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、BOD5、SS、NH3-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、BOD5、SS、NH3-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.
Engineering Application of Fenton-ABR Anaerobic-biological Contact Oxidation Combined Process to Treat Chemical Synthesis Pharmaceutical Wastewater
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 meth-od-coagulation sedimentation-activated carbon filtration combined process was introduced in detail.The test results show that the mass concentrations of COD,BOD5,SS and NH3-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,BOD5,SS,and NH3-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 pharma-ceutical 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.
