摘要
水库作为城市的主要供水水源意义重大,近年来不断出现的富营养化及水质恶化等问题,使水源水库水质污染控制技术研究成为城市供水领域研究的热点课题。回顾了水源水库的水质问题。介绍了内源污染及突发性或周期性高强度水质污染研究方法和结论,并分析了其合理性。将现有的混合充氧技术、扬水曝气技术、上覆水中N、P、有机物生物去除方法及污染沉积物修复方法进行了对比分析。指出了目前该研究领域存在的问题,并对未来研究重点及发展趋势作了进一步展望。
Source water reservoir plays an important role in urban water supply, and the eutrophication and other water quality problems are increasingly serious in recent years. The controlling mechanics and technology for source water reservoir quality becomes a hot research topic. In this paper, the advances in the study of water quali- ty problems of source water reservoir are reviewed. The investigation methodology and conclusion on endogenous pollution, high-intensity pollution of emergency and periodicity are introduced, and the rationality of these investi- gations is discussed. Main water quality restoration techniques are presented and compared, including the tech- nique of mixing aeration, water-lifting aeration, the bio-removing method of the nitrogen, phosphorus and organic matter in the superjacent waters and the restoration method of polluted sediment. At last, the problems and attentions in the relative research are analyzed and the priority research area and tendency in the future are proposed.
