As new electrode material, boron doped diamond (BDD) electrode has the characteristics of high oxygen evolution potential, adsorption inertia, good physical and chemical stability, thus it might be very promising in advanced treatment of organic wastewater. The strong oxidation ability of BDD electrode is mainly attributed to the hydroxyl radicals, which can degrade organics efficiently, and occupy...
In this article, bio-contact oxidation process was applied as pretreatment process to constructed wetland for solving clogging, the main problem of constructed wetland. After 50 days test, the work condition was chosen, and the stability of the COD and SS removal rate was examined. The results showed that with the HRT of 6h and aeration concentration of 0.25m3/h, the average removal rate for COD and...
Aerobic denitrifying bacterial strains were loaded by nano Fe3O4 and applied to deal with actual living wastewater. The optimum conditions and treatment effects of free bacterial strains and immobilized bacterial strains were compared. The optimum treatment conditions of free bacterial strains for wastewater were pH6.8, 30degC and 2 days of incubation time. Those of immobilized bacterial strains were...
