction sewage now because the sludge organism in the second pond wherein is mutually unstable, sludge settling property is bad, cause out water suspension very high, and then make suspended substance take away large amount of organic, chemical oxygen demand (COD) (CODcr), total nitrogen content (TN), total phosphorous (TP) in the water are exceeded standard.
Summary of the invention
In view of shortcomings such as the biochemical treatment solid-liquid separation in the biochemical treatment system of present petrifaction sewage are difficult, sludge character is bad, the purpose of this utility model is to provide a kind of biochemical processing device of the petrifaction sewage that can effectively address the above problem.
The biochemical processing device of the petrifaction sewage in the utility model includes grille well, distributing well, homogeneous regulating tank, air supporting one heavy pond, hydrolysis acidification pool, biochemistry pool, aeration tank and the outlet sump that is communicated with successively by pipeline, is provided with air floatation machine and air supporting and promotes the pond between aeration tank and outlet sump.
Described air floatation machine includes the gentle floating box of the tubular reactor that is communicated with described aeration tank, and the cloth pool in described air supporting casing is provided with the polylith swash plate.
Described tubular reactor is communicated with air dissolved pump and the dissolving of input dissolved air water in described tubular reactor simultaneously.
The upper surface of described air floatation machine is provided be used to the slag scraper that strikes off dirt.
Described air floatation machine and air supporting promote between the pond and are provided with strainer.
The utility model build or the basis of built petrifaction sewage biochemical processing device on, substitute original air supporting second pond with air floatation machine, merged efficient air flotation technology, strengthen floc sludge floating function, existing treatment facility solid-liquid separation efficiency is significantly improved, and the SS water outlet reaches 5mg/L.To guaranteeing roles that plays up to standard such as CODcr, BOD5, TN, TP, and have the advantages such as high-level efficiency, reaction is fast, short, per ton water running expense of the residence time is low.For bad owing to air supporting second pond solid-liquid separation effect in the original equipment, sludge settling property is poor, goes out the problems such as water suspension exceeds standard and has carried out solving well.When improving solid-liquid separation efficiency, reduce investment outlay and produce considerable economic benefit.

Fig. 2 is the structural representation of dissolved air flotation device in the utility model.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is elaborated.
As shown in Figure 1, the biochemical processing device of the utility model China Petrochemical Industry sewage includes the grille well 1, distributing well 2, homogeneous regulating tank 3, air supporting one heavy pond 4, intermediate pool 5, hydrolysis acidification pool 6, biochemistry pool 7, aeration tank 8, intermediate pool 9, air floatation machine 10, the air supporting that are communicated with successively by pipeline and promotes pond 11 and outlet sump 19.Specifically petrifaction sewage is at first passed into grille well 1, the macrobead floating matter that utilizes grille well 1 to remove in the petrifaction sewage.The sewage of removing behind the macrobead floating matter enters distributing well 2 and homogeneous regulating tank 3 successively, and the water quality of sewage, PH etc. are regulated, and is convenient to the processing of follow-up equipment.
Sewage after being regulated by distributing well 2 and homogeneous regulating tank 3 enters the equipment that has acidication and two kinds of functions of anaerobic treatment in the biochemical processing device of petrifaction sewage concurrently, wherein two kinds of functions of acidication and anaerobic treatment are implemented by hydrolysis acidification pool 6 and air supporting one heavy pond 4 respectively, between hydrolysis acidification pool 6 and air supporting one heavy pond 4, be provided with intermediate pool 5, be used for regulating pondage, make the water yield fluctuation in the whole equipment steady.Enter in the biochemistry pool 7 by the sewage after hydrolysis acidification pool 6 processing, the stepping of going forward side by side enters aeration tank 8, and sewage is carried out de-carbon and nitration treatment.
Enter air floatation machine 10 through the sewage after de-carbon and the nitration treatment through lift pump 12, air floatation machine 10 includes the tubular reactor 13 gentle floating box 14 that are communicated with lift pump 12, and as shown in Figure 2, the cloth pool in air supporting casing 14 is provided with polylith swash plate 15.When sewage inlet pipe formula reactor 13, mix with the dissolved air water that is provided by air dissolved pump 16 and dissolving 17, make the pre-combination of pollutent in dissolved air water and the sewage, be beneficial to pollutent in the air supporting casing 14 interior abundant separation of air floatation machine 10.When sewage enter the air supporting casing 14 of air floatation machine 10 interior after fully with air-water mixture in the micro-bubble that discharges (bubble diameter scope 30～50um) is mixed, and these micro-bubbles stick on the flco in the sewage, and formation proportion is less than the air float body of water.Air float body rises to the water surface and is condensed into large pollutent, scrapes to slag receiving trough by the slag scraper 18 that is located at air floatation machine 10 upper surfaces and discharges.Enter simultaneously sewage in the air supporting casing 14 and further enter cloth pool in the air supporting casing 14, utilize the ripple swash plate 15 in cloth pool can make the dirt particles fast rise of less in the sewage and climb up on top of the water, the slower dirt particles that rises is separated in ripple swash plate 15, when dirt particles touches ripple swash plate 15, under the effect of buoyancy, it can rise against water (flow) direction, the particle that proportion is larger is deposited to the bottom of air floatation machine 10 through ripple swash plate 15, mud scraper output by the bottom makes the water outlet qualified discharge.Sewage by air floatation machine 10 outputs is exported through air supporting lift 11 and outlet sump 19.
Promote the strainer that is provided with between the pond 11 the further filtration of sewage do at air floatation machine 10 and air supporting in addition.
In sum, the water that enters in the utility model equipment is the petrochemical industry composite wastewater, can effectively remove the organism such as CODcr in the sewage, BOD5, TN, TP after processing through the biochemical processing device of petrifaction sewage.And by the tracking data analysis since the normal operation of equipment is shown, utilized air floatation machine 10 to substitute the residence time that has shortened solid-liquid separation behind the air supporting second ponds, and having increased processing efficiency, the SS water outlet reaches 5mg/L.
