Description

The electrocoagulation water treatment device

Technical field

The utility model relates to a kind of device that water is handled, especially a kind of tap water is handled, effectively remove suspended impurity in the water, pigment and heavy metal etc., to satisfy the primary water treatment device of domestic water, big flow process water.

Background technology

In the prior art; The former water of unit for treating water such as electrodialysis, membrane filtration, r-o-and IX technology need carry out prime to be handled; So that can remove suspended substance, pigment, colloid, heavy metal and bacterial micro-organism and partial organic substances in the former water effectively, otherwise will produce detrimentally affect to above-mentioned ion exchange resin, IX and reverse osmosis membrane etc.The former water that uses at present; Its prime treatment unit or adopt water treatment device with high content of technology, that equipment cost is big; Adopt the water treatment weak effect; Can't satisfy and remove materials such as suspended substance, pigment, colloid, heavy metal in the former water, thereby can't guarantee the long-term efficient stable operation of back level water treating equipment.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that prior art exists; And provide a kind of simple in structure; Easy to operate; Can effectively remove materials such as suspended substance in the water, pigment and heavy metal, to help the electrocoagulation water treatment device of the long-term efficient operations of water treating equipment such as back level r-o-, electrodialysis and IX.

The purpose of the utility model is accomplished through following technical scheme; It include one can remove suspended impurity in the water, pigment and heavy metal the electrocoagulation device; Behind the collection surface of said electrocoagulation device, be connected with a floating washing trough, after this floating washing trough, be connected with strainer through a pump.

Described electrocoagulation device is made up of collection surface and negative electrode and the anode by the external rectifier power supply that in collection surface, are provided with at least, and described strainer is a Two-layer filter.

Described RF is a kind of rectifying device of falling the utmost point automatically that can regulate arbitrarily in the scope at 0-30 minutes; Described Two-layer filter is the mechanical type filter that has the washing unit that recoils.

The utility model is city, rural area and field work domestic water refining plant, and it can effectively reduce the turbidity in the water, and makes delivery turbidity less than 1; Can remove in the water heavy metal of harmful human body, and can remove fluorine, reduce pigment, bacterial micro-organism is killed and the filtering effect, have simple in structure, easy to operate, characteristics such as purifying water effect is obvious.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model include one can remove suspended impurity in the water, pigment and heavy metal electrocoagulation device 1; Behind the collection surface of said electrocoagulation device 1, be connected with a floating washing trough 2, after this floating washing trough 2, be connected with strainer 4 through a pump 3.

Electrocoagulation device 1 shown in the figure is made up of with anode 8 collection surface 5 and the negative electrode 7 by 6 power supplies of external RF that in collection surface, is provided with at least, and described strainer 4 is a Two-layer filter.

Described RF 6 is a kind of rectifying device of falling the utmost point automatically that can regulate arbitrarily in the scope at 0-30 minutes; Described Two-layer filter is one to have the mechanical type filter of the washing unit that recoils.

Shown in the figure; The former water of handling 9 gets into collection surface 5 through under meter 10 with nominal flow, flow velocity; Handle RF 6 input dc power fields simultaneously; Water after the processing flows into floating washing trough 2 and further condenses floating washing, and filters with pump 3 input Two-layer filter again, and water outlet after filtering is limpid water purification.

As electrode, after direct supply was connected, anode metal dissolved the utility model with metal aluminum sheet, and metals ion gets in the water, i.e. AI-3e-AI ³⁺Water is by electrolysis H ₂O → H ⁺+ OH ^-

Positively charged hydrogen ion is obtained electronics on negative electrode become hydrogen 2H ⁺+ 2e → H ₂, the hydroxide ion anode that has negative charge in the solution moves, and at anode discharge, i.e. 4OH ^--4e → 2H ₂O ₄+ 2 [0]

After the hydroxide ion discharge, generates new nascent oxygen, at the anode bubble that produces oxygen, in the hydrogen gas bubbles of negative electrode generation; When these bubbles rise, take suspended substance to the water surface, on the water surface, form scum layer; The material that takes the water surface to is many more, and scum layer is just close more thick more, then scum silica frost is removed; Simultaneously pH greater than 3.8 conditions under, AI ³⁺Again with OH ^-Reaction generates AI [OH] deposition, i.e. AI ³⁺+ 30H ^-→ AI [OH] ₃

The white lake that reaction generates generates throw out with the suspended particles in the water, when hour just come-up separation of throw out proportion, when great with regard to precipitate and separate.

The electrocoagulation water treatment can not increase the amount of ions in the water, and alum and tri-chlorination iron rule can cause SO in the water ₄-, the increase of CL-quantity; Electrocoagulation utilizes the anodic oxygenizement, can destroy pigment, organism and killing bacteria mikrobe; Electrocoagulation utilizes the reductive action of negative electrode, and heavy metal precipitation is removed;

The utility model adopts electrocoagulation---filter set assembly system, owing to adopt the contact cohesion, and modern techniquies such as enhancing mixed and Depth Filtration, thus have characteristics such as skinny device, flow, less energy-consumption and effluent quality be excellent greatly.

The utility model is opened earlier electrocoagulation device water intaking valve to the rated flow value in use, treat that the electrocoagulation device is filled water after, drive RF again, boosted voltage progressively is to current rating.After treating that the floating washing trough water of electrocoagulation is full, turn on pump is sent water into Two-layer filter, after device water outlet to be filtered is qualified, and the use of can supplying water.
