Experiment Research of Solar Energy Ozonizer Used in Sewage Treatment

Abstract:

The device is composed of solar battery, power automatic switching, high pressure booster inverter, dielectric-barrier discharge type ozonizer, air compressor and microporous aerator components, whicn is powered by the double power suppl y modes including the solar battery and the city electricity. In the conditions of insufficient illumination or rainy weather, power can switch to the city electricity automatically. The article introduces the composition and working principle of solar ozonizer. The experiment is respectively done in the sample of the second phase of water from BaoDingYingdingzhuang sewage plant, the urban river water and the dyeing effluent with 1500 ml.The power of the solar energy ozonizer is 18W and ozone production is 25 mg/min. The experiment results show that the removal rate of Fecal coliform, Chroma and Chemical Oxygen Demand (COD) are obviously improved. Especially, the removal effect of Fecal coliform and Chroma is very significant. The experiment indicates that the content of NH3-N has increased with the growth of ozone contact time.
