Embodiment
Below in conjunction with Figure of description, the utility model is described further.
Oil-contained waste water treatment device of the present utility model, as shown in Figure 1, it comprises sewage lagoon 1, contaminated-oil basin 2, monitoring pool 3, automatic control system 4, also comprise the floating type intake 5, pretreater 6, the water-oil separator that by pipeline, are connected successively, in pipeline, be provided with water pump 7, pretreater 6, water-oil separator are provided with by pipeline and connect to the oil discharge outlet of contaminated-oil basin 2 and connect to the sewage draining exit of sewage lagoon 1 by pipeline, water-oil separator is provided with by pipeline and connects to the water port of monitoring pool 3, and water pump 7, pretreater 6, water-oil separator are controlled by automatic control system 4.
Concrete: water-oil separator comprises the strainer that is controlled by automatic control system 8, gravity separator 9, coalescing separator 10, the adsorption filter 11 being connected successively by pipeline, and water port is located on adsorption filter; On the sewage draining exit of pretreater 6, water-oil separator, be connected with wash water valve 12; On strainer 8, gravity separator 9, coalescing separator 10, there is gathering room, gathering room is provided with oil discharge outlet, on oil discharge outlet, be connected be controlled by automatic control system 4 and by pipeline, connect the magnetic valve 13 to contaminated-oil basin 2, gathering room is equipped with the fuel level sensor 14 to automatic control system transmitted signal.In water port, be connected with sampling valve 15.Pump 7 is two, lays respectively between floating type intake 5 and pretreater 6, between pretreater 6 and water-oil separator.Floating type intake 5 and establish strainer 16 between the pump of upstream.All component part integrated installations except floating type intake of this device at a sledge dress base 17(referring to Fig. 2, Fig. 3) go up or movable base on.Automatic control system also comprises the liquid level sensor being placed in sewage lagoon.
Pretreater can adopt gerotor type or pressure-bearing type.Pretreater, according to the shallow layer precipitating principle of discrete particles, adopts inclined tube separating technology (inclined tube separator) except oils and suspended solids in anhydrating, by tube settling method, changes coprecipitation mode to improve removal efficiency.Thereby reaching former water oil-contg and suspension content changes outlet effect without negative impact; Equipment volume is light, size is little; Simple in structure, without consumable accessory, without moving dynamic component, process cost is low.
The in-built contamination capacity of strainer tank body is large, long service life, filter core that filtering accuracy is high; sewage enters after strainer, and thicker particle can get off because of inertia sedimentation, and thinner particle is tackled by cartridge surface; sewage after filtration, through rising pipe line outflow filter, enters gravity separator.Along with filtration time increases, the pollutent being deposited on filter core is more and more, and strainer inlet outlet pressure differential rises gradually, when rising to maximum permission operting differential pressure (0.2MPa), illustrates that filter core is blocked, need to change in time.Strainer is as the protective device of coalescing separator; need to there is higher filtering accuracy; to filter, remove tiny suspended contamination (> 10 μ m); prevent from take particle as core can not breaking milk and removing oil; effectively the work-ing life of Coalescence filter core and absorption filter element in prolongation follow-up equipment, reduce the effect of operation expense.
Gravity separator utilizes the characteristic of its long flow path, tiny elaioleucite is fully contacted and grow up gradually and float, oil over 80% is aggregated discharge in this one-level, only have the seldom tiny elaioleucite of amount to be transported in coalescing separator, so gravity separator can extend the work-ing life of Coalescence filter core greatly.
The in-built Coalescence filter core of coalescing separator utilizes special super-fine fiber material connecting inner structure design cleverly, oil in water emulsion breakdown of emulsion trickle in water is also progressively agglomerated into large oil droplet, float up to gathering room, by oil discharge outlet, automatically discharged, the water oleaginousness≤5mg/L discharging after processing.
Adsorption filter adopts activated carbon adsorption device, be mainly used in the advanced treatment of industrial sewage, its function realizes and realizing by absorption filter element, activated carbon granule is housed in absorption filter element, activated carbon particle has very many micropores and huge specific surface area, organic pollutant in water is had to very strong physical adsorption ability, can effectively reduce organic content in water, COD, colourity, peculiar smell etc., realize the object of water quality advanced processing.The principle of operation of activated carbon adsorption device is basic identical with strainer, and adsorption filter is imported and exported and is provided with differential pressure indicator, when pressure reduction reaches maximum 0.2MPa, shows the contaminated thing obstruction of activated carbon adsorption filter core, should take out replacing.
Automatic control system can arrange manually and automatic two kinds of operating mode.On the panel of controlling box, be provided with start-stop button, draining valve and working station indicator.The automatic control system adopting according to the difference of pretreater is also different.
Sump pump adopts single screw rod.
This device aspirates sewage from sewage lagoon top layer by floating type intake.During automatic operation, only have while putting on sewage lagoon liquid level arrives liquid level sensor, pump could automatic operation, and when sewage lagoon liquid level drops to while putting under sensor, pump quits work automatically, installs in the course of the work the oil level automatic-discharging sump oil according to each gathering room.
Water flow-path, oily flow process and the mud flow process of device are described below:
water flow-path: oily(waste)water is through floating type intake → sump pump → pretreater → strainer → gravity separator → coalescing separator → adsorption filter → monitoring pool → discharge after the assay was approved;
oil flow process: the sump oil of discharging in this device busy process flows into contaminated-oil basin after oil header is concentrated.Its flow process is: pretreater, strainer, gravity separator, coalescing separator → contaminated-oil basin.Sump oil in contaminated-oil basin should regularly be recycled;
mudflow journey: owing to containing a certain amount of silt in oily(waste)water, the processing unit before strainer and flow process thereof, after operation for some time, can produce a certain amount of settling, should be according to water quality and running condition, and periodic blow down is to sewage lagoon.
Oil-contained waste water treatment device of the present utility model has following characteristics:
(1) effluent quality is good: the effluent quality after primary treatment meets or exceeds first discharge standard (oleaginousness is less than 5mg/L);
(2) full Physical is processed oily(waste)water: in use, do not stir, not dosing, non-secondary pollution recyclable sump oil;
(3) energy consumption is low, energy-saving effect is obvious: the current consumption of processing 1 cubic metre of sewage is not more than 1 degree electricity;
(4) compact construction, whole plant take integrated installation on a base;
(5) easy to use: user can select manually and automatic operation mode according to requirements, widely applicable;
(6) automatization level is high, can realize unmanned, and labour intensity is little;
(7) install fast: on-the-spot installation only needs to connect four exterior lines and power supply and/or signal cable;
(8) the anti-hazard classification of electric installation meets the requirement of explosion proof of oil depot district to electric installation.
