In this paper, Characteristics of Tunneling wastewater is high alkali about pH 11.25∼11.85, Turbidity is experimented from 2590NTU to 413NTU. On the other hand CODMn, T-N, T-P is very lower than Permissible discharge standards due to make almost particle. the optimum dosage of flocculant for tunneling wastewater with pH and turbiditiy changes. The samples were mixed rapidly(200rpm-3min) and mixed slowly (30rpm-30min), then settled(10min). The optimum dosage of aluminum sulfate is 20ml/L and Polymer is 0.4ml/L even pH changes and turbidity changes. As a result, pH changes and turbidity changes have not decisive effect on treatment water quility. Also, Biocube media is the best removal efficiency on sample 1 than other medias, The removal efficiency of particle in Biocube media on sample2 is 88% for 30min. More filtration studies of tunneling wastewater must be done.
