1、《南水北調(diào)與水利科技》:南水北調(diào)東線截污導流尾水綜合處置方案研究(阮曉紅倪利曉萬清華趙振華)(摘要) 摘要:為滿足國家對南水北調(diào)東線工程江蘇段出省水質(zhì)要求,徐州市和宿遷市的處理尾水通過尾水導流工程經(jīng)新沂河入黃海,導流入新沂河尾水量41萬t/d,COD污染負荷達14965t/a,使現(xiàn)狀劣Ⅴ類水體的新沂河更加不堪重負,導致新沂河沿線至入??诟浇K虻纳鷳B(tài)環(huán)境進一步惡化。2550m2人工濕地中試工程實驗結(jié)果表明,濕地床技術(shù)能有效的凈化污染河水,對COD的去除率可達60%—70%,氨氮的去除率達75%—85%;水蔥、春蘭等植物具有較強的耐淹特性。
2、根據(jù)充分利用當?shù)刭Y源、以最小的建設(shè)投資和運行費用達到工程目標的原則,利用新沂河束水型行洪河道具有大量灘地資源特征,優(yōu)化布置人工濕地床進行新沂河污染河水處置工程方案的設(shè)計。
