State Environmental Protection Engineering Centerfor Organic Chemical Industrial Wastewater Disposal and Resource Reuse. Nanjing, Jiangsu 210046 , China) Abstract： The wastewater produced by a pharmaceutical raw material enterprise has high COD, high organic phosphorus and complex components. The physicochemical pretreatment process of % micro-electrolysis + second-order Fenton + Ozonation” and the biochemical treatment process of % hydrolytic acidification + A/o” were desicned. The en/ineerin/ practice shows tiat the total phosphorus removat rate is over 80% after physical and chemicat pretreatment, and the total phosphorus can be reduced to less than 5 m/oaiteobcoahemcaa toeatment. Key words： Highty concentrated organic phosphorus wastewateo； refractory t biodegradation； physicochemical process; nitro- /en and phosphorus remove. 1工程概况 表 1废水水质、水量 某原料药企业在生产过程中排放的废水,成分 水量 COD 总磷 总盐 pH 复杂、生物毒性大、盐分高、残留的有机溶剂多，属
