Titanium anode for sewage treatment, ruthenium-iridium titanium anode for sewage treatment

Sewage treatment with titanium anode including domestic sewage, industrial water, factory wastewater treatment process, the electrode not only plays the role of transmitting current, but also plays a catalytic role in the oxidation of organic matter degradation, in this process because it does not cause pollution, known as green water treatment. With the development of industry, organic wastewater discharge is increasing, especially chemical, food, pesticide and pharmaceutical industry discharge of high concentration of wastewater, chroma high toxicity, containing a large number of biodegradable components, serious pollution of the rivers, lakes and seas, electrolysis water treatment technology has no need to add chemicals, equipment small size, small footprint, does not produce secondary pollution, It has been used to treat the wastewater containing hydrocarbon, alcohol, aldehyde, ether, phenol and other organic pollution. COD removal mainly depends on the oxidation reaction on the anode surface, which directly oxidizes and degrades organic matter on the anode surface, so that the organic matter in sewage can be directly or indirectly converted into CO2 and water through electrochemical conversion. The anode potential must be higher than the decomposition potential of organic matter, so the oxidation and oxygen evolution of organic matter are two competitive reactions on the anode.

The noble metal oxide coated titanium anode produced by Shaanxi Zhuohangxin Metal Material Co., Ltd. has higher oxygen evolution overpotential, and the anode potential is higher than the decomposition potential of organic matter.

Suitable for sewage treatment.

The shape of the anode has plate type, tube type, net type and other forms for users to choose, reliable quality. The titanium matrix can be reused.

Application:

Treatment of printing and dyeing wastewater

Disposal of garbage exudate

Treatment of fecal sewage

Treatment of oily wastewater

Treatment of cyanide-containing wastewater from engineering mines

Recovery of metals from wastewater by electrolysis

Hospital sewage treatment

Catering waste water department

Ruthenium-iridium titanium anode is coated with ruthenium-based noble metal compounds on the surface of titanium substrate after special treatment, and is oxidized at high temperature. It can be fully coated or partially coated, and the number of coated times varies from 8-35 times according to the product use requirements. The product surface is black, with uniform coating, solid combination, low chlorine potential, long service life, high current efficiency.

Product shape: net, plate, tube, rod, etc.

1. The anode size is stable, and the electrode spacing does not change during the electrolytic process, so that the electrolytic operation can be carried out under the condition of stable tank voltage.

2. Low working power, small power consumption, consumption can be reduced by about 20%.

3 Titanium anode long working life, diaphragm production of chlorine gas industry, coated titanium anode corrosion resistance to chlorine and alkali.

4. It can overcome the dissolution problem of graphite anode and lead anode, avoid the pollution of electrolyte and cathode products, and improve the quality of products.

5. Can improve the current density. For example, in the production of chlor-alkali by diaphragm method, the current density of the graphite electrode is 8A/dm2, and the titanium anode can be doubled to 17A/dm2, so that the output can be doubled in the electrolytic workshop and electrolytic cell under the same condition.

6. Strong corrosion resistance, can be in many corrosive, have special requirements of electrolytic medium work.

7. Can avoid the lead anode deformation short circuit problem, so as to improve the current efficiency.

8. The matrix titanium material can be used repeatedly.

Application field:

Chlor-alkali, sodium hypochlorite and other industrial production, electrolytic synthesis of organic compounds, sewage treatment, desalination and other used for dilute brine electrolysis with sodium hypochlorite anode, seawater electrolysis with sodium hypochlorite anode, tap water sterilization and disinfection, sewage treatment series electrode products, desalination electrode, eliminate plankton in industrial circulating water.
