摘　　要：采用SBR工艺联合处理浒苔渗滤液和生活污水,并采取逐渐增大浒苔渗滤液与生活污水混合比例[(1∶60)～(1∶0)]的方法来进行试验,待每个比例下的出水稳定后再进入下一比例的试验。结果表明:浒苔渗滤液投量的增加对SBR去除COD和磷酸盐产生较大影响,但对去除氨氮的影响较小;当浒苔渗滤液与生活污水的投加比例约为1∶6时,SBR对COD、氨氮和磷酸盐的去除效果达到最佳,出水COD、氨氮和磷酸盐分别为46、1.8和2.4mg/L;含盐量是影响浒苔渗滤液和生活污水联合处理的主要因素。SBR process was used for joint treatment of Enteromorpha leachate and domestic sew- age, and the method of increasing the mixing proportion of Enteromorpha leachate and domestic sewage gradually was adopted. When the effluent became stable at each proportion, the next proportion experi- ment was conducted. The result indicates that with the increment of Enteromorpha leachate, the removal efficiencies of COD and phosphate are affected greatly, but the removal efficiency of ammonia nitrogen is not affected obviously. When the proportion of Enteromorpha leachate and domestic sewage is 1 ： 6, the optimal removal efficiencies of COD, phosphate and ammonia nitrogen are reached, and their effluent concentrations are 46 rag/L, 1.8 mg/L and 2.4 mg/L respectively. In this experiment, salinity is the main factor of affecting joint treatment of Enteromorpha leachate and sewage.
