1、摘 要本设计的内容为某造纸厂废水处理工艺设计。造纸厂废水的特点是：所产生的废水悬浮物浓度较高，且有机物浓度也较高。设计中的主要构筑物有格栅、沉砂池、SBR池、絮凝反应器、以及污泥浓缩池。SBR工艺是本次设计的核心。SBR工艺是活性污泥法的变形，由于其具有自动化程度高，抗冲击能力强、池形简单、具有脱氮降磷效果、不产生污泥膨胀等特点，因此SBR处理工艺在小型污水处理设施中应用较广泛。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。本设计需要选择几种造纸厂废水处理的工艺，并对其进行比较，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
