Physical Methods of Removing Biofouling Limnoperna fortunei in Hydraulic Engineering
摘要
Abstract
Hydraulic projects in south China often suffer from the biofouling hazards of limnoperna fortunei which ad-heres to the surface of structures in high -density, changing the function of structure buildings and affecting the safe operation of hydraulic projects.Through researching the mortality characteristics of limnoperna fortunei under condi-tions of drying, high water temperature, ultrasound wave, and electric current, we discuss the feasibility of remo-ving limnoperna fortunei using physical methods.Results revealed that limnoperna fortune died three days after being in dehydration condition at 28 ℃; and 10 hours in high temperature (44 ℃) ; when the water temperature is high-er than 55 ℃, limnoperna fortunei died instantly contacting with water.Ultrasonic wave and high pressure electric current in water could also kill larva and adult limnoperna fortune effectively.Among the four methods, dehydration and high temperature are the most effective , while ultrasonic wave and electric current are of good prevention effect .关键词
