At the same time the study analyse the structural system of the index and it ' s weight with the ahp, and choose soil quality, soil thickness, the content of organic matter, terrain, elevation and the ration of irrigated guarantee as gradation index and choose soil quality, soil thickness, the content of organic matter, terrain, elevation, the ration of irrigated guarantee, the condition of traffic, the distance from the central city, the scatter degree of field, the neat degree of field, loss of water and erosion of soil and land contamination as classification index. at the same time the study emphasize the effect of the condition of ecological condition and environmental contamination
採用層次分析法對該區域農用地分等定級的指標體系及其權重進行了研究,選擇表層質地、土層厚度、有機質含量、地形、海拔、灌溉保證率等6項指標參與分等評價,選取表層質地、土層厚度、有機質含量、地形、海拔、灌溉保證率、對外交通狀況、距市中心距離、田間道路狀況、田塊分散度、地面平整度、水土流失、土地污染等13個因子分指標區進行定級評價,強調了生態條件及其環境污染狀況在農用地分等定級中的作用。Moreover, the drilling process needs to be refined so that the deeper aquifers are not poisoned by arsenic - bearing water trickling down from the shallow aquifers through the boreholes themselves
還有,鉆孔的過程必須要改良,較淺含水層中的砷才不會經由鑿孔向下蔓延,進而污染了較深的含水層。In the article, considering the potentially severe pollution of the subsurface environment from the low level radioactive waste, the dynamic integrated transport model of low level nuclide in vadose and saturate zones has been established and is used to predict the dynamic action of the nuclide in a disposition spot
摘要針對處置庫中低中放核素釋放對地下環境潛在性污染的嚴重性,建立了核素在包氣帶和含水層中聯合遷移的數值模型,利用所建立模型對某一處置場核素遷移的動力學行為進行環境預測。The results show that the main pollutants are ss and cod, and it is effective to treat the wastewater by manmade suspended layer process, and the quality of filtered water is satisfied with the standard
結果表明,加工海帶時正常排放廢水的主要污染物是懸浮物( ss ) , cod含量也超過了排放標準,採用人工懸浮層工藝處理海帶廢水的效果較好,過濾后的水質基本可以滿足排放標準。It is conclude that systematic coupling numerical model is an effective method to study the nuclide transport in vadose and saturate zones and can offer scientific evidence and technique guide for the safe disposition of nuclide waste and environmental assessment
採用系統耦合數學模型來研究核素在包氣帶和含水層中的運移是預測核素污染的重要手段和有效方法,可為核素在地下處置庫中安全處置及環境影響的評價提供科學依據和技術指導。Article 42 at places where no satisfactory impervious strata exist, enterprises and institutions shall be forbidden to use ditches, pits or ponds devoid of safeguards against seepage for conveyance or storage of waste water containing toxic pollutants or pathogens, or of other wastes
第四十二條在無良好隔滲地層,禁止企業事業單位使用無防止滲漏措施的溝渠、坑塘等輸送或者存貯含有毒污染物的廢水、含病原體的污水和其他廢棄物。Recycling the collected leachate to landfill can raise the ratio of containing water of garbage, and increase the humidity of garbage, and improve the activity of microbial in garbage, and improve the rate of producing methane, accelerate the decomposition of organic and shorten the stabilization process of landfill
將滲濾液收集,回灌到填埋場可以提高垃圾層的含水率,增加垃圾的濕度,增加垃圾中微生物的活性,加速產甲烷的速率和垃圾中污染物溶出及有機物的分解,縮短填埋場垃圾的穩定化進程。So the risk of inadvertently contaminating the deep aquifers must be carefully weighed
所以,深層含水層意外受污染的風險一定要小心考慮。Compared with the reported pcbs concentrations in sediments of other coastal areas in china and other countries, the level of pcbs pollution in jiaozhou bay was about the average of non - metropolitan cities
總pcbs含量落在國內外海洋近岸表層沉積物含量范圍的中值區。污染來源有城市污水排放及大氣來源兩種,而不屬于工業污染類型。分享友人
