盐度是浒苔渗沥液和生活污水联合处理的主要限制因素.试验中采用SBR生物处理工艺对浒苔渗沥液和生活污水进行联合处理,并考察了浒苔渗沥液与生活污水混合比例对处理效果的影响.随着浒苔渗沥液投加比例的增加,盐度含量递增,结果表明：①当盐度低于3.2 g/L时,COD处理效果未受显著影响,当盐度高于3.2 g/L时,COD处理效果影响较大;②在高盐度情况下,氨氮处理效果未受显著影响,氨氮去除率维持在90%以上,但从出水硝酸盐氮的含量来看,盐度对反硝化过程存在抑制作用;③磷酸盐处理效果受盐度影响较为显著,磷酸盐去除率持续降低,由85%降至5%;④盐度对活性污泥抑制较为明显,活性污泥浓度由初始的4.1 g/L降至末期的1.9 g/L,污泥形态和结构发生改变.

Salinity is the main factor of affecting enteromorpha leachate and sewage joint treatment.The SBR biological treatment has been employed in the joint treatment of enteromorpha leachate and domestic sewage.Meanwhile,we have investigated the effects of the blending rotios of enteromorpha leachate and sewage on the results of the treatments.Along with the increase of the mixing proportions of enteromorpha leachate,salinity has increased progressively.The result indicates： ①when salinity under 3.2 g/L,COD treatment effect is not significantly influenced,Then when salinity over 3.2 g/L,COD removal rate is remarkably influenced;②under high salinity circumstance,ammonia nitrogen treatment effect is not significantly influenced and the removal efficiency maintains above 90%,but,as seen from the effluent nitrate content,salinity has great effect on denitrifying action;③phosphate removal efficiency is greatly affected,from 85% to 5%;④the activated sludge is obviously inhibited,the activated sludge concentration is lowered from the initial 4.1 g/L to last 1.9 g/L and the sludge shape and structure have changed.
