Abstract
PURPOSE: To prevent reduction of permeation efficiency due to pollution of the membrane surface by holding an interior of a system under oxidative atmosphere always or intermittently in subjecting an org. or an inorg. reductive substance to the membrane separation.
CONSTITUTION: A fluid containing the org. or the inorg. reductive substance, for example, the fluid 1 containing excretion is supplied to a biochemical tank A to subject said fluid to biochemical oxidative decomposition and the resulting reaction slurry 2 is subjected to solid-liquid separation by a solid-liquid separation apparatus B and the separated liquid is forced into a permeation memberane apparatus E. In this time, an oxidative substance such as ferric chloride, ferric sulfate, stannic chloride, chlorine gas, a hypochlorite, ozone, oxygen or a peroxide is added to the separated liquid 6 either alone or in combination thereof to hold the interior of permeation membrane treatment system under the oxidative atmosphere always or intermittently.
