| Abstract |
As regards to the cost on installation and operation of the waste water treatment facilities, the objective 436 companies from 34 kinds industries registered to Environment Administration, the Government Office of Korea from 1984 to 1985, were analyzed. The results were as follows: 1. The biological treatment method was applied to about 80% in the food and food products industries, the chemical treatment about 90% in metal machinery, plating, chemical products manufactures, and the consolidated treatment about 90% in the leather, paper and textile industries. 2. Average cost of the installation for the waste water treatments required US$ 979.11 per ㎥ of facility for the capacity of treatment plant less than 100 ㎥/day, US$ 299.79 per ㎥ for the capacity of treatment plant less than 1,000 ㎥/day, and US$ 56.14 per ㎥ for the capacity of treatment plant less than 10,000 ㎥/day, respectively. It was shown that the greater the capacity of treatment required, the less the installation cost per the unit facility capacity. The installation cost can be expressed as a function of the concentration of BOD and scale of treatment facilities. Formula was as follows; Y_J = -1836.183 1/log_(l0) BOD + 2094.022 1/log_(l0) S where, Y_J : installation cost, 10³ Won/㎥ -day S : capacity of facilities, ㎥ -day |
