Advanced purification system for sewage using a fishway with contact oxidation bank

摘要

[Purpose] If clean sewage is discharged into clean rivers, clean rivers will be contaminated. For this reason, it is going to refine | purify discharged sewage highly by the advanced purification apparatus of the sewage using the fishway by a contact oxidation bank. [Composition] Disposed sewage and mixed water weirs are arranged on both sides of the upstream and downstream ends of the contact oxidation levee with multi-gap provided continuously in the longitudinal direction of the river water mixed with the discharged sewage. By alternately moving movable weirs, a large amount of discharged sewage is permeated and purified, and sometimes this device is arranged in columns or rows, and repeated operation prevents clogging and maintains high water quality. [Effect] Equipment that purifies sewage drainage using natural energy, eliminating the running costs required for water treatment, and sludge from water treatment is treated in the natural ecological cycle and discharged. Oil and sludge are also purified and the seafood becomes delicious.
