Fig. 2 is the utility model A-A sectional view;
Fig. 3 is the utility model B-B sectional view.
Embodiment
For further setting forth the utility model, be to reach technique means and the effect that predetermined utility model object is taked, below in conjunction with accompanying drawing and preferred embodiment, to foundation embodiment of the present utility model, structure, feature and effect thereof, be described in detail as follows:
As Figure 1-3, dyeing waste-water contact break dechromisation treatment unit described in the utility model, is disposed with water inlet pipe (8), electrolyzer (13) and effluent trough (3) from top to bottom.
On water inlet pipe (8), be connected with some water distributors (6), water distributor (6) is provided with water distribution mouth (11) vertically upward, and water distribution mouth (11) gos deep between adjacent electrolysis of aluminum pole plate (4).
In electrolyzer, both sides are provided with battery lead plate stopper slot (1), are vertically provided with some electrolysis of aluminum pole plates (4), between adjacent electrolysis of aluminum pole plate (4), are provided with micro-electrolysis stuffing (12).The advantage that adopts electrolysis of aluminum pole plate is light weight, convenient lifting, and the sludge quantity of generation is few.If lifting appliance is installed at device top, can be promoted vertically upward electrolysis of aluminum pole plate (4) and go out outside pond to change.
Preferably, micro-electrolysis stuffing comprises carbon dust and iron powder.Between electrolysis of aluminum pole plate, be provided with nonmetal perforation support, be used for filling described micro-electrolysis stuffing.
Effluent trough (3) quantity is 2, is located at respectively tanning dyeing waste water contact break dechromisation treatment unit both sides, is communicated with, and connects water shoot (7) between 2 effluent troughs (3) by effluent trough communicating pipe (5).
Electrolysis of aluminum pole plate (4) is connected with electrolyzer copper bus-bar (2), copper bus-bar (2) its as carrying galvanic main line, make electric current in negative and positive two-stage, cause redox reaction by dyeing waste-water, make to be difficult for by taking off containing chromium complex of alkali precipitation steady, dissociate Cr3+, by alkaline chemical precipitation, process to remove Cr3+, and electrolysis of aluminum pole plate (4) is dissolved in gradually in solution and forms Al3+, need to regularly replace pole plate.
Between adjacent electrolysis of aluminum pole plate (4), keep certain spacing, middle filling can be avoided hardening, the novel micro-electrolysis stuffing (12) of passivation, under acidic conditions, between iron and charcoal, form numerous micro-current response device, the organism in waste water is reduced oxidation under the effect of micro-electric current.When the filler of waste water by iron content and charcoal, iron becomes anode, and carbon becomes negative electrode, and have micro-current flowing, and form numerous small battery, there is electrochemical reaction, the nascent state H+ producing has very high chemically reactive, and the reaction that is difficult to generation under normality is achieved.The ferrous ion producing forms ferric iron through oxidation, in follow-up alkaline chemical precipitation, forms ironic hydroxide, has very high adsorption effect.Electrochemistry synergy due to traditional electrolysis and micro-electrolysis galvanic cell, has obtained better contact break effect, so this device is lower than traditional electrolysis process on power consumption, size is little, and cost is low.Micro-electrolysis stuffing (12) needs periodic replacement.
Dyeing waste-water first, after pre-treatment (grid, precipitation etc.), is adjusted pH value between 5-6 before entering contact break dechromisation treatment unit.Water arrives each water distributor (6) by water inlet pipe (8), then be evenly distributed to water distribution mouth (11) vertically upward, between every group of electrolysis of aluminum pole plate (4), upwards flow out zig-zag water outlet weir notch (10), after converging by effluent trough closed tube (5) between 2 effluent troughs (3), enter water shoot (7) to follow-up alkaline chemical precipitation method processing unit.
When tanning dyeing waste water contact break dechromisation treatment unit bottom settled sludge is more, can open blow-off pipe (9) emptying of bottom.
This installs maximum feature in the advantage that combines micro-electrolysis and electrolytic process, and power consumption is little, is about 1/4th of pure electrolytic process; Treatment effect is good, and the total chromium≤1.0mg/L of water outlet is better than emission standard (total chromium≤1.5mg/L); Require the best pH value of water inlet between 5-6, acid adding amount is few, and medicament expense is about 1/2nd of micro-electrolysis method; Simple in structure, cost is low.This treatment unit also has decolouring in contact break, except COD, reduce the effect of follow-up added amount of chemical.Cleaning, maintenance.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
