利用化学反应方程,推算与水化学稳定性有关的游离CO_2、侵蚀性CO_2、饱和pH_8及去除侵蚀性CO_2所需要CaCO_3的量的计算方法,计算珠江水体稳定性参数,分析珠江流域侵蚀性CO_2分布状况。结合珠江实际情况,提出了对具有侵蚀性水体,采用调整pH大于8.3或加进CaCO_3或加进石灰,或加进CaCO_3,和曝气相结合的方法,使水体达到化学稳定。
The chemical reaction equation was used to calculate the amount of free CO_2, corrosive CO_2, saturated pH_8 and CaCO_3 required to remove aggressive CO_2 related to the chemical stability of water, and the calculation of the stability parameters of the Pearl River water body and the analysis of the distribution of erosive CO_2 in the Pearl River Basin situation. Combined with the actual situation in the Pearl River, it is proposed to make the water body chemically stable with aggressive water by adjusting the pH above 8.3 or adding CaCO 3 or adding lime, or adding CaCO 3 and aeration.
