COMBINED TREATMENT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a combined treatment equipment capable of solving the disposal problem of a single treatment and purification tank and treating various types of household wastewater at a low cost by effectively utilizing such an existing single treatment and purification tank (equipment). SOLUTION: This combined purification equipment realizes combined treatment of both human waste and miscellaneous household wastewater by utilizing an existing single private treatment purification tank (equipment) 1 and connecting the treatment and purification tank 1 to a second treatment and purification equipment 15. The second treatment and purification equipment 15 has a biological contact aeration vessel 16 and a sedimentation vessel 17 and is connected to the purification tank 1 with a transfer pipeline 26. Wastewater immediately before flowing into a disinfection chamber 24 of the treatment purification tank 1 is allowed to flow into the biological contact aeration vessel 16 of the second equipment 15. Treated wastewater in the sedimentation vessel 17 is returned to the disinfection chamber 24 of the treatment and purification tank 1 through a return pipeline 26 connected to the disinfection chamber 24; and finally, thus treated and purified wastewater is discharged to the outside of the system through an outflow port 12 of the treatment and purification tank 1.
