該方案由4個工程子系統組成， （ 1 ）截污工程：在岸丘橋和南州橋位置各築一節制閘（而岸丘橋工程又是首選工程） ，以封住湖泊兩頭入流，杜絕污染物進入水源地的截污工程； （ 2 ）引水工程：是截污工程的配套工程，利用下游長蕩湖來補充水量，並對3個引水工程設想進行了系統分析，推薦涵管方案，同時將長蕩湖作為該市戰略水源地一併納入保護體系中； （ 3 ）濕地生態處理工程：對進入蕩區前的蘆葦區進行綜合整治，發展以蘆葦為主的濕地生態處理工程； （ 4 ）環湖綠色自然保護帶工程：包括建設圍湖蘆葦蕩、環湖林帶、綠色食品基地以及污泥處置。The paper studied three aspects of extracelluar enzymes in sediments of the tidal flat wetland, namely 1 ) the distibution of five sorts of extracellular enzymes in sediments in the east end of chongming island along the elevation gradient or community succession series, the relationships between the activities of enzymes and the ecological factors, and functions of extracellular enzymes in the process of community succession ; 2 ) the effects of the heavy metal ions and edta on the activity of alkaline phosphatase in sediments of the east end of chongming island by adding and removing of heavy metal ions, discussing whether the activities of extracellular enzymes could be taken as the indicators for the environmental status ; 3 ) the variations of the activities of extracellular enzymes in sediments in the east end of hengsha island after the discarding clay
本文以長江口典型濕地?崇明東灘為例，首次研究了沿高程梯度或沿植被演替系列沉積物中堿性磷酸酶等五種胞外酶活性的空間分佈規律，分析了胞外酶活性與環境因子的相互關系及其產生機制，討論了胞外酶活性在濕地植被演替中的作用。同時以崇明東灘沉積物為對象，運用重金屬離子的添加和去除等方法，研究了重金屬離子對沉積物中堿性磷酸酶活性的影響，利用胞外酶活性的變化探討了崇明東灘重金屬污染的狀況。此外，本文還研究了橫沙東灘吹泥試驗工程對沉積物環境因子和胞外酶活性的影響並進行了對比分析。Nikolay went out on to the wet and muddy steps. there was a smell of decaying leaves and dogs
尼古拉走上被雨淋濕的污泥滿地的臺階，這里發散著枯萎的樹木和獵犬的氣味。Introducing several main dephosphorization methods of wastewater, the paper discussed chemical deposition dephosphorization method, biological dephosphorization method and constructed wetland dephosphorization method in detail and analyzed their advantages and disadvantages : chemical deposition dephosphorization has higher phosphorus removal rate, but it will bring a large mount of sludge ; biological dephosphorization is more convenient for operation, but phosphorus removal rate is lower ; constructed wetland is a low - cost technique to remove phosphorus, but it should be developed
摘要介紹了污水除磷的幾種主要方法，並對化學沉澱法除磷技術和生物除磷技術以及人工濕地除磷技術進行了詳細論途，簡要分析了各種方法的利弊：化學法除磷效率較高，但會產生大量化學污泥；生物法除磷操作簡單，但除磷效率較低；人工濕地除磷技術廉價高效，但有待進一步發展完善。分享友人
