PURPOSE: To efficiently separate an organic material such as a sewage sludge by mixing a specific quantity of a chelating agent and an enzyme with a liquid organic material and a biomass and executing a middle or high temp. aerobic oxygen treatment.
CONSTITUTION: The liquid organic material and biomass, the municipal sewage sludge as a very suitable example, is mixed with 0.001-0.1wt.% chelate compound, suitably nitro triacetate and further 0.001-1.5wt.% enzyme or enzyme compound. Next, after the organic component is decomposed at a middle or high temp., the sludge is introduced into an aerobic reactor. Strong aeration is executed in the reactor and in such a case the aeration is stopped before the decomposition is completed after 5-20hr and a non-aerating post reaction is executed for 5-15hr. Next, after degassing, solid-liquid separation is performed.
