高压静电场对绿色阻垢剂的阻垢性能和水垢晶型的影响

INFLUENCE OF HIGH-VOLTAGE ELECTROSTATIC FIELD ON THE SCALE INHIBITION PERFORMANCE OF ENVIRONMENTALLY FRIENDLY SCALE INHIBITION AGENT AND THE CRYSTAL FORMS OF SCALE

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 influences of high-voltage electrostatic field on the scale inhibition performance of polyepoxysuccininc acid （PESA） and the crystal forms of scale were investigated. The results of the static scale inhibition experiments show that synergistic scale inhibition effect is obviously exist at the electrostatic field and PESA. When the electrostatic field is 5 000 V and the dosage of PESA is 6 mg/L, the rate of static scale inhibition is 95.4%, which is 22.3% higher than that in the non-electrostatically treated water sample. The results of SEM and XRD show that the content of aragonite in the deposited sample is increased, which indicate the electrostatic field is advantageous to the aragonite generation.
