ものである。INDUSTRIAL APPLICABILITY As described above, the present invention provides BO for domestic wastewater.
Since it is made to flow into the optimum processing tank depending on the D value,
Since the treated water with a high D value is in an untreated state and is kept flowing into the treatment tank on the downstream side to keep the purification condition of the treatment tank constant, the deterioration of the purification rate due to the fluctuation of the flow rate of the wastewater is remarkable. Since the purification is performed in a stable manner with a reduced purification rate and a high purification rate, the purification efficiency can be significantly improved,
It is possible to realize an excellent sewage treatment method that can reduce water pollution of rivers and seas by domestic wastewater and purify and improve the environment.

A sewage treatment method in which toilet wastewater, bath wastewater, laundry wastewater, and other miscellaneous wastewater are combined to purify the wastewater, and the wastewater is transferred to an aerobic tank through an anaerobic tank. Using a combined treatment septic tank in which the anaerobic tank is divided into two or more tanks, each wastewater flowing into the combined septic tank is combined into one to form a domestic wastewater system, and the BOD value of the wastewater of this domestic wastewater system is detected by a BOD substitute sensor in advance. Then, the output opens and closes the solenoid valve that communicates with each septic tank via the solenoid valve control unit, causing wastewater with a high BOD value to flow into the anaerobic tank on the upstream side, and wastewater with a low BOD value to the anaerobic tank on the downstream side. A sewage treatment method characterized in that the sewage treatment is carried out by dispersing and flowing into a tank or an aerobic tank.
