Wastewater treatment has always been a global problem and is essential for environmental protection and sustainable development. Professional wastewater treatment technology provides an effective way to solve the problem of sewage and wastewater, and several common treatment methods will be introduced below.
1.Biological treatment technology.
Biological treatment technology is a common and effective method of sewage treatment. By using microorganisms in living organisms, organic matter is converted into inorganic substances, thereby degrading and removing pollutants. Common biological treatment technologies include activated sludge method, immobilized biofilm method, and biological filter method.
2.Chemical treatment technology.
Chemical treatment technology is to treat sewage and wastewater by adding chemical agents. Commonly used chemical treatment methods include coagulation, sedimentation, oxidation, and reduction. The purpose of removing pollutants is achieved by chemically reacting with pollutants and converting them into precipitable or oxidizable substances.
3.Physical processing technology.
Physical treatment technology mainly treats sewage and wastewater through physical phenomena and mechanical principles. Common physical treatment methods include filtration, adsorption, membrane separation, and air flotation. By using pores, adsorbent materials, membranes and bubbles of different sizes, pollutants are separated from water, so as to achieve wastewater purification and **.
4.Combined processing technology.
Combined treatment technology is a combination of treatment methods in the process of sewage and wastewater treatment. By treating the sewage sequentially through different treatment units, the pollutants can be better removed and the treatment effect can be improved. Commonly used combination treatment technologies include bio-chemical treatment, bio-physical treatment and chemical-physical treatment.
5.Emerging technologies.
In addition to traditional wastewater treatment technologies, there are some emerging technologies that are being widely researched and applied. For example, photocatalytic technology uses light energy to degrade pollutants into harmless substances; Electrochemical techniques oxidize or reduce pollutants through electrolysis; Biochar technology uses biochar to adsorb and decompose pollutants, etc. These emerging technologies are characterized by high efficiency, energy saving, and environmental protection, and are of great significance for solving the problem of sewage and wastewater.
Wastewater treatment is a complex and environmentally and human health issue. The application of professional sewage treatment technology can effectively solve the problem of sewage and wastewater, and contribute to the realization of sustainable development and environmental protection. Through the continuous exploration and application of biological, chemical, physical and combined processing technologies, as well as emerging technologies, we are confident to meet the challenges of the future and create a cleaner and better environment.
