生物生态技术在治理农村水体污染中的应用研究
发布时间：2021-10-22 15:34
有限的水资源和确保清洁水的获得使世界面临严峻的环境挑战。在高度工业化的国家,如中国,水污染率很高,导致人类消费所需的淡水不足。在这方面,大规模集中的废水处理系统被认为是高度工业化国家的特征,并且长期以来被认为是废水处理中非常成功的方法。尽管在中国大规模的废水处理系统十分普遍,但该国仍然继续遭受淡水短缺和水资源恶化的影响。特别是,农村生活废水已成为淡水水体污染的重要来源。本论文建立了耦合生物单位（厌氧折流板反应器,缺氧池和好氧单元,A2O）和生态单位（平流人工湿地）的改良生物生态A2O-人工湿地系统,并确定了该系统的关键性能指标。本论文研究了不同季节（夏季,春季,秋季和冬季）下ABR（厌氧折流板反应器）的性能和特性。ABR实现的COD去除效率分别为74%（夏季）,68%（春/秋季）,62%（冬季）。在整个研究期间,室Ⅰ,Ⅱ和Ⅲ显示出高的COD去除率。在较低的OLR（有机负荷）下,COD去除率高。在所有季节,沼气产量随着HRT（水力停留时间）的增加呈下降趋势。与其它隔室相比,隔室Ⅰ中VFA（挥发性脂肪酸）的合成较明显。ABR仍有达到更高效率的潜力,并适用于所有类型的季节和温度条件。对A2/...
