| Summary: | 碩士 === 中原大學 === 環境工程學系 === 106 === Dihua Sewage Draw Water Station and Dihua Sewage Disposal Plant , the both them are the biggest in Taipei. We call them with Dihua. The Trash Rakes are the first process while Dihua treat domestic sewage. And then , the filter residue produced may contain many unknown germs. The filter residue mainly contains larger organic substances such as feces or kitchen waste.
The biological treatment procedures in the sewage treatment process can be divided into aerobic treatment and anaerobic treatment. Aerobic treatment is to decompose organic matters in wastewater or wastes by through microorganisms under aerobic conditions, and convert them into final products such as water, nitrates, and carbon dioxide; while anaerobic treatment is the decomposition of organic substances by microorganisms under anoxic conditions. It is decomposed into water, carbon dioxide, methane, hydrogen sulfide, and other final products. There are many kinds of volatile organic compounds, and the sources are complicated. Various VOCS are released due to microbial reactions from the biological treatment procedures. Have a disgusting smell, and Dihua treatment of odor is deodorized by 12 two-stage wet scrubbers.
This study is designed to return this waste energy to the wind turbine module by wind power from the wet scrubber. Implementing waste energy recycling. A horizontal axis wind turbine was built with a DC motor to generate electricity and drive the ceramic corona method to produce ozone. The wind speed discharged from the wet scrubber was tested. The voltage, current, and speed generated by the wind energy generator. Power analysis through by O3 generated by the module, and then how many VOCS are removed.
In the laboratory, the ozone generator in the 40.5L module need 12V voltage and 1A current to produce ozone 34 ppm/min. Ozone is then degraded to toluene to obtain a removal rate of 83%. Wind power generation in the Dihua two-stage scrubber exhaust vents for wind field testing. The maximum wind speed of the exhaust vent during the test is 14m/s. And the motor revolutions up to 1570 rpm. The average wind speed of the average exhaust vent is 12.9 m/s. And the average number of motor revolutions reaches 1503 rpm, which can generate 15.39W of electricity. The wind power generation in the test has reached 12.31V 1.25A ampere, which is enough to drive the wind ozone generator of this study.
