<p>PROBLEM TO BE SOLVED: To provide a waste water treatment apparatus equipped with an unaerobic bioreactor container automatically detecting abnormality, starting a washing process automatically to eliminate the abnormality caused by the clogging of a distribution pipe and enabling stable long-term unmanned operation. SOLUTION: This waste water treatment apparatus equipped with an unaerobic bioreactor container distributing raw water such a waste water to a distribution pipe 4 to bring the same into contact with a granular solid bed of unaerobic bacteria to treat raw water is constituted of the pressure gauge 7 and flowmeter 8 arranged on the inflow side of the inflow raw water distribution piping of the unaerobic bioreactor container 3, a controller 9 inputting the measuring signals of the pressure gauge 7 and the flowmeter 8 and judging automatic washing timing to perform control output, an inflow valve 10 receiving the output of the controller 9 to open and close and a washing waste water valve 11. By this constitution, the distribution pipe 4 is automatically washed by automatically detecting the abnormal operation state of the unaerobic bioreactor container to make it possible to remove the clogging of the distribution pipe 4. Therefore, stable long-term unmanned operation can be performed without allowing treated water bad in quality to flow out.</p> |
