METHOD FOR REDUCING SLUDGE USING A POPULATION OF OLIGOCHAETA HELD IN A REACTOR, A DEVICE THEREFOR, AND THE USE OF NESTLING OLIGOCHAETA FOR REDUCING SLUDGE IN A REACTOR

摘要

The invention relates to a method for reducing sludge, comprising steps for: i) holding a population of oligochaeta in a reactor, in a reactor medium flowing through the reactor, under conditions which are optimal for oligochaeta in respect of metabolism and reproduction; and ii) adding sludge to the reactor medium, to a device for performing the method, comprising a reactor, means for supplying and discharging reactor medium and sludge, and a carrier suitable for carrying nestling oligochaeta, and to the use of nestling oligochaeta, preferably Aulophorus furcatus, in the reduction of sludge in a reactor.
