ANÁLISE DA INFLUÊNCIA DA SAZONALIDADE NA EFICIÊNCIA DA ESTAÇÃO DE TRATAMENTO DE ESGOTO DO MUNICÍPIO DE CALDAS NOVAS - GO

Abstract

Due to the disordered development of cities in the formation of large urban centers, together with the lack of sanitary planning, brings great concerns related to the environment and the welfare of the population. The city of Caldas Novas has one of the largest hydrothermal springs in the world and due to its rapid and disorderly urbanization as a result of investment in tourism has developed several environmental problems in its infrastructure, as it has not kept up with population growth, significantly increasing production. sewage causing problems of sewage leakage due to deficient treatment capacity. Thus, the objective was to evaluate the variation of the efficiency of the municipal sewage treatment plant and the interference of seasonality through the analysis of the parameters pH, Temperature, BOD, COD and Suspended Solids and to verify if the parameters are within acceptable standards. by legislation. According to the analysis of the period averages for each parameter, it was observed that there is great variability between them, indicating influence of seasonality. Regarding the efficiency of the treatment, it was satisfactory and with values ​​within the limits required by state legislation, Decree no. 1,745 / 1979 and federal legislation CONAMA Resolution 430/2011. By analyzing the COD / BOD ratio, it was noted that there was no efficiency in the removal of biodegradable matter. The OSH presented good efficiency and within what is estimated in the literature.
