Abstract
The utility model discloses an oily sewage treatment system, which comprises an adjusting oil separation tank, a pressurizing vessel air flotation tank, an oil-water separator, a sequencing batch reactor activated sludge process (SBR) reaction tank and a filter connected in turn through pipelines, wherein the water inlet pipeline of the pressurizing vessel air flotation tank is connected with a chemical agent tank and a lift pump in turn. A three-stage treatment process of combining a gravity oil-water separation method, an air flotation method and a biological method is adopted in the system; and after the oily sewage is treated, various pollutant indexes can reach the related emission standards. Moreover, the oily sewage treatment system also has the advantages of low process cost, large treatment quantity, stable effect and the like.
Description
Technical field
The utility model relates to technical field of sewage, is specifically related to a kind of oil depot oil-containing sewage treatment system.
Background technology
Along with the pay attention to day by day of country to environment protection industry, use oil-containing sewage treatment technique and help environment protection, can significantly reduce the pollution of sewage to environment.At present, the most of oil depot of China can only adopt oil trap simply the productivity oily(waste)water to be done initial gross separation, and the sewage after the separation still can not reach emission standard fully.Both at home and abroad several oil-contaminated water processing methods that oil depot is commonly used comprise: physics normal gravity partition method, centrifugal separation, coarse method and membrane separation process, physico-chemical processes (air supporting method), chemical method (coacervation and salting-out process), biological process (plough method, compost treatment method and sludge organism reactor method) etc.As adopt two or more method to handle, and can satisfy oil depot oily(waste)water emission standards better, prevent the environmental pollution that the oil depot oily(waste)water causes.
Summary of the invention
The purpose of this utility model is to provide a kind of oil-containing sewage treatment system that can satisfy oil depot oily(waste)water emission standard better.
For achieving the above object, technical solutions of the utility model are as follows:
Oil-containing sewage treatment system, comprise the adjusting oil trap, pressurizing vessel air flotation pool, water-and-oil separator, SBR (sequence intermittent activated sludge process) reaction tank and the strainer that connect successively by pipeline, be connected with chemical agent jar and lift pump on the suction culvert of described pressurizing vessel air flotation pool in turn.
Principle of work of the present utility model is: because oil tank deposits and pollutent severe overweights such as cleaning of evaporator water PetroChina Company Limited.'s class and SS, therefore earlier oily(waste)water is introduced and regulated oil trap, carry out rough oil removing and SS in the adjusting oil trap; On pressurizing vessel air flotation pool suction culvert, add chemical agent, and the lifting of process lift pump, chemical agent and sewage are fully mixed, enter the pressurizing vessel air flotation pool then; Under fine and closely woven molten gas bubbles entrain, the tiny oil particles in the sewage, suspended substance combine with chemical agent and float, and make oily water separation, and air-floating apparatus can make 85% oil and 80% suspended substance obtain pre-treatment; The water that comes out through the pressurizing vessel air flotation pool enters water-and-oil separator or shell strainer absorption impurity again, removes oil content, and the sewage that comes out from water-and-oil separator enters the sbr reactor pond, the bacterium and the BOD that contain in can well disposing of sewage
5Deng, through can directly discharging after the water process filter filtration after the processing of sbr reactor pond.
Advantage of the present utility model is:
The tertiary treatment technology that adopts gravity oily water separation method, air supporting method to combine, oily(waste)water with biological process after treatment, every pollutent index all can reach the first discharge standard in " integrated wastewater discharge standard (GB8978-1996) "; Oil-containing sewage treatment system of the present utility model is not only saved the technology cost, and treatment capacity is big, effect stability.
Description of drawings
Fig. 1 is the utility model structural representation
1, regulates oil trap; 2, pressurizing vessel air flotation pool; 3, water-and-oil separator; 4, sbr reactor pond; 5, strainer; 6, chemical agent jar; 7, lift pump.
Embodiment:
In order to make the utility model easy to understand, further set forth the utility model below in conjunction with accompanying drawing.
See accompanying drawing 1: oil-containing sewage treatment system comprises adjusting oil trap (1), pressurizing vessel air flotation pool (2), water-and-oil separator (3), sbr reactor pond (4) and the strainer (5) that connects successively by pipeline, is connected with chemical agent jar (6) and lift pump (7) on the suction culvert of described pressurizing vessel air flotation pool (2) in turn; Wherein the available shell strainer of water-and-oil separator (3) replaces.
When system uses, oily(waste)water is introduced regulated oil trap (1) earlier, carry out rough oil removing and SS in the adjusting oil trap; Then, on pressurizing vessel air flotation pool (2) suction culvert, add chemical agent by chemical agent jar (6), and the lifting of process lift pump (7), chemical agent and sewage are fully mixed, enter pressurizing vessel air flotation pool (2) then; Under fine and closely woven molten gas bubbles entrain, the tiny oil particles in the sewage, suspended substance combine with chemical agent and float, and make oily water separation, and the pressurizing vessel air flotation pool can make 85% oil and 80% suspended substance obtain pre-treatment; The water that comes out through the pressurizing vessel air flotation pool enters water-and-oil separator (3) or shell strainer absorption impurity again, removes oil content, and the sewage that comes out from water-and-oil separator enters sbr reactor pond (4), the bacterium and the BOD that contain in can well disposing of sewage
5Deng, through can directly discharging after water process filter (5) filtration after the processing of sbr reactor pond.
Description in the foregoing description and the specification sheets has just illustrated principle of the present utility model, and under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
