[0023] Based on the above-mentioned structural setting, the storage and regulation system suitable for the combined sewer intercepting type sewage pipe network is composed of a retention well 2, a treatment tank 3 and a storage and regulation tank 6, wherein the retention well 2 is connected to the treatment tank 3 and the storage and regulation tank 6 respectively by a connecting pipe 12 and a water pipe 11, and a sewage pipe 5 is installed at the rear end of the retention well 2 on the other side of the water pipe 11, and the interception valve 4 installed on the sewage pipe 5, the water pipe 11 and the connection pipe 12 is a normally closed valve. Specifically, during the working process, the water level detector 10 is used to monitor the water level inside the retention well 2, the treatment tank 3, the storage and regulation tank 6 and the water storage tank 8. The detection data is transmitted to the remote control room for analysis and processing, and the sewage is guided to the interior of the interception well 2 by the water inlet pipe 1. After entering, the interception valve 4 on the connecting pipe 12 is opened, and the sewage inside the interception well 2 is discharged to the interior of the treatment pool 3 through the connecting pipe 12 for pre-storage, and then discharged to the sewage treatment plant through the pipeline to realize sewage treatment, thereby reducing the pollution to the environment caused by direct discharge of sewage into the river. When the capacity of the treatment pool 3 has reached the maximum value, the interception valve 4 on the connecting pipe 12 is closed, and the interception valve 4 on the water guide pipe 11 is opened. 2 is discharged to the inside of the regulating reservoir 6 through the water pipe 11 for storage. When the regulating reservoir 6 is stored to a certain water level, it is sequentially drained to the inside of the water storage tank 8 through the diversion pipe 9 for storage. When the regulating reservoir 6 and the water storage tank 8 reach the maximum storage value, the interception valve 4 on the water pipe 11 is closed, and the interception valve 4 on the sewage pipe 5 is opened to discharge the sewage inside the interception well 2 to avoid overflow of the interception well 2.
