The results show that the Tx-1 dosed system can obtain good effluent characteristics while minimizing sludge production and energy consumption. The total phosphorus（TP） is lower than0. 5 mg/L in effluent without any chemical regent added. The discharged dry sludge per 10 000 m^3 wastewater Dwat decreases from 1. 4 to 0. 5 t. For per cubic meter wastewater, the air supply decreases from 6. 0 to 5. 1 m^3 and the electricity consumption decreases from 0. 412- 0. 425 kW·h to 0. 331 kW·h. The addition of Tx-1 can improve the substrate removal constant and decrease the microorganism growth yield coefficient of activated sludge. At the same time,the structure of the microbial community changes and the biodiversity increases by adding Tx-1. The abundance of polyphosphate accumulating organisms（PAO）, Comamonadaceae and Tetrasphaera, increased. Effective microbial agent is a potential way to combine in-situ sludge minimization with contaminants removal.展开更多
