温度对“SH-A”工艺处理阿托伐他汀钙制药废水的影响研究

Study on the Influence of Temperature on the “SH-A” Process of Atorvastatin Calcium Pharmaceutical Wastewater

摘要: 本文采用SH-A工艺对处理阿托伐他汀钙制药废水的效果进行了研究，重点研究了温度对SH-A工艺处理阿托伐他汀钙制药废水的影响。实验结果显示：采用SH-A工艺处理阿托伐他汀钙制药废水，能够有效去除废水中的COD和-N；温度对SH-A工艺处理阿托伐他汀钙制药废水具有较大的影响。在给定条件下，对于COD，随着系统温度的升高，COD的去除率明显提高，当温度达到35℃，COD去除率达到最大值，继续升高温度，COD去除率有所降低；对于NH4+-N，随着系统温度的升高，其去除率亦明显提高，当温度达到29℃，-N去除率达到100%，继续升高温度，去除率保持不变。根据实验结果，应选择35℃作为本工艺处理阿托伐他汀钙制药废水的最佳温度。 In this paper, the effect of using SH-A process to treat Atorvastatin Calcium pharmaceutical wastewater is studied. This study mainly focuses on the effect of temperature on the SH-A process. The experimental results show that: the SH-A process has an effective removal of COD and -N; temperature is key factor of the treatment effects. Under the given conditions, the COD removal efficiency improved significantly with the increasing system temperature; the maximum COD removal rate occurred when the temperature reached 35˚C; continued to rise system temperature, COD removal rate decreased. In terms of the -N, with the increase of the system temperature, the removal rate was significantly improved; when the temperature reached 29˚C, -N removal rate reached 100%; continued to rise the temperature, the removal rate remained unchanged. According to the experimental results, the optimal tempera- ture for SH-A process to treat the Atorvastatin Calcium pharmaceutical wastewater should be 35˚C.
