- Abstract:
- The effluent quality from a 35 000 m3/d wastewater treatment plant in Liaocheng City was subject to the first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). In order to further reduce the discharge pollutants, the wastewater treatment plant has been upgraded and reconstructed by adopting magnetic sedimentation technique to meet the level quasi Ⅳcriteria in Environmental Quality Standards for Surface Water (GB 3838-2002), among which the SS limit is 5 mg/L and the TP limit is 0.3 mg/L. This main design parameters of the magnetic sedimentation tank, as well as the improvement measures for the high-efficiency sedimentation tank and equipment were introduced. The original 2 sets of high-efficiency sedimentation tanks and fiber rotary disc filters in the advanced treatment section were replaced by a group of magnetic sedimentation tank which had the same processing capability and stably met the new effluent requirements.
