污水廠功能設計

民治污水處理廠功能計算書一、前言本計算書為針對某流域潮萬污水下水道系統之民治污水處理廠新建工程設計工作，所進行之處理廠各單元功能計算。本計算書共分十個單元進行計算，除前處理及進流抽水站採用尖峰小時流量為功能設計基準外，其餘單元原則上採用最大日流量為功能設計基準。1.進流污水水量平均日流量=22,840CMD=0.264CMS=6.03MGD最小日流量=平均日流量x0.65=14,850CMD最大日流量=平均日流量x1.33=30,400CMD尖峰小時流量=平均日流量x2.00=45,700CMD2.進流污水水質進流BOD5=200.0mg/L進流TSS=200.0mg/L進流NH3-N=25.0mg/L進流TP=8.0mg/L3.設計放流水水質出流BOD5=20.0mg/L出流TSS=20.0mg/L出流NH3-N=10.0mg/L出流TP=4.0mg/L2020/1/22Page.14.尖峰小時流量質量平衡計算結果(1)污水部份污水名稱流量TSSBOD5TPCMDKg/dmg/LKg/dmg/LKg/dmg/L進流污水45,7009,140200.09,140200.0365.68.0迴流水合併3,2171,204.3547.6402.6183.147.521.6初沉池進流48,91710,344211.59,543195.1413.18.4初沉池出流48,7634,13884.97,062144.8367.67.5二沉池出流48,095961.920.0327.06.824.00.5砂濾池出流45,805458.010.024.00.511.50.3濃縮機清洗水72.00.710.00.00.50.020.3脫水機清洗水96.01.010.00.10.50.020.3放流水45,637456.410.023.90.511.40.3濃縮濾液(迴流)638.7275.9432.083.3130.417.226.9脫水濾液333.0524.31,57440.6122.0353.91,062.6除磷單元出流水288.3424.51,47316.256.417.761.4(迴流)砂濾反洗水(迴流)2,290503.9220.0303.1132.312.65.5(2)污泥部份污泥名稱流量TSSBOD5TPCMDKg/dmg/LKg/dmg/LKg/dmg/L初沉污泥154.26,20740,2412,48116,08645.4294.6廢棄活性污泥667.95,3438,0001,6642,492343.3513.9濃縮廢棄活性污泥101.25,10050,3781,58115,618326.13,221化學污泥44.82,24850,20924.4544.4336.27,510消化污泥255.511,30744,2584,06215,901371.51,454消化後污泥255.57,91530,981786.93,080371.51,454脫水污泥300.210,16233,848811.32,702707.72,357脫水污泥餅63.29,700153,453770.712,193353.95,5982020/1/22Page.25.最大日流量質量平衡計算結果(1)污水部份污水名稱流量TSSBOD5TPCMDKg/dmg/LKg/dmg/LKg/dmg/L進流污水30,4006,080200.06,080200.0243.28.0迴流水合併2,199802.0364.7268.2121.931.614.4初沉池進流32,5996,882211.16,348194.7274.88.4初沉池出流32,4962,75384.74,698144.6244.67.5二沉池出流32,052641.020.0218.06.816.00.5砂濾池出流30,526305.310.016.00.57.60.3濃縮機清洗水72.00.710.00.00.50.020.3脫水機清洗水96.01.010.00.10.50.020.3放流水30,358303.610.015.90.57.60.3濃縮濾液(迴流)448.9183.7409.355.4123.411.425.5脫水濾液253.7349.11,37627.0106.6235.4928.0除磷單元出流水223.9282.51,26210.848.311.852.6(迴流)砂濾反洗水(迴流)1,526335.8220.0202.0132.38.45.5(2)污泥部份污泥名稱流量TSSBOD5TPCMDKg/dmg/LKg/dmg/LKg/dmg/L初沉污泥102.64,12940,2411,65116,08530.2294.6廢棄活性污泥444.23,5548,0001,1072,492228.351
