In the past century, the world witnessed more and more challenges and crises of morality, society, culture, etc. as well as a great development of science and technology. Therefore, it is high time that we equip children and young people through education with the capacity to lead meaningful and productive lives in a world of bewilderingly rapid and complex change.

在过去的一个世纪里，科学技术的空前发展给人类带来了巨大的财富与希望，也给人们带来了重大的道德、社会、法律和文化的挑战与危机，例如，人类的生命，甚至是生命本身的概念，如今正面临着生物科学的发展以及生化和基因技术发展的挑战。

Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.

So in order to deal with the problem, both the living habit and distribution of Chironomus larva in the water treatment system and the methods in removing Chironomus larva at present were introduced in this article. Meanwhile, the relationship between its physiological characteristic and environmental factors was demonstrated. Also the research status、advantage and limitation of different methods in the remove of Chironomus larva were analyzed systematically and some scientific tendencies were prospected. It was suggested that enhancing the management to the raw water and optimizing the drinking water treatment processes were the feasible ways to effectively control the pollution.

本文首先介绍了摇蚊幼虫的生活习性及其在水处理工艺中的分布规律，然后对其生理特性与环境因子之间的关系进行了论述；并就近年来采用物理法、化学法和生物法防治水处理工艺中摇蚊幼虫污染的研究进展、现状和局限性进行了较为系统的分析，展望了摇蚊幼虫污染防治技术的研究前景，指出目前控制饮用水中摇蚊幼虫污染必须将水源水质水控制、污染治理与净水工艺处理结合起来，优化水处理工艺和强化水源水体保护是根本保障。
