Title: Performance Evaluation of Biota Filter Wall Technology in the Treatment of Black and Odorous Water Bodies
Abstract:
Black and odorous water bodies, caused by organic pollutants and anaerobic conditions, have become a severe environmental problem worldwide. Traditional treatment methods have limitations in effectively removing the pollutants and reducing the odorous smell. As a sustainable and eco-friendly solution, biota filter wall technology has emerged as a promising approach. This study aims to investigate the performance of biota filter wall technology in the treatment of black and odorous water bodies. The study includes a thorough review of the technology, its mechanisms, and its applications. Additionally, field experiments and laboratory tests were conducted to evaluate the performance of the biota filter wall technology in terms of pollutant removal efficiency, reduction of odorous compounds, and improvement of water quality. The results of this research provide crucial insights into the effectiveness of biota filter wall technology and demonstrate its potential as an innovative solution for black and odorous water bodies' remediation.

1. Introduction
Background
Black and odorous water bodies refer to water bodies, such as rivers, lakes, and ponds, that exhibit a dark and unpleasant smell due to the accumulation of organic pollutants and anaerobic conditions. This phenomenon not only poses significant environmental threats but also affects aquatic ecosystems and human health. Traditional treatment methods, including mechanical aeration, chemical dosing, and physical separation, have limitations in effectively removing the organic pollutants and reducing the odorous odor. As a result, there is an urgent need for innovative and sustainable solutions to address this environmental issue.
Problem Statement
