摘要：

采用“外加磁场+强化混凝+络合除氟”的改良型Fenton工艺对制药园区污水处理厂生化出水进行深度处理中试，重点研究改良型Fenton工艺对有机物、悬浮物、总磷的去除效果，以及耦合络合除氟后对氟化物的协同去除效果。与传统Fenton工艺对比实验结果表明，相同加药量条件下改良型Fenton工艺处理效果更好，而控制相同处理水质条件下，改良型Fenton工艺药剂消耗更少。中试实验结果表明，改良型Fenton工艺运行稳定，对多种污染物协同增效去除效果显著，在中试系统进水COD、SS、TP、F^-平均质量浓度分别为73、15.78、0.47、4.10 mg/L条件下，处理后出水COD、SS、TP、F^-平均质量浓度分别达到33、5.35、0.03、0.80 mg/L，满足山东省地方标准《流域水污染物综合排放标准 第5部分：半岛流域》（DB 37/3416.5—2018）中一级标准要求。对工艺稳定运行后所投加药剂成本进行分析，得到深度处理药剂消耗约为0.51 元/m³。

Abstract:

The improved Fenton process，which was “magnetic field+enhanced coagulation+complexation defluorination”，was used for the pilot study of advanced treatment of biochemical effluent from the sewage plant of a pharmaceutical park. The integrated removal effects of organics，suspended matter，total phosphorous were discussed，as well as the synergic removal effect of fluoride after coupled with complexation defluorination. Compared with the traditional Fenton，the batch experimental results showed that the improved Fenton process had better treatment effect under the condition of the same dosage and had less drug consumption under the condition of controlling the same water quality of the treatment. The pilot test results showed that the improved Fenton process operated efficiently and stably. When the average mass concentrations of COD，SS，TP and F^- of influent were 73，15.78，0.47 and 4.10 mg/L respectively，the outlet average mass concentrations would be 33，5.35，0.03 and 0.80 mg/L，which could meet the requirements of the first level standard of the local standard of Shandong Province“Comprehensive Emission Standards for Water Pollutants in Watersheds—Part 5： Peninsula Watersheds”（DB 37/3416.5—2018）. The cost analysis of the added chemicals after the stable operation of the process showed that the consumption of advanced treatment chemicals was about 0.51 yuan/m³.
