基於水質模擬系統軟件(WASP)計算下的某河流水質狀態分析研究

摘 要 ：本文針對某河流水質狀態分析評價 ，引入綜合水質模型（WASP）開展模擬計算研究 ，獲得了綜合水質模型（WASP）模擬計算結果與斷面實測數據基本一致 ，且相對誤差值亦均在允許范圍內 ，模型匹配性較佳 。 河流水質受河兩岸地質條件及工業產區空間分布影響 ，工業產區及人流量活動大的區域 ，水質狀態不佳 。 研究表明降雨量一定程度上會提升水質清潔度 ，但降雨量超過一定程度時 ，降雨會帶來河流水質二次污染 ；污水處理廠中排出水質污染物濃度與河流水質狀態並無明顯關聯 ，但排出水量與河流水質狀態成反比 。 研究成果為水質模型模擬計算方法在河流水質狀態分析評價中應用提供一定參考 。

WASP(The water quality analysis simulation program,水質分析模擬程序)是EPA推薦使用的水質模型軟件,使用較為廣泛,能夠模擬河流、湖泊、水庫、河口等多種水體的穩態和非穩態的水質過程。

The Water Quality Analysis Simulation Program (WASP) is an enhancement of the original WASP (Di Toro et al., 1983; Connolly and Winfield, 1984; Ambrose, R.B. et al., 1988). This model helps users interpret and predict water quality responses to natural phenomena and manmade pollution for various pollution management decisions. WASP is a dynamic compartment-modeling program for aquatic systems, including both the water column and the underlying benthos.

水質分析模擬程序（WASP）是對原始WASP的改進（Di Toro等人，1983年；Connolly and Winfield，1984年；Ambrose，R.B.等人，1988年）。該模型有助於用戶解釋和預測水質對自然現象和人為污染的響應，從而做出各種污染管理決策。WASP是一個用於水生系統的動態隔間建模程序，包括水柱和底層底棲生物。

WASP allows the user to investigate 1, 2, and 3 dimensional systems, and a variety of pollutant types. The state variables for the given modules are given in the table below. The time varying processes of advection, dispersion, point and diffuse mass loading and boundary exchange are represented in the model. WASP also can be linked with hydrodynamic and sediment transport models that can provide flows, depths velocities, temperature, salinity and sediment fluxes. This release of WASP contains the inclusion of the sediment diagenesis model linked to the Advanced Eutrophication sub model, which predicted sediment oxygen demand and nutrient fluxes from the underlying sediments.

WASP is one of the most widely used water quality models in the United States and throughout the world. Because of the models capabilities of handling multiple pollutant types it has been widely applied in the development of Total Maximum Daily Loads (TMDL). WASP has capabilities of linking with hydrodynamic and watershed models which allows for multi-year analysis under varying meteorological and environmental conditions. WASP has been applied to all of the major estuaries in Florida where it was linked with a hydrodynamic and watershed model simulating 12 continuous years to aid US EPA in the development of numeric nutrient criteria. Other examples of its use are:

• eutrophication of Tampa Bay, FL;
• phosphorus loading to Lake Okeechobee, FL;
• eutrophication of the Neuse River Estuary, NC;
• eutrophication Coosa River and Reservoirs, AL;
• PCB pollution of the Great Lakes;
• eutrophication of the Potomac Estuary;
• kepone pollution of the James River Estuary;
• volatile organic pollution of the Delaware Estuary; 
• heavy metal pollution of the Deep River, North Carolina; and
• mercury in the Savannah River, GA.
