NOVELTY - The system (10A) has organic substance concentration measurement unit (15) that measures organic substance concentration in industrial-park waste water (11) flows into primary treatment unit (13). An activation agent administration unit (17) administers activation agent (16) activating important microorganisms in activated sludge to secondary-treatment unit. The composition in influent (11B) is judged, by result of measurement unit. The agent is administered corresponding to judged composition, and activity of microorganisms is improved by administration of agent.    USE - System for processing waste-industrial-water from factory.    ADVANTAGE - Since the organic substance concentration in the flowing-in waste industrial waters is measured by the organic substance concentration measurement unit, and the activation agent is administered by the activation agent administration unit, the countermeasure which raises the processing speed of the microorganisms in the activated sludge process equipment in advance is received by the secondary-treatment unit easily.    DETAILED DESCRIPTION - The system has a primary treatment unit which carries out primary treatment of industrial-park waste water, and secondary-treatment unit which carries out secondary treatment of influent processed by primary treatment unit with activated sludge. The primary treatment unit has buffer tank (12) which accepts and stores industrial-park waste water temporarily, and measures organic substance concentration in industrial-park waste water which flows into buffer tank by organic substance concentration measurement unit. The microorganism abundance-ratio measurement unit performs abundance-ratio measurement of the important microorganisms of the secondary-treatment unit. The microorganisms are appropriate corresponding to composition in influent is judged. The activity is improved by administration of the activation agent corresponding to the judged composition for microorganisms. The active condition of microorganisms of the secondary-treatment unit is grasped by respiration rate measurement unit. A portion of influent from before flowing into the buffer tank is extracted, and a bypass line which bypasses primary treatment unit is provided. The influent with high organic substance concentration from the primary treatment unit is temporarily stored in high-concentration-waste-water storage tank. The organic substance high concentration influent is mixed instead of the activation agent with the influent which flows into the secondary-treatment unit. A film process of effluent is carried out from secondary-treatment unit by film processing apparatus. The effluent is regenerated after process with the film processing apparatus, by regeneration processing apparatus. An INDEPENDENT CLAIM is included for a waste-industrial-water processing method.
