BIOCHEMICAL REACTOR OF LIQUID CURRENT TYPE, GROUNDWATER AND WASTEWATER PURIFYING SYSTEM EQUIPPED THEREWITH, AND LIQUID TRANSPORT-STIRRING APPARATUS THAT EMPLOYS THE TRANSPORT MEANS USED IN SAID REACTOR AND SYSTEM

摘要

A biochemical reactor comprises a vessel to hold an immobilizing carrier and a raw liquid and means for circulating the immobilizing carrier and raw liquid throughout the vessel, the circulating means including a rotary drive, a tubular centrifugal force generator which is rotated by the rotary drive and has a suction passage extending outwardly from the axis of rotation and terminating with an outlet, and a tubular fluid guide which has an inlet at one end thereof and an internal passage extending from the inlet and in fluid communication with the suction passage of the centrifugal force generator, the inlet of the fluid guide and the outlet of the centrifugal force generator being distanced within the vessel. The fluid transport-stirring apparatus is capable of transporting and mixing any desired fluid.
