Modified Anaerobic Baffled Reactor and Method For Volatile Fatty Acids Production

摘要

The present invention relates to an anaerobic acid fermentation apparatus for treating and recycling organic waste sludge (waste solid matter) generated in a wastewater treatment process, and a method for producing anaerobic organic acid using the same, and more particularly, . In the present invention, the agitation tank (2) in which the anaerobic acid fermentation of the introduced waste sludge mixed liquor proceeds by agitation in the anaerobic state; And a multistage bulkhead-type baffle tank (3) provided at the rear of the stirring tank (2) and in which the precipitation and solid-liquid separation of the mixed liquid through the stirring tank (2) proceed in the anaerobic state; The multi-stage partition wall type baffle tank (3) is provided with a partition space set consisting of a downward flow space in the front side and a upward flow space in the rear side with a lower end opening partition wall opened at the lower end thereof, The incoming mixed liquor passes through the downflow space and the upflow space alternately in succession to precipitate the solids and perform solid-liquid separation; In each of the partition space sets, the settled waste sludge is conveyed to the agitating tank 2 through the return pipe, the waste sludge is discharged to the outside through the sludge outlet in the last partition space set, And the anaerobic organic acid production method using the anaerobic organic acid fermentation apparatus and the anaerobic organic acid production method are provided.
