금속 Cd(II), Cu(II) 및 Pb(II)의 Trien-OH 계에서 ion강도 0.1, $25^{\circ}C{\pm}1$일때 혼합착물에 대한 안정도정수를 폴라그래프에 의해 구하였으며, 이들 혼합착물의 pH변화에 따른 분포상태를 컴퓨터로 계산하여 검토하였다. 또한 Cu(II)와 Cd(II)를 분리하기 위해 양ion 교환수지상에서의 조건분배계수이 이론식을 안정도정수를 이용하여 유도하였으며, pH변화에 따른 Cu(II)와 Cd(II)의 분리최적조건은 pH 9.0이상임을 알았다. EDTA를 가리움제로 하여 Cd(II)-Cu(II)-Trien-EDTA계에서 실험조건을 pH 11.0로 하고 Cu(II)를 Cd(II)로부터 분리한 결과는 만족할만 하였으며 이론치와 잘 일치하였다. The formation constants of the mixed-ligand complexes in the Cd(II), Cu(II) and Pb(II)-Trien-OH system were studied by polarograph. The formation constant $(log{\beta}_{ij})$ was determined at $25^{\circ}C$ in the ionic strength of 0.1. It was also confirmed that the mixed ligand complexes in this system were formed above pH 10.2, 10.5 and 9.0 for Cu(II), Cd(II) and Pb(II) by the calculation of the distribution for complexes at the various pH. Masking of Cd(II) by conversion to anionic EDTA-complexes has been used to separate Cu(II) from Cd(II) through passage of a combined Trien-EDTA solution on an cationic resin column. The optimal condition for the separation of Cu(II) from Cd(II) is confirmed at the pH range above 9.0, not only by considering the theoretical equation of the conditional-exchange-constant of metal on the cation exchange resin,but also by calculating the distribution of the mixed ligand complexes in the resin at the various pH with computer. By analyzing the synthetic sample of Cu(II) and Cd(II) with a EDTA masking at pH 9.5, it is found that the results of the experiment are satisfied with the theoretical value.

In this study, a method of treating waste water from the Bisan Dyeing Industry complex has been developed. This process will be used as a model for treating waste water from the future large-scale dyeing industy complex. If the concentrated dyeing waste water may be seperated from the scouring waste water the C-2 process is the most economical to treat the concentrated dyeing waste water first by the coagulation precipitation process and the scouring waste water mixed with the effluent of coagulation precipitaion next by the activated sludge process. When it is impossible to seperate the concentrated dyeing waste water from scouring water for the Biasn Dyeing Industry complex, the B-2 process treating by the activated sludge process following coagulation precipitation with alum can be applied.

The formation constant of the mixed-ligand complexes in the Cd(Ⅱ), Cu(Ⅱ) and Pb(Ⅱ) -Trien-OH system were studied by polarograph. The determined formation constants (log B(ij)) were follows at 25℃ in the ionic strength of 0.1: metal MT MT₂ M(OH)T M(OH)T₂ M(OH)₂T Cd(Ⅱ) 12.22 14.63 13.58 15.45 15.57 Cu(Ⅱ) 20.16 21.78 22.56 Pb(Ⅱ) 9.98 12.51 14.49 It was also confirmed that the mixed ligand complexes in this system were formed above pH 11 by the calculation of the distribution for complexes at the various pH.

This studies provided the optimization for the design treating activated sludge process for the waste water from the large-scale dyeing industrial complex. Two processes were here used to treat the dyeing waste water, which one is treated with raw waste water directly by the activated sludge process and the other treated by the coagulation follwing with activated sludge process. Design parameters as maximum specific substrate utillization rate(??) and half velocity coefficient (??) were obtained for each process. And also discussed the optimization conitions for the design of the activated sludge process with these parameters.
