摘　　要：化学合成制药废水具有有机物浓度高且成分复杂的特点,通过研究废水特征,探索一种高效稳定的处理工艺。以某工程为例,采用芬顿氧化-ABR厌氧-生物接触氧化法-混凝沉淀-活性炭过滤组合工艺,对工艺进行了详细介绍。化验结果显示,废水COD、BOD_(5)、SS、NH_(3)-N的质量浓度分别为5200~5400 mg·L^(-1)、1100~1250 mg·L^(-1)、180~200 mg·L^(-1)、50~60 mg·L^(-1)、色度为80~100度。经105 d系统调试,不断优化运行控制参数,出水COD、BOD_(5)、SS、NH_(3)-N的质量浓度分别达到180 mg·L^(-1)、30 mg·L^(-1)、10 mg·L^(-1)、20 mg·L^(-1)以下,色度达到10度以下,主要污染物指标可达到《化学合成类制药工业水污染物间接排放标准》(DB41/756—2012)中的B级标准。针对此类化学合成制药废水,采用芬顿-ABR厌氧-生物接触氧化法组合工艺,技术可行,具有良好的环境效益。Chemical synthesis pharmaceutical wastewater has the characteristics of high organic matter concentration and complex organic matter components,by studying the characteristics of wastewater,an efficient and stable treatment process is explored.Taking a certain project as an example,the Fenton oxidation-ABR anaerobic-biological contact oxidation method-coagulation sedimentation-activated carbon filtration combined process was introduced in detail.The test results show that the mass concentrations of COD,BOD_(5),SS and NH_(3)-N in the wastewater are 5200~5400 mg·L^(-1),1100~1250 mg·L^(-1),180~200 mg·L^(-1),50~60 mg·L^(-1)and the chroma is 80~100 degrees.After 105 d of system debugging and continuous optimization of operation control parameters,the mass concentrations of COD,BOD_(5),SS,and NH_(3)-N in the effluent should reach below 180 mg·L^(-1),30 mg·L^(-1),10 mg·L^(-1),and 20 mg·L^(-1)respectively,and the chromaticity should reach below 10 degrees and the main pollutant indicators can reach the Indirect discharge standard of water pollutants for pharmaceutical industry Chemical synthesis products category(DB41/756—2012)Table 1 Class B standard.For this type of chemically synthesized pharmaceutical wastewater,the Fenton-ABR anaerobic-biological contact oxidation method combined process is technically feasible and has good environmental benefits.
