摘要
本研究的主要依据是以EGSB生物反应器为核心的厌氧工艺处理某厂高温费托合成除油有机废水的试验结果。研究的主要目的是提供一种费托合成高浓有机废水的处理方法。该方法主要是通过在EGSB反应器中接种、驯化普通厌氧颗粒污泥来实现,还要结合废水水质特点,确定一种合理的进水水质组合,使厌氧微生物能够高效、稳定地处理除油后的费托合成高浓有机废水。试验结果表明:EGSB反应器容积负荷为20kg CODcr/(m^3·d),反应器内温度维持在35～37℃,费托合成除油有机废水不加碱中和及EGSB反应器回流比为500%等条件下,系统依然能够正常运行,使有机废水中有机物的去除率高达96%以上,有效降低了企业经营成本。
The main basis of this study is the experimental results from the anaerobic process with EGSB bioreactor as the core to treat the high-temperature Fischer-Tropsch synthesis organic wastewater after degreasing in a plant.The main purpose of the study is to provide a method for the treatment of Fischer-Tropsch synthesis high-concentration organic wastewater.The method is mainly realized by inoculating and domesticating ordinary anaerobic granular sludge in the EGSB reactor.It is also necessary to combine the characteristics of wastewater quality to determine a reasonable combination of influent water quality so that anaerobic microorganisms can efficiently and stably treat Fischer-Tropsch synthesis high-concentration organic wastewater after degreasing.The experimental results indicate that the volume load of EGSB reactor is 20 kgCODcr/(m^3.d),and the inside temperature of the reactor is maintained at 35℃ to 37℃.The system can still operate normally under such conditions that the wastewater is not neutralized with alkali and the reflux ratio of the EGSB reactor is 500%.Thus,96% of the organic matter in the wastewater can be removed.This can reduce the operating costs of enterprises greatly.
