Abstract
The utility model discloses a combined type oilfield produced water processing device which is designed in order to solve the technical problems in the existing processing devices. In the processing device, a produced water pipeline is connected to a cooling tower; an outlet of the cooling tower is communicated with a gas-floating oil-removal tank which is internally provided with an oil scraper, an oil collecting tank and a dissolved gas releasing pipe. The gas-floating oil-removal tank is communicated with a biological contact oxidation pond by a plurality of water distribution holes on the side wall; biological fillers are filled in the oxidation pond; an aerating device connected with a Roots blower is arranged on the bottom of the pond. The biological contact oxidation pond is connected sequentially with a settling pond, an intermediate water tank and a purified water pond, wherein wobble plate fillers are filled in the settling pond. The intermediate water tank is communicated with a double-filter-material filter through a pipeline and a booster pump; an outlet of the double-filter-material filter is communicated with the purified water pond by an ultraviolet sterilizer. The intermediate water tank is communicated with the dissolved gas releasing pipe by a multi-phase dissolved gas pump; the purified water pond is communicated with the double-filter-material filter by a backwashing pump. Due to the adoption of a combination of physical methods and bio-chemical methods, the medication is not required in a water processing process, the requirements on water quality and water temperature of inlet water are relented, and the adaptation is enhanced.

Embodiment
Embodiment:
With reference to Fig. 1, embodiment of the present utility model is further illustrated:
This treatment unit mainly comprises cooling tower 1, oil removal by air bubbling pond 2, biological contact oxidation pond 3, settling tank 4, intermediate water tank 5, force (forcing) pump 6, Double-filter material filter 7, ultraviolet sterilizer 8, purification water pool 9, heterogeneous air dissolved pump 10, roots blower 11, molten gas releasing tube 12, Oil scraper 13, collection tank 14, backwashing pump 15, water distributing pore 16, aerating apparatus 17, biologic packing material 18, recovered water pipeline 19, by-pass valve 20 and inclined plate packing 21;
The recovered water pipeline 19 that thermometer is housed connects cooling tower 1, and cooling tower 1 outlet and 19 of recovered water pipelines are provided with by-pass valve 20, and cooling tower 1 outlet is communicated with oil removal by air bubbling pond 2.2 tops, oil removal by air bubbling pond are provided with Oil scraper 13, and sidewall is provided with collection tank 14, and bottom is provided with molten gas releasing tube 12.Oil removal by air bubbling pond 2 is communicated with biological contact oxidation pond 3 by the water distributing pore 16 on sidewall, is provided with biologic packing material 18 in oxidation pond, is provided with the aerating apparatus 17 that connects roots blower 11 at the bottom of pond.Biological contact oxidation pond 3 is established settling tank 4, intermediate water tank 5 and the purification water pool 9 of inclined plate packing 21 in succession connecting successively.Intermediate water tank 5 is communicated with Double-filter material filter 7 by pipeline and force (forcing) pump 6, and Double-filter material filter 7 outlets are communicated with purification water pool 9 through ultraviolet sterilizer 8.Intermediate water tank 5 is communicated with molten gas releasing tube 12 through heterogeneous air dissolved pump 10, and purification water pool 9 is communicated with Double-filter material filter 7 through backwashing pump 15.
The method of work of this treatment unit is as follows:
One. it is cooling that oil field extracted water is introduced into the cooling tower 1 of open type, makes water temperature be down to the 25-30 ℃ of suitable microorganism growth, if come water temp lower than 30 ℃, can directly by by-pass valve 20, enter oil removal by air bubbling pond 2.Then, adopt dissolved air flotation process to draw water from intermediate water tank 5, at heterogeneous air dissolved pump 10 import air amounts, in the pump housing, carry out high pressure solution gas, make the high pressure saturated dissolved gas water 2 front end decompressions in oil removal by air bubbling pond that form, discharge the microbubble of a large amount of diameter 30-50 μ m, adhere to oil droplet, float up to liquid level, and scrape into collection tank 14 and reclaim by Oil scraper 13.The not dosing of whole air supporting process of produced water disposal, floatation reflux, than 15-30%, stays approximately 15 minutes time, the about 50-80mg/L of water outlet oil-containing in pond.
