摘要
废水生物处理中,为了使好氧生物能够更好的去除废水中的有机污染物,废水进入好氧生物处理前的可生化性(BOD5/CODcr值)是关键所在。为了提高废水的可生化性,目前水解酸化、臭氧氧化和芬顿法是最常用的三种方法。由于这三种方法的作用原理、影响因素、应用条件、投资成本等多不相同,通过初步分析总结出三种方法的适用条件和初步结论。
In order for aerobic organisms to better remove the organic pollutants in biological treatment of wastewater,biodegradability(BOD5/CODcr) before entering the aerobic biological treatment of waste water is the key.In order to improve the biodegradability of wastewater,hydrolysis acidification,ozoneoxidation and Fenton are the three most commonly used methods.Since the action principles,influencing factors,conditions of application,investment costs of these three methods are not the same,the paper summarizes the conditions for the application of these three methods through preliminary analysis and arrives at preliminary conclusions.
