【摘要】 本文论述了在胶州湾用罗丹明B作示踪剂,模拟可溶性污染物的稀释扩散,采用水中荧光计现场实地检测及取样实验室分析,共进行了五次实验。实验表明:风、浪、潮、流对扩散速度都有一定的影响,发现了罗丹明B染料云团随海流运动的规律。总的说来,污染物在胶州湾的稀释扩散速度较快,也就是说胶州湾的自净能力较强。如果合理地选择排污地点和气象因素,就能充分发挥其自净能力。更多还原

【Abstract】 A modeling experiment on the dilution and diffusion of soluble contaminators in Jiaozhou Bay using Rhodamine-B as a tracer was performed five times. In determining the diffusion velocity of Rhodamine-B in sea water, it was shown that wind, current, wave, and tide all influenced the velocity and the regular pattern of the movement of the dye cloud mass of Rhodamine-B along with sea current was found out.In a word, the diffusion velocity of contaminators was fairly fast, the dilution factor reached over 104 after 20 minutes, i.e. the capacity of self-purification of Jiaozhou Bay was strong. If the site of pollutant discharge and meteorological factors are selected rationally, the capacity of self-purification can be brought into full play.更多还原
