PHYTOREMEDIATION THROUGH THE PALUSTRE AND FLOATING SPECIES, Zantedeschia aethiopica AND Eichhornia crassipes IN THE TREATMENT OF DOMESTIC WASTEWATER IN THE AREA OF THE NATURAL REGION QUECHUA-CAJAMARCA

Abstract

The purpose of the research was to evaluate the efficiency of the phytoremediation system by means of the palustre (Zantedeschia aethiopica) and floating (Eichhornia crassipes) species in the treatment of domestic wastewater in the natural Quechua-Cajamarca region, for which the catchment point was located and the location of the project, the treatment system was subsequently designed and implemented considering infiltrations in the horizontal subsurface wetland that contained the substrate, the water to be treated, the Zantedeschia aethiopica species with the measures (width = 1.16 m, length = 2.32 m, height = 0.5 m) followed by the surface wetland composed of the water to be treated and the species Eichhornia crassipes (width = 1.39 m, length = 2.78 m, height = 0.40 m). The treatment lasted 90 days, then the physicochemical and microbiological parameters were monitored at the entry and exit whose removal results gave Oils and fats 76%, BOD₅ 95%, COD 92%, SST 95%, turbidity 96%, N-NH3 64%, Conductivity 59%, and the lowest values ​​were Color 34% and CTT 22%. In the analysis, the LMP that did not meet only was CTT and the others did, however for the RCTs they met Oils and Fats, Color, Conductivity, temperature, pH, SST, turbidity, and those that did not meet N-NH3, BOD5, COD, OD and CTT. In conclusion, 70% removal efficiency was reached, the parameters that failed to achieve adequate removal to comply with the LMP and ECA completely indicate the need to implement a primary treatment.
