Description
Technical field
The utility model relates to a kind of water treatment plant, the sanitary treating arrangement of suspended matter 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 plant of using always, and it is comparatively desirable for the purification of water quality of suspended matter proportion about 1.The structure of traditional airfloat equipment as shown in Figure 1, it comprises flotation tank, water inlet 1 place at flotation tank is equipped with chemicals dosing plant, the air-flotation reactor of flotation tank is connected with dissolved air water import 2, airfloat equipment mainly is by penstock and pressure air, in molten cylinder, fully mix, 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 matter or the oils, make it volume and increase and float, regularly the scum silica frost of removing come-up by Slag Scraping Device 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 (flocculant) 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 purpose of this utility model is to need to drop into a large amount of medicaments at existing cross-flow type air-floating apparatus in water treatment procedure to improve treatment effect, cause the high problem of operating 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.
The technical solution of the utility model is:
A kind of cross-flow type air-floating apparatus based on electrocoagulation, it comprises flotation tank 8, flotation tank 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 inlet 1 and dissolved air water import 2, the bottom of collecting chamber 10 is equipped with perforation collector pipe 3, the water side of perforation collector pipe 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 flocculant.
The anode of described electrocoagulation device 7 is a metallic aluminium, and negative electrode is a stainless steel sheet.
The top of described collecting chamber 10 is equipped with Slag Scraping Device 6 and ash pit 4
The beneficial effects of the utility model:
The aluminium hydroxide that the utility model utilizes electrolysis principle to produce replaces flocculant, and it is low to have a cost, is easy to realize, saves the advantage of operating cost, can save operating cost more than 60%.
The utility model is simple in structure, the treatment effeciency 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 utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 2.
A kind of cross-flow type air-floating apparatus based on electrocoagulation, it comprises flotation tank 8, flotation tank 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 inlet 1 and dissolved air water import 2, the bottom of collecting chamber 10 is horizontally-arranged perforation collector pipe 3, the top of collecting chamber 10 is equipped with Slag Scraping Device 6 and ash pit 4, the water side of perforation collector pipe 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 flocculant, 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 flocculation so that produce aluminium ion during electrolysis with hydroxide ion in the brine electrolysis, and negative electrode can adopt the stainless steel sheet that is difficult for corrosion.Electrocoagulation cross-flow type air supporting of the present utility model is handled the water yield and is generally 5～200m
3/ h.
The utility model utilizes electrocoagulation to produce flocculation, can omit the former chemicals dosing plant that adds flocculant, no medicament expense and no longer need use medicine system in the treating process.
Electrocoagulation is to utilize electrochemical method to produce hydroxide as flocculant, groundwork is: former water is passed through the electrocoagulation device, knockouts is provided with two electrodes, anode is that aluminium, negative electrode are corrosion-resistant steel, after connecting direct current (DC), the anode aluminium 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 floccus.The floccus that generates is by bonding numerous air-bubble come-up behind the dissolved air water, and clear water is collected in the clear water reserviors bottom and used, and the top body refuse is regularly removed to send in the ash pit 4 with Slag Scraping Device 6 and discharged outside the flotation tank.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
