PROCESS AND TECHNOLOGY FOR TREATING AND REUTILIZING COMMUNAL SEWAGE, LIQUID MANURE AND THEIR SLUDGES INPURIFYING PLANTS WITH RUBBLE FILTER AND OTHER FILTERS, WORKING WITH BAD EFFICIENCY

摘要

Improvement of existing inefficient domestic sewage, liq. and solid manure handling plants is achieved by providing the farms storage and separating basins with exchangeable containers. These containm mineral filtering material or an opt. mineral mixt. There is a novel method also for composting solid phases. Prior to ripening the manure it is mechanically mixed with minerals. Such compsn. has no smell, is not infectious and is richer in nitrogen. It does not have to be agitated, it contains natural organic and mineral matter and obviates the need for fertilisers and their unwanted effect
