Study on Partial Nitrification of High Concentration Ammonia Nitrogen Containing Wastewater in One PNH System

摘要：

　　In this study,PNH system with special-designed operational software was used to investigate the partial nitrification of high concentration ammonia nitrogen containing wastewater (HCAW).Activated sludge from one running ceramic membrane reactor was inoculated as seed sludge.The key parameters controlled in the system were as follows:dissolved oxygen in aerobic tank above 2 mg/L,temperature 30 ± 1 ℃,the pH during the start-up period between 7.5 and 7.6,and the pH of the improving period and steady-running period between 7.0 and 7.1.
