水污染

For society and mankind but durative development, our country is in " 15 " during plan to throw 270 billion RMB to control water pollution, among them one important is river, river, laky processing, and the agent killing alga that its processing technique is a tradition more again, heavy alga agent, garrulous coagulates the method such as the dredge that agent and whole nation use generally, confirm through practice, afore-mentioned methods cannot administer the pollution of river, lake effectively not only, and often accentuate or transfer water pollution 2 times.

为了社会和人类的可持续性发展，我国在&十五&期间拟投入2700亿人民币控制水污染，其中重要的一项就是江、河、湖泊的治理，而其处理方法又多为传统的杀藻剂、沉藻剂、絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂及全国普遍采用的疏浚等方法，经过实践证实，上述方法不仅不能有效地治理河、湖的污染，而且往往加重或二次转移水污染。

Panyue, the deputy of Ministrator of Eniveronment Protection disclosed to the press that facing the severe water pollution, Ministration of Eniveronment Protection will conduct "Examination and Approval of Valley" in 6 cities, 2 counties and 5 industry parks which water pollution and nonabservance are severe in Yangtze River, Yellow River, Hui River and Hai River.

环保总局副局长潘岳今日向新闻界通报，针对中国当前严峻的水污染形势，环保总局自即日起对长江、黄河、淮河、海河四大流域部分水污染严重、环境违法问题突出的6市2县5个工业园区实行&流域限批&；对流域内 32家重污染企业及6家污水处理厂实行&挂牌督办&。

We have initially found some legal systems of solving water pollution dispute,but our water pollution dispute legal system,on the whole,is still unperfected,and the revolution efficiency is not high.

我国已经初步建立起解决水污染纠纷的法律制度，但总体上讲，我国水污染纠纷法律制度还相当不完善，处理效率也不高。

On the basis of solute transport theory, the coal gangue eluviated in Xinqiu in Fuxin coal miming area was studied for the pollution of groundwater. The mechanism of coal gangue eluviated in the aquifer was analyzed. A coupled numerical model was developed with convection、sorption and dissolve、disintegration for simulating the leachate transport in groundwater. The model was discreted by using a Gelarkin finite-element method and a Picard iteration scheme, and the process of coal gangue leachate was presented, which predict the temporal and spatial distribution features of contaminant concentration. The result indicates that the contaminated plume is continually extended as time increases, and the vertical diffusion is more abvious.

以溶质运移理论为基础，针对阜新市新邱露天煤矿煤矸石淋滤液对地下水污染实际情况，分析了煤矸石渗滤液在含水层中运移的规律，在综合考虑对流扩散、吸附解吸、生物降解条件下建立了淋滤液在地下水中运移的耦合动力学数学模型，采用Galerkin有限元方法和Picard迭代法相结合对耦合模型进行了离散，模拟了淋溶液对地下水污染的动态过程，预测了污染浓度的时空分布特征，并结合实际观测数据进行对比。

Pollution of river basins, organize people to work out plans for

经批准的水污染防治规划是防治水污染的基本依据，规划的修订须经原批准机关的批准。

Therefore, it will help to resolve the water pollution discordance. On the basis of assessing economic loss due to water pollution, this paper employed water environment model to describe the spatial impact of pollutant discharge in rivers. In consideration of the environmental and economic effects of pollutant discharge, a theoretical model for water pollution compensation in rivers was proposed, with its basic characteristics, processing methods and application conditions discussed in the paper.

在水污染经济损失评估的基础上，以河流为研究对象，采用水环境数学模型的方法描述了污染物排放的空间影响关系，进而把超量排放的环境影响与经济影响联系起来，对模型的基本特征、处理方法和应用范围进行了讨论，并且以太湖流域范围内的京杭运河为例进行实证研究，得到了河流水污染损失补偿的数学模型。

Based on analyzing water pollution controlling and managing technique of national in and out, This paper has done research and requirement analyse on water system structure and managing actuality of The Wei River Shann"Xi sect,, researched water pollution controlling technique of The Wei River (exampling by Xi"An sect),adopted reverse arithmetic from environment goal to polluting fountain improving, viz.

本文在分析国内外水污染控制和管理技术的基础上，通过对渭河陕西段的水系结构、污染和管理现状进行了调查与需求分析，对渭河水污染控制技术进行了研究。

Second, the concentration distributions of solutes in aquifer have relationship with the chemical reaction, such as ion-exchange and precipitation-dissolution.

解决这些问题的关键是在于揭示地下水污染的物理和化学机理，并通过数学手段再现地下水污染过程。

The tracer migration that the tracer concentration continuously injecting into semi-infinite sand column(initialization velocity is zero) and the pollutant continuously enter into aquifer through a discharging well that completely enter into the dive aquifer are two representative groundwater pollution problems ,Then this paper respectively sets above two decided solution problems and the union simulation problem of groundwater and solute as examples, from the question description, the mathematical model selection and determination, the parameters selecting to carry on the value computation, the read-write of attribute data , visualizes by the IDL programs, carries on the numerical simulation and the visualization post-processing to the above groundwater pollution problems, and according to the numerical solution and the solute migration curves, briefly analyzes and predicts the temporal and spatial distribution features and distribution range of contaminant concentration.

然后分别以半无限长沙柱中连续注入示踪剂浓度的运移、污染物通过一完全进入潜水层的排放井连续进入含水层这两个典型地下水污染定解问题及地下水流和水质联合模拟问题为例，从问题描述、数学模型选取确定、参数选取到运用IDL编程进行数值计算、属性数据读写、可视化，对上述地下水污染问题进行数值模拟和可视化的后处理，并根据数值模拟的数值结果和溶质运移曲线，对污染物浓度的分布范围及随时空变化趋势作了简要分析预测。

In order to improve the management of water resource and to prevent water pollution the Law on Prevention and Cure of Water Pollution acted in China.
