Application of Deep-bed Denitrification Filter in Sewage Treatment
نویسندگان
چکیده
The combined process of A 2 /O oxidation ditch, high efficiency sedimentation tank and denitrification deep bed filter was adopted in Sewage Treatment Plant Hefei City to treat municipal domestic sewage. effluent quality could meet the discharge limit major water pollutants urban sewage treatment plants industrial industries Chaohu Lake Basin (DB34/2710-2016). In addition parameters design operation, effect SS summarized detail this paper. results showed that removed very well. operational demonstrated removal 74.3%,TN (92.3％) biosystem ,in which 80.0％ 12.3％ TN influent were pre-denitrif ication ditch post-denitrification filter, respectively. be used as safeguard for with external carbon source ensure less than 5 mg/L.

Effect of Filter Inhomogeneity on Deep-Bed Filtration Process – A CFD Investigation
Aerosol filtration in fibrous filters is one of the principal methods of removal of solid particles from the gas stream. The classical theory of depth filtration is based on the assumption of existing single fiber efficiency, which may be used to the recalculation of the overall efficiency of the entire filter. There are several reasons for inappropriate estimation of the single fi...

متن کاملReduction of Excess Sludge in Sewage Treatment by Ozone Application
A new process which attains both excess sludge reduction and phosphorus recovery has been developed. In this paper, characteristics of sludge solubilization by ozone were investigated in batch experiments with sludge taken from an A/O reactor supplied with synthetic sewage and several real wastewater treatment plants. Then, performance of the new developed process was investigated in a laborato...
