市民除了可以透過傳媒得知空氣污染指數外，亦可致電空氣污染指數熱線28278541或到訪環境保護署網頁http : www . epd - asg . gov . hk cindex . php查詢有關資料。In this paper, river water quality prediction is integrated with water pollution control measures. two parameters, water environmental capacity and pollution index are selected for pollution control measures. the objective is achieved after the development of simulation model using one - dimensional advection dispersion equation. the model algorithm and computer program is an improvement over the existing water quality models, since the model solution involves four point implicit upwind schemes for water quality prediction and pollution control measures at each grid point. model simulation results the assessment of water environmental capacity that yield the acceptable and realistic pollutants concentration in order to maintain water quality objectives. the pollution and overall pollution index of the river is suggested for integrating number of contaminants variables into one index. study provides the mathematical and scientific procedure for water quality management. the new approach is helpful for the water pollution control and to study the impacts of waste effluents on the river system for strategic planning purposes
本文將水質預測及水污染控制措施有機地結合，選取水環境容量和污染指數作為水污染控制的參數.這樣，一維對流-擴散水質方程的求解除就是實現本研究目的的關鍵.本研究採用的模型在現有的水質模型基礎上有所改進，因為其採用四點隱格式對水質進行預測，推求可接納污染物的環境容量值及為保證水質而限定的污染物濃度值，從而制定相應的水污染控制措施.為整體考慮各種污染物的情況，建議採用河流的污染指數進而推求綜合污染指數.總之，本研究為水質保護提供了科學的計算方法，該法對水污染控制及污水對河道水質的影響是實用有效的Abstract : in this paper, river water quality prediction is integrated with water pollution control measures. two parameters, water environmental capacity and pollution index are selected for pollution control measures. the objective is achieved after the development of simulation model using one - dimensional advection dispersion equation. the model algorithm and computer program is an improvement over the existing water quality models, since the model solution involves four point implicit upwind schemes for water quality prediction and pollution control measures at each grid point. model simulation results the assessment of water environmental capacity that yield the acceptable and realistic pollutants concentration in order to maintain water quality objectives. the pollution and overall pollution index of the river is suggested for integrating number of contaminants variables into one index. study provides the mathematical and scientific procedure for water quality management. the new approach is helpful for the water pollution control and to study the impacts of waste effluents on the river system for strategic planning purposes
