Abstract: A wireless power transfer system is provided. The wireless power transfer system comprises a resonator comprising a capacitor. The capacitor comprises at least two active electrodes; and a passive electrode adjacent the active electrodes and configured to encompass the active electrodes to at least partially eliminate environmental influences affecting the active electrodes and to increase the overall capacitance of the system. The resonator further comprises at least one inductive coil electrically connected to the active electrodes, wherein the resonator is configured to extract power from a generated electric field via resonant electric field coupling.

Abstract: A method for removing phosphorus includes at least the steps of: 1) placing lanthanum oxide hydrate (absorbent) into a device for removing phosphorus, and allowing sewage having a phosphorus content of less than 100 mg/L to flow through the device; 2) adding sodium hydroxide (regeneration solution of the absorbent) when the absorption capacity of the device is exhausted, and allowing the regeneration reaction to proceed for between 4 and 12 hours; and 3) collecting eluate from step 2) and recycling phosphorus.

The method for removing phosphorus is highly efficient, employs absorbent material having a large absorption capacity and low production cost. The method is simple and convenient to practice, and low in cost.
