of available technologies for the purification of wastewater in small ponlaciones more degree of implanting is having worldwide is known as Artificial Wetlands. This thesis develops

research on them in the study covering the following general objectives:

- deepen the study of the behavior of different types of Artificial Wetlands applied to the purification of urban waste water

- evaluate the feasibility of different combinations of Constructed Wetlands in order to improve purification yields

- establish the optimum operating range of different types and combinations of Constructed Wetlands for compliance with the regulations of discharges
