【摘要】 对涤纶仿丝绸碱减量废水的预处理方法进行了研究。结果表明：采用复合无机盐ＰＣＭ处理碱减量废水，处理效果优于ＦｅＳＯ４、ＰＡＣ、Ａｌ２（ＳＯ４）３；当ｐＨ＝１１～１２，投药量为１０００ｍｇ／Ｌ时，ＣＯＤ去除率可达７５％以上，达到了预处理要求。对ＰＣＭ的主要作用机理也进行了初步探讨。更多还原

【Abstract】 The pretreatment of wastewater from polyes ter fabric peeling for silk like effect has been studied,The experimental results show that the efficiency of inorganic salts compound PCM for alkali peeling wastewater was shown to be superior to FeSO 4、PAC、Al 2(SO 4) 3,When pH Value of wastewater is equal to 11～12,and the amount of PCM used is 1 000 mg/L,over 75% of COD may be removed and the aim of pretreatment can be abtained.The mechanism of PCM has also been investigated.更多还原
