    著重研究了河流稀釋自凈需水量的計算方法，初步構建了考慮水體自凈與污水處理率及用水費用相結合的生態需水量優化模型，依據未來年份污水排放量的變化，預測生態需水量，並通過實例說明南方河流系統生態需水量的計算過程。
  2. To begin with, most of hong kong s sewage and wastewater ended up in the sea, but the bulk of it had received little or no treatment before discharge due to the lack of a developed sewer network and treatment facilities at that time. this led to rises in organic and inorganic pollutants, a reduction in the oxygen content of the water, and increased bacteria levels

    城市的生活污水和工業廢水一般均排入大海，但由於當時污水系統及處理設施並不完善，大部分污水只經過初步處理或甚至未經處理便予以排放，導致海水中有機和無機污染物不斷增加，含氧量下降和細菌水平上升。
  3. Optimal periodic control with the lowest operational cost by limiting total substrate discharge mass was studied. through adding new state variable and using supplement functions, the problem with restriction conditions was converted into nonrestriction problem. in addition, the dynamic searching method of optimal step coefficient was developed to modify the conventional gradient method, consequently the calculation problem of the multivariable optimal periodic control was able to be resolved better. it was found that the operational costs of optimal control under various initial states are distinctly different. a new concept of optimal control under optimal initial state was presented. it is pointed out emphatically that to the treatment system without optimal control condition, the suboptimal control with extensive practical value can be realized according to the results of optima control

    著重研究了在限制有機物排放總量時，使其運行費用最低的最優周期控制問題.通過增加新的狀態變量和用補償函數法，將本課題的有約束條件問題化為無約束條件問題，並提出了最優步長參數的動態搜索法來修改傳統的梯度法，從而較完善地解決了多變量最優周期控制的計算問題.研究中還發現了不同初始條件下最優控制所需要的運行費用也大不相同，進而提出了最優初始狀態下最優周期控制的新概念，這對保證出水質量的同時進一步降低污水處理成本來說具有更重要的意義.本文還強調指出：對于尚不具備實現最優控制條件的處理系統，可根據最優控制的研究結果實現具有廣泛實用價值的準最優控制
  4. The commissioning of a disinfection unit at the wastewater treatment facility for clear water bay second beach in early 2002 has also brought about improvements

    2002年初，清水灣第二灣污水處理設施的消毒裝置正式啟用，進一步改善了泳灘的水質。
