摘要
The invention provides a groundwater and anti-fouling device and method for preventing groundwater from polluting groundwater and reducing the concentration of arsenic in groundwater, and a groundwater channel for reducing the concentration of arsenic in groundwater according to the invention. A device for preventing and controlling arsenic contamination of groundwater harvested during the expedition.In the arsenic contamination device of irrigation groundwater,Weathered strata.Pipeline holes penetrating rock and weak layers;Lesson 2In the upper gas tunnel, including the first card and the boundary of weathered strata and strata mentioned above,In the upper gas tunnel, the second card is installed between the rising stratum and the weak stratum.Wow.In order to prevent the collapse of the part formed by the windward pipeline tunnel, the part passing through the weathered rock stratum is located in the windward pipeline tunnel.Lesson 2Through the part of the above-mentioned pipe hole, a pipeline is formed which can inject the injected substance.In the above-mentioned through pipe, in the field of rock formation, the injection or the first hole supplying cement can be sprayed.A loose part is formed in the above-mentioned strata and flows through the groundwater of the upper strata.The algebraic layers that make up the above layers may be phosphate coatings.
