Among the economic crops, pachyrhizus leaf had the most remarkable treating effect, the COD treating capacity per day per unit area was 4.01g, that is, a 50% treating rate; the BOD treating capacity was 1.15 g, that is, a 35% treating rate; the TP treating capacity was 0.23 g, that is, a 16% treating rate; the TN treating capacity was 1.87 g, that is, a 74% treating rate; however, the treating effect decreased as the total amount of pollution entering this system increased by raising the water volume, which was mainly owing to the relatively short hydraulic retention time.

由水质试验结果显示，本系统所选用的作物处理生活污水成效极佳，优於一般湿地选用的植物，以及河滩地原生草种型态，其中以地瓜叶的处理成效最为显著，每日单位面积COD去除速率为4.01 g 、处理效率达50﹪；BOD去除速率为1.15 g 、处理效率达35﹪；TP去除速率为0.23 g 、处理效率达16﹪；TN去除速率为1.87 g 、处理效率74﹪，而以加大水量的方式，增加进入本系统之污染总量，其处理成效减低，主要原因受到水力停留时间较短影响，未来可以增加处理面积、水力停留时间加长、提高原水浓度为后续之研究方向，以达到增加本系统处理成效之目的。

For landfill of Jinqianpu, if peripheral zone of yard is consisted of mild clay the longest transportation distances of CODcr and NH4+ are 56.5m and 25.75m respectively in the time limit of landfill stabilization;(5)The optimal dilution ratio of groundwater runoff volume and leachate is 7:1 to meet more over Ⅲ groundwater quality standard(GB/T14848-93);(6)To build numerical model. Using CL- as a simulation factor, the expansion with time of pollution plume was simulatively calculated when the concentration of CL- is 5000mg/L and 2000mg/L in Jinqianpu landfill by means of internationally general simulating software FEFLOW.

就金钱堡填埋场而言，若场地周围为试验亚粘土层，则在填埋场稳定化年限内和的最大迁移距离分别为56.5m和25.75m；（5）垃圾渗滤液与地下水混合稀释后地下水能够达到III类水质标准以上的混合比为地下水径流量与垃圾渗滤液入渗量之比为7：1；（6）建立污染质运移的数值模型，以为模拟因子，利用国际上通用的模拟软件FEFLOW模拟计算了金钱堡垃圾填埋场中浓度分别为5000mg/L和2000mg/L时在一系列年份对地下水污染晕的扩展。

Crude death rate is 201.55 per 100 thousand, and standardization is 184.04 per 100 thousand, which is 43.93% higher than the average level of the whole country. The standardization are as follows: hepatoma (53.57 per 100 thousand), lung cancer (47.76 per 100 thousand), gastric cancer (31.17 per 100 thousand), breast carcinoma (5.18 per 100 thousand), colorectal cancer (8.6 per 100 thousand). Monitoring indicates that the aggravation of water, atmosphere, small marine products, and the unhealth life habits are the main facts. Earlier screening profits diagnosis and prevention beforehand.

结果 慈溪市近十年恶性肿瘤死亡率逐年上升，位全死因的第一位，粗死亡率为201.55/10万，标化死亡率184.04/10万，比全国平均高43.93%，恶性肿瘤顺位及标化死亡率以肝癌(53.57/10万)、肺癌(47.76/10万)、胃癌(31.17/10万)、乳腺癌(5.18/10万)、结直肠癌(8.6/10万)，大气、水、土壤、蔬菜、小海产品监测表明：水质、环境的恶化及本市区域的大气、小海产品局部污染和不良卫生习惯是恶性肿瘤发生的主因，早期筛查利于早发现、早预防。

Due to industry "Three Waste" and living waste material unrational discharge, it made ground water pullution fairly serious.

也就是说，地下水的污染必须具备两个条件：一是由于人类活动引起；二是使水质发生了不利于人和生物正常生存和发展的变化。
