摘　　要：对胶体多、偏碱性的原水 ,通过投加 PBACF能有效地降低 SDI和 p H值。同时发现为保护 CA膜投加的余氯能完全透过膜 ,在其浓度为 0 .4～ 0 .5 mg/L时 ,会导致后处理混床中 2 0 1× 7型阴树脂 (或杂质 )The SDI and pH values of the raw water with quite a few of colloids an week basicity can be effectively decreased by dosing PBACF, and in the course of reverse osmosis(RO) for preparing pure water, it can be found that the residual chlorine, which was dosed to protect the RO membrane, can fully permeate through the RO membrane; when concentration is within 0.5-5.0 mg/L, it can lead to oxidation and decomposition of 201×7 type anion resigns(or impurities) in the mixed bed of post-treatment.
