Aiming at the complicated control problem of the existing inductively coupled power transfer system, a self-oscillating control method for the push-pull resonant converter with parallel-series compensation is proposed. The necessity of designing the start-up circuit is explained by illustrating the principle of self-oscillating control. Based on the analysis of the energy transfer mechanism of the...
To decrease further the footprint of common anoxic-oxic submerged membrane bioreactor (A-O SMBR), a vertical structure on A-O SMBR was introduced in this paper. A nylon screen (NS) was placed in the oxic zone together with hollow fiber membrane (HF). With the reactor working, sludge flocs adsorbed on the NS surface and formed a "dynamic membrane" gradually, which could intercept pollutants...
An Anoxic/Aerobic Membrane Bioreactor (A/O-MBR) system have been developed to improve the efficiency of nutrient removal. The important factors those system are the ratio of anoxic zone/aerobic zone (VA:VO), internal recycle rate (IR) and solids retention times (SRT). The optimal ratio of anoxic zone/aerobic zone was 1:3. The IR ratio and SRT for effective nutrient removal were 300% and 30d, respectively...
This experiment used A/O industrial filter cloth self-forming dynamic membrane reactor to treat campus domestic sewage, COD removal rate of the effluent was 91%, NH3-N and TN removal rate of the effluent was 92.4% and 88.1% respectively, the average turbidity of the effluent was 2.31NTU. The test results showed that the A/O industrial filter cloth self-forming dynamic membrane reactor had good effect...
