According to the purifying power generation system, when the water collecting tank is full filled with water, the infrared valve is opened, reclaimed water inside the water collecting tank enters the water turbine through the power generation pipeline for power generation; when the water inside the water collecting tank is wholly discharged, the infrared valve is closed, and water is collected again. The purifying power generation system disclosed by the invention can carry out power generation by sufficiently utilizing domestic sewage generated by high-rise residents, not only can thoroughly purify sewage, but also can increase the power generation efficiency.

The invention discloses a method for calculating the theoretical water inflow of a secondary water supply tank. The average outflow and maximum outflow of water in different time periods on working days or rest days; 3. Calculate the theoretical water retention of the water tank at the beginning of different time periods in a working day or rest day; 4. On working days or rest days At the beginning of each time period of a day, calculate the theoretical water inflow of the water tank in different time periods of the day on working days or rest days based on the theoretical water retention, real-time water retention and the maximum water storage capacity of the water tank. The invention can accurately control the residence time of the tap water in the water tank under the premise of meeting the requirement of water use, and effectively reduce the risk of exceeding the standard of microbial indicators caused by the excessive residence time of the tap water in the water tank.

The invention relates to a cement-based material underwater grouting or mud-jack rock block foundation construction method and belongs to hydraulic cement-based material underwater foundation structure construction methods. A forming gabion is used for forming or the excavation boundary of a foundation serves as the outline, chicken girt concrete with the good fluidity and the high sand ratio is poured into a paving rock block stacked body or gaps of the paving rock block stacked body is filled with the chicken girt concrete by means of the self-leveling performance of the chicken girt concrete underwater, and thus underwater cement-based material grouting rock block or mud-jack rock block structure construction is achieved. The cement-based material underwater grouting or mud-jack rock block foundation construction method has the advantages that when underwater grouting or mud-jack rock block foundation construction is conducted and the water depth is smaller than one meter, construction can be directly carried out without draining water, and thus the construction progress can be greatly accelerated and the construction cost is reduced; when the method is used for reservoir risking obviation and reinforcement construction, the water drainage amount can be greatly reduced, and the construction can be completed on the premise that the effect that water is stored as much as possible is effectively ensured.

The invention discloses a water intake device for a river bed of a power plant, which includes a water inlet, a storage tank and a water intake pump room, the storage tank is arranged between the water inlet and the water intake pump room, and the water inlet and the water intake pump room The adjustment and storage tank is connected, and a grit settling area is provided near the water inlet in the adjustment and storage tank, and the grit settling area is in communication with the adjustment and storage tank. The river bed water intake device of the power plant is provided with a storage tank between the water inlet and the water intake pump room, and the water flowing in from the water inlet will first enter the storage tank, and the water storage capacity of the storage tank is guaranteed during application to meet the needs of the power plant. Long-term continuous water supply safety requirements; and by setting up a sand settling area, the raw water taken from the water inlet can be pre-sedimented at the first time, which greatly improves the quality of the raw water entering the storage tank and the subsequent water intake pump room during the flood period. Reduce the difficulty of overall cleaning and maintenance of the water intake device. During maintenance, it is only necessary to focus on cleaning the sand settling area.

The invention provides a system for controlling silt deposition in a river channel. The system comprises an acceleration section and a deposition section which are located in the river channel, wherein a river channel width D1 of the acceleration section is smaller than a river channel width D2 of the deposition section; a deposition tank is arranged in the deposition section; a slit collecting and dredging device is arranged in the deposition tank. The invention also provides a method for controlling silt deposition in the river channel.
