PROCESS FOR THE TREATMENT OF SLUDGES OF MUNICIPAL WASTE WATER

摘要

The invention relates to the technology for the treatment of sludge of municipal sewage plants and can be used for the treatment of similar sludge.The task of the invention is the increasing of the decomposition degree of organic substance of sludge, excluding its supply after the treatment to the dehydration.The set task is achieved by the way that desilting is carried out by the clarification in suspended layer of sludge with hydraulic loading of sludge water of 0.1-0.5 m/(mhour) and the ratio of height of zones of suspended and protective layers is not less than 3:1, and recirculation in aerobic mineralizer a whole arrested in desilting sludge is given.
