Abstract:

The wastewater from pharmacy production has been treated in depth by the combined process,coagulation-biochemical treatment-RO(reverse osmosis)-triple effect evaporator. Part of organic matter,nitrogen and phosphorus can be removed by coagulation precipitation and biochemical treatment. Then,the residual organic matter,phosphorus,nitrogen and salinity can be removed by the RO System. At the end,the RO system concentrated water can be evaporated and concentrated by the triple-effect evaporator. The result shows that the effluent quality can meet the water quality requirements for enterprise production technologies and reach the goal of zero discharge.

Key words: wastewater from pharmacy production, coagulation precipitation, biological process, reuse, zero disch-charge

摘要：

采用混凝、生化、反渗透（RO）和三效蒸发器组合工艺，对某制药企业生产废水进行深度处理。通过混凝沉淀、生化处理去除部分有机物和氮磷，然后利用RO系统去除剩余的有机物、氮磷和盐分，最后采用三效蒸发器对RO系统浓水进行蒸发浓缩。研究结果表明，出水水质可满足企业生产工艺用水水质要求，并达到零排放的目的。
