Summary

Lagoon wastewater treatment plants were enhanced with vertical flow reed beds to improve nitrification and reduce ammonium loads. Oxidation-reduction potential (ORP) effectively monitors reed bed performance for optimal operation.

Area of Science:

  • Environmental Engineering
  • Wastewater Treatment Technologies
  • Ecosystem Engineering

Background:

  • Lagoon systems effectively remove organic pollutants but release high ammonium loads into receiving waters.
  • Nitrification is crucial for reducing ammonium discharge from wastewater treatment plants.
  • Vertical flow reed beds offer a potential solution for enhancing nitrification in existing lagoon systems.

Purpose of the Study:

  • To evaluate the efficiency of a combined lagoon and vertical flow reed bed system for wastewater treatment.
  • To assess the effectiveness of oxidation-reduction potential (ORP) for monitoring and controlling reed bed nitrification processes.
  • To determine the impact of the combined system on key effluent parameters like COD, total nitrogen, and TKN.

Main Methods:

Related Experiment Videos

  • Integration of a vertical flow reed bed into an existing lagoon system.
  • Continuous monitoring of effluent quality, including Chemical Oxygen Demand (COD), Total Nitrogen (N(total)), and Total Kjeldahl Nitrogen (TKN).
  • Real-time measurement of oxidation-reduction potential (ORP) in the reed bed effluent to correlate with nitrification performance.

Main Results:

  • The combined system achieved high removal efficiencies: 97% for COD, 77% for N(total), and 94% for TKN.
  • ORP measurements in the reed bed effluent demonstrated a clear correlation with nitrification performance, oxygen supply, and hydraulic conditions.
  • ORP was identified as a reliable indicator for assessing the operational status and nitrification efficiency of the reed bed.

Conclusions:

  • The combined lagoon and vertical flow reed bed system significantly improves wastewater treatment, particularly in ammonium removal.
  • Oxidation-reduction potential (ORP) serves as an effective tool for real-time monitoring and operational control of reed bed nitrification.
  • Maintaining aerobic conditions, indicated by ORP, is essential for high nitrification rates and preventing reed bed clogging.
