The present application provides a voltage conversion circuit based on reconfigurable switched-capacitor converters and a system-on-chip, and relates to the field of on-chip power supply technologies. The voltage conversion circuit comprises a plurality of reconfigurable switched-capacitor subcircuits and an array of gate driver circuits. Each reconfigurable switched-capacitor subcircuit comprises a power switch array and a plurality of flying capacitors, wherein the power switch array comprises a plurality of power switches. A control terminal of each power switch in the power switch array is connected to an output terminal of the gate driver circuit array. Each flying capacitor is connected, through the power switches in the power switch array, to a target location in the system-on-chip so as to form a plurality of charge-transfer paths. In response to drive signals output by the gate driver circuit array, the power switch array selectively turns on different combinations of power switches to provide multiple voltage conversion ratios. The present application simultaneously achieves a wide range of voltage conversion ratios, fine-grained voltage regulation, and high efficiency.

A method and application for improving anaerobic ammonium oxidation performance based on stimulating cell envelope stress [Granted Patent]
一種基於刺激細胞包膜應力提升厭氧氨氧化效能的方法和應用 [授權專利]

Technology Field(s):
環境技術 Environmental technology
The present invention discloses a method for enhancing the performance of anaerobic ammonium oxidation (anammox) by inducing cell-envelope stress, and an application thereof, relating to the field of water treatment technologies. The method employs a pulse-dosing mode to add an envelope reagent, thereby inducing envelope stress in anammox bacteria. Continuous addition of the envelope reagent may cause severe sludge flotation, whereas pulse dosing provides sufficient time to balance the lipid removal rate of the envelope reagent with the lipid synthesis rate of the anammox cells. This ultimately enhances anammox performance and improves nitrogen-removal efficiency. The method is suitable for wastewater treatment facilities that cannot provide sufficient mixing intensity or that contain dead zones. It partially replaces mechanical mixing with chemical stimulation, thereby preventing inefficient and unstable anammox operation, and has broad potential for application.
