A method for treating sewage in a vertical flow constructed wetland sewage treatment system with real-time control and management of nitrification and denitrification denitrification processes

Abstract

The invention discloses a vertical flow constructed wetland sewage treatment system and a method thereof for real-time control and management of nitrification and denitrification denitrification processes. The treatment system includes a vertical flow constructed wetland subsystem and a dynamic data acquisition subsystem; the vertical flow The constructed wetland subsystem includes wetland matrix and wetland plants; the vertical flow constructed wetland subsystem is provided with an adjustable water outlet connected to the bottom and higher than the bottom; the dynamic data collection subsystem includes The detection part in the middle of the matrix and the analysis part electrically connected with the detection part. The vertical flow constructed wetland sewage treatment system provided by the present invention can monitor the NH in the vertical flow constructed wetland system in real time 4 + -N, NO 3 ‑ ‑N concentration changes and water quality conditions such as DO, pH, and Eh can be used to adjust and respond to the reaction situation in a timely manner based on the basis when treating sewage with complex and variable water quality, improve the removal efficiency of nitrogen pollutants, and maintain The stability of system operation.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to a vertical flow artificial wetland sewage treatment system and a method thereof for real-time control and management of nitrification and denitrification denitrification processes. Background technique [0002] Constructed wetland technology is an efficient and stable sewage treatment technology. The removal rate of pollutants such as BOD, COD, SS and polluting bacteria in sewage can generally reach more than 90%. However, due to the aerobic and Due to the requirements of anaerobic environment, the removal efficiency of nitrogen is low and unstable, and the research on the nitrogen removal efficiency of constructed wetlands has always attracted much attention. [0003] The traditional water quality monitoring method is limited by the monitoring frequency and cannot timely and accurately reflect the change process of water quality pollution. The changes in...
