研究了在经过高压静电场处理后的水样中,绿色阻垢剂聚环氧琥珀酸(PESA)的阻垢性能及水样中生成的碳酸钙形貌和晶型组成的变化。静态阻垢试验结果表明,PESA和高压静电场存在明显的协同阻垢作用,当静电压为5 000 V,药剂用量为6 mg/L时,阻垢率可达95.4%,比单独使用PESA时提高了22.3%。SEM和XRD的测试结果表明,水样经过静电场处理后,水垢中文石型碳酸钙的含量提高,说明静电场的存在有利于文石型碳酸钙的生成。
The scale inhibition performance of green scale inhibitor polyepoxysuccinic acid (PESA) and the changes of the morphology and the crystalline composition of calcium carbonate formed in the water samples were investigated in water samples after high voltage electrostatic field treatment. The results of static scale inhibition show that there is obvious synergistic scale inhibition effect between PESA and high voltage electrostatic field. When the electrostatic voltage is 5 000 V and dosage of 6 mg / L, the scale inhibition rate is up to 95.4%. Compared with PESA alone, Increased by 22.3%. The SEM and XRD results show that after the electrostatic field treatment, the content of Chinese stone calcium carbonate increases, indicating that the existence of electrostatic field is beneficial to the formation of aragonite calcium carbonate.
