AI Technical Summary

Technical Problem

In existing technologies, traditional purification equipment occupies a large space and has low processing efficiency, making it difficult to quickly handle sudden, high-load overflow sewage or initial rainwater, resulting in the environmental risk of rivers turning black and smelly again being difficult to alleviate.

Method used

An integrated rapid rainwater and sewage treatment device is adopted, including a sewage pipe, an oscillating component, and a reaction pipeline. Through the Venturi effect, spiral blades, oscillating jet, and multi-stage flow channel design, the device achieves automatic addition and efficient mixing of coagulant, extends reaction time, and improves treatment efficiency.

Benefits of technology

It can efficiently treat rainwater and sewage in a short time, reduce the land area required, improve the mixing effect and reaction time of coagulants and sewage, ensure the full settling of solid particles in sewage, and reduce environmental risks.
