The results show the effects of four factors on the removal efficiency of COD are in the following decreasing order: pH value,dosage of PSAF,dosage of H2O2 and FeSO4.

By applying orthogonal design,Fenton oxidation and poly(silicon/aluminum/ferric/boron) complex(PSAFB) flocculant were used to treat leachate produced during compressing municipal domestic refuse,and the treatment effects and conditions were investigated.

Study on preparation and properties of flocculant ploysilicate-aluminum-ferric containing boron;

Study on preparation of high efficient inorganic flocculant polysilicate ferrite using iron mud and its flocculation property;

Study on pretreatment of landfill leachates using polysilicate ferrite;

In order to match the requirements of water treatment engineering, considerable attention was paid to develop composite inorganic polymer flocculants during recent years, which are represented by polyaluminum silicate chloride(PAS), polysilicate ferrite(PSF) and polysilicate ferric aluminum(PAF).
