  An effective non-local quantum field theory is constructed, which describes
interaction of pomerons in the high-coloured QCD. The theory includes both
splitting and merging triple pomeron vertexes and diagrams with pomeronic
loops. The Schwinger-Dyson equations for the 'physical' pomeron are written.
Conformal invariance allows to reduce the theory to the old-fashioned Gribov
pomeron theory with an infinite number of pomerons, one of which is
supercritical.
