<b>Efficiency of the treatment system of wastewater at a kennel

Abstract: Abandoned canine on streets have been an increasing issue in the majority of Brazilian cities. In order to decrease this problem, many countries have created kennels, which are unities reserved to shelter dogs. The animal confinements produce a huge amount of solid and liquid waste in concentrated residues. There are only few studies about those residues. The kennel Parque Francisco de Assis, located in the municipality of Lavras, shelter about 400 dogs and it has an individual system of treatment, composed by… Show more

“…The concentrations at the end of the anaerobic treatment were also higher than the maximum concentrations allowed for discharge into the stream (60 mg L -1 BOD and 180 mg L -1 COD), with values of 226 and 172 mg L -1 for BOD and 751 and 616 mg L -1 for COD in A and B systems, respectively, without a signi cant difference (p>0.05) in the comparison of the inlets and outlets of the systems. These ndings justify the need to introduce the subsequent aerobic phase as a post-treatment, as already observed by Souza et al (2018). The removal e ciencies of A system were higher than those of B system, not only for organic matter but also for solids and nutrients.…”

“…Figure 2p, q, r, s, t, and u shows a frequent increase in the concentration of nutrients from the anaerobic units (P2A and P2B) due to the accumulation of the mineralized nutrient fraction in the sludge of the ST-ANF system, which undergoes dragging due to hydraulic load shocks or ows into the system, as demonstrated by Souza et al (2018). In this sense, the TKN concentrations at the outlet of the anaerobic systems did not meet the legal requirement, with 46 and 29 mg L -1 in A and B systems, respectively, although the law establishes a limit only for ammonia-N, of 20 mg L -1 .…”

“…Canis desempenham importante função sanitária e de saúde pública. Estes abrigos de cães contribuem para controle da população de animais abandonados e disseminação de zoonoses (SOUZA et al, 2018). Porém, todo abrigo ou lugar destinado ao alojamento e cria de cães possuem aspectos ambientais, os quais sem controle adequado podem causar variados impactos ambientais, como contaminação do solo, da atmosfera, dos rios e águas subterrâneas; além de causar danos à saúde de seus trabalhadores e à população localizada em seu entorno.…”
