ECSB反应器对制药废水的处理效果研究

Study on Removal Efficiency of ECSB Systems for Pharmaceutical Wastewater

摘要: 目前我国制药行业高速发展，解决制药废水对环境的污染问题已迫在眉睫。微氧技术为微生物创造了独特的氧环境，氧化作用与还原作用同时发生，具有去除效率高、能耗低、剩余污泥量低等优点。本文利用外循环膨胀颗粒污泥床(ECSB)反应器探讨其对制药废水中主要污染物的去除效果。结果表明，ECSB系统去除的主要污染物为有机物，化学需氧量(COD)的平均去除率为95.2%。然而，该系统对氨氮和磷的去除效果并不理想，后续处理工艺可以选择好氧生物处理工艺以及深度处理工艺，最终保证出水的达标排放。

Abstract: At present, the pharmaceutical industry is developing rapidly. It is important to solve the envi-ronmental pollution caused by pharmaceutical wastewater. Micro-Aerobic technology created a special oxygen environment for microorganism. The processes of oxidation and reduction took place at the same time. It has many advantages, such as high removal, low energy consumption, little excess activated sludge. This paper investigated the pollutants removal of pharmaceutical wastewater using Expanded Cycle Sludge Blanket (ECSB) reactor. The results showed that the av-erage COD removal was 95.2%. However, the removal of ammonia and phosphorus was not signif-icant. We need other treatment systems to treat the outflow of ECSB system in order to discharge up to standard.
