摘　　要：低温低浊水通过常规处理工艺难以达到要求,一直是给水处理领域的难题。阐述了低温、低浊对混凝效果的影响,从强化混凝工艺、改进沉淀工艺、增强过滤工艺3个方面探讨了国内外对低温低浊水处理技术的研究与应用,分析比较了预氧化技术、污泥回流技术、高密度沉淀池、磁技术、气浮技术、膜分离技术、微絮凝接触过滤技术、组合工艺的处理效果与存在问题,展望了各技术的发展前景。By conventional water treatment process, low temperature and low turbidity water is difficult to achieve the requirements, which is always a difficult problem in the field of the water treatment. The article states the influence of low temperature and low turbidity on coagulation, discusses the research and application of low temperature and low turbidity water treatment technology at home and abroad from three aspects of enhanced coagulation process, improved precipitation process and enhanced filtration process, analyzes and compares the treat effect and existing problems of pre-oxydation technology, sludge recycle technology, membrane separation technology, micro flocculation contacting filter technology, etc, and puts forward the application prospect of combination technology.
