石河子西工业园废水处理方法综述

[摘要]随着水资源的日益紧缺,现代工业的迅速发展和城市人口的增长,生活用水和工业用水急剧增加,用各种方法将污水中所含的污染物分离出来或将其转化为无害物,从而使污水得到净化尤为重要。工业废水中含有各种污染物如合成化学品、染料、有机物、难溶有机物、重金属等,如果没有经过处理就排放到附近水体,将导致受纳水体的生态系统遭到破坏。目前可用于工业废水处理的技术很多,本文对目前常用的工业废水处理方法进行了综述,并进行简单介绍,最后对工业废水处理技术进行展望。

Methods Review of Wastewater Treatment in Shihezi West Industrial Park

Abstract:With the increasing shortage of water resources, the rapid development of modern industry and the growth of urban population, the use of domestic and industrial water has increased dramatically. It is particularly important to purify sewage by separating pollutants from sewage or transforming them into harmless substances by various methods. Industrial wastewater contains a variety of pollutants such as synthetic chemicals, dyes, organic compounds, insoluble organic compounds, heavy metal and so on. If it is not treated, it will be discharged into the nearby water, which will lead to the destruction of the receiving water ecosystem. At present, there are a number of skills that can be used to treat industrial wastewater. In this paper, the commonly used methods of industrial wastewater treatment are reviewed and briefly introduced. Finally, the technology of industrial wastewater treatment is prospected.

Keywords: Industrial wastewater; Treatment technology;Recycling

1前言

随着城市工业成产的发展,城市人口的递减,城市规模的扩大,工业废水和生活污水排放出量日益增多,大量未经处理的污水直接排入周围河流,致使城市周围环境污染十分严重,不但直接污染了市区的地下饮用水,而且对河流下游地区的农业成产和人民生活造成了危害,人类和生物赖以生存的生态环境受到了日益严重的威胁。我国工业废水污染现象严重,主要是水体污染。流经全国多个城市的河流有九成以上受到污染,工业企业的废水治理越来越受到重视,尤其对化工、钢铁、有色金属、造纸等行业的污染治理十分迫切。同时,如何提高废水深度处理效率,缓解水资源紧张状况,已成为现在水处理领域研究的重要课题。

同时稳固了所学基础理论和专业知识,进一步提高和训练了工程制图、理论分析、施工方案设计、计算机应用和文献阅读能力。通过毕业设计,使我熟悉有关规范、规程、手册等,为今后独立工作打下基础。
