This plant lies in the suburb of some district. It can dispose 36,000 cube sewage every day. The primary concentration of BOD5 and SS is400mg/L and350 mg/ L.The process of this thesis is manmade wetland treatment system, which is a new pathway in the sewage treatment. The technique of this process is offer parative advantages in economic and technology. The quality of disposed effluent is up to the second class of national standard.The first step of this process is screening, which removes bigsized trash. Then the minuting device mutate and shred the solids in the sewage and the waste flow into the primary setting tank through the mesh grid，The sewage go throughthe thin grill to the initial sinking pond, at this step the solid suspension which may precipitate in the sewage are removed . According to request and this craft characteristic which designs needed, take the spoke to flow the type sedimentation the sewage enters tires of the oxygen pond, may absorb removes part of anic matters, and releases the massive phosphorus. The interior design of the tires of the oxygen pond is the the sewage enters the oxygen pond,the anic matter in the waste water are degraded by the good oxygen, simultaneously the sludge massively will absorb the phosphorus in the waste water. Responded the pond design for pushspread the type rectangle response pond, the design specification is the same as the initially sinking the . . . . .學習參考 sink the dirty mire of the pond was passed by dirty mire in surplus in empress in pump house in reflux the dirty mire pump beats in to lack to keep the pond , at which the BOD5 and SS of the waste are up to the national standard, Because less sludge was made during this process of treatment, so after concentrator they can be transport out of the plant.This thesis use reliably safety precautions, reasonable arranges and beautiful surroundings. The sewage treatment plant could be build like a garden.Key words: hate the kind pond, Like to keep the pond, The A/the living creature of O divided by the system of P. . . . .學習參考目 錄前言 ....................................................................1第一章 概述 .............................................................3 現狀分析 ..........................................................3 污水處理工藝方案比較 ..............................................4 AB 法 ..........................................................4 SBR 法 .........................................................4 A/O 法 .........................................................5 A/A/O 法 .......................................................5 傳統活性污泥法 ................................................5 工藝確定 .......................................................6第二章 任務及工程概況 ...................................................7 設計任務及范圍 ....................................................7 設計任務 ......................................................7 設計范圍 ......................................................7 設計水量及水質 ....................................................7 設計水量 ......................................................7 設計水質 ......................................................7第三章 工藝設計方案的確定 ...............................................8 方案制定的原則 ....................................................8 污水處理工藝流程的確定 ............................................8 廠址及地形資料 ................................................8 工藝流程方案及簡易的工藝流程圖 ...............................10 主要構筑物的選型 .................................................11 格柵 .........................................................11 泵房 .........................................................11 調節池 .......................................................11 隔油池 .......................................................11 氣浮池 .......................................................12 A/O 池 ........................................................12 二沉池 ........................................................13 污泥濃縮池 ....................................................13第四章 污水處理系統的工藝設計 ..........................................14 格柵 .............................................................14 設計參數 .....................................................14 格柵的設計計算 ...............................................14 進水泵房 .........................................................18 泵的計算 .....................................................18 調節池 ...........................................................19 設計參數 .....................................................19 設計計算 ................................................
