Method and system for regenerating and recovering calcium carbonate from reverse osmosis concentrated water
The invention discloses a method and a system for regenerating and recovering calcium carbonate from reverse osmosis concentrated water, and belongs to the technical field of water treatment. Calciumand magnesium ions and high-valence metal ions in the concentrated water are precipitated and separated by Ca (OH) 2 to obtain a calcium carbonate product so that the concentrated water is regeneratedand converted into raw water. The connection breakthrough of the wastewater regeneration field and the inorganic salt industrial technology is realized, the effects of wastewater regeneration and solid waste zero discharge show extremely obvious technical progress, the capacity of recycling concentrated water resources and recycling high-added-value calcium carbonate finished products to turn waste into wealth represents the development direction in the future, and the technical scheme has the advantages of being small in investment, convenient to match, easy to operate, low in operation costand the like, and the wide popularization prospect of the method is determined.
一种反渗透浓水再生回收碳酸钙的方法及其系统，属于水处理技术领域。采用Ca(OH)将浓水中钙镁离子及高价金属离子沉淀分离出来得到碳酸钙产品，使浓水再生转化为原水。实现了废水再生领域与无机盐工业技术的衔接突破，其废水获得再生和固废零排放的效果显示出极其明显的技术进步，其浓水资源化利用且回收出高附加值碳酸钙成品变废为宝的能力代表了今后的发展方向，其技术方案本身表现的投资少、配套方便、操作简单、运行成本低等方面优点决定了其广阔的推广前景。
