1、摘 要本设计题目为“宣化某毛纺厂废水处理工程工艺设计”,该工程所处理的污水主要是由染色废水和洗线、洗毯、刺绣车间废水组成。经建设方确认,本设计规模按日最大处理水量:2500 m3/d(包括处理站自用水排水量)。污水主要污染物CODcr、SS、BOD5、S2-、色度等,其污水水质如下:染色废水:CODcr=1495mg/L,BOD5=340mg/L,SS=540mg/L,S2-=1.35-2.16mg/L,PH=3.7-8.62,色度=300倍;洗线、洗毯、刺绣车间废水:CODcr=480mg/L,BOD5=300mg/L,SS=200mg/L,S2-=1.2mg/L,PH=3.7-8.62,色
2、度=50倍。冬季平均温度-14.9 ,夏季平均温度为29.2,年平均降水量427.1mm,冬季主导风向为西北,夏季主导风向为东南。处理站处理水质为:BOD520mg/l,CODcr100mg/l,SS70mg/l,PH=6-9,色度50倍,出水水质符合国家的二级排放标准。本设计采纳水解酸化加生物接触氧化处理废水。处理构筑物主要有调整池、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纳传统的一段式接触氧化,总共采纳两座,每座分为八格,处理效果明显。预处理的调整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,供应了最佳进
3、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,基本上可以满意出水的要求。关键词:印染废水 废水处理 生物接触氧化ABSTRACTThe design entitled Xuanhua a woolen mill wastewater treatment process design, The works are mainly treated sewage effluent from dyeing and washing lines, washing blankets, embroidery workshop wastewater compone
