Description
Technical Field

[0002] The STRO sewage treatment device is a device that purifies and treats sewage through physical, chemical and biological treatment. An integrated STRO sewage treatment device usually refers to the integration of various treatment units into one device to save space and simplify the installation and operation process. The integrated STRO sewage treatment device usually has the advantages of compact structure, stable operation, high treatment efficiency, and easy operation. It is suitable for sewage treatment projects of various sizes and types, including industrial wastewater, urban sewage, rural sewage, etc. It plays an important role in reducing pollutant emissions, improving water environment quality, and protecting the ecological environment.
[0003] However, the existing sewage treatment is generally carried out through simple filtration. The sewage treatment cannot remove most of the harmful substances at one time during filtration.

However, only by using a single sedimentation method or filtration method to treat high-concentration sewage, the water quality of the treated water often fails to meet the new emission standards.
