A utilização do processo de compostagem para tratamento de lodo de estação de tratamento de efluentes

Abstract

The generation of waste in an uncontrollable way, without opposition to the evictions in water resources and its negative consequences to the public health and the environment, made the man change his way of acting and look for new alternatives to treat his. Through a research based on practices and information of the company Farol Indústria e Comércio S.A located in the western region of Santa Catarina, the objective was to demonstrate the sócio-environmental and economic viability of the application of the composting process for sludge treatment from effluent treatment plants. Using the monitoring of laboratory reports of the company, a comparative study was carried out with the legislation of the Ministry of Agriculture in order to evaluate the quality standards of ready compound. The analyzed parameters are physical chemical parameters, heavy metals and microbiological. Environmental safety has been found to stabilize and clean up sludge resulting in a safe product with numerous agronomic advantages and comply with standards regulated by legislation and relevant bibliography. The stabilized product makes it environmentally safer, brings social benefits and increases its commercial value, in this way, composting presents itself as a viable sócio-environmental technique, but has become questionable financially.
