采用SBR法处理高盐肝素钠生产废水，探讨了曝气时间、进水pH、温度等参数对COD和氨氮降解效果及污泥生长的影响。结果表明，控制曝气时间为10 h、进水pH为7．5、反应温度在26～29℃时，COD和氨氮去除率均能稳定在85％以上；对氨氮去除效果较差的反应器，适当添加K＋、Ca2＋、Mg2＋可以取得一定的改善作用，其中K＋对Na＋和NH4＋双重毒性抑制的拮抗效应最明显；经参数优化后的SBR反应器对不同污泥负荷和盐度负荷具有较好的适应能力，受到冲击后COD和氨氮去除率均能在2～3个运行周期内恢复至90％以上。

High salt heparin sodium production wastewater is treated by sequencing batch reactor (SBR) .The effects of aeration time ,water pH ,temperature on the COD and ammonia biodegradation and sludge growth are investigated .Results indicate that ,COD and ammonia removal rate can stabilize at more than 85% when the aeration time is 10 h ,water pH 7 .5 and temperature 26 to 29℃ .Adding K+ ,Ca2+ ,Mg2+ appropriately can get some improvement for ammonia removal in less ef-fective reactor ,in which the antagonistic effect of K+ on dual-toxic inhibition of Na+ and NH4+ is most obvious .At opti-mum conditions ,SBR reactor has better adaptability for different sludge and salinity loadings and COD and ammonia removal rates both can recover to more than 90% within running 2~3 cycles after the loading shock .
