定期監測雨水渠和河水水質 The water quality of storm drains and streams is regularly monitored. 監測建築工地的職業噪音和環境噪音 Monitoring theoccupational nd environmental noise levels of construction activities 控制污染和廢物管理 為確保校園空氣素質和員生健康，大學嚴格遵守 各項環保法規，又推廣「停車熄匙」活動，減少汽 車排放廢氣；妥善保養各幢樓宇的通風和空氣調 節系統，並定期監測室內溫度、濕度、二氧化碳 和揮發性有機化合物濃度等。自八十年代起，大 學已制定戶內禁煙政策，務使中大成為「無煙校 園」。 本校建立了一個由雨水渠和污水渠組成的排水系 統，把雨水、路面和屋頂的流水引入天然水道， 而住宅、學生宿舍、辦公室、實驗室、飯堂的污 水則引往沙田污水處理廠。各飯堂也安裝了隔油 器，把油脂廢物和污水分隔，減輕污水處理廠的 負荷，另訓示清潔員工不得把污水或潤滑油、油 漆等化學廢料傾入雨水渠。此外，本校施行水質 監測計劃，定期檢查食水、沖廁水、冷凍水、泳 池水、排水系統、河流、湖泊等的水質，以確保 符合衛生和環境標準。 為消減噪音，大學根據法例進行各項改善措施及 發展計劃，並積極將住宅區的噪音控制在七十分 貝以下，而其他活動區域則有不同的噪音水平管 制。 Pollution Control and Waste Management To protect the health and well-being of the community, good air quality is ensured through legal compliance and plannings. 'Engine Off, Wait Green' is promoted to raise public awareness about green driving practices. The ventilation system of all academic and administrative buildings is properly maintained to ensure effectiveness. Monitoring of temperature, humidity, carbon dioxide, volatile organic compound, etc. is regularly conducted to ensure healthy indoor air quality. Indoor smoking control has been implemented since the 1980s to make the University a smoke-free campus. Storm drains were built to collect rain water and surface run-off from road surfaces and roof-tops, and to divert them into natural watercourses. Cleaners and workers are instructed not to discharge car-wash or spent lube oil and paint into the storm drains. Contaminated wastewater generated from residences, student hostels, offices, laboratories, canteens, etc, are discharged into sewers and channelled to Shatin Treatment Works. To reduce treatment loading, grease traps are installed in all canteens to segregate oil from wastewater. To ensure the effectiveness of these measures, water quality is regularly monitored at different locations such as drinking water tank, flushing water tank, chilling water tower, swimming pool, drainage system, stream and lake according to hygiene and environmental protection standards. 香港中文大學年報 CUHK Annual Report 2003-2004 88
