分析了现状供水水质的化学稳定性,试验并模拟在与现状地表水不同混配比例条件下水质化学稳定性情况,确定了海水淡化水在有限水量控制条件下最经济的安全引入市政供水管网的解决方案。通过采用溶解天然石灰石法对海水淡化水进行矿化中试研究,为海水淡化水大规模进入市政供水管网提供了化学稳定性控制的解决方案。应用结果显示,根据进入市政管网海水淡化水量采用适宜的方案对供水水质的化学稳定性进行控制,在保证供水安全稳定运行的同时,对缓解水厂供水能力不足问题是非常有效的。
The chemical stability of the current water quality was analyzed. The chemical stability of water quality was tested and simulated under the condition of different mixed proportion with the present situation of surface water. It was determined that the desalinated water was the most economical and safe to be introduced into the municipal water supply network s solution. The pilot study of mineralization of seawater desalinated water by dissolving natural limestone provides a solution to the chemical stability control of seawater desalinated water entering the municipal water supply network on a large scale. The application results show that according to the amount of desalinated water entering the municipal pipe network, appropriate solution is adopted to control the chemical stability of water quality, which is very effective in alleviating the shortage of water supply capacity of waterworks while ensuring the safe and stable operation of water supply.
