Resumo: | The search for sustainable environmental processes is primordial for the world and, in semi-arid regions where freshwater resources are scarce, the search for non-conventional alternatives for water use should be intensified. Thus, the objective of this work was to evaluate, under the legal aspects of agricultural reuse and soil quality, the use of treated graywater as a water source for acerola plants cultivated in the Brazilian semiarid region. The study was conducted in the rural area of Juazeiro/Bahia with treated graywater from a family adapted biofilter composed of layers of sawdust, coarse sand, gravel and pebbles. Monthly microbiological and physical-chemical analyses of the graywater and soil analyses were performed. It is concluded that there is a diversity of parameters and limit values that makes the interpretation and legal framework of graywater for irrigation difficult, with no single regulation. The greywater promoted an improvement in the chemical quality of the soil, with a decrease in the availability of Al and an increase in the Ca, Mg and P contents. The reuse of greywater for irrigation met the environmental and sustainability criteria by not being discharged directly into the soil and by being used for a noble purpose such as the irrigation of agricultural crops. However, it is necessary to have a legal regulatory unification at the national level, which establishes standards and guidelines for the practice of graywater reuse. |

Así, el objetivo de este trabajo fue evaluar, bajo los aspectos legales de reutilización agrícola y calidad del suelo, el uso de aguas grises tratadas como fuente de agua para las plantas de acerola cultivadas en la región semiárida brasileña. El estudio se realizó en la zona rural de Juazeiro/Bahia con aguas grises tratadas procedentes de un biofiltro adaptado a la familia y compuesto por capas de serrín, arena gruesa, grava y guijarros. Mensualmente se realizaron análisis microbiológicos y fisicoquímicos de las aguas grises y del suelo. Se concluye que existe una diversidad de parámetros y valores límite que dificultan la interpretación y el marco legal de las aguas grises para el riego, sin que exista una regulación única. Las aguas grises promovieron una mejora de la calidad química del suelo, con una disminución de la disponibilidad de Al y un aumento de los contenidos de Ca, Mg y P. La reutilización de las aguas grises para el riego cumplió con los criterios medioambientales y de sostenibilidad al no verterse directamente en el suelo y utilizarse para un fin noble como es el riego de los cultivos agrícolas. Sin embargo, es necesario establecer una unificación normativa a nivel nacional, que establezca normas y directrices para la práctica de la reutilización de las aguas grises.A busca por processos ambientais sustentáveis é primordial para o mundo e, em regiões semiáridas onde os recursos de água doce são escassos, a busca por alternativas não convencionais de uso da água deve ser intensificada. Assim, objetivou-se com este trabalho avaliar, sob os aspectos legais de reuso agrícola e de alterações da qualidade do solo, o uso de água cinza tratada como fonte hídrica para plantas aceroleiras cultivadas no semiárido brasileiro. O estudo foi realizado na zona rural de Juazeiro, Bahia com água cinza tratada oriunda de biofiltro familiar adaptado, composto por camadas de serragem, areia grossa, brita e seixo rolado. Mensalmente, foram realizadas análises microbiológicas e físico-químicas da água cinza e análises químicas do solo. Verificou-se que há uma diversidade de parâmetros e de valores limites que dificultam a interpretação e o enquadramento legal da água cinza para irrigação, não havendo uma regulação única. A água cinza promoveu a melhoria das propriedades químicas da qualidade do solo, com diminuição na disponibilidade de Al e aumento nos teores de Ca, Mg e P. O reuso da água cinza na irrigação atende a critérios ambientais e de sustentabilidade por não ser lançada diretamente ao solo e por ser utilizada para um fim nobre como a irrigação de cultivo agrícola. No entanto, faz-se mister uma unificação regulatória legal a nível nacional, que estabeleça padrões e diretrizes para a prática do reuso de águas cinzas.Editora Verde2022-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/933010.18378/rvads.v17i3.9330Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 17 No. 3 (2022); 167 - 177Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 17 Núm. 3 (2022); 167 - 177Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 17 n. 3 (2022); 167 - 1771981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/9330/11238Copyright (c) 2022 Carlos Laecio Evangelista Franca et al.info:eu-repo/semantics/openAccessFranca, Carlos Laécio EvangelistaAmorim, Miriam Cleide Cavalcante deOlszevski, NelciBelém, Clérison dos Santos2022-12-31T13:51:00Zoai:ojs.gvaa.com.br:article/9330Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:48.608024Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
