Abstract
|
|
|
The pilot plant experiment was performed to investigate phosphorus and nitrogen removal from domestic wastewater by
MLE process combined with aluminum corrosion reactor. When operating 0.5Q and 1Q to internal recycle and sludge recycle in the MLE process, the effluent CODMn concentration of internal recycle 0.5Q were higher than internal recycle 1Q, the removal efficiency rates of NH3-N in the internal recycle 0.5Q were was higher than internal recycle 1Q. Denitrification rates were about 86.8% in internal recycle and sludge recycle 0.5Q. When operating 0.5Q to internal recycle and sludge recycle in the MLE process, the removal efficiency rates of total nitrogen was the highest. The removal efficiency rates of total phosphorus was about 91.5% in the aluminum corrosion reactor.
