Abstract:

The general attitude of the wastewater treatment process in our country is focus on the effluent quality and unfortunately waste sludge quality is rarely considered. Since multiple natural hazards and routes the contact with sludge requires a comprehensive approach to protect public health and the environment. The aim of this study is an assessment of sludge management and finding out the potential use of sludge for land application. The study was conducted in January to December 2014. samples were gathered in four seasons, winter, spring, summer and autumn from wastewater treatment plant in industrial park of Shokohieh of Qom province according to the instructions in standard method. Sampling was moments and composite. Numbers of Samples were 24 that 2 samples were captured in every month. Samples measured base on standard method for water wastewater examination references and then data was analyzed by SPSS and t-test. The results show that the Physical Parameters qualities and nutrients qualities in sludge are good. The Phosphate quality is not suitable. Based on t-test, the results show that levels of fecal coliform and total coliform in cold and warm seasons are different (P <0.001). This study showed that sludge ranked in Class B (EPA standard). The results of this study indicate that relationship between levels of parasite eggs and fecal coliforms is the best (pearson coefficient=0.995). The correlation coefficient levels of parasite eggs and total coliforms are 0.969. The mean values of elements are upper than the EPA standards, except lead, arsenic, mercury, cadmium and zinc. This study shows that sludge ranked in Class B therefore is not suitable for various uses of sludge as: grass, playgrounds, for other uses, such as farmland and forest. Sludge has high levels of toxic metals, which are inapplicable due to the accumulative property.
