深圳水源水和給水處理系統中的搖蚊優勢種屬為花翅搖蚊。As a consequense of eutrophication, chironomid larvae excessively propagates in water sources, such as reservoir and fresh lake, which induced the 1st instar larvae of chironomid in source water to enter drinking water treatment system
水體富營養化使得搖蚊幼蟲在水庫、湖泊類水源中大量孳生繁殖，直接導致其可以在給水處理系統中出現。Study of killing and removal on chironomid larvae with oxidants in water treatment system
給水處理過程中搖蚊幼蟲的氧化殺滅與去除Control of chironomidae larvae in water treatment by bacillus thuringiensis var. israelensis de barjac
蘇雲金桿菌以色列變種防治水處理中搖蚊幼蟲研究Although there are no indications that these organisms pose a threat to public health, their presence is still not appreciated because most people associate the organisms with low hygiene
盡管目前不能證實搖蚊幼蟲會威脅到公眾健康，但是人們常常把這些生物的存在和飲用水不衛生聯系起來，引起他們對水質信心的下降。Advances in the studies on infesting and controlling chironomids in municipal water system
城市供水系統搖蚊污染發生與防治研究Development, growth, survivor and reproduction of the experimental populations of chironomus kiiensis were observed at 18, 22, 26, 30 and 34 respectively
在18 、 22 、 26 、 30和34五個恆定溫度下，研究了溫度對花翅搖蚊的生長發育、存活及繁殖的影響。It was found that under 18 34 the developmental duration decreased while the developmental rate increased linearly with temperature. the relationship between the developmental rate and temperature were further described with five regression equations, which could be applied to predict occurrence period and effective accumulative temperature
在試驗溫度范圍內，花翅搖蚊各蟲態發育歷期隨溫度升高而逐漸縮短，發育速率與溫度呈正比關系，並得出各蟲態發育速率與溫度的5個回歸關系式，可用於花翅搖蚊發生期的有效積溫預測。This study attempted to settle the danger of chironomid larvae as to ensure drinking water security by two approaches : one is to research on physiology and ecology of chironomid larvae in order to provide basis data for the forecast of chironomid larvae and service to the departments of water supply for solving breaking - out of chironomid larvae ; the other is to effectively remove chironomid larvae from water by strengthening water treatment process as to attain the radical solution for the problem of chironomid larvae
本研究旨在通過兩條途徑來解決給水處理系統中搖蚊幼蟲的威脅:一是研究搖蚊幼蟲的生理生態學特性，為搖蚊幼蟲的預測預報提供基礎數據，以指導水廠在其暴發期間採取應急措施;另一條途徑則是從改進與強化水處理工藝入手，研究行之有效的水處理工藝技術，達到使其被有效去除的目的。Several researchers reported that chironomid larvae is difficult to inactivate using free chlorine at concentrations commonly used in drinking water utilities. in addition, the 1st instar larvae can easily penetrate sand filter and then goes into waterworks reservoir and municipal service pipe due to its motility
1齡搖蚊幼蟲具有較強的游動性，可以穿透濾池進入到清水池中，由於常規的水處理消毒工藝對其難以有效地滅活，在我國一些大中城市的管網水中都曾發現過搖蚊幼蟲。分享友人
