Using built systems of up / down type wetlands for poultry wastewater treatment.

Abstract

This work aimed to study the laboratory scale prototypes, simulating constructed wetland systems - CWS ascent and descent type, aquatic macrophytes Eichhornia crassipes vegetation and soil aggregates in the treatment of industrial effluents from poultry slaughterhouses corral. Initial characterization of the effluent was carried out to verify their components such as conductivity, salinity, total dissolved solids, total suspended solids, turbidity, nitrite, nitrate, ammonia, sulfur, sulfate, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, total nitrogen and total phosphorus, to set the size, the continuous flow system and the ground. The collections are periodically made in refrigeration FRICOCK Birds Industry and Trade Ltd. to simulate the treatment site. The effluent from this industry was treated in 12 prototypes CWS and analyzed for temperature, pH, OD, STD, conductivity and salinity. Initial results showed tendency toward bigger efficacy of the treatment of the effluent in ascendant system that contains the soil and aquatic weeds.
