A PROCESS FOR BIOCHEMICAL TREATMENT OF WASTE WATER USING NANO MATERIALS

摘要

The present invention relates to a process for biochemical treatment of waste water. The process uses a nano material to induce micro to degrade organic pollutants in the waste water which are generally unable or hard to be degraded and thereby greatly enhance the effect of biological cleaning of waste water. The nano material comprises one or more of the group consisting of titania, silicon-based oxide, ferric oxide, zinc oxide, metal iron powder and carbon black. The effect is more prominent for the waste water that is hard to treat by the conventional biochemical treatment, high concentration waste water, and highly poisonous waste water. The process of the present invention is widely usable in the aerobic, oxygen-facultative or anaerobic biochemical treatment systems.
