Description

Cross-flow type air-floating apparatus based on electrocoagulation
Technical field
The present invention relates to a kind of water treatment device, the waste disposal plant of suspended substance proportion about 1 in especially a kind of water, specifically a kind of cross-flow type air-floating apparatus based on electrocoagulation.
Background technology
As everyone knows, airfloat equipment is that all kinds of water technologies are water treatment device of using always, and it is comparatively desirable for the purification of water quality of suspended substance proportion about 1.The structure of traditional airfloat equipment as shown in Figure 1, it comprises air flotation pool, water-in 1 place at air flotation pool is equipped with chemicals dosing plant, the air-flotation reactor of air flotation pool is connected with dissolved air water import 2, airfloat equipment mainly is by pressure water and pressure air, thorough mixing in molten cylinder, suddenly decompression discharges again, enter from molten gas import 2 and to discharge countless tiny bubbles in the air-flotation reactor, bubble can be adsorbed in uphill process on suspended substance or the oils, make it volume and increase and float, regularly the scum silica frost of removing come-up by slag scraper 6 is discharged from ash pit 4, and all the other water that clean are relatively collected by the collecting chamber bottom.
For improving the suspended substance removal effect, need when water inlet, add medicament (flocculation agent) usually and form alumen ustum, be beneficial to the come-up effect, medicament expense accounts for more than 60% of whole service expense.If can be by other physicochemical method with medicament then to the conserve water processing cost, prevent that medicament Disabled from staying not, increasing water quality has great importance, and to this, does not still have the solution of getting well at present.
Summary of the invention
The objective of the invention is in water treatment procedure, to need to drop into a large amount of medicaments and improve treatment effect at existing cross-flow type air-floating apparatus, cause the high problem of running cost, design a kind of cross-flow type air-floating apparatus that medicament can reach removal suspended impurity purpose that need not to add based on electrocoagulation.
Technical scheme of the present invention is:
A kind of cross-flow type air-floating apparatus based on electrocoagulation, it comprises air flotation pool 8, air flotation pool 8 is divided into air-flotation reactor 9, collecting chamber 10 and clean water chamber 11 by the dividing plate of installing in the pond, air-flotation reactor 9 is connected with water-in 1 and dissolved air water import 2, the bottom of collecting chamber 10 is equipped with perforation header 3, the water side of perforation header 3 communicates with clean water chamber 12, the top of clean water chamber 12 is provided with water outlet 5, it is characterized in that in described air-flotation reactor, a side of dissolved air water import 2 is equipped with the electrocoagulation device 7 that can electrolysis produces flocculation agent.
The anode of described electrocoagulation device 7 is a metallic aluminium, and negative electrode is a stainless steel plate.
The top of described collecting chamber 10 is equipped with slag scraper 6 and ash pit 4
Beneficial effect of the present invention:
The aluminium hydroxide that the present invention utilizes electrolysis principle to produce replaces flocculation agent, and it is low to have a cost, is easy to realize, saves the advantage of running cost, can save running cost more than 60%.
The present invention is simple in structure, the processing efficiency height, and no medicament Disabled stays.
Description of drawings
Fig. 1 is the structural representation of existing cross-flow type air-floating apparatus.
Fig. 2 structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 2.
A kind of cross-flow type air-floating apparatus based on electrocoagulation, it comprises air flotation pool 8, air flotation pool 8 is divided into air-flotation reactor 9 by the dividing plate of installing in the pond, collecting chamber 10 and clean water chamber 11, air-flotation reactor 9 is connected with water-in 1 and dissolved air water import 2, the bottom of collecting chamber 10 is horizontally-arranged perforation header 3, the top of collecting chamber 10 is equipped with slag scraper 6 and ash pit 4, the water side of perforation header 3 communicates with clean water chamber 12, the top of clean water chamber 12 is provided with water outlet 5, in described air-flotation reactor, one side of dissolved air water import 2 is equipped with the electrocoagulation device 7 that the energy electrolysis produces flocculation agent, as shown in Figure 2, the anode of electrocoagulation device 7 can adopt aluminium block, aluminium bar or aluminum strip combine the aluminium hydroxide that formation has throwing out so that produce aluminum ion during electrolysis with hydroxide ion in the brine electrolysis, and negative electrode can adopt the stainless steel plate that is difficult for corrosion.Electrocoagulation cross-flow type air supporting of the present invention is handled the water yield and is generally 5~200m 3/ h.
The present invention utilizes electrocoagulation to produce throwing out, can omit the former chemicals dosing plant that adds flocculation agent, no medicament expense and no longer need use medicine system in the treating processes.
Electrocoagulation is to utilize electrochemical method to produce oxyhydroxide as flocculation agent, ultimate principle is: former water is passed through the electrocoagulation device, knockouts is provided with two electrodes, anode is that aluminium, negative electrode are stainless steel, after connecting direct current, the anode aluminum ion enters the hydroxide radical that produces with catholyte in the water and forms alumine hydroxide colloid, and the long-pending grain of absorption impurity, generates floss.The floss that generates is by bonding numerous air-bubble come-up behind the dissolved air water, and clear water is collected in the clean water basin bottom and used, and the top body refuse is regularly removed to send in the ash pit 4 with slag scraper 6 and discharged outside the air flotation pool.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
