PROCESS FOR THE TREATMENT OF SLUDGE OF SEWAGE-DISPOSAL PLANTS AND POND OOZE BY THE METHOD OF BIOLOGICAL FERMENTATION

摘要

The process for the treatment of sludge of the sewage-disposal plants and pond ooze by the method of biological fermentation is characterized with the fact that before the fermentation compost mixture of components is prepared by the computational method due to moisture index, nitrogen and carbon, on the ground the sludge of sewage-disposal plants or pond ooze is mixed with bird dung, cattle or swine manure with the addition of peat or shredded straw, or reed, or leaves of microbiological preparation "Vermystym-D" to 1 % of kainite and 2 % of phosphoric powder from the volume of compost mass. Before the loading into the biofermenter the moisture of compost mass should be of 50-60 %. Besides the ratio of nitrogen and carbon in mixture should be 1:20-1:30. The process for the biological fermentation is carried out due to the developed production procedures of 7-11 days.
