Multi-use shaft, small-scale water purification plant and water treatment method

摘要

The final breakdown of fresh compost is accelerated by an earthworm colony moving through a steady incoming compost supply on a moving conveyer in a continual process. As in claim DE 3812518-A1, freshly composted material (9) is finally composted by earthworms (19) which feed and migrate progressively to further incoming supplies of fresh compost. Worms migrate horizontally towards fresh compost which is preceded by further fresh incoming compost, maintained as a continual supply in an elongated pile (3) of more than two meters length by a conveyer-fed supply moving towards the worms. The fresh compost and worm-assisted compost heap are positioned on a moving surface e.g. circular, oval or linear conveyer, the speed of which is determined by the current position of the feeding worm colony. The position of the feeding worms is determined by sensors (23,24). The composting material passes over a hot zone (7), under a mechanical hoe (12) and heap inverter (17). The finally composted material is discharged (5) prior to the fresh compost inlet.
