Effect of different carbon sources on performance of an A

Dongliang Du, Chuanyi Zhang, Kuixia Zhao, Guangrong Sun, Siqi Zou, Limei Yuan, Shilong He

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 2, doi: 10.1007/s11783-017-0981-z

Abstract: Effect of different carbon sources on purification performance and change of microbial community structure in a novel A N-MBR process were investigated. The results showed that when fed with acetate, propionate or acetate and propionate mixed (1:1) as carbon sources, the effluent COD, NH -N, TN and TP were lower than 30, 5, 15 and 0.5 mg·L , respectively. However, taken glucose as carbon source, the TP concentration of effluent reached 2.6 mg·L . Process analysis found that the amount of anaerobic phosphorus release would be the key factor to determine the above effectiveness. The acetate was beneficial to the growth of associated with biological phosphorus removal, which was the main cause of high efficiency phosphorus removal in this system. In addition, it could eliminate the associated with glycogen-accumulating organisms and guarantee high efficiency phosphorus uptake of phosphorus accumulating organisms in the system with acetate as carbon source.

Bi-modes alternation stepping ultrasonic motors

JIN Jiamei, ZHAO Chunsheng

Frontiers of Mechanical Engineering 2008, Volume 3, Issue 1,   Pages 101-105 doi: 10.1007/s11465-008-0018-1

Abstract: Based on the principle of alternative operation of two bending vibration modes in an annular stator, this paper presents a standing-wave stepping ultrasonic motor characterized by no accumulative errors driven by an open-loop control circuitry. The driving forces are generated from the motions of projections on the stator in two modes. The positioning of the motor is achieved by the cooperation between the stator projections and rotor teeth, and the number of the rotors determines the stepping angle of the motor. Two-phase sinusoidal signals corresponding to the two modal frequencies drive the motor bi-direction stepping rotation via a switch unit. The prototype runs steadily without miss-step on trial. The single-step angle displacement of the motor is 2.5°.
