Novel media-ultra-lightweight sludge ceramics (ULSC) employed in an upflow lab-scale biological aerobic filter (BAF) were investigated for pharmaceutical advanced wastewater treatment. The influences of the volume ratio of pharmaceutical wastewater to domestic wastewater (PW/DW), hydraulic retention time (HRT) and air-liquid ratio (A/L) on chemical oxygen demand (CODCr) and ammonium (NH(4)(+)-N) of the effluent were investigated. When PW/DW of 4:1, HRT of 6 h, and A/L of 5:1 were applied, the mean effluent concentration of NH(4)(+)-N was 6.2 mg L(-1), and the maximum CODCr concentration in the effluent was 96 mg L(-1). Both NH(4)(+)-N and CODCr did not exceed the limits of the national discharge standards (NH(4)(+)-N ≤ 15 mg L(-1), CODCr ≤ 100 mg L(-1)). In addition, the BAF system showed a strong capacity of further removal from NH(4)(+)-N of the effluent.
新型中孔-超轻量污泥陶瓷（ULSC）被应用于上流式实验室规模生物好氧滤池（BAF）中，以处理制药厂的高级废水。考察了制药废水与生活污水的体积比（PW/DW）、水力停留时间（HRT）和气液比（A/L）对出水的化学需氧量（CODCr）和氨氮（NH(4)(+)-N）的影响。当 PW/DW 为 4:1、HRT 为 6 h、A/L 为 5:1 时，NH(4)(+)-N 的平均出水浓度为 6.2 mg L(-1)，出水中的最大 CODCr 浓度为 96 mg L(-1)。NH(4)(+)-N 和 CODCr 均未超过国家排放标准（NH(4)(+)-N ≤ 15 mg L(-1)，CODCr ≤ 100 mg L(-1)）。此外，BAF 系统对出水 NH(4)(+)-N 的进一步去除能力较强。
