Industrial Wastewater Treatment with Decanter Centrifuges

With the rapid development of the social economy, the centrifuge industry has also experienced rapid development. In responding to the increasing environmental pollution and the impact on chemical production processes, the decanter separator plays a significant role in industrial wastewater treatment. Harmful substances that are increasingly common and serious, especially in the organic production processes of fine chemical products (such as medicine, dyes, cosmetics, etc.), are complex in structure, and anti-corrosive agents that degrade toxic and harmful biological materials. Therefore, the difficulty of treating chemical plant wastewater is relatively high.

The Treatment methods of chemical wastewater by decanter separator

Technology enterprises have been developing wastewater treatment methods for over 100 years. The types of pollutants in wastewater and the amount of wastewater continuously increase with the rapid development of socialist economy and the improvement of living standards. The wastewater treatment system technology of the decanter separator has undergone significant changes along with the development of scientific management technology. At the same time, the old wastewater treatment-related technologies are constantly being upgraded and improved. In particular, there are a wide variety of pollutants in chemical wastewater, and a single process cannot remove all pollutants in wastewater. The great difficulty and high operating costs of physical, chemical and chemical wastewater treatment technologies in meeting emission standards are challenging. Biochemical technology is not always effective since the wastewater often contains a large amount of difficult-to-degrade organic matter with poor biodegradability.

In response to the development characteristics of wastewater treatment in chemical plants, proper pre-treatment research methods, such as flocculation, internal electrolysis, electrolysis, adsorption, and degradation of difficultly-degradable organic matter in wastewater, and improvement of the biodegradability of wastewater should be adopted according to the quality of the wastewater from actual student lifestyles by the decanter separator. Then, biochemical analysis methods, such as SBR, contact oxidation technology, A/O process, etc., are used for teaching in-depth information processing for chemical wastewater.

Currently, various combined technologies are also often used for the treatment of chemical wastewater. For example, the wastewater from pharmaceutical companies is treated by internal electric coagulation sedimentation-anaerobic-aerobic processes. Organic chemical production wastewater is treated by large pore adsorption resin adsorption and anaerobic-aerobic biological technology. The wastewater from ephedrine is treated by flocculation-electric baiting method. Different ozone-biological activated carbon processes are used to remove organic combined pollutants in water. The combination management method of photocatalytic oxidation-internal electrolysis and the treatment of highly concentrated industrial wastewater have achieved relatively good results. The composition of chemical wastewater is complex, and the quality and quantity of water are highly variable. It is difficult to obtain good treatment results because their compliance requirements become more stringent. Various combination treatment technologies are adopted for chemical wastewater treatment according to the actual development situation of students.

The Significant Role of the decanter separator in Chemical Wastewater

Various wastewater treatment methods have been developed based on the characteristics of different pollutants, especially for the treatment of chemical wastewater, which includes physical and chemical methods. Therefore, the role of the decanter separator in industrial chemical wastewater treatment is also significant. We also need to continuously upgrade and improve our technology to treat wastewater better.
