摘　　要：对P-RC APMP制浆系统非过程元素的积累进行了研究和核算,并分析了制浆废液蒸发器垢层的形成及成分。结果表明,系统中非过程元素按积累量由大到小的顺序排列为Si、Ca、K、Cl、Mg、S、P、Fe、Mn、Al;蒸发器垢层主要以Ca、Si、P、Mg元素为主,其中钙镁垢与硅垢各占近30%;垢层的防控需要从对系统中非过程元素的监控做起。The study and calculation of non-process elements accumulation in P-RC APMP process were carried out,and the formation and component of scale in evaporator which is used for concentrating the pulping waste liquor were analyzed.The results showed that the order of accumulation amount of non-process elements from high to low was Si,Ca,K,Cl,Mg,S,P,Fe,Mn,Al,in which,Si and Ca/Mg salts accounted for nearly 30％ separately.The amount of non-process elements should be controlled in order to slow down the formation of the evaporator scale.
