摘要: The present invention relates to a method for acquiring the water leakage amount of a leakage area in a water distribution system. In the method, a hydraulic model is coupled with monitored data, and the water leakage amounts of different areas in the water distribution system are obtained through inversion by optimizing the spatial distribution of water leakage amounts. In addition to the coupling of the hydraulic model with the monitored data, virtual sectorization and pipe leakage risk assessment are used. By using a minimum difference between a simulated value and a monitored value at a pressure measurement point as a target, the water leakage amounts of different areas in the water distribution system are calculated by an optimization algorithm. Compared with the prior art, the present invention actualizes the effective identification of leakage areas in a water distribution system with a high leakage rate (i.e., with many leakage points).

摘要: A thin-film composite polyamide reverse osmosis membrane with anti-bacterial and anti-biofouling effects and a preparation method thereof are disclosed. The preparation method includes: dissolving a highly water-stable metal organic framework CuBTTri in an n-hexane solution containing trimesoyl chloride by ultrasonic wave, immersing a polyethersulfone ultrafiltration membrane in an aqueous solution of m-phenylene diamine and taking out, and then immersing the ultrafiltration membrane in the trimesoyl chloride-n-hexane solution containing the aforementioned metal organic framework for reaction and modification, so as to obtain the thin-film composite polyamide reverse osmosis membrane. The resulting composite reverse osmosis membrane integrated with the anti-bacterial metal organic framework CuBTTri has a high reverse osmosis membrane permeability and possesses greatly improved and persistent anti-bacterial and anti-biofouling properties. The preparation method is simple and conducive to promotion, and has mild conditions.
