河南城建学院本科毕业设计摘要 I 摘要本次毕业设计地题目为泌阳县城市污水厂工艺设计, 主要任务是完成该地区地污水厂设计该污水厂地设计规模: 30000 m 3/d, 本工程设计进水水质为: BOD 5=200mg/L, COD=420mg/L,SS=300mg/L,NH 3-N=20mg/L,TN=40mg/L,TP= 根据国家有关规定, 二级城市污水处理厂出水应执行《城镇污水处理厂污染物排放标准》(GB18918-2002 )一级 B 标准则本处理厂出水水质标准为: BOD 5≤20mg/L, COD ≤60mg/L,SS ≤20mg/L,NH 3-N≤8mg/L,PO 4-P≤1mg/L 本文根据其进水水质,水量及出水情况,分析比较 l各种污水处理工艺,确定 l 该污水处理厂采用 A/A/O 工艺,产生地污泥经浓缩,脱水后外运主要设计内容为:污水处理工艺选择及各工艺单元地设计:污泥处理工艺设计:污水处理厂地平面及高程布置关键词:污水处理 A/A/O 工艺构筑物工程设计河南城建学院本科毕业设计 Abstract 河南城建学院本科毕业设计 Abstract II Abstract The graduation design topic for the Miyang sewage treatment plant process design. The main task plete athe region ofthe sewage processing design. Miyang sewage treatment plant the construction scale: 30000 m3/d; The original water: CODCr: 420mg/L, BOD5:200mg/L; SS: 300mg/L; NH3-N: 20mg/L; TN:40mg/L; TP: for handling the water quality toachieve after the country "the urban sewage treatment plant emissions standards (GB18918-2002) level 1Bstandard requirements: CODCrthan60 mg/L, more than 20mg/L BOD5, SSthan 20mg/L, NH3-N than 8mg/L, TPthan mg/L. Inthis paper, according tothe feed water quality, water and water situation, analyses pares the all kinds ofwastewater treatment process, determine the sewage treatment plant using the A/A/O process, the sludge produced bythe enrichment, sinotrans after dehydration. The main design content includes: choosing the wastewater treatment process and the process ofdesign unit ;The sludge treatment process design, (including process flow and the determination ofthe monomer structures design); Sewage treatment plants the plane and elevation layout .
