Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. use. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection.

At present, the environmental protection water treatment industry is more and more involved. In the process of sponge city construction, ecological water purification and reuse technology is an indispensable part. Because some areas will build some initial rainwater storage facilities in the process of sponge city construction , and some of the intercepted initial rainwater needs to be treated by ecological purification before it can be discharged or re-stored for use. During the non-rainfall period, the regulation and storage facilities and ecological purification facilities will be vacant and out of operation. The purification treatment of the facilities will play a certain role in improving the water quality of urban rivers.

However, most of the existing water replenishment technologies in China are controlled by electric valves and liquid level gauges, so the complexity of such control is high both in construction and maintenance. However, the lever-type float valves on the market in the past have limitations in terms of space requirements and water replenishment control. In particular, they require sufficient water pressure to open, making it almost impossible for rivers with low water levels to replenish water in the pool. Therefore, the installation space of the lever type float valve is limited, and it cannot be started with zero pressure.
