    摘要： The invention relates to a process for decreasing the contents of iron and manganese in ground water or surface water flowing through an aquifer or through a basin or a filter containing naturally occurring filter material. Water containing oxygen or oxygen-releasing substances is introduced intermittently through a number of injection wells or injection pipes (1-9) arranged around an extraction well or extraction pipe (10) for purified water. During each introduction of oxygen-containing water said water is fed to only some of said injection Wells or pipes (1-9) and simultaneous- . ly water is drawn from nearby, adjacent or intervening injection wells or pipes (1-9).

    摘要： The invention relates to a process for decreasing the content of nitrate in ground water, artificial ground water, that is infiltrated surface water, or sarface water flowing through an aquifer or through a basin or a filter containing naturally occurring filter material. Water containing denitrification organisms and or substrate therefore is introduced intermitterially through a number of injection wells or injection pipes arranged around the or more extraction wells or extraction pipes for purified water. During each introduction of water containing denitrification organisms and/or substrate therfore said water is fed to only some of said injection welle or pipes and simultaneously water is drawn from nearby, adjacent or intervening injection wells or pipes or the purpose of creating a denitrification zone at a distance suficiently far from the extraction well or extraction pipe.

    摘要翻译： 本发明涉及一种减少地下水，人造地下水，即渗透的地表水或流过含水层或通过盆地的表面水或含有天然存在的过滤材料的过滤器的硝酸盐含量的方法。 因此，含水脱氮生物体和/或底物通过围绕一个或多个提取井排列的许多注入井或注入管或用于净化水的提取管间歇地引入。 在每次引入含有反硝化生物体的水和/或底物期间，因此所述水仅被供给到一些所述注入井或管道中，并且同时从邻近的，相邻的或介入的注入井或管道中抽出水，或者将产生脱氮区的目的 距离提取井或提取管足够远的距离。

    摘要： Wastewater containing nitrate and/or nitrite is purified by passing said water, in a first stage, under reducing conditions through a basin or a filter containing naturally occurring filter material. The reduced water is then oxygenated in a second stage and kept in a basin until the oxidation processes are completed.
