【摘要】：我國西北地區(qū)干燥少雨、蒸發(fā)量大,蓄水工程蒸發(fā)損失了大量的水資源。為研究干旱地區(qū)的水資源保護措施,以十六醇和乙醇為分子膜基材,采用超聲波分散技術(shù),制備了一種非均相體系水分蒸發(fā)抑制劑。對兩種醇的比例、超聲處理時間及功率、抑制劑加入量對抑制效果的影響進行了研究。結(jié)果表明:十六醇與乙醇比例為1∶6,超聲處理功率6 k Hz,時間為25 min,每處理30 s停歇10 s的情況下,水分蒸發(fā)抑制劑效果最佳,24 h抑制率可達45.3%,抑制劑用于水面后,水體含氧量與自然條件下水體含氧量大致相同,不會對水生動植物的生長產(chǎn)生影響。所配抑制劑對于減少干旱地區(qū)水資源損失具有重大意義,可帶來巨大的經(jīng)濟效益和社會效益。
[Abstract]:In the northwest of China, there is a large amount of evaporation and water resources are lost by evaporation. In order to study the water resources protection measures in arid areas, a heterogeneous water evaporation inhibitor was prepared by ultrasonic dispersion technique using hexadecanol and ethanol as molecular membrane substrates. The effects of the ratio of two alcohols, ultrasonic treatment time and power, and the amount of inhibitor on the inhibition effect were studied. The results showed that when the ratio of hexadecanol to ethanol was 1: 6, the ultrasonic power was 6 kHz, the time was 25 min, and the time was 25 min, the best inhibition rate of water evaporation inhibitor for 24 h was 45.3% after treatment for 30 s. The oxygen content in water is about the same as that in natural conditions, and it will not affect the growth of aquatic plants and animals. These inhibitors have great significance in reducing water resources loss in arid areas and can bring great economic and social benefits.
