Embodiment Construction

[0068] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0069] It should be noted that, from top to bottom, the strata are the vadose zone and the saturated zone (groundwater layer). In addition, the area where the garbage body is located and near the garbage body is dominated by ammonia nitrogen pollution, which is an ammonia nitrogen pollution area. The groundwater in the peripheral area of ​​the ammonia nitrogen pollution area is mainly polluted by nitrate nitrogen, and this peripheral area is the groundwater nitrate nitrogen pollution area. The "groundwater nitrate nitrogen polluted area around the garbage body 6" in the present invention refers to the groundwater nitrate nitrogen polluted area around the ammoni...

Abstract

The invention discloses a groundwater ammonia-nitrogen in-situ enhanced nitrification and denitrification integrated system and method. The integrated system comprises an ammonia-nitrogen in-situ enhanced nitrification system, a nitrate-nitrogen in-situ enhanced denitrification system and an in-situ solution monitoring device in an aeration zone. The ammonia-nitrogen in-situ enhanced nitrification system comprises a first operating well and a water distribution pipe, wherein the first operating well is adjacent to wastes in the aeration zone, and the water distribution pipe extends to a position below the wastes to wet the lower part of the aeration zone. The nitrate-nitrogen in-situ enhanced denitrification system comprises a water pumping well, a static mixer and a water injecting well, wherein the water pumping well and the water injecting well are both arranged in a groundwater nitrate-nitrogen pollution zone around the wastes. The groundwater and the carbon-source agent are injected into the water injecting well after being mixed uniformly in the static mixer. The in-situ solution monitoring device in the aeration zone comprises a pump and at least one solution collecting pipe, wherein the solution collecting pipe is arranged in the aeration zone. By adopting the technical scheme of the invention, a very good groundwater pollution remediation effect can be achieved, and the current situation of severe water pollution of China can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of groundwater pollution remediation, in particular to biological treatment technology, and more specifically to an integrated system and method for in-situ enhanced nitrification and denitrification of groundwater ammonia nitrogen. Background technique [0002] The accumulation of solid waste (garbage body) such as domestic garbage and industrial waste in daily life will produce a large amount of ammonia nitrogen, but there is currently no technology to solve this problem, causing ammonia nitrogen to gradually infiltrate into the soil, causing soil pollution, and at the same time affecting the surrounding groundwater. pose a certain degree of pollution threat. [0003] The form of pollution in natural surface water and groundwater is mainly nitrate nitrogen, including nitrogen in the form of free ammonia and ammonium ions, while ammonia nitrogen in polluted water is called hydrated ammonia, also known as no...
