Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1-3, the utility model includes an electrocoagulation that can remove suspended impurity, pigment and heavy metal in water removal
Device 1 is connected with a floating washing slot 2 after the collection surface of the electrocoagulation device 1, is connected with after the floating washing slot 2 by a pump 3
Filter 4, the electrocoagulation device include collection surface 5, the coagulation unit 100 being arranged in inside collection surface 5 and partition, the partition
Including water inlet plate 101, deflector 102 and water outlet plate 103, the setting of coagulation unit 100 is in deflector 102 and water outlet plate
Between 103.
Coagulation unit includes the cathode 7 and anode 8 of external rectifier power supply, and the filter 4 is double-layer filter material filtering
Device.
Wherein, rectifier 6 is the automatic fairing of falling pole that one kind can arbitrarily be adjusted within the scope of 0-30 minutes;It is described
Two-layer filter be one with recoil cleaning device mechanical type filter.
Wherein, water inlet plate 101 and water outlet plate 103 are connect with the bottom of collection surface 5, the top of the deflector and collection surface
Portion's connection, the water inlet plate are arranged on the left of deflector, and the water outlet plate is arranged on the right side of deflector, and the anode 8 uses aluminium
Material is made, and the anode 8 is annular in shape, and side is provided with opening, and between 30-60 degree, the cathode 7 is arranged openings of sizes
In the inside of anode 8, i.e. the center point.
Raw water 9 to be processed enters collection surface 5 through flowmeter 10 with specified flow, flow velocity, while rectifier 6 inputs directly
Galvanic electricity field is handled, and treated, and water flows into the further cohesion floating washing of floating washing slot 2, then inputs Two-layer filter with pump 3
Filtering, water outlet after filtering are limpid water purification.
The utility model using metal aluminum sheet as electrode, when DC power supply connect after, anode metal dissolution, metal ion into
Enter in water, i.e., AI-3e-AI3+ water is by electrolysis H2O → H++OH-.
Positively charged hydrogen ion obtains electronics on cathode becomes hydrogen 2H++2e → H2, and the hydrogen of negative electrical charge is had in solution
The oxygen radical ion Ghandler motion that faces south is dynamic, and in anode discharge, i.e. 4OH- -4e → 2H2O4+2 [0].
After hydroxide ion electric discharge, new nascent oxygen is generated, oxygen bubble is generated in anode, in the hydrogen that cathode generates
Bubble takes suspended matter to the water surface, forms scum layer on the water surface when these bubbles rise, and the substance for taking the water surface to is more, floats
The closeer slag blanket the thicker, then removes dross;Simultaneously under the conditions of pH is greater than 3.8, AI3+ is reacted with OH- again generates AI [OH]
Precipitating, i.e. AI3++30H- → AI [OH] 3.
The suspended particles reacted in the aluminium hydroxide and water generated generate flocculate, just float and divide when flocculate specific gravity is small
From, than it is great when with regard to precipitation and separation.
