| Notes | Zou Haiming, Lu Xiwu （1. College of Resource and Environment, A nhui Science and Technology University, Fengyang 233100, China; 2. School of Energy and Environment, Southeast University, Nanjing, 210096, China） wastewater treatment; nitrogen removal; crystallization; denitrifying nitrogen and phosphorus removal; phosphorus recovery 11-2047/S Generally, it is unsuitable for treatment of domestic wastewater with a low C/N ratio by conventional wastewater treatment processes due to the lack of carbon source in sewage, probably leading to not meeting the A in first-grade sewage effluent discharge standard of GB18918-2002. For this, development of an economic and environmental friendly process for treating of domestic wastewater is urgent, which may provide a benefit for development of wastewater treatment technologies and enhancement of water environmental quality. Moreover, phosphorus is a non-renewable resource and the quantities of mineral phosphorus resources are rapidly decreasing in the world due to increase i |
