Description

SISTEMA COMPACTO DE TRATAMENTO DE EFLUENTES EM  COMPACT WASTE TREATMENT SYSTEM IN
TEMPO REAL REAL TIME
CAMPO DA INVENÇÃO FIELD OF INVENTION
A presente invenção descreve um sistema compacto de tratamento de efluentes em tempo real. Mais especificamente compreende um sistema que possibilita o tratamento de efluentes do tipo industrial, doméstico ou misto com tempo de residência do efluente praticamente nulo e sem a produção de odores nem lodo residual.  The present invention describes a compact real-time wastewater treatment system. More specifically, it comprises a system that enables the treatment of industrial, domestic or mixed effluents with practically zero effluent residence time and without the production of odors or residual sludge.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
Esgoto, efluente ou águas servidas são todos os resíduos líquidos provenientes de indústrias e de domicílios e que necessitam de tratamento adequado para que sejam removidas as impurezas e assim possam ser devolvidos à natureza sem causar danos ambientais e à saúde humana.  Sewage, effluent, or wastewater is all liquid waste from industry and households that needs proper treatment to remove impurities and thus be returned to nature without causing environmental damage and human health.
Geralmente a própria natureza possui a capacidade de decompor a matéria orgânica presente nos rios, lagos e no mar. No entanto, no caso dos efluentes, essa matéria em grande quantidade exige um tratamento mais eficaz em uma Estação de Tratamento de Esgoto (ETE) que, basicamente, reproduz a ação da natureza de maneira mais rápida (SPERLING, M. V. - Introdução à Qualidade das Águas e ao Tratamento de Esgotos. 2 ed., rev. Belo Horizonte: UFMG, 1996).  Generally nature itself has the ability to decompose the organic matter present in rivers, lakes and the sea. However, in the case of effluents, this large amount of material requires a more effective treatment in a Sewage Treatment Plant (ETS) that basically reproduces the action of nature faster (SPERLING, MV). Water and Sewage Treatment (2nd ed., Rev. Belo Horizonte: UFMG, 1996).
Os sistemas de tratamento de efluentes são baseados na transformação dos poluentes dissolvidos e em suspensão em gases inertes e ou sólidos sedimentáveis para a posterior separação das fases sólida/líquida.  Effluent treatment systems are based on the transformation of dissolved and suspended pollutants into inert gases or sedimentable solids for further separation of the solid / liquid phases.
O estado da técnica descreve diversos sistemas de tratamento de efluentes que seguem basicamente um conjunto de etapas que inclui o pré-tratamento, tratamento primário, tratamento secundário e tratamento terciário. The prior art describes various wastewater treatment systems that basically follow a set of steps that include pretreatment, primary treatment, secondary treatment and tertiary treatment.
A etapa de pré-tratamento é constituída unicamente por processos físicos, sendo prevista a remoção dos materiais em suspensão e dos sólidos grosseiros.  The pre-treatment stage consists solely of physical processes, and removal of suspended materials and coarse solids is foreseen.
Após, é prevista a etapa de tratamento primário que compreende processos físico-químicos para a equalização e neutralização da carga do efluente, com a separação de partículas líquidas ou sólidas através de processos de floculação e sedimentação.  Afterwards, the primary treatment step is foreseen which includes physicochemical processes for the equalization and neutralization of the effluent charge, with the separation of liquid or solid particles through flocculation and sedimentation processes.
Na etapa seguinte de tratamento secundário, ocorre a remoção da matéria orgânica e de nutrientes, como nitrogénio e fósforo, por meio de reações bioquímicas mediante processos aeróbicos ou anaeróbicos.  In the next stage of secondary treatment, organic matter and nutrients such as nitrogen and phosphorus are removed by biochemical reactions by aerobic or anaerobic processes.
