THE PROBLEM OF DISPOSAL SLUDGE TREATMENT PLANTS

Abstract

Consider the features of the formation and disposal of sludge. It is noted that the methods of sludge treatment in digesters or throw them in the sludge beds are not perfect. The presence of high concentrations of nitrogen and phosphorus in sewage sludge would allow its use as a fertilizer, but it is necessary to consider that may contain heavy metals that contaminate the environment. It noted a huge amount of sludge produced per year in Russia. A preferred method of disposal of sewage sludge - sludge storage in the fields. Sludge fields pose a threat to the environment due to the high content of dangerous viruses, bacteria, harmful gases, hazardous chemicals In this work it was studied the composition of the sludge. It has been determined that the precipitation contained a significant amount of organic material that is fat, protein, carbohydrate, etc. The aqueous phase of the sludge is characterized by a neutral environment.
