摘要:	隨著時代的進步及都市化的腳步加快，目前國內河川的污染日益嚴重，加上目前國內大多數污水管線老舊，新建及更換的速度又太慢，無法妥善做好污水的收集與處理，更顯現地下污水管線的重要，因此目前政府開始積極進行國內污水下水道建設。而國內進行污水下水道規劃、設計時，首先必須探討的就是目標區域的污水產生量，污水量之推估對設計、建造及營運影響極大，也是下水道工程成敗之關鍵，目前對污水量之推估多採用國外相關文獻資料所訂定的準則，對於台灣地區都市特性之實際流量量測及調查較少，故將國外的經驗公式或者係數應用至台灣地區之下水道設計有失其準確性及真實性，因此，建立一個良好的污水量推估方法有其必要。以目前進行中的楠梓污水下水道系統BOT案為例，楠梓地區的污水量推估不僅影響到工程設計的安全、及實用性，對工程設計的經費、污水處理的收費機制、以及污水廠及污水管網的營運操作皆有直接的影響。本研究為探討台灣地區合理之污水下水道設計流量推估，故於高雄市已完成用戶接管區域，選取2個區域，進行連續24小時為期一個禮拜流量實測及理論污水量推估之檢討，藉由上述實際調查與分析成果，以高雄市楠梓污水下水道系統BOT案為對象，進行污水量、設計水量之推估，發展一個寄合理正確及可行的污水量推估方法，並與原有設計結果比對，探討目前設計標準的各式參數之實用性。 Following with the improvement of the era and the fast urbanization, the pollution to the river has become more and more severe in our country. In addition to that, most of the sanitary sewer pipes are old, the rehabilitation and the alternation are too slow that causing people unable to collect and dispose it. Therefore the sewer system has become more important. Consequently, the government commence constructing the wastewater sewer system progressively, including the rehabilitation, the alternation of the pipes and the planning of the wastewater system, etc. In Taiwan, when wastewater engineer begin to plan and design a wastewater system for a project, first of all is to probe into the amount of the wastewater, the evaluation of it influences the design, construction and even the operation of the system, besides, it is also the crucial part of the project.. Thus, it is vital to build an sound appraisal method of the amount of the wastewater. Using the ongoing Nanzi wastewater sewer system BOT project as an example, the evaluation of the amount of the wastewater not only affect the safety and the practicability of the design, but also influence the designing cost, payment mechanism and the operation of the both pipeline system and WWTP directly. This study is to probe into the appraisal of the design flow reasonably, first, select 2 areas which have already been completely constructed with the house connection, implement 24-hour survey of the actual flow for a week and compare the surveyed readings with the theoretical estimation of the amount of the wastewater. After that, utilize the result above in the Nanzi wastewater sewer system BOT project, evaluate the amount of the wastewater and design flow. Finally, develop a reasonable and practical means to appraise the wastewater, and also check the validity of using the design parameters.
