TL;DR: Sludge reduction and enhanced nutrient removal could be achieved simultaneously in the proposed system and the total nitrogen and phosphorus removal efficiencies reached to 80.1% and 90.0%, respectively.

TL;DR: In this paper, a sequence hybrid biological reactor (SHBR) was proposed, and some key control parameters were investigated for nitrogen removal from wastewater by simultaneous nitrification and denitrification via nitrite.

TL;DR: The results clearly showed that sludge acidification rate in fermentation reactor can reach to 43.2% and that, when the H-A-O pilot-scaled reactor was operated continuously and sludge fermentation liquids were applied as additional carbon source in the A-O reactor, the removal efficiencies were higher than 90, 95 and 79%, respectively.

TL;DR: In this article, a sludge carbon source two-stage alkaline hydrolysis acidizing recovery method is proposed to solve the problems that the carbon source in a sewage treatment plant is deficient and the sludge treatment is difficult and belonging the field of sludge and sewage treatment technology.

TL;DR: It was found during the research process that high phosphorus and nitrogen removal efficiency can be simultaneous achieved without anaerobic and anoxic phase, which was conventionally considered as a key phase for phosphorus andnitrogen removal.
