The sludge settling characteristic is satisfying with SV varying from 22 to 30 and SVI varying from 58 to 80ml/g.The sludge bulking problem has been avoided successfully. The excess sludge can be thickened to 3%-4 %. The alkalinity remains equilibrious between the nitrification and denitrification in SBR-BAF system. The COD and TP loading of SBR are 2.08kgCOD/kgMLSS·d and 41.68gTP/kgMLSS·d, respectively. The NH4+-N loading of BAF is 1.16kgNH_4~+-N/m~3.d. The total HRT is about 10 hours which is only about half of suspended growth process for simultaneous phosphorous and nitrogen removal. Under the above mentioned high loadings and short HRT, the mean removal efficiency of COD, TP, NH4+-N, TN is 96%, 98%, 93%, and 84%, respectively. The mean effluent concentration of COD, TP, NH4+-N, TN, SS is 20mg/L, 0.23 mg/L, 3.24 mg/L, 7.68 mg/L, 5 mg/L respectively, which means every index can meet the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.
