RESEARCH AND DEVELOPMENT RESOURCESAVING TECHNOLOGY PRODUCTION BIOMINERAL FERTILIZER FROM WASTE TREATMENT FACILITIES WITH THE ADDITION OF FALLEN LEAVES

The urgency of the solution creating new types biomineral fertilizer, waste disposal and intensification of the anaerobic digestion process. Found that the preliminary dispersion the input of raw materials increases the speed of process anaerobic digestion in 1.6 times. The dependences of the volume biogas from the duration the anaerobic digestion process. It is shown that maximum amount biogas 0,57 m3/kg can be obtained using as starting materials compacted active sludge, fallen leaves and sediment after phosphate removal sludge production of calcium nitrate. Chemical analysis of the fertilizer is made. It is shown that the fertilizer based on waste treatment facilities with the addition of fallen leaves has the following composition, %: C – 52,0; Ntot. – 3,80; P2O5 – 5,77; K2O – 25,30; CaO – 9,8. The technological scheme of resourcesaving technology of production biomineral fertilizers from the waste, which the use of deposition phosphates, compaction of activated sludge production of calcium nitrate and dispersion of the feedstock to increase the speed of the anaerobic digestion process.
