Abstract:
A/O process was adopted in a wastewater treatment plant with capacity of 10×104 m3/d in Liaoning Province. The effluent quality of reconstruction project was required to be upgraded from the first level B standard to the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Denitrifying load would be lowered by construction of a new A/O biochemical tank, and nitrogen removal efficiency would be ensured by supplement of carbon source. The inlet water contained a lot of grit which led to serious wear of mechanical equipment such as coarse screen, fine rack and lift pumps. The grit and large particles of floatation in water would be settled by usage of the coarse screen and the horizontal flow grid chamber. As a result, the coarse screen, fine rack and lift pumps would operate normally. Actual operation showed the effluent quality could meet the first level A standard.
