Abstract
PURPOSE: To make the recycling pump unnecessary, and to improve the rate of denitrification, by installing the recycling pass for forcibly transporting the content liquid of the denitrification tank to the nitrification tank using the airlift device, and the return pass from the nitrification tank to the denitrification tank.
CONSTITUTION: The denitrification tank 1 provided with the raw water inlet 6 and the nitrification tank 2 provided with the treated water outlet 7 are connected by the communicating pass 3. The airlift device 13 is arranged inside or outside the denitrification tank 1 or the nitrification tank 2, on purpose to forcibly transport the content liquid of the denitrification tank 1 into the nitrification tank 2. Besides, the content liquid of the nitrification tank 2 is recycled through the recycling pass 5 by means of natural or forced falling method. According to this mechanism, the operational management is made easy, the energy saving can be contrived, and also, the treated water of good quality can be obtained.
