热能喷雾处理反渗透浓盐水的实验研究

摘要

Because that the high concentration of salt in the discharge from the Reverse Osmosis will disserve the environ-ment, we study a now way Thermal Spray to dispose the brine.In the end, we can conclude that the technology's efficiency can reached 90%,when its conditions are under the heat value of 4.8*106 kcal, air flow rate is 60 m3/h.Its output of condensate water is almost up to the standards of drinking water;and in the capacity of 10~12 L/h, it can attain wastewater zero discharge;When capacity is greater than 12 L/h, the wastewater TDS is quite high.%目前，反渗透废水中，高浓度的含盐量会对环境带来严重危害。本研究运用热能喷雾处理反渗透浓盐水技术，对反渗透（Reverse Osmosis，RO）出水进行处理。结果表明，该技术在热量值为4.8×106 kcal、空气流量为60 m3／h的条件下，处理效率达到了90％以上。产出的冷凝水的水质符合饮用水的相关标准；在处理量为10 L／h～12 L／h时，可达到废水零排放的效果；在处理量大于12 L／h时，排出的废水总溶解物（ Total dissolved sol-ids，TDS）很高。
