楼主，你好！ 据楼主你所叙，应该是 红线虫 ： 专家认为，红线虫不是寄生虫，吃了虽不会对人体有直接危害，但由于它本身带有的细菌及它的排泄物都能引起人的胃肠不适，导致人们出现腹泻、恶心、呕吐等症状，同时它作为水体不干净的“指示生物”，它的存在说明自来水在运送过程中的某个环节受到了有机污染。 中文名： 红线虫 别名：丝蚯蚓、水蚯蚓、红丝虫、赤线虫，北方有称线蛇 种属：环节动物门，寡毛纲，近孔寡毛目，颤蚓科，水蚯蚓属 。 外形特征：样子像蚯蚓幼体。属环节动物中水生寡毛类，体色鲜红或青灰色，细长，一般长4厘米左右，最长可达10厘米。 但群体产量较高。尾鳃蚓和水丝蚓的区别是前者有尾鳃，尾部常露出泥外，随水摆动呼吸，缺氧时颤动加快；后者没有尾鳃。红线虫喜生活在有机质丰富的微泥水域的淤泥中，一般潜伏在泥面下10厘米～25厘米处，低温时深藏于泥中。红线虫喜暗畏光，不能在阳光下曝晒，以食泥土吸取其中的有机腐植质、细菌、藻类为生。红线虫2个月左右性成熟，雌雄同体，异体受精，卵粒包藏在透明胶质膜构成的囊状蚓茧中。它们多生活在江河流域的岸边或河底的污泥中，密集与污泥表层，一端固定在污泥中，一端生出污泥在水中颤动，一遇到惊动，立刻缩回污泥中。繁殖能力随着气温升高而增强。 发现自来水中有红线虫，主要原因是水箱或其它二次供水设施管理不善，未能及时清洗而造成污染，沉积在水箱内的蚯蚓卵孵化发育成红线虫。现水中有红线虫的现象，主要是因为夏季气温高、湿度大，适宜红线虫生长。红线虫大量存活于下水沟渠、管道之中。每到夜间，它们经常会从下水管道中爬出，沿着池壁和自来水管壁爬进用户自来水龙头的出口处，汇集成团状。用户清晨第一次用水时，将它们冲出，造成红线虫从自来水中流出来的假象。其次，如水龙头已经打开用水一段时间仍有红线虫流出，可能与水管的老化锈蚀水中微生物孳生有关，提醒用户要更换户内管道。 预防红线虫，关键要对水箱等二次供水设施及时清洗消毒，加强对水箱等二次供水设施的管理，及时进行维护清洗消毒。一般消毒每半年不得少于一次，防止水中红线虫生长；水中若出现红线虫，可用漂白粉杀虫；居住在平房及低矮楼层的用户应注意用水环境的卫生，保持自来水水池清洁，夜间尽量不要把扫把、抹布等潮湿的物体放置于自来水水池旁，同时可以用塞子将自来水水池下水口塞住；有条件的用户还可以经常用“84消毒液”、漂白粉、瓶装家庭消毒剂等对水槽、下水管道等长期潮湿的地带进行消毒，防止红线虫外爬。此外，家庭太阳能热水器如长期不用时也应把水完全放空，重新使用时应注意消毒清洗干净，否则也有可能孳生红线虫。 以上希望对你有帮助！
线虫，长时间不用的井里，容易出现此虫子。必须烧开后引用。
肯定有害！要找学校或者自来水公司反映，自己是没有办法消灭的。
红线虫，怎么说这些虫子对人体都身体都是有一定的危害的？可以在阳光下暴晒
