摘　　要：对生物制药废水水解酸化反应器采用接种污泥的方式进行启动,在不断增加进水污染负荷的条件下,40 d内完成水解酸化反应器的启动。试验研究表明:当水解酸化反应器的水力停留时间为8h时,COD去除率可达到34.2%。而且,水中有机氮在水解酸化过程中转化为氨氮,为后续二级生物处理提供了高效去除氨氮的基础。The biological pharmaceutical wastewater is pretreated in a hydrolysis acidification and it is started by the sludge inoculation method. Under condition of increasing water pollution load,hydrolysis acidification reactor has completed in 40 days. Experimental study shows that： when the HRT of hydrolysis acidification reactor hydraulic is 8h,removal rate of COD can reach 34. 2%; organic nitrogen in the water is converted to ammonia nitrogen in the hydrolysis acidification process and it will provide foundation of the efficient removal of ammonia nitrogen for the secondary biological treatment.
