A kind of cross-sectional figure that Fig. 1 provides for the embodiment of the present invention 1.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
As shown in Figure 1, the present embodiment discloses a kind of oil-contained waste water treatment device, comprises air flotation pool 100, storage slag bath 200, strainer 300, electrooxidation module, electric flocculation reactor 700 and the power supply 500 that electric power is provided for each device; Air flotation pool 100 is communicated with electric flocculation reactor 700 and storage slag bath 200 simultaneously; Electricity flocculation reactor 700 is communicated with the electrooxidation module by strainer 300; The top of air flotation pool 100 is provided with oil-isolating device 210.
Wherein, the electrooxidation module comprises electrochemical oxidation reactions device 410 and comprises the feeding device that electrooxidation charging pump 420, machine mixer 440, drug dissolving tank 430, dosing volume pump 450 are combined into; Electrochemical oxidation reactions device 410 connects feeding device; Machine mixer 440 is arranged in drug dissolving tank 430, and electrooxidation charging pump 420 connects drug dissolving tank 430 by dosing volume pump 450.
Wherein, the strainer in the present embodiment can be deep bed filter, is convenient to disassembly, cleaning.
Principle of the present invention is as follows: the flocculation of (1) electricity
Electricity flocculation is to utilize metal hydroxides flocculation that soluble metal anode produces in electrolytic process to remove the water technology of pollutant in water.Reality Anodic material adopts the cheap metals such as aluminium or iron usually.Take iron as example, its elementary process is as follows:
Anodic reaction: Fe+2e → Fe2+
Cathodic reaction: 2H2O+2e → H2 ↑+2OH-
Hydrolysis reaction: Fe2++2OH-→ Fe (OH) 2 ↓
The ferrous hydroxide flco that the ferrous ion that anode electrolysis produces produces in hydrolytic process has good flocculation, absorption property, can effectively remove the pollution substances such as water-borne glue body, larger molecular organics and oils, thereby reduces waste water COD.
Adopt electric flocculation process to process breakdown of emulsion (flocculation) effect that oily(waste)water can effectively be brought into play electric flocculation process, remove the oily substance in oil extraction waste water, the ferrous ion (iron ion) that simultaneously electrolysis produces can with oil extraction waste water in sulfonium ion form Iron sulfuret (iron sulphide) precipitation, and can remove simultaneously suspended solids and colloidalmaterial in waste water.
(2) electrochemical oxidation
Catalytic oxidation is the organism that utilizes in strong oxidizing property material (as hydroxyl radical free radical, antozone etc.) the Oxidative demage waste water that the steady electrode of shape with catalytic performance produces under the energising electrolytic condition, generate carbonic acid gas and water, thereby reduce the treatment process of COD value of waste water.The dimensional stable anode that catalytic oxidation adopts mainly comprises Graphite Electrodes, platinized electrode, titanium base ruthenium dioxide (iridium) electrode, ti-supported lead dioxide electric pole and titanium base stannic oxide electrode.Wherein ti-supported lead dioxide electric pole is best because of catalytic performance in the organic matter degradation field, current efficiency is the highest, the good stability widespread use.
Adopt dissolved organic matter in catalytic oxidation art breading oily(waste)water energy degrading waste water, comprise the aromatics of difficult for biological degradation, effectively remove COD and colourity, make discharged wastewater met the national standard.
The above technical scheme that the embodiment of the present invention is provided is described in detail, used specific case herein principle and the embodiment of the embodiment of the present invention are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the present invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the present invention, all will change on embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
