ANAEROBIC WASTE WATER TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an anaerobic waste water treatment system which rapidly and exactly controlling the pH of waste water and additionally enhances the efficiency of cleaning of the waste water by efficiently carrying out biological treatment by anaerobic bacteria of the waste water. SOLUTION: This anaerobic waste water treatment system has a pH control vessel 1, an anaerobic bioreactor 2 which is connected across a reactor pipe 12 to the pH control vessel 1 and a treated water vessel 3 which is connected across a treatment pipe 13 to the anaerobic bioreactor 2 and is connected across a return pipe 15 to the reactor pipe 12. The reactor pipe 12 is fitted with a first pH detection meter 21 and the treatment pipe 13 is fitted with a second pH detection meter 22. A drug feed controller 32 controls a drug feed pump 31 in a feedback manner in accordance with the detection signals from the first pH detection meter 21 and the second pH detection meter 22.
