1、水污染污染源及其综合治理Water Pollution Source and Comprehensive ManagementI水污染污染源及其综合治理摘要:水是一种重要的自然资源和战略储备,目前中国的用水量已超过美国成为世界第一大用水国,但中国存在着水资源分布不均、利用率低、人均占有量少、水污染严重等特点，因此怎样合理的防治水污染就成为了我国面临的一个关乎人民生活和国家可持续发展的重要课题。本文主要结合中国水资源的现状并借鉴国外水污染治理的先进方法分析了我国水污染的主要特征和治理方案。本文共分五章，首先介绍了世界水资源的和我国水资源的特征，接着介绍了水污染的污染源及其分类，最后按照工业水污染
2、、农业水污染、城市水污染的分类方法介绍了各自的主要水污染源和处理方法。工业污水处理方面，主要讲了污水处理的物理方法、化学方法、物理化学方法；农业污水处理方面，主要分析了化肥和农药对水的污染和我国农村水污染的成因和防治现状；城市水污染方面，主要涉及了城市水资源的特征和城市水资源的再利用技术。总结前人经验，促使人们了解国内外水资源状况，了解目前污水处理再利用方法，推过新技术，新方法，新工艺，提高人们的环保意识，保护水资源，是本文的主要宗旨。相信随着科学技术的发展和各种新技术在污水处理方面的应用，我国在水污染治理和综合利用方面一定会取得更好的发展，真正实现可持续发展和谐发展。关键词：水污染；工业污水
