水力扰动及底泥悬浮对藻类生长影响的试验
Effects of Hydraulic Disturbance and Sediment Suspension on Algae Growth
摘要
Abstract
In recent years,the eutrophication of water has become more and more serious,which leads to frequent algal outbreaks in rivers,lakes and reservoirs,seriously affecting water supply safety.In order to explore the effects of hydraulic disturbance and sediment suspension on algal growth in water,in situ algal samples of JZ Reservoir were taken as research objects to study their growth effects under different disturbance rates and sediment suspension.The results showed that,hydraulic disturbance of 100 r/min could effectively promote the growth of Cyanobacteria in water,and after exceeding the critical disturbance rate,the growth of algae will be significantly inhibited with the increase of the disturbance rate at 200~400 r/min.In the case of sediment suspension caused by hydraulic disturbance,chlorophyll a was significantly reduced,and the removal rate could reach about 82.4%after 4 h,which had a significant inhibitory effect on algae growth.Using this way can effectively control the propagation and outbreak of Cyanobacteria.关键词
