| Our main origin of coal and a coal chemical industry site are mostly located in the dry western region, not only in itself is very scarce water resources and to accommodate sewage capacity is very limited in these areas. In addition, the coal chemical industry itself is a high-water industry, which requires the use of waste water during the processing of coal chemical industry in a certain technology makes it possible water reuse. Coking wastewater is a typical representative of the coal chemical wastewater. This article outlines the sources and characteristics of coking wastewater, review of coking wastewater treatment technology for example:physical and chemical treatment methods of adsorption flotation and photo catalytic oxidation and biological active sludge and biofilm etc. It focuses on the biological enzyme technology and membrane bio-processor technology combined with other treatment methods in coking wastewater treatment applications. Combined where internships come up with EO-AE-A/CBR technology, and it has been a preliminary application in engineering. Jane drew a flow chart of this process and this process MBR principle and mode of operation for the corresponding instructions. Concluded the enzyme technology and membrane bioreactors in this process advantages and membrane bioreactor in the practical application of the existing problems. |
