Anodic wastewater treatment (anodic oxidation surface treatment system)
1. Anode wastewater treatment
Anode wastewater treatment is an important industrial wastewater treatment technology, mainly applied to wastewater treatment in industries such as batteries, electrolytic copper, electroplating, etc. The basic principle of this technology is to use anodes to oxidize and decompose organic substances in wastewater, converting them into inorganic substances, thereby achieving the goal of purifying water quality.
The anode wastewater treatment technology has the following advantages: firstly, it has good treatment effect and can effectively remove pollutants such as organic matter and COD from the wastewater; Secondly, the equipment is simple, easy to operate, and the maintenance cost is low; The third is that the treatment process does not require the addition of chemical agents, which is safe and environmentally friendly.
However, there are also some drawbacks to anode wastewater treatment technology, mainly including the following aspects: firstly, there is a problem of high energy consumption, which requires a large amount of electrical energy for reaction; Secondly, some harmful substances in wastewater are difficult to remove, such as heavy metals such as chromium and mercury; The third is that certain oxidants will be generated during the treatment process, which may have a certain impact on the environment.
Overall, anode wastewater treatment is an important industrial wastewater treatment technology with certain advantages and limitations. In the future, with the continuous development of technology, we have reason to believe that this technology will continue to improve and innovate, providing better support for achieving a virtuous cycle of industrial production and environmental protection
2. Anodic oxidation surface treatment equipment
Anodizing surface treatment equipment is a common metal surface treatment equipment, mainly suitable for surface treatment of various metal products such as aluminum alloy products and magnesium alloy products. Anodic oxidation surface treatment equipment can form a layer of oxide film on the metal surface, which has excellent properties such as corrosion resistance, wear resistance, insulation, etc. It can not only improve the service life of metal products, but also beautify their appearance and enhance their texture.
The working principle of anodic oxidation surface treatment equipment is to apply electricity in the oxidation solution, using metal products as anodes to cause oxidation reactions on their surfaces, thereby forming an oxide film on the metal surface. This equipment typically includes components such as an oxidation tank, power supply, liquid level controller, temperature sensor, pH controller, etc., which can achieve automated production operations.
At present, anodizing surface treatment equipment has been widely used in the production of metal products in the fields of aviation, automotive, and construction, becoming an important means to improve product quality and extend service life. In the future, anodizing surface treatment equipment will continue to develop, providing more efficient and environmentally friendly solutions for surface treatment of various metal products.
3. Anodic oxidation wastewater treatment process
Anodic oxidation wastewater treatment process is an efficient wastewater treatment technology that can treat various wastewater, including wastewater containing pollutants such as organic matter, heavy metals, and ammonia nitrogen. This wastewater treatment technology uses charged anodes and cathodes to convert pollutants in wastewater into harmless substances through electrochemical reactions. At the same time, the anodic oxidation wastewater treatment process can also simultaneously remove the odor, chromaticity, and turbidity in the wastewater.
In the anodic oxidation wastewater treatment process, the wastewater enters a reaction tank with anodes and cathodes after pre-treatment and initial sedimentation. At this point, the anode undergoes an oxidation reaction, oxidizing the pollutants into harmless substances, while the cathode undergoes a reduction reaction, reducing the useful substances in the wastewater back. The treated wastewater can become safe wastewater after passing through sedimentation tanks and filters, meeting national discharge standards.
Compared to traditional wastewater treatment methods, anodic oxidation wastewater treatment process has advantages such as energy conservation, environmental protection, and high efficiency. At the same time, it can also be applied to wastewater treatment in fields such as electronics, pharmaceuticals, chemicals, and food, making it a very practical technology.
4. Photovoltaic wastewater treatment process flow
The photovoltaic industry is currently one of the fastest growing emerging industries, but the manufacturing process of photovoltaic cells generates a large amount of wastewater, which can have a significant impact on the environment if discharged directly. Therefore, the treatment of photovoltaic wastewater is particularly important.
The photovoltaic wastewater treatment process is divided into three stages: pre-treatment, biological treatment, and advanced treatment. Pre treatment mainly involves removing impurities such as solid particles and oil from wastewater, usually using flat sedimentation tanks and air flotation tanks for treatment. The biological treatment adopts aerobic biological method, which decomposes and degrades the organic substances in photovoltaic wastewater through aerobic bacteria, converting them into inorganic substances and releasing CO2 and H2O. Advanced oxidation technology is used for advanced treatment to degrade residual substances that are difficult to decompose in wastewater into CO2 and H2O.
In summary, the photovoltaic wastewater treatment process can effectively degrade the organic substances in photovoltaic wastewater, reduce environmental pollution, and promote the sustainable development of the photovoltaic industry.

Dissolved air flotation with Lamella system
Purpose:
Dissolved air flotation machine is a kind of solid-liquid separation equipment commonly used in sewage treatment industry. It can effectively remove suspended solids, grease and gum substances in sewage. It is the main equipment for sewage pre-treatment. Dissolved air flotation machine is widely used in petroleum, chemical industry, printing and dyeing, papermaking, oil refining, leather, steel, mechanical processing, starch, food and other sewage treatment.
working principle
FLQF combined air flotation tank is composed of air flotation tank body, dissolved air system, dissolved air return pipeline, dissolved air water release device, slag scraping device (combined type, traveling type and chain plate type can be adopted respectively according to the needs of users) and electric control cabinet. Air floatation separation technology refers to that air and water under a certain working pressure make the gas melt into the water to a large extent, strive to be in a saturated state, and then release the formed pressure dissolved air and water through decompression to produce a large number of micro bubbles, fully contact with the suspended flocs in the water, make the suspended flocs in the water adhere to the micro bubbles, and float to the water surface with the bubbles to form scum and scrape off the scum, so as to purify the water quality.
Single processing capacity: 1 ~ 100m3 / h Type: partial reflux dissolved air flotation High efficiency air dissolving system provides high-quality air dissolving water with large amount of bubbles and small diameter Select different reflux ratio according to different raw water quality to ensure the removal rate Stainless steel chain type foam scraper has good reliability, and the number of scrapers can be increased or decreased to adapt to different sludge volumes In order to reduce land occupation and cost, coagulation reaction tank, clean water tank and other process equipment can be selected for joint construction The control equipment with the electromechanical control cabinet operates fully automatically according to the setting mode Optional materials: carbon steel epoxy anticorrosion, carbon steel lined with FRP, stainless steel SS304
