摘　　要：以某制药工业园区污水处理厂的废水为例,将其极低可生化性(BOD_5/CODcr<0.1)的进水进行芬顿氧化法预处理,以期提高其可生化性,相应降解有机物。通过多次、多参数试验,选择Fe SO_(4)·7H_2O投加量0.745 mg/L、双氧水(30%)投加量0.45 m L/L、反应时间2 h,可生化性提高到0.187,CODcr去除效果最佳能达到35%,有利于下一步的生化处理。Taking the wastewater of a sewage treatment plant in a pharmaceutical industrial park as an example,the influent water with very low biochemical availability(BOD5/CODcr<0.1)was pretreated by Fenton oxidation to improve its biochemistry and degrade organic matter accordingly.Through multiple multi-parameter tests,it was determined that when FeSO_(4)·7H_(2)O dosage was 0.745 mg/L,hydrogen peroxide(30%)dosage was 0.45 mL/L,and the reaction time was 2 h,the biochemistry was increased to 0.187,and the CODcr removal effect could reach 35%,which was conducive to the next biochemical treatment.
