盐城某制药厂的含甾体激素合成制药废水具有COD高、成分复杂、可生化性差等特点。通过曝气Fe/C微电解-Fenton氧化-混凝的物化工艺对含甾体激素合成制药废水进行预处理研究,考察COD和色度的去除效果,并结合GC-MS分析有机物成分及转化情况。结果表明,改进后预处理各段的COD去除率分别为25.2%、43.1%和18.3%,总去除率为63.6%。废水的NH_3-N和TP有明显降低;色度降至30,B/C上升至0.36,pH偏碱性,为后续生化段提供有利条件;色谱分析表明,预处理对废水中甾体激素的处理能力不强,对酮类和苯胺类有机物去除效果明显。
Yancheng Pharmaceutical Factory containing steroid hormone synthetic pharmaceutical wastewater with high COD, complex composition, poor biodegradability and so on. Through the aeration Fe / C micro-electrolysis-Fenton oxidation-coagulation of the chemical process of synthetic steroid hormone-containing pharmaceutical wastewater pretreatment study to investigate the removal of COD and color, combined with GC-MS analysis of organic matter composition and conversion . The results showed that the COD removal efficiencies of the improved pretreatment stages were 25.2%, 43.1% and 18.3%, respectively, with a total removal efficiency of 63.6%. The NH_3-N and TP of the wastewater decreased obviously; the chroma decreased to 30, the B / C increased to 0.36, the pH was more alkaline, which provided favorable conditions for the subsequent biochemical section. Chromatographic analysis showed that the pretreatment had significant effect on the steroid hormone Processing capacity is not strong, the removal of ketones and aniline organic matter obvious.
