    • This invention has three parts: Part 1 Two-phase extraction of contaminated water and vapor from extraction wells using drop tubes with vertical slots or orifices; Part 2, Separation of extracted water and vapor/air at the wellhead or in a common manifold installed in ground, Part 3 injection of the extracted water using injection well with a drop tube similar to drop tube in the extraction well without the orifices or slots that extend above and below the water table. This invention strips volatile organic compounds from water, creates a recirculation cell in subsurface, increases biodegradation of organic compounds within the recirculation zone. This inventions also facilitate performing enhanced in-situ bioremediation or chemical oxidation by adding oxidation chemicals or bioremediation substance into the injection stream.
    • 本发明有三个部分:第1部分使用具有垂直槽或孔的滴管从萃取井中两相萃取污染的水和蒸气; 第2部分:在井口或安装在地面上的普通歧管中分离提取的水和蒸汽/空气,第3部分使用注射井注射提取的水,并将滴管与类似于放液管的滴管在没有孔或槽的情况下 在水面上方和下方延伸。 本发明从水中分离挥发性有机化合物,在地下产生再循环细胞,增加再循环区内有机化合物的生物降解。 本发明还通过将氧化化学品或生物修复物质添加到注射流中来促进进行增强的原位生物修复或化学氧化。

    • The invention concerns a procedure for drawing water from a ground water store in such manner that the water obtained will contain the least possible amount of iron or manganese compounds, of hardness-inducing salts or of other detrimental impurities occurring in the ground water. The procedure is intended for use in those cases commonly encountered in practice where there is stratification in the occurrence of impurities in the ground water, and according to it at least two separate lifting pipes are inserted in the soil in different layers in accordance with the way in which the contents of impurities vary in different layers. From the lifting pipes water of different quality is then obtained, and the invention implies that water is simultaneously drawn with both lifting pipes, but only the water from that lifting pipe is conducted to normal consumption which is of better quality. The significance of the lifting of inferior quality water lies therein that thereby is reduced the water mixing between different layers, whereby the quality of the water conducted to consumption is constantly good.
    • 本发明涉及一种从地下水储存室抽取水的方法,使得所获得的水含有尽可能少量的铁或锰化合物,硬度诱导盐或在地下水中发生的其它有害杂质。 该程序旨在用于在实践中通常遇到的在地下水中杂质发生分层的情况下通常遇到的情况,并且根据其中至少两个单独的提升管根据方式插入不同层中的土壤中 其中杂质含量在不同层次上变化。 从提升管中获得不同质量的水,本发明意味着同时用两个起重管抽水,但只有来自该起重管的水才能进行正常消耗,质量较好。 提供劣质水的意义在于其中,由此减少了不同层之间的水混合,由此进行消耗的水的质量持续良好。
