Experimental Study On RBS Method Of Sewage Treatment

As a new wastewater treatment technology, RBS technique has drawn increasing attention. The technique utilizes the natural life activities of soil bacteria decompose organic pollutants in sewage removal, purify effect. As the RBS technique has a high concentration of high-quality water treatment, efficient denitrification to the scales, suppressing the generation of odor and many other advantages, gradually caused widespread concern in the community.In this paper, given the current development at home and abroad RBS technology, summary evaluation of the RBS treatment technology and process characteristics, And municipal sewage treatment system conducted field visits and research, are familiar with the characteristics of sewage water, determined using RBS technology as sewage treatment process.Through the treatment process of debugging and RBS studies to determine factors RBS process. According to the experimental data, its analysis, summarized fluctuations each processing unit performance, and ultimately determine the optimum operating parameters RBS system handles domestic sewage. Considering, RBS process sludge acclimation time should be controlled at about12d for the best, and its activity is high, stable sludge nature; suitable for a large number of soil bacteria growth and reproduction of the environment should be controlled pH level of about7.0; effluent concentration should be controlled in the1900mg/L or less. COD removal rate could reach above95%; optimum aeration time is8h.
