| Summary: | The contamination of water bodies has increased in recent years due to the
lack of wastewater treatment plants due to their high cost of
construction, operation and maintenance. Failure to treat this wastewater is
harmful to the animals that inhabit the bodies of water that receive them, since they
can ingest contaminants. This can later cause diseases in the
people who live near the water currents since sometimes they
They feed on the fish that remain in these channels. Due to the above, it is important
the search for cheaper systems, easier to operate and, above all, affordable for
communities in general. Based on previous experiences, the construction
of a prototype of artificial wetland that allows to improve the quality of the water before being
discharged into the rivers and that can even be used for irrigation of crops and for the consumption of
animals.For the development of this research project, several species of
plants from wetlands and different substrates, which together with microorganisms
work in consortium forming a symbiosis, allowing the reduction and degradation of
wastewater contaminants.
Constructed wetlands use organic components that have a low cost in the
market which decreases the value in the implementation, maintenance and commissioning
gear, which, compared to conventional systems, minimizes the impact on the environment
environment (2009, Romero et al).
The applied methodology consisted of building and implementing a wetland prototype with
synthetic water that simulated domestic wastewater. This water had
previously established components that allowed it to be classified as water
residual. Following this, it was evaluated if the retention times are adequate to obtain
a sufficient reduction of contaminants and that this water at the end of the process can be
reused for field activities.

Based on the development of the research project and being aware of what
entails the maintenance of the artificial wetland, the biggest challenge we faced
exposed is the adaptation of plants to the artificial environment. When working with beings
alive we run the risk that plants will not survive and thrive in the new environment that
has been arranged for them, so it was necessary to also evaluate their individual growth,
the height of the foliage, the number of leaves, the physical appearance and the other parameters that
allow us to identify the physical and food needs necessary for a
good performance in terms of the degradation of contaminants present in the water
synthetic. |
