Polysilicate aluminum and magnesium (PSAM) was prepared by using aluminum sulfate, magnesium sulfate, sodium silicate, sodium hydroxide as raw materials. Taking domestic sewage from Xingtai Polytechnic College as processing object, the flocculation performance of PSAM and other traditional flocculants was analyzed by coagulation and agitation test. The results show that PSAM has a good flocculation performance and is superior to the conventional flocculants such as polymerization aluminum chloride, aluminum sulfate and magnesium sulfate in treating domestic sewage. |