Por fim, a etapa de tratamento terciário ou "polimento" pode ser empregada com a finalidade de serem removidos poluentes específicos (usualmente tóxicos ou compostos não biodegradáveis) em águas residuárias, antes de sua descarga no corpo receptor e/ou para recirculação em sistema fechado, ou ainda para a remoção complementar de poluentes não suficientemente removidos no tratamento secundário.  Finally, the tertiary treatment or "polishing" step may be employed for the purpose of removing specific pollutants (usually toxic or non-biodegradable compounds) in wastewater prior to discharge into the receiving body and / or for closed system recirculation. or for the further removal of pollutants not sufficiently removed in the secondary treatment.
Por definição os métodos de tratamento terciário correspondem ao tratamento avançado de efluentes em que se utilizam técnicas com tamanho poder de remoção dos agentes formadores de esgoto que acabam por tornar possível até o reuso da água. O tratamento terciário prevê métodos de tratamento que visam à desinfecção do esgoto, ou seja, que remove organismos patogênicos dos esgotos e métodos de tratamento que visam à remoção de nutrientes, que tem por objetivo evitar o desequilíbrio quanto à disposição de elementos no corpo receptor, evitando a eutrofização, um fenómeno de crescimento excessivo de plantas aquáticas e organismos como as algas, que têm potencial para a liberação de grande quantidade de toxinas, provocando a morte de peixes, afetando a biodiversidade, liberando gases tóxicos que causam odores desagradáveis e diminuindo a transparência da água. By definition, tertiary treatment methods correspond to advanced effluent treatment using techniques with such high power to remove sewage forming agents that even make water reuse possible. Tertiary treatment foresees treatment methods for sewage disinfection, that is, it removes pathogenic organisms from the sewage and treatment methods for the removal of nutrients, which aims to avoid imbalance in the disposal of elements. in the recipient body, preventing eutrophication, a phenomenon of overgrowth of aquatic plants and organisms such as algae, which have the potential to release large amounts of toxins, causing fish to die, affecting biodiversity, releasing toxic odor-causing gases. unpleasant and decreasing water transparency.
No entanto, a etapa terciária do tratamento de efluentes, responsável pela eliminação de nutrientes químicos como o fósforo, ainda não é comum no Brasil. Com isso, apenas 40% do fósforo do esgoto são eliminados nas duas primeiras etapas, e o restante permanece no esgoto tratado e é liberado no corpo receptor. O fósforo, oriundo das fezes humanas, tem alto poder de contaminação.  However, the tertiary stage of wastewater treatment, responsible for the elimination of chemical nutrients such as phosphorus, is not yet common in Brazil. As a result, only 40% of the sewage phosphorus is eliminated in the first two steps, and the remainder remains in the treated sewage and is released into the recipient body. Phosphorus from human feces has a high power of contamination.
Dessa forma, ainda que variantes destes convencionais sistemas de tratamento de efluentes doméstico e industrial sejam descritos, a característica comum é a necessidade de uma extensa área para instalação da estação de tratamento de efluentes, a produção de odores, gases e lodo residual e o tempo elevado de residência do efluente no sistema antes do lançamento no corpo receptor.  Thus, although variants of these conventional domestic and industrial wastewater treatment systems are described, the common feature is the need for an extensive area for wastewater treatment plant installation, the production of odors, gases and sludge and the time effluent residence in the system prior to release into the receiving body.
Portanto, é objeto da presente invenção um sistema compacto de tratamento de efluentes em tempo real que possibilita o tratamento de efluentes do tipo industrial, doméstico ou misto com tempo de residência do efluente praticamente nulo e sem a produção de odores, gases ou lodo residual, demandando uma área para instalação da estação de tratamento cerca de dez vezes menor que as convencionais, cumprindo integralmente todas as fases do tratamento de efluentes prescritas pela legislação ambiental.  Therefore, the object of the present invention is a compact real-time effluent treatment system which enables the treatment of industrial, domestic or mixed effluents with virtually zero effluent residence time and without the production of odors, gases or residual sludge. demanding an area for installation of the treatment plant about ten times smaller than the conventional ones, fully complying with all the phases of the effluent treatment prescribed by the environmental legislation.
