Percolate Quality in Soil Cultivated With Application of Wastewater From Swine Slaughterhouse and Dairy Products

Abstract

ABSTRACT:The objective of this study was to evaluate the quality of the percolate in soil columns cultivated with Tiffon-grass 85 under different wastewater rates from swine slaughterhouse and dairy. The experiment was conducted at the Department of Engineering at the Federal University of Lavras, in PVC columns with 0.30 m of diameter and 1.2 m deep, filled with Dark Red Latosol cultivated with Tifton-grass 85. The treatments consisted of a (AQT0) control with recommended chemical fertilization for Tifton-grass 85 (300 kg ha -1 year -1 of N), and four doses of SSW and DPW (100, 200, 300 and 400% of the recommendation) in a CRD with 3 replications. The samples of percolated were collected and characterized weekly. The treatments of highest dosage have obtained COD, after 120 days, of 47.7 mg L -1 (AAT3) and 38.6 mg L -1 (AAT4). Although nitrate concentrations were elevated on the earlier months, the greater assimilation of nutrients by the Tifton-grass 85 and the reduction of the mineralization of organic material resulted in lower nitrate concentrations of 10 mg L -1 .

Optimization of the Coagulation–Flocculation Process for Slaughterhouse Wastewater Using Response Surface Methodology

“…[ 42 ] In some studies, it has been stated that it may be advantageous to use different wastewater sources in pasture irrigation: sewage waste [ 41,43 ] or cattle waste. [ 44 ] In some studies in which slaughterhouse wastewater was used as irrigation water, the quality of the soil in nitrogen percussion [ 45 ] and the phytotoxicity of cucumber and lettuce seeds in the course of germination [ 46 ] were investigated. The soil quality and the properties of sunflower and corn, [ 47 ] pasture, [ 48 ] and hay farming, [ 49 ] which used slaughterhouse wastewater as irrigation water, were also examined.…”

“…Furthermore, 23 institutions were listed within the 29 papers studied in this review (please see supplemental material 1 -Appendix A), suggesting that there is no leading institution studying this topic. Russel, Coorper and Lindsey, 1993Guo and Sims, 2000Churchman and Tate, 1986Balks, Mclay e Harfoot, 1997Adesemoye, Opere and Makinde, 2006Shilpi et al, 2018Magesan et al, 1999Wells and Whiton, 1970Tate, 1973Bole and Gould , 1985Osemwota, 2010De oliveira et al, 2017Russel, 1982Da Silva Neto et al, 2013 By analyzing the bibliographic coupling, which assess the similarity between records from their cited references (Lucas and Garcia-zorita, 2014;Thelwall and Wilkinson, 2004) it is possible to identify that only 8 out of the 29 papers share citations. Records that share citations are from the same authors, and the highest number of shared articles is three, between papers from Oliveira et al (2017a) and Oliveira et al (2017b) (Figure 5).…”
