摘 要
本设计的题目是祥云镇污水处理厂工艺设计，处理污水主要为城市生活用水，主要任务是工艺流程选择及构筑物设计和计算。
其中初步设计要完成设计说明书一份，污水处理厂高程图一张，平面图一张，调节池图一张，氧化沟一张，二沉池一张，污泥浓缩池图一张。
该污水处理厂工程，总规模达到1400吨/日，该污水处理流程为：从进水管进入调节池，再经过厌氧池脱磷后进入氧化沟，二沉池，最后出水：污泥的流程为：从二沉池排出的剩余污泥首先进入浓缩池，进行污泥浓缩，然后进入污泥脱水车间进一步脱水后，运出厂外。
进水水质城市污水水质如下：BOD5 100 ~210mg/L, CODcr 200~350 mg/L，SS 150~250mg/L，NH4-N 14.6~24.8mg/L，TN 40.5~45.2 mg/L磷酸盐 3.0~6.2 mg/L，pH 6.5~8.2 mg/L，水温 10~30 ℃。出水执行《城镇污水处理厂污染物排放标准》（GB18918-2002）中的一级B标准排放的要求，出水水质要达到如下标准：BOD5 20mg/L, CODcr 60 mg/L，SS 20mg/L，NH4-N 15mg/L，TN 20mg/L ，TP 1 mg/L，pH 6~9 mg/L，水温 10~30 ℃。。

Abstract
Abstract this graduation project’s topic is the sanitary sewage treatment plant technologic design of xiangyun county . The primary mission is the technical process choice and the construction and the computation.
And the preliminary design must complete design instruction booklet one, Sewage treatment plant flow chart, aeration sand collector chart, oxidation ditch chart, two sink pond chart.
The sewage treatment plant project, total dimensions to achieve 1400tons / day, This sewage factory’s sewage treatment flow is: From the water inlet pipe into the regulation pool, through the anaerobic pool dephosphorization in oxidation ditch, two sedimentation tank, the final effluent: sludge process: two from the settling tank sludge discharged into the first concentrated tank, sludge thickening, and then enter the sludge dewatering workshop further dehydration, carry out.
Influent quality of city sewage water as follows: BOD5 100 ~210mg/L, CODcr 200~350 mg/L，SS 150~250mg/L，NH4-N 14.6~24.8mg/L，TN 40.5~45.2 mg/L,TP 3.0~6.2 mg/L，pH 6.5~8.2 mg/L，the temperature of the water is 10~30 ℃。Implementation of\standard\(GB18918-2002) of an B standard emission requirements. Water quality to achieve the following standards：BOD5 20mg/L, CODcr 60 mg/L，SS 20mg/L，NH4-N 15mg/L，TN 20mg/L ，TP 1 mg/L，pH 6~9 mg/L，the temperature of the water is 10~30 ℃。
