摘要
工業區污水處理廠的營運績效管理，是為了經濟部工業局推動工業區業務中重要且重視的一圜，每年訂定各項的管理績效指標、操作績效指標、維護績效指標及水質檢驗績效指標，作為污水處理廠年度工作執行目標。，因為製程廢(污)水之水質特性複雜，所以對於污水收集系統及污水處理廠處理設施而言負荷變異性大，係以收集105年及106年至108年之「月平均處理水量(m3/月)」、「月平均收費水量(m3/月)、「水量收費率(%)」、「COD收費率(%)」、「SS收費率(%)」、「單位廢水收入(元/m3)」、「單位廢水成本(元/m3)」、「月平均維護費(元)」、「月平均污泥處置費(元)」、「單位水量電力費(元/m3)」、「單位水量藥劑費(元/m3)」等，以線性迴歸及ANOVA等統計方法來探討其相關性，可作為未來評估大園工業區污水處理廠訂定績效指標的合理性參考。還有分級累進收費制度當初修訂僅針對水量及水質加以分級，並未對行業別水質進一步限制，仍屬於同一費率。部份收費制度對於行業別能達「公平性」與「合理性」真正收費原則。污水處理廠的操作若欲藉由「設備」、「維護」、「藥劑」、「污泥」等來降下減少支出，想利用這樣的方式結果成效是很有限的，但具有節能減碳之精神，仍需更進一步的探討。

Abstract
The operation performance management of the sewage treatment plant in the industrial zone is important and for the Industrial Bureau of the Ministry of Economic Affairs to promote the business of the industrial zone. Various management performance indicators, such as operation performance indicators, maintenance performance indicators and water quality inspection performance indicators are set every year. , as the annual work implementation target of the sewage treatment plant . It is discharged into the sewage treatment plant in the industrial area for treatment, and because the water quality characteristics of the process waste (sewage) water are complex, the load variability of the sewage collection system and the treatment facilities of the sewage treatment plant is large . Linear regression and ANOVA were used to explore the correlation between "monthly average water volume (m 3 /month)", "monthly average charged water volume ( m 3 /month ) ", "water volume rate (%)", "COD rate (%)", "SS rate" in (%)", "unit wastewater revenue (NT$/m 3 )", "unit wastewater cost (NT$/m 3 )", "monthly average maintenance fee (NT$)", "monthly average sludge disposal fee (NT$)" , "electricity fee per unit of water volume (NT$/m 3 )", "pharmaceutical fee per unit water volume (NT$/m 3 )", etc to evaluate of the performance of Dayuan industrial area sewage treatment plant. There is also a grading and progressive charging system that was revised only for water quantity and water quality, and did not further restrict water quality by industry, and it still belongs to the same rate. Part of the charging system does not meet the true charging principles of "fairness" and "reasonableness" for the industry. If the operation of the sewage treatment plant wants to reduce the expenditure by means of " equipment ", "maintenance", "chemical dosing", "sludge reduction", etc. The result of using this method is very limited, but it has the spirit of energy saving and carbon reduction. , still needs to be further explored。
