<p>Nos últimos anos, a preocupação com as questões ambientais vem sendo bastante discutidas, onde merece destaque, o descarte indevido do esgoto doméstico no meio ambiente, portanto o presente estudo objetivou realizar a caracterização físico-química e microbiológica do esgoto descartado no solo, no Centro de Ciências e Tecnologia da Universidade Estadual da Paraíba, campus de Campina Grande – PB. Para tanto foram desenvolvidas análises físico-químicas, tais como pH, Fósforo Total, DBO, DQO, Nitratos, Nitritos, Nitrogênio Amoniacal, Orto-Fosfatos e Alcalinidade, bem como análise microbiológica (coliformes). Observou-se que o efluente na unidade em questão não recebe tratamento para seu descarte, sendo identificadas características físico-químicas e microbiológicas de esgoto <em>in natura</em>. Faz-se necessário desta forma, investimentos em análises periódicas para assim realizar um tratamento adequado ao efluente visando-se reduzir os riscos ambientais e de saúde pública. Após os resultados das análises, foi proposto, além do tratamento preliminar, um tratamento biológico para o efluente, do tipo, lagoa facultativa primária seguida de duas lagoas de maturação, onde a eficiência do tratamento nos parâmetros analisados se enquadra aos padrões estabelecidos pelo CONAMA 430/2011, na qual o efluente pós - tratado poderia ser reutilizado para fins menos nobres, destinando a água potável para atividades que requerem uma qualidade melhor.</p><p><strong><em>Physicochemical and microbiological characterization of wasterwater of the UEPB with proposed of treatment for reuse purposes</em></strong></p><p><strong>Abstract</strong><strong>: </strong>In recent years, concern about environmental issues has been widely discussed, which deserves mention the improper disposal of domestic sewage into the environment, so this study aimed to perform the physicochemical and microbiological sewage discarded the soil, in the Science and Technology Center of the State University of Paraiba, campus of Campina Grande - PB. Therefore, we developed physical-chemical analysis such as pH, Total Phosphorus, BOD, COD, Nitrate, Nitrite, Ammonia Nitrogen, Orto-Phosphates and alkalinity, as well as microbiological analysis (coliforms). It was noted that the effluent in the unit in question does not receive treatment for their disposal, identified physical, chemical and microbiological characteristics of raw sewage. It is necessary therefore, investment in periodic reviews thus to carry out an appropriate treatment to effluent aiming to reduce environmental risks and public health. After the analysis results, it was proposed, in addition to preliminary treatment, a biological treatment for the effluent, type, primary facultative pond followed by two ponds maturation, in which the treatment efficiency in the analyzed parameters falls within the standards set by CONAMA 430/2011 in which the effluent post-treaty could be reused for less noble purposes, intended to clean water for activities that require a better quality<strong>.</strong></p>

Abstract Pharmaceutical wastewater biological treatment plants are stressed with multi-component wastewater and unexpected variations in wastewater flow, composition and toxicity. To avoid operational problems and reduced wastewater treatment efficiency, accurate monitoring of influent toxicity on activated sludge microorganisms is essential. This paper outlines how to predict highly toxic streams, which should be avoided, using measurements of biochemical oxygen demand (BOD), if they are made in a wide range of initial concentration. The results indicated that wastewater containing multivalent Al3+ cations showed a strong toxic effect on activated sludge biocenosis irrespectively of dilutions, while toxicity of phenol and formaldehyde containing wastewater decreased considerably with increasing dilution. Activated sludge microorganisms were not sensitive to wastewater containing halogenated sodium salts (NaCl, NaF) and showed high treatment capacity of saline wastewater. Our findings confirm that combined indicators of contamination, such as chemical oxygen demand (COD), alone do not allow evaluating potential toxic influence of wastewater. Obtained results allow identifying key inhibitory substances in pharmaceutical wastewater and evaluating potential impact of new wastewater streams or increased loading on biological treatment system. Proposed method is sensitive and cost effective and has potential for practical implementation in multiproduct pharmaceutical wastewater biological treatment plants.

Waste Accumulation

Microplastics is one category of plastics with relatively small diameter and is considered as the common ingredient of waste accumulation zone in oceans. However, since countless plastic products are emitted into oceans annually as waste all around the world, pollution caused by them is severe and the resulting problems have attracted attention globally, while current policies and cooperation around the globe for tackling microplastics pollution still need to be improved. To deal with microplatics-related problems in the ocean, our review first discussed the toxicity of microplastics based on previous research related to marine microplastics, which was caused by the plastics themselves and their leaching substances with impacts on marine creatures and human body along the food chain. After summarizing some measures that have been already performed, we suggested that the authority should take more actions to mitigate those problems resulted from microplastics, pay more attention on researching, and encourage citizens to offer their proposals. By finally analyzing the advantages and disadvantages of different handling methods, as well as physical, chemical, and biological treatment technologies on oceanic microplastic issues, our work provided experience on disposing microplastics waste under various actual situations with an example for more holistic waste treatment.

Harmful Substances

Most landfills dont meet the requirements for the terms of waste disposal and are just dumps without any engineering infrastructure protecting biosphere objects from polluting. Chemical and microbiological processes occurring in the municipal solidwaste mass lead to the formation of harmful substances polluting water objects. The designs of landfills MSW should have a two-stage scheme of wastewater treatment. The first stage of treatment is done in ponds-regulators of high capacity by homogenisation, dilution and long-lasting settling of wastewater. The second stage of treatment is performed on plants of physical-chemical and biological treatment. Negative influence of the rest harmful substancesdecreases if there is a big enough natural biochemical barrier between the water wall and the nearest water-bearing level, i.e. if the basement of the landfill has rocks that can effectively prevent pollutants taking out to ground water levels.
