[0002] The existing patent "A clear water tank overflow regulating weir suitable for multiple working conditions" solves the problem that when a deep treatment unit is reserved in the water supply plant process, the design water level and overflow weir of the superimposed clear water tank are designed according to the long-term working conditions, resulting in the idle upper volume of the clear water tank and low utilization efficiency of the clear water tank in the recent working conditions; the existing patent "An integrated device for combining a filter tank and a clear water tank" has invented a device for combining a filter tank and a water tank; the existing patent "A clear water tank water level automatic control device" has invented a method for automatically controlling the water level of the clear water tank. However, the technology aimed at solving the problem of sharing the capacity of the newly built clear water tank and the existing clear water tank has not yet been invented.

[0003] The existing water supply plants in some areas face two problems: 1. The existing water supply plants have simple process technology and are too old to meet the requirements of drinking water hygiene standards; 2. As the service area expands or the service population increases, the existing water volume is difficult to meet the standards. In order to solve the above problems, such water plants need to take expansion measures, and the water output standards need to be improved. However, such water plants are generally located in the main urban area or its vicinity, and it is extremely difficult to increase the land use. Therefore, they need to be renovated on the basis of retaining the original structures as much as possible. The clear water tank is generally one of the structures with a larger area in the plant area. If the existing clear water tank can be retained and the insufficient part can be supplemented by a new clear water tank, this goal can be achieved, and the project investment can be greatly saved.
