METHOD OF WASTEWATER DISPOSAL

摘要

A method in which solid-liquid separation for active sludge and treated liquid can be carried out stably and efficiently by implementing necessary and sufficient measures through appropriate assessment of any risk of clogging before actual membrane clogging.There is provided a method of wastewater disposal according to a membrane separation active sludge technique, comprising determining an upper limit value of BOD-sludge load with the use of BOD value and index for the total organic matter content of organic wastewater and carrying out regulation so that the BOD-sludge load in active sludge vessel does not exceed the above upper limit value.
