焦化反渗透浓水除氟试验研究OA
An Experimental Study on Defluorination of Reverse Osmosis Concentrated Coking Wastewater
考察了Ca(OH)2和CaCl2两种钙盐在反渗透浓水中的除氟效果。研究了Ca(OH)2和CaCl2除氟药剂投加量，合适的pH值，以及反渗透浓水中氯离子、硫酸根离子对除氟的干扰作用。试验结果表明：直接投加Ca(OH)2为3000 mg/L时或调节焦化反渗透浓水的pH值>9、CaCl2投加量为2000 mg/L时，出水氟离子低于10 mg/L，达到国家废水排放标准。
The defluorinating effect of Ca(OH)2 and CaCl2 for reverse osmosis concentrat-ed water was investigated and the addition dose, optimal pH value and interference of chlo-ride ion in reverse osmosis concentrated water and sulfate ion on defluorination effect were studied. The experiment results indicated that when directly dosing 3000 mg/L of Ca (OH)2 or adjusting the pH>9 of the concentrated water and directly dosing 2000 mg/L of CaCl2, the content o…查看全部>>
