Embodiment 1

[0054] see figure 1 As shown, a method for in-situ removal of iron, manganese and ammonia nitrogen in groundwater provided by the embodiments of the present invention includes:

[0055] Step 101: the groundwater in the aquifer flows into the in-situ well located underground;

[0056] Step 102: In the in-situ well, sequentially remove iron, manganese and ammonia nitrogen from the groundwater flowing into the in-situ well;

[0057] Step 103: judging whether the groundwater after removal of iron, manganese and ammonia nitrogen satisfies the preset water quality index, and if the preset water quality index is met, store the groundwater in the water storage area of ​​the in-situ well.

[0058] In the method for removing iron, manganese and ammonia nitrogen in groundwater in situ described in the embodiments of the present invention, the groundwater in the aquifer flows into the underground in-situ well in a natural state, and in the in-situ well, the iron, manganese and ammonia nitr...

Abstract

The invention provides a method for in-situ removal of iron, manganese and ammonia nitrogen in underground water and an in-situ well design method. Through the method, iron, manganese and ammonia nitrogen in the underground water can be removed in situ, and the underground water does not need to be pumped out of the ground surface for ectopic treatment. The method for in-situ removal of iron, manganese and ammonia nitrogen in the underground water comprises the steps that the underground water in an aquifer flows into an in-situ well located underground; in the in-situ well, iron, manganese and ammonia nitrogen in the underground water flowing into the in-situ well are removed in sequence; whether the underground water without iron, manganese and ammonia nitrogen meets a preset water quality index or not is judged, and if the underground water meets the preset water quality index, the underground water is stored in a water storage area of the in-situ well. The methods are suitable for the technical field of underground water purification.

Description

technical field [0001] The invention relates to the technical field of groundwater purification, in particular to a method for in-situ removal of iron, manganese and ammonia nitrogen in groundwater and an in-situ well design method. Background technique [0002] In recent years, through the analysis of the chemical characteristics of groundwater in Northeast my country, it can be known that iron (for example, Fe 2+ ), manganese (for example, Mn 2+ ) and ammonia nitrogen (for example, NH 4+ -N) The phenomenon that the content exceeds the standard. Studies have shown that Fe 2+ , Mn 2+ can be removed in the same layer; however, when the water contains NH 4+ -N, due to the difference in redox potential, Mn 2+ The biological oxidation can only occur in NH 4+ After the complete nitrification of -N, it will react to Mn 2+ has a direct impact on the biological removal of Mn, but when the ammonia nitrogen content is below 2mg / L, it has 2+ Bioremoval has no effect. In addit...
