文 献 综 述城市给水处理工艺综述摘要：随着城市经济建设的快速发展，人们生活水平的提高。

城乡人民对生活和工业生产的用水以及用水水质、水量保证率要求日益迫切。

混凝、沉淀、过滤、消毒等常规的水处理技术由于运行周期长、成本较大以及水处理效率不高的缺点，已经不能满足人们的需求。

为了更好的满足人们的迫切需求，我们可以用当前较为新颖的水处理技术来改善常规水处理技术的不足。

新的水处理技术包括：生物絮凝剂、臭氧-生物活性炭工艺、聚合硫酸铁、紫外线消毒技术等等。

关键字：水处理技术，生物絮凝剂，紫外线消毒，臭氧-生物活性炭工艺。

Discussion on urban water supply treatment technologyAbstract:With the rapid development of urban economic construction, the improvement of peoples living standards. Urban and rural people on life and industrial production of water and water quality, water assurance rate demand increasingly urgent. Conventional water treatment technologies such as coagulation, precipitation, filtration and disinfection can not meet peoples needs because of the disadvantages of long operation cycle, high cost and low water treatment efficiency. In order to better meet the urgent needs of people, we can use the current relatively new water treatment technology to improve the shortcomings of conventional water treatment technology. New water treatment technologies include: biological flocculant, ozone-biological activated carbon process, reclaimed water reuse technology, polyferric sulfate, ultraviolet disinfection technology and so on.Key words: water treatment technology, biological flocculant, ultraviolet disinfection, ozone-biological activated carbon process.一、常规传统处理工艺目前，我国经常使用的水处理工艺包含四个部分：混凝技术、沉淀技术、过滤技术、消毒技术。

这些常规的水处理技术通常是通过吸附水体中的有机颗粒物质，将过滤水里面含有的病毒物,然后提高水环境质量，达到净化水体的目标。

［1］1.1混凝技术混凝技术是水处理过程中最常见也是最基本的不可或缺的一个重要过程。
