METHOD AND APPARATUS FOR PREVENTING AND CONTROLLING CONTAMINANTS FOR RECLAIMED WATER REUSE IN SEVERE WATER SHORTAGE AGRICULTURAL ACTIVITY REGION

摘要

An apparatus for preventing and controlling contaminants for reclaimed water reuse in a severe water shortage agricultural activity region, comprising: an A ²/O tank (1), a nanometer aeration tank (2), and a quick soil permeation device (3) which are sequentially connected, waste water to be treated being introduced into the A ²/O tank (1), the waste water being sequentially treated in an anaerobic environment, an anoxic environment, and an aerobic environment, the supernatant of the treated waste water being transferred into the nanometer aeration tank (2), and the supernatant of the waste water which has been treated by the nanometer aeration tank (2) being introduced into the quick soil permeation device (3) and flowing through one or more layers of filler laid in the quick soil permeation device (3), so that contaminants are degraded or removed. Further disclosed is a method for preventing and controlling contaminants for reclaimed water reuse in a severe water shortage agricultural activity region.
