摘要:

针对江苏某头孢类抗生素药物生产公司新增头孢唑肟钠项目产生废水的具体水质特点,结合现有污水站情况,将生产中产生的46股废水进行分类收集、分质处理。将高浓含磷废水蒸馏出水、二氯甲烷废水汽提出水混合高浓低盐废水进行微电解-Fenton氧化处理,出水混合高盐废水蒸馏出水、低浓废水和其他产品废水预处理出水,进行厌氧-好氧生化处理,生化出水通过臭氧催化氧化进行深度氧化,各项出水指标均达到园区接管标准。

Abstract:

According to the specific characteristics of water quality characteristics of wastewater generated by a new ceftizoxime sodium project of a cephalosporin antibiotic drug production company in Jiangsu and the existing sewage station condition, 46 types of wastewater originated from production were classified, collected and treated. Distilled water from high-concentration phosphorus-containing wastewater and dichloromethane wastewater were mixed with high-concentration and low-salt wastewater, then the mixed wastewater was treated by micro-electrolysis-Fenton oxidation treatment. The effluent mixed with distilled water of high-salt wastewater, low-concentration wastewater and other product wastewater was treated by anaerobic-aerobic biochemical, and the biochemical effluent was deeply oxidized by ozone catalytic oxidation. All effluent indicators have reached the park takeover standard.

Key words: cephalosporin antibiotic wastewater, biochemical treatment, micro-electrolysis, Fenton oxidation
