In-situ solution monitoring device in vadose zone and ammonia nitrogen enhanced nitrification system and method

Abstract

The invention discloses an in-situ aeration zone solution monitoring device and an in-situ aeration zone ammonia nitrogen enhanced nitration system and method. The in-situ aeration zone solution monitoring device comprises a pump and at least one solution collection pipe (8) arranged in an aeration zone, wherein the solution collection pipe (8) comprises a guide part (13) and a collection part (12) which are arrayed along the axial direction; the collection part (12) is provided with a hollow cavity and through holes are formed in the wall of the collection part (12); and the pump is communicated with the hollow cavity of the collection part (12). The in-situ aeration zone ammonia nitrogen enhanced nitration system comprises a first operation well (1) adjacent to a garbage body (6) in the aeration zone and the in-situ aeration zone solution monitoring device; and at least one water distribution pipe (3) is arranged from the well wall of the first operation well (1) to the garbage body (6). By virtue of in-situ monitoring on an aeration zone solution, an ammonia nitrogen nitration effect in the aeration zone can be accurately monitored under the condition that the structure of the aeration zone is not damaged.

Description

technical field [0001] The invention relates to the restoration of polluted vadose zone and groundwater protection technology, and more specifically relates to an in-situ solution monitoring device and method for the vadose zone, and an in-situ ammonia nitrogen enhanced nitrification system and method for the vadose zone. 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 am...

Problems solved by technology

[0004] Therefore, researchers have proposed many technologies to promote the nitrification of groundwater ammonia nitrogen in response to the above problems. However, monitoring the effect of ammonia nitrogen nitrification in the vadose zone is still a big problem in these technologies.
