- Abstract:
- The current scale of a wastewater treatment plant in Wuhu City is 10×104 m3/d, and its effluent quality was required to meet the first level A limit specified in the discharge standard. In the phase Ⅱ project, the total scale of the wastewater treatment plant was expanded to 20×104 m3/d, and the effluent quality was upgraded to the quasi class Ⅳ limit specified in the surface water standard. The process consisting of modified Bardenpho biological reactor, magnetic coagulation high efficiency sedimentation tank and denitrification deep bed filter was adopted in the phase Ⅱ expansion project. The potential of the existing multi-mode AAO reactor in the phase Ⅰ project was tapped through adding suspended carriers, so as to enhance the nitrification and denitrification performance. Actual operation showed that the effluent quality met the discharge standard stably. The total investment of the project was 397.374 7 million yuan, and the unit operating cost was increased by 1.47 yuan/m3.
