Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater membrane treatment, in particular to an electroplating wastewater recycling and application membrane treatment equipment. Background Art

[0002] At present, electroplating wastewater has become an important environmental problem because it contains high concentrations of heavy metal ions and organic matter, which is toxic and carcinogenic, causing serious pollution to water bodies and ecosystems. In order to solve this problem, membrane treatment equipment for recycling electroplating wastewater has been widely studied and applied.

[0003] At the same time, the increasing scarcity of metal resources has also increased the importance of wastewater resource recycling. People's awareness of environmental protection and sustainable resource utilization has gradually increased, which has promoted the research and application of membrane treatment equipment for electroplating wastewater recycling to reduce wastewater discharge and resource waste. As a highly efficient wastewater treatment technology, membrane technology can separate and remove solid particles, suspended matter, heavy metal ions and organic matter in wastewater through the micropores and selective permeability of the membrane. Compared with traditional chemical and physical treatment methods, membrane treatment has the advantages of low energy consumption, small footprint, simple process and easy operation.

[0004] However, the current electroplating wastewater contains high concentrations of heavy metal ions and organic matter, which can easily cause membrane pollution and clogging. The particulate matter and colloidal substances in the wastewater may form a deposition layer on the membrane surface, reducing the membrane flux and treatment effect, and the membrane needs to be cleaned and maintained regularly. Therefore, a membrane treatment equipment for electroplating wastewater recycling application that is easy to clean and maintain the filter membrane is proposed. Utility Model Content
