Impact of effective microorganisms bacteria on low-input sewage sludge treatment

Six-month experiments have been carried out using pilot installations of low-budget methods of sewage sludge treatment. Sewage sludge was processed using vermiculture or plants such as willow or reed. The study was also conducted in a solar dryer. In some parts of the research, effective microorganisms were used. The results of the sediment research, including: contents of organic and mineral matter, hydration reaction, contents of nitrogen and phosphorus, as well as the indicators of the sanitary condition, were presented. The results confirmed a perceptible influence of the effective microorganisms on the structure of the dry mass of dairy sewage dewatered on reed and willow plots or transformed into vermicompost. A slight, however, apparent difference in a faster and more effective mineralization of organic substances contained in the sludge after half a year of processing, as well as significant reduction of the number of potential pathogenic bacteria was observed.
