The application of multiple flocculant of chitosan to the treatment of different kinds of industrial wastewater has been studied. Through testing the different kinds of industrial wastewater by using this flocculant, the optimal process, pH value prescriptions, and their technical indexes and economic indexes after treating the related wastewater can all be confirmed. The treating results show that when compared with the traditional flocculant such as PAC, COD, SS and removal rate of this flocculant goes up 10% to 20%, the treating cost of this flo-cculant is reduced by 40% ～ 60%, and its second pollution decreases greatly. Therefore, this flocculant is of obvious economic and environmental benefits.
Key words： chitosan; composite flocculant; industrial wastewater; water treatment
