生物生態(tài)技術在治理農村水體污染中的應用研究
發(fā)布時間：2021-10-22 15:34
有限的水資源和確保清潔水的獲得使世界面臨嚴峻的環(huán)境挑戰(zhàn)。在高度工業(yè)化的國家,如中國,水污染率很高,導致人類消費所需的淡水不足。在這方面,大規(guī)模集中的廢水處理系統(tǒng)被認為是高度工業(yè)化國家的特征,并且長期以來被認為是廢水處理中非常成功的方法。盡管在中國大規(guī)模的廢水處理系統(tǒng)十分普遍,但該國仍然繼續(xù)遭受淡水短缺和水資源惡化的影響。特別是,農村生活廢水已成為淡水水體污染的重要來源。本論文建立了耦合生物單位（厭氧折流板反應器,缺氧池和好氧單元,A2O）和生態(tài)單位（平流人工濕地）的改良生物生態(tài)A2O-人工濕地系統(tǒng),并確定了該系統(tǒng)的關鍵性能指標。本論文研究了不同季節(jié)（夏季,春季,秋季和冬季）下ABR（厭氧折流板反應器）的性能和特性。ABR實現的COD去除效率分別為74%（夏季）,68%（春/秋季）,62%（冬季）。在整個研究期間,室Ⅰ,Ⅱ和Ⅲ顯示出高的COD去除率。在較低的OLR（有機負荷）下,COD去除率高。在所有季節(jié),沼氣產量隨著HRT（水力停留時間）的增加呈下降趨勢。與其它隔室相比,隔室Ⅰ中VFA（揮發(fā)性脂肪酸）的合成較明顯。ABR仍有達到更高效率的潛力,并適用于所有類型的季節(jié)和溫度條件。對A2/...
