PROBLEM TO BE SOLVED: To provide an anaerobic treatment system and anaerobic treatment method capable of sufficiently suppressing the outflow of granule sludge.SOLUTION: An anaerobic treatment system 1 includes: an anaerobic treatment vessel 12 in which organic waste water is made to be subjected to anaerobic treatment by storing granule sludge formed through granulation of anaerobic sludge and making the introduced organic waste water W flow upward and making it contact with the granule sludge, a sedimentation vessel 7 into which treated water W1 discharged from the anaerobic treatment vessel 12 is introduced and the granule sludge contained in the treated water W1 is separated and returned to the anaerobic treatment vessel 12, and a treated water conveyance line L5 which conveys the treated water W1 by connecting the anaerobic treatment vessel 12 and the sedimentation vessel 7. The treated water conveyance line L5 has a treated water dropping part 51 which drops and moves the treated water W1 that is sent to the sedimentation vessel 7 and a collision member 57 which makes the treated water W1 dropping and moving at the treated water dropping part 51 collide. |
