| Abstract: | This article describes the results of study on preparation of polysilicic acid containing aluminium sulfate(PAAS)and its application in dyeing wastewater treatment.The optimum conditions for preparing PAAS,such as concentration of sodium silicate,pH,Al_2O_3/SiO2 and so on,were selected.PAAS prepared were used to treat the model dyeing wastewater and that from the printing and dyeing mill and compared with PAC,PFS,Al_2(SO_4)_3. It shows that PAAS as a flocculant has a good effect within wide scope of pH and a little dosage in dyeing wastewater treatment and the floc produced from treatment process settles out quickly. PAAS is shown to be an excellent flocculant. |
