Patent number: 11739015Abstract: The disclosure belongs to the field of sewage treatment technology, in particular to a low-carbon nitrogen and phosphorus removal system and process for sewage treatment. The system of the disclosure includes a primary sedimentation fermentation tank, a mainstream modified A2O unit and a bypass anammox unit. The disclosure sets a denitrification phosphorus removal functional zone in the anoxic tank of the A2O system, and sets a deoxygenation zone in the aerobic tank. Combined with the primary sedimentation fermentation tank, the efficient utilization of the carbon source of the A2O process is strengthened. The system has good effluent quality and does not require the addition of a carbon source, and the aeration energy consumption is low, which achieves efficient and low-carbon nitrogen and phosphorus removal.Type: GrantFiled: March 2, 2023Date of Patent: August 29, 2023Assignee: NORTH CHINA MUNICIPAL ENGINEERING DESIGN & RESEARCH INSTITUTE CO., LTD.Inventors: Xingcan Zheng, Qiongqiong Xia, Pengfeng Li, Yongli Sun, Wei Shang, Wenan Zhang, Yaxiong Wang

Patent number: 8755903Abstract: The present invention discloses a functional electrical stimulation system comprising a primary power, a boost module, an energy storage section, an output control relay, an automatic discharge circuit, a foot/hand controlled switch, a current detection chip and a current limiting fuse. The boost module comprises n DC chopper circuits connected in series, and outputs a high voltage of 100-200V. According to an enable signal and a current detection signal, the output control relay disables/enables the DC boost module. The automatic discharge circuit discharges capacitance of the energy storage section automatically when the relay turns off the power input. The Foot/hand controlled switch, the current detection chip and the current limiting fuse form a triple accident protection circuit. The functional electrical stimulation system maximizes the intensity of electrical stimulation within the range that the human body can withstand.Type: GrantFiled: June 28, 2011Date of Patent: June 17, 2014Assignee: Institute of Automation, Chinese Academy of SciencesInventors: Zengguang Hou, Min Tan, Yixiong Chen, Pengfeng Li, Hongbo Wang, Long Cheng, Guoqing Hu, Qingling Li, Feng Zhang, Jin Hu, Xinchao Zhang, Yi Hong, Junwei Zhang, Jinzhu Bai, Zhen Lv
