An in-situ repair rod for straight-through river sediment pollution control

Abstract

The invention discloses a straight-through type in-situ remediation rod for river sediment pollution treatment. The invention belongs to the technical field of ecological environmental protection. Anin-situ remediation mode can be adopted. The remediation rod is directly inserted into the river sediment, natural wind is used as source power, and an internal and external isolation magnetic force guiding mode is used to transfer power into the remediation rod. Then, an aeration layer is extruded to release air in the aeration layer. Meanwhile, external air on the water surface is supplemented,the dissolved oxygen level of the river sediment area is continuously increased, therefore, the microbial action in the sediment is obviously improved, and the decomposition treatment on an ammonia nitrogen pollution source is accelerated. Meanwhile, a plurality of micro-nano bubbles can be slowly generated during aeration, the pollution treatment effect of the river sediment is comprehensively promoted by utilizing the enhanced decomposition and biological purification functions of the micro-nano bubbles on organic pollutants, secondary pollution is not easily caused, the treatment cost is relatively low, and the original river ecological environment is hardly influenced.

Description

technical field [0001] The invention relates to the technical field of ecology and environmental protection, and more specifically relates to an in-situ restoration rod for direct-through river sediment pollution control. Background technique [0002] Sediment is the sediment of rivers and lakes and is an important part of natural waters. When the water area is polluted, some pollutants in the water can be stored in the sediment through precipitation or particle adsorption, and released again under appropriate conditions, becoming a secondary pollution source. This pollution is called sediment pollution. [0003] The ammonia nitrogen in the water mainly comes from the initial pollution of nitrogen-containing organic matter in the sewage. When the inland water body begins to be polluted and the situation is serious, the flux of the pollutant concentration decreases, and the pollutants are collected in the sediment of the inland river, and the ammonia nitrogen in the water is ...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used sediment pollution control method is to carry out ex-situ treatment after dredging, which not only has a huge workload and high cost of treatment, but also easily affects the original river ecological environment, especially for the treatment of large-scale river sediment pollution. The economic cost of ex situ processing is clearly enormous
