摘要： 针对焦化废水可生化性差、难以生化处理的特点，采用微电解工艺作为预处理措施，去除部分污染物并提高废水的可生化性，再利用SBR活性污泥法进行了深度处理实验. 结果表明，微电解法不仅能去除焦化废水中的COD、酚、氰、硫化物等有机污染物(COD去除率为70%, 酚、氰、硫化物去除率分别为76.8%, 65.9%, 70.3%)，而且还能提高废水的可生化性(BOD5CODcr由处理前的0.28提高到处理后的0.54，可生化性提高了48.2%). 通过正交试验确定了微电解法预处理焦化废水的适宜参数为：进水COD22002400 mgL，进水pH值约3.03.2，微电解水力停留时间HRT5565 min，FeC(体积比)11.5. 应用微电解预处理SBR深度处理焦化废水，可使出水达标排放(国家I级排放标准GB1345692).

Abstract: Challenges and opportunities to antibiotics are reviewed. Antibiotics, which have greatly enhanced human health, now are facing the issue of drug resistance of pathogen microbes and newly found diseases. However, modern biotechnology, including genomics, proteomics, bioinformatics and bio-macromolecular crystallization, is providing new ideas and methodology for the research and development of new pharmaceuticals.
