Compared with the composite flocculant of WuHan petrochemical factory, its capability is superior to it: the efficiency of eliminating CODCr and SS are 28.75%and 8.29% respectively higher than those by flocculant of WuHan petrochemical factory, but the cost is46.63% lower; which is also far lower than the current average cost of petrochemical industry wastewater treatment. When dealing with papermaking wastewater, it can fully meet the require that WuHan ChenMing paper industry group put forward: The efficiency of eliminating CODCr higher than 25% based on the chemical cost controlled in 0.5 Yuan/ton sewage so as to better the gas float section. Those studies preparatorily show that this composite flocculant has particular effect and obvious economic、environmental benefit in industrial effluent treatment
