Advanced sewage treatment method adopting combined use of hydroxyl radical active oxygen-bioactive carbon

Номер: CN0101591129A
Принадлежит:

The invention relates to an advanced sewage treatment method adopting combined use of hydroxyl radical active oxygen-bioactive carbon. The advanced sewage treatment method is characterized in that the method comprises a hydroxyl radical active oxygen treatment unit and a bioactive carbon treatment unit, and comprises the following steps: firstly, sewage to be treated is evenly mixed with hydroxyl radical active oxygen generated by a hydroxyl radical active oxygen generator with the adding quantity between 5 and 25 mg/L; secondly, the sewage enters an oxidizing tower from the bottom of the tower to undergo oxidation reaction therein; thirdly, the detention time inside the oxidizing tower is 5 to 20min till organic contaminants in water are removed, decomposed or converted; and finally, after preliminary treatment, water flows out from the top of the oxidizing tower to enter a bioactive carbon reactor and stays in the reactor for 60 to 180min till the organic contaminants in water are biodegraded ...
