Abstract

The need for an improvement in the quality of water resources and overall environmental impact it became necessary in singing Rioverde and its urban and rural parishes a study to design a system Wastewater Treatment this in order that the parameters that are outside the norm according TULSMA using suitable methods remain within the maximum allowable. For this the physico-chemical and biological characterization of domestic wastewater was held in the parish Rioverde and identifying certain parameters that must be addressed for the appropriate design which consists of the following elements: roughing through steel grates inclination 45, an artificial wetland subsurface horizontal flow having a surface area of 364,99 m and purification as vegetation Pasto Aleman, the percentage of BOD removal obtained is 73, 87%, 64,58% of COD, 83,33% Detergent, Oils and Fats 65% and fecal and total coliforms exceed 99,9%. Finally water from the artificial wetland through the filters of Upflow Anaerobic to complete the process in the treatment system and validating the design parameters that meet fully the rule of TULSMA which are: BOD 46 mg/L, COD 85 mg/L, Detergent 0,4 mg/L, Oils and Fats 11,2 mg/L and total and fecal coliforms in absentia. Drying beds should be cleaned regularly usually having a humidity of 40% a 30%, once dry, the sludge is removed and discharged to landfills or used as a soil conditioner.
