丙烯酸及其酯类生产废水处理工程实例
|
摘要
丙烯酸及其酯类废水具有浓度高、成分复杂、含盐量高、对微生物有毒副作用等特点。山东某污水处理厂采用EGSB和好氧组合工艺处理此类废水。调试运行结果表明,在进水COD为50 000～70 000 mg/L、甲醛为8 000～10 000 mg/L时,污水处理厂出水COD、甲醛浓度可分别控制在300、2 mg/L以内。经过长周期的驯化后,微生物未受到明显抑制,出水水质满足园区污水处理接管标准。
Acrylic acid and its esters production wastewater had the characteristics of high concentration,complex composition,high salt content,microbial toxicity and so on. The combined process of EGSB and aerobic tank was used in a sewage treatment plant in Shandong Province. The results of commissioning and operation showed that the effluent COD and formaldehyde concentrations could be controlled below 300 mg/L and 2 mg/L respectively,when the influent COD and formaldehyde concentrations were 50 000-70 000 mg/L and 8 000-10 000 mg/L respectively. After a long period of domestication,the microorganism was not inhibited obviously,and the effluent water quality indexes met the takeover standards of the sewage treatment plant in the industrial park.
