Description

Electrode is apart from adjustable sewage reactor

Technical Field

The utility model relates to the field of sewage treatment equipment, in particular to a sewage reactor with an adjustable electrode distance.

Background

Water is a life source, is a basic substance on which human beings rely to live, and is covered by water in parts of the earth, but the fresh water resources which can be really utilized by human beings are very few. With the rapid development of social economy, the water demand is increased rapidly, and in addition to the waste of water and the pollution of water resources, the lag of sewage treatment facilities and the control of non-point source pollution are insufficient, so that the fresh water resources face two problems of water environmental pollution and water resource shortage. This is increasingly and increasingly more prevalent in some countries and regions, especially in developing countries and regions.

Compared with the shortage of water resources, the method is more urgent to the problem of water resource pollution. The clean water source is one of the basic elements for human survival and social sustainable development, and the problem that natural water resources are polluted by various organic matters is getting worse due to the rapid increase of the discharge amount of waste water caused by the development of human activities and industrial production. Especially wastewater discharged by chemical, pesticide, dye, medicine, food and other industries, has high concentration, large chroma, strong toxicity and complex components, contains a large amount of components which are difficult to be biologically degraded, and brings serious water pollution to the world. Therefore, the treatment, purification and reuse of sewage become important, and if the problem of water resource pollution can be solved well, the shortage of water resources can be relieved to a great extent.

In sewage treatment, the electrochemical flocculation method is also called as an electric flocculation method, namely a soluble electrode (generally an iron electrode or an aluminum electrode) is used as a positive electrode and dissolved in sewage under the action of current to generate hydroxide precipitates of metal ions, and colloidal substances and pollutants in water are aggregated by using the hydroxide precipitates, so that the aim of purifying water quality is fulfilled. The electroflocculation technique involves the reaction of water pollutants with strong electric fields and electrochemically generated oxidation and reduction reactions, which removes heavy metal cations from the water and kills microorganisms in the water, which precipitates charged colloidal matter and removes other ions, colloids, and emulsions significantly. The electric flocculation technology can effectively remove pollutants in water, and is proved by practice, and the electric flocculation technology can be applied to various industrial wastewater treatments, and can be applied to removal of pathogens, heavy metals and pollutants of cleaning water in food production in agriculture and rural areas where the quality of life is emphasized.

In the sewage treatment process, each substance in sewage has different fixed frequency, the current with different frequency is needed to treat the substance, the distance between motors in the existing equipment is fixed, and the frequency cannot be changed under the condition of not changing input voltage, so the type of the treated sewage is less, and the treatment effect is not ideal.
