浅谈水处理技术的发展前景

摘要：众所周知，水是生命之源，是人类赖以生存不可缺少的宝贵资源，在经济日益发达的今天，人民对生活质量也有了更高的要求，因此，对水的质量问题也越来越重视。并且随着我国经济的不断发展，我国政府对水资源的保护也日益增加，关于水处理的技术要求也越来越高。尽管世界上有70%的水资源，但是可供人类利用的淡水资源却不多，而我国是一个水资源短缺的国家，再加上之前对水资源的浪费和污染，以及污染治理滞后，大量城市污水和工业废水未经处理排入水体使得水资源变得更为稀少。水污染治理和节水是两个非常重要的环节，只有在发展供水的同时，使排水和污水处理同时发展，才能保护水环境。在进入高新技术时代的我国，百分之九十以上的污水、废水是用生物技术处理的，生物工程等高技术将在水处理中得到广泛的应用。本文首先简要介绍我国目前水资源的现状，根据现状对水处理技术的方法作简单分析，接着详细阐述水处理技术在我国的发展前景。

The analysis in coming development of water treatment technology Abstract:As we all knows, water is the source of life, which is indispensable valuable resources for human’s survival. With the rapid of Chinese development, people's quality of life also have higher requirements, therefore, the quality of water is more and more attentive. And with the continuous development of our economy, government for the protection of water resources is also increasing, about water treatment techniques are increasingly high requirements. Although 70% of the water resources in world is at our country, available for human use of freshwater resources is a little. And China is a country who is short of water resources, plus before the waste of water resources and pollution, and pollution control lag, a lot of city sewage and industrial wastewater discharged into water bodies without treatment the water resources become more scarce. Water pollution control and water saving are two very important link, only in the development of water supply at the same time, the drainage and sewage treatment at the same time in order to protect the water environment. After China entered the era of high technology, sewage, waste water more than ninety percent is the use of biological treatment technology and high-tech biological engineering will be widely used in water treatment. First this paper briefly introduces the current situation of water resources in China. Second it makes the simple analysis method according to the situation of water treatment technology, and then elaborate on water treatment technology and its development prospect in china.

Key word:Technology of water treatment Method Future development The present situation of water resources

建国前三十年，我国实行的是计划经济体制，我国给水排水事业随着整个国民经济的发展而发展，随着我国经济实力的不断提高，相应的对水的需求也加速的增长。然而我国是一个水资源短缺的国家，再加上之前对水资源的浪费和污染，以及污染治理滞后，大量城市污水和工业废水未经处理排入水体使得水资源变得更为稀少。解决我国水危机的方针，应是以水资源的可持续利用支持我国社会经济的可持续发展。为此水污染治理和节水是两个非常重要的环节。

一、我国水资源的现状

我国是世界上十三个水资源严重短缺的国家之一。水资源短缺和水资源分布不均严重地制约着我国经济社会的发展。我国水资源现状主要从以下几个方面简单介绍：

第一，我国虽有水量2.8万亿立方米，但人均水资源仅2300立方米，相当于世界人均的1/4，被列为世界上最贫水的13个国家之一。1998年我国人均水
