- Abstract
Objective: To analyze available information about constructed wetlands and to identify the design, substrate, and vegetation advantages that could be an alternative solution to pig production system wastewaters. Design/methodology/approach: A broad literature review was conducted to identify the main characteristics of constructed wetlands (CWs), as well as the various plant species associated with these systems, and the substrates used as filter beds. Results: Vertical CWs have provided the best organic matter removal results, estimated indirectly through chemical oxygen demand (COD) and nitrogen derivatives such as total nitrogen (TN), ammonium (NH3), nitrate NO3 - (), and nitrite NO2 - (). Several substrates are used as filter beds, but they must be evaluated according to their availability, cost, and feasibility for colonization by nitrifying and denitrifying bacteria to degrade the dissolved pollutants. Combinations of plant species can reduce more than 10% of nitrogen products and organic matter. Study limitations/implications: The lack of monitoring for the satisfactory application of water care standards by small backyard and transition producers limits the adoption of environmental technologies for livestock sustainability in Mexico. Findings/conclusions: Constructed wetlands are inexpensive, easy-to-use, adaptive systems that can be feasible alternatives for reducing the pollution caused by the swine wastewater generated by backyard producers.
