摘要
本文据1988年8～11月共6个航次采用多船同步、浮子跟踪和化学监测相结合的方法所获得的资料,研完了筼筜湖纳潮排污污水对厦门西港水质影响的范围和污染程度。
Based on the survey data of the six voyages during the period from August to November, 1988, the area and extent of the impacts of flood-in-ebb-out discharge of sewage water of Yuandang Lake upon the Western Harbour of Xiamen were studied . The results of survey indicate that: the dilute dispersion area of the sewage water discharged from the Yuandang Lake along ebb direction in the Western Harbour was 0.75～2.7 km^2,which was determined by the criterion of COD≥2. 0mg/L; the area seriously polluted was 0.5～0.8 km^2 on the sea surface near the outfall; the dispersion area was related to the total discharge and tides; the dispersion area could be reduced by the discharge of treated sewage in high tides; polluted sea water moved northward along flood-direction could reach the sea area near Shihu Dock; when polluted water reached the area, the content of COD was almost the same as the background before discharge; the water quality was only slightly affected. The author suggests that the manner of offshore and deep-water discharge of sewage be adopted in order to reduce the extent of Western Harbor of Xiamen pollution caused by the discharge.
