Abstract
This research considers the effective use of the sewage sludge whose quality has changed by electrolytic treatment as a sewage deodorizer. The demonstration experiment was implemented at a sewage sludge compost plant for the purpose of the practical use of electrolytically treated sewage sludge. In the experiment, some sample was adjusted to low-concentrated odor, and afterwards to high-concentrated odor. This method led to the high deodorizing effect of the sample even when it was exposed to the original odor. This result shows that, although the deodorizing bacteria in the sewage sludge met limitation since the optimum environment for the bacteria was destroyed with the highly-concentrated original odor, this deodorizing method is practically useful in that when sample is regularly replaced by newly-adjusted one, more continuous deodorization should be possible and the ways of sewage sludge use should be varied without cost problems.
