**毛纺厂废水处理工程工艺设计
摘 要
本设计题目为“**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：BOD5≦20mg/l，CODcr≦100mg/l，SS≦70mg/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，每座分为八格，处理效果明显。预处理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。

ABSTRACT
The design entitled \a woolen mill wastewater treatment process design,\The works are mainly treated sewage effluent from dyeing and washing lines, washing blankets, embroidery workshop wastewater components. Confirmed by the construction side, the design of handling the largest-scale water daily : 2500 cubic meters per day (including water discharge from the station). Sewage major pollutants CODcr, SS, BOD5, S2-, color, the effluent quality are as follows : dyeing wastewater : CODcr=1495mg/L, BOD5=340mg/L, SS=540mg/L. S2-=1.35-2.16mg/L, pH=3.7-8.62, color 300 times; washing line, washing blankets, embroidery workshop wastewater：CODcr=480mg/L, BOD5=300mg/L. SS=200mg/L, S2-=1.2mg/L, PH=3.7-8.62. color 50 times. The average winter temperature -14.9 ℃, average summer temperature of 29.2 ℃, with the average rainfall 427.1mm. Winter winds led to the northwest, the summer winds led to the southeast. Water Disposal Station : BOD5 ≦ 20mg/l, CODcr ≦ 100mg/l, SS ≦ 70mg/l, PH=6-9, color ≦ 50, the effluent quality in the state's two emission standards.
The design acid hydrolysis Biological oxidation wastewater treatment. Dealing with the main structures regulation pool, pool acid hydrolysis, biological oxidation pond, the vertical flow sedimentation tank, concentrated pool, pumping stations, Dehydration room and the other blower. The main structures of biological oxidation pond used for the traditional contact-oxidation, using a total of two, each divided into eight blocks. significant treatment effect. Pretreatment Regulation pools and pool acid hydrolysis effectively reduce the sewage indicators of biological oxidation pond inundated. Intake provides the best indicator, but also effectively reduce sewage color, plus behind the vertical flow sedimentation tank of flocculation and sedimentation, color indicators greatly reduced. Basically meet water requirements.
Keywords : dyeing wastewater wastewater treatment biological oxidation
