With the continuous development of industry, the large amount of surface treatment wastewater has become one of the important fields of industrial wastewater treatment. Surface treatment wastewater refers to the wastewater generated in the process of metal surface treatment, which contains a large number of harmful substances such as heavy metal ions, acid and alkali substances, and organic matter. The discharge of these wastewater will not only cause serious pollution to the environment, but also pose a threat to human health. Therefore, how to effectively treat surface treatment wastewater has become one of the urgent problems to be solved in the field of industrial wastewater treatment.
Surface treatment wastewater treatment equipment is a kind of equipment for surface treatment wastewater treatment, and its function is to separate, transform or remove harmful substances in wastewater, so as to achieve the purpose of purification and reuse. Surface treatment wastewater treatment equipment is generally composed of several parts, such as pretreatment, chemical treatment and biological treatment, each of which has its specific role and characteristics.
Pretreatment is the first step in the treatment of surface treatment wastewater, and its main purpose is to remove large particle impurities, oil stains, suspended solids, etc. in the wastewater, and provide good water quality conditions for the subsequent treatment process. Commonly used pretreatment methods include sedimentation, filtration, degreasing, etc. Chemical treatment is the conversion or removal of harmful substances in wastewater through chemical reactions, and commonly used chemical treatment methods include neutralization, precipitation, redox, etc. Biological treatment is the use of microbial metabolism to convert the organic matter in wastewater into harmless substances, commonly used biological treatment methods include activated sludge method, biological filter method, etc.
The design and selection of surface treatment wastewater treatment equipment should be based on the specific situation, and factors such as wastewater, water quality, and discharge standards need to be considered. At the same time, in order to ensure the normal operation of the equipment and the stability of the processing effect, it is also necessary to regularly maintain and maintain the equipment.
2024 Travel Guide In conclusion, surface treatment wastewater treatment equipment is an important part of the field of industrial wastewater treatment and is of great significance for protecting the environment and human health. In the future, with the continuous progress of technology and the continuous expansion of application fields, surface treatment wastewater treatment equipment will be more widely used and developed.
