HDR反应器处理硫酸庆大霉素厌氧出水

Treatment of anaerobic effluent from gentamicin sulphate production by HDR reactor

以某企业硫酸庆大霉素生产废水的厌氧出水为研究对象,考察高强好氧反应器(HDR反应器)启动运行过程中污泥特性以及对CODCr、NH3-N的去除效果。结果表明:HDR反应器对该废水具有良好的处理效果,CODCr的去除率为70%~80%,NH3-N去除率在95%以上;补磷对CODCr的去除率无明显影响,但可以提高对NH3-N的去除率。

Taking anaerobic effluent from a gentamicin sulphate production company as the research object, the sludge characteristics and removal rates of CODCr and NH3-N in high density aerobic reactor(HDR reactor) during the start-up and operation periods were investigated. The results showed that: HDR had good treatment effect on the said kind of wastewater treatment, the removal rates of CODCr and NH3-N were 70%-80% and above 95% respectively. Although additional phosphorus had little influence on CODCr removal, it could increase the removal rate of NH3-N.
