High-temperature anaerobic treatment method and high-temperature anaerobic wastewater treatment device

摘要

PURPOSE:To prevent sludge activity from deteriorating during low load operation and make sure the stable treatment of waste water by increasing/decreasing the number of aerophobic treatment tanks which introduce and heat an untreated water in accordance with variations of the organic substance concentration and/or flow of the introduced untreated water, and ensuring that the aerophobic treatment tank in which the untreated water is not introduced is not heated. CONSTITUTION:The number of aerophobic treatment tanks 1 to 3 which introduce and heat an untreated water in accordance with variations in the organic substance concentration and/or flow of an introduced untreated water, is increased and decreased. Then the aerophobic treatment tank in which the untreated water is not introduced. That is, a load close to a maximum load is given to sludge to which a load is given to maintain its activity by appropriate control even under low load conditions, and the activity can be maintained on the remaining sludge by stopping heating. Thus even the untreated water showing a significant load variation can be treated stably and efficiently.
