| Summary: | The object of study is regularities of the anaerobic digestion process for drains treatment. This helps to improving environment.
The method of anaerobic digestion is effective for wastewater treatment from biological contaminants. The important advantage of the method is lack of negative effect to environment. Biogas is released during the process. Strict temperature limits and lack of oxygen are limited the process.
It was found that the optimum temperature of the process is 54-55 ºC. At temperatures below 37 ºC the amount of Enterobacteriaceae increases even in comparison with the initial values, and the content of helminths increases. Increasing the temperature to 45 ºC leads to destruction of helminths, but sufficiently large number of enterobacteria are still present in the sludge. At a temperature of 55 ºC the content of Enterobacteriaceae decreases. Continuous and fed batch ways of fermentation process are found to be the most effective. |
