Combined with the practical experience of wastewater treatment plant, the chemical coagulants have inhibition effects on microorganism activity, with the influence degree of PAC (polyaluminium chloride) > AlCl3> Fe2(SO4)3. In synchronization dephosphorization, the inhibition rates of PAC in 10 ppm and 20 ppm are 11.9% and 33% respectively; while the inhibition rates of AlCl3 and Fe2(SO4)3 in 20...

Phosphorus-containing converter slag is a common waste in the iron and steel industry, has characteristics of high generation low secondary-utilization values; however, high-phosphorus content limits its ability to be recycled during steelmaking process. In this study, dephosphorization behavior by carbothermal reduction was studied through experiments thermodynamic calculations. The results sh...
