waste water intensity of 1.10E-2 ton/yuan/y higher than the average total waste water intensity of 3.34E-3 ton/yuan/y. The waste water multiplier of pulp and paper industry is 1.76 revealing that when its direct waste water discharge increased 1 ton, it had produced 0.76 ton more indirect waste water that embodied in intermediate product to sustain its regular production. However, the waste water multiplier of pulp and paper industry is lower than the average value of 22.11 demonstrating that the increasing of direct waste water discharge of pulp and paper industry would not exert huge influence to the total waste water discharge of the entire industrial system.
