3、点是：污水中的COD、悬浮物（SS）含量高，色度严重。设计中的主要构筑物有格栅、沉砂池、SBR池、絮凝反应器、接触消毒池以及污泥浓缩池。SBR工艺是本次设计的核心。SBR工艺通过程序化控制进水、反应、沉淀、排水和闲置五个阶段，来完成对废水的生化处理。经过该工艺处理后的出水水质达到造纸废水排放标准GB35442001一级排放标准。本设计需要比较几种工艺，根据处理污水量和其他要求确定造纸厂废水处理工艺并确定废水处理工艺流程图；并对各种构筑物进行了详细的设计计算，同时也对废水处理工艺进行了工程预算。关键词: 造纸废水，SBR工艺，设计 ABSTRACTThe content of paper mil
