1、印染废水处理工艺环境工程等专业毕业设计毕业论文I摘要废水处理厂设计规模2000m3/d设计水质水量为Q=2000m3/d,BOD5=230mg/LCODcr=1100mg/LPH=911SS=210㎎/l,色度400倍。经处理后应达到下列出水水质BOD≤25mg/L,COD≤100mg/L色度≤40倍SS≤70mg/L,PH=69。本设计采用水解酸化加生物接触氧化处理废水。处理构筑物主要有调节池、水解酸化池、生物接触氧化池、竖流式沉淀池、浓缩池、泵房、脱水机房和鼓风机房等。其主要构筑物生物接触氧化池采用传统的一段式接触氧化总共采用两座每座分为四格处理效果明显。预处理

2、的调节池和水解酸化池有效的降低了污水的各项指标为生物接触氧化池的进水提供了最佳进水指标同时还有效的降低了污水的色度再加上后面的竖流式沉淀池的絮凝沉淀作用色度指标大大降低基本上可以满足出水的要求。关键词印染废水废水处理生物接触氧化www.docin.comIIAbstractThedesigningscaleofwastewatertreatmentplantis2000m3/d,thedesigningqualityandquantityofwaterare:Q=2000m3/dBOD5=230mg/L,CODcr=1100mg/L,PH=911,SS=210㎎/l,Colo
