Disposição do lodo de estação de tratamento de efluentes em solos argilosos no município de Matelândia - PR

Abstract

The study was carried out in Matelândia, in partnership with a food industry of the region, whose main objective was to identify if the use of sludge resulting from the effluent treatment process of this same company may change some chemical characteristics of the soil. Sludge is rich in organic matter, and widely used as a biofertilizer on rural properties. In order to carry out this work, the following methodology was used: soil samples were collected at 15 and 30 cm depth, seven main analyzes were carried out: pH, Aluminum, Phosphorus, CTC, Sum of Bases Exchangeable, Base Saturation and Matter From the results, soil comparison was carried out using sludge generated by flotation with the use of organic coagulant and later the sludge generated by flotation using the chemical PAC. With the right results, it was possible to notice that during the six-month period, there were no major alterations in the soil, but the ideal would be to continue the follow-up with periodic analyzes.
