Purification system for groundwater or wastewater; biochemical reactor and liquid-transport stirring apparatus

摘要

The biochemical reactor of liquid current type comprises a vessel (4) to hold an immobilizing carrier (95) and a raw liquid (96) and a transport means for transporting and circulating said immobilizing carrier (95) and said raw liquid (96) over a certain distance from one place to another in said vessel (4), said transport means including a rotary drive (9), a tubular centrifugal force generator (2) which is turned by said rotary drive (9) and has a suction passage (11) extending outward from the axis of rotation and terminating with an outlet (10), and a tubular fluid guide (3) which has an inlet (3h) at one end thereof and an internal passage extending from said inlet (3h) and communicating with said suction passage (11) of said centrifugal force generator (2), said inlet (3h) of said fluid guide (3) and said outlet (10) of said centrifugal force generator (2) being positioned apart in said vessel (4). The fluid transport-stirring apparatus is capable of transporting and stirring any desired fluid by the aid of said transport means.
