Abstract

Sewage sludge is composted by a process of decompsn. controlled by the volume of air fed into the mass. The sludge from which the bulk of the water has been extracted, is fed in, mixed with a source of carbon such as peat, sawdust or recirculated compost, to a reactor, into which air enriched with pure oxygen is blown from below in a contrary direction to the movement of the sludge, setting up zones of differing temp. and oxygen content the hottest zone being in the upper third of the mass and that with most oxygen in the lower third.

Description

Изобретение относитс  к сельскому хоз йству, в частности к способам получени  органических удобрений .The invention relates to agriculture, in particular to methods for producing organic fertilizers.

Известен способ биологической очистки воды, при котором твердые частицы, содержащиес  в суспензии, выпадают в осадок и как шламм происход щего цикла очистки извлекаютс  1J .A known method for the biological purification of water in which solid particles contained in a suspension precipitate and how the sludge of the purification cycle that takes place is extracted 1J.

Однако данный способ эффективен только дл  сточных вод.However, this method is effective only for wastewater.

Известен способ компостировани  отстойного шлама, включающий смешивание его с носителем органического углерода, в аэрационном реакторе с принудительной подачей обогащенного кислородом воздуха в противоток компостируемому отстойному шламу С2 .There is a known method for composting sludge sludge, which includes mixing it with a carrier of organic carbon in an aeration reactor with forced supply of oxygen-enriched air to the countercurrent to compostable sludge C2.

Однако Известный способ недостаточно эффективен.However, the known method is not effective enough.

Цель изобретени  - регулирование процесса ферментации и осуществление непрерывного процесса.The purpose of the invention is the regulation of the fermentation process and the implementation of a continuous process.

Это достигаетс  тем, что в процессе смешивани  шлама с носителем органического углерода добавл ют воду и бентонитовую, муку, а воздух.This is achieved in the process of mixing the sludge with a carrier of organic carbon, water and bentonite flour, and air are added.
