ICX厌氧反应器启动及处理高浓度工业废水的研究
|
摘要
随着废水排放标准的不断提高,高浓度工业废水(比如化工、啤酒、造纸等的处理要求越来越高,一般高浓度工业废水进入废水处理系统的COD浓度量已经超过10000mg/L,同时钙离子、铁离子浓度和硫酸根浓度也很高,传统的IC易形成污泥钙化,去除效率不稳定等问题。新的ICX改良了内部布水结构和泥水气三相分离器的构造,容积负荷提高,气密性高,无废气产生,更加适用于新形式下的高浓度工业废水处理。本次研究了ICX反应器的启动过程和ICX反应器在高浓度工业废水中的容积负荷、钙离子截留情况。。
More requirements are increasingly proposed on the treatment of high concentration industrial wastewater(such as from chemical, beer and paper making industry) in response to the continuously upgrading boundaries set by wastewater discharge standards. Generally, the high concentration industrial wastewater entering into wastewater treatment system already has a high COD concentration level over 10000 mg/L with calcium ion, ferric ion and sulfate radical concentration equally high. Vulnerable to sludge calcification, traditional IC has some disadvantages such as unstable removal efficiency. The new ICX reactor is more applicable for high concentration industrial wastewater treatment in the new era with improved interior water distribution structure and sludge-water-gas separator structure, increased volumetric loading and zero exhaust gas emission. The paper investigated into the startup process of ICS reactor, and the volumetric loading and calcium ion rejection degree displayed by ICS reactor when treating high concentration industrial wastewater.
