Pilot-scale treatment of pharmaceutical comprehensive wastewater by ABR-CASS fed with different batches of influent

摘要: 采用ABR-CASS耦合工艺在中试反应器中处理某制药厂3批制药综合废水。针对不同进水,ABR和CASS反应器表现出了不同的处理能力。其中,不同成分的3批进水对ABR反应器运行影响不明显。在处理第1批进水的ABR出水时,CASS能够在污泥负荷为0.012 kg/(kg·d)(以MLSS计,全文同)时稳定运行,整个系统对COD的去除率达92.54%,对NH3-N的去除率达95.77%;而在处理第3批进水的ABR出水时,CASS反应器几乎不能耐受该废水。GC-MS的测定结果表明,与第1批进水相比,第3批进水的ABR出水中存在具有毒性的三正丁胺和对甲基苯酚,可能是造成CASS反应器生物系统崩溃的主要原因。为保证ABR-CASS的稳定运行,需重点考察ABR对原水中关键毒害物的去除能力,从而为CASS提供合适的进水条件。Abstract: A pilot-scale anaerobic baffled reactor-cyclic activated sludge system (ABR-CASS) reactor was employed to treat three batches of pharmaceutical wastewater from the same pharmaceutical factory. ABR and CASS showed different treatment capabilities to the wastewater. The ABR was almost hardly affected by the components from different batches of pharmaceutical wastewater. However, the influence to CASS was great. CASS could run stably with sludge loading of 0.012 kg COD/(kg MLSS·d) when fed with the first batch of ABR effluent. For the whole system, the overall efficiencies of COD and NH3-N were 92.54% and 95.77%, separately. However, CASS could not endure the wastewater when fed with the third batch of ABR effluent. GC-MS analysis showed that the toxic compounds of tributylamine and p-methyl phenol from the third batch of ABR effluent might be the main factors caused the crash of CASS. To guarantee stable operation of the whole ABR-CASS system, the elimination capability of ABR on influent key toxic compounds should be concerned to provide suitable influence for CASS operation.
