NOVELTY - 0.01-0.05 wt% Enzyme is added to a filtrate obtained by removing solids from organic waste liquid by primary solid-liquid separation process. The filtrate is fermented at 25-50 C and fine paper fiber is removed by a secondary separation process. The filtrate is fermented under aerobic condition at high temperature. The fiber is dehydrated to a predetermined moisture content in atmospheric air to form a compost.    DETAILED DESCRIPTION - 0.01-0.05 wt% Enzyme such as lipase, cellulose or protease is added to the filtrate obtained by removing solid substances such as metal pieces, rubber, plastics, cloth and ballast from waste liquid by the primary solid-liquid separation process. The filtrate obtained is subjected to aerobic fermentation under aeration conditions of 25- 50 Nm3/BOD kg/day at 50-80 C. The filtrate is subjected to secondary separation process to remove the remanent paper fiber. The obtained filtrate is fermented and under aerobic conditions and at high temperature. The obtained fiber is dehydrated to a predetermined moisture content in atmospheric air to form a compost.    An INDEPENDENT CLAIM is also included for the processing apparatus. The organic waste liquid, is supplied through a hose (2) and a pipe line (4) from a dipping vehicle (1). A solid- liquid separator (5) isolates solid substance such as rubber plastics, cloth, metal piece ballast and filtrate obtained is supplied to an equalizing tank (6) where it is stored. Enzyme is added to the equalizing tank using an enzyme formulation addition unit (7) and is stirred by a stirrer (8). The filtrate is fermented at low temperature and is supplied to solid-liquid separator (16) where paper fine fiber is removed. The filtrate obtained is stored in a tank and aerobic fermentation is performed at high temperature by supplying air from an aerator. The fermented liquid is stored in liquid fertilizer pool and is stirred by a stirrer. The obtained fiber is dehydrated and stored as compost raw material in a storage unit. Then filtrate is supplied to solid-liquid separator (15) to separate inflammable solid substances followed by dehydrating it. The inflammable substance is conveyed to an incinerator (17) and is incinerated.    USE -   For processing waste liquid containing faeces, urine, rubber, plastics, cloth, metal pieces and ballast.    ADVANTAGE -   Solid substances having low specific gravity and inflammable substances are easily removed. Waste liquid is fermented uniformly and a good compost is manufactured. Inorganic impurities are removed therefore, deposition of impurities in liquid fertilizer pool and spraying apparatus is prevented.
