Abstract
The results in this study show that this system exhibits satisfactory reduction efficiency in BOD, NH3-N and T-P. However, its performance for SS is relatively poor. Although the overall reduction rate is not that outstanding, the effluent after the treatment with this system can meet most criteria of the Effluent Regulation Limits set by EPA Taiwan. It reveals that this system do have potential in depleting pollutants from the household sewage. The input concentration of effluent is closely related with the reduction rate. Also, there is an interdependent relationship between the pollution loading and the reduction amount. It implies that, within assimilative capacity of the system, a higher pollution loading will generally results in a better reduction rate. While this system may not be suitable for the metropolitan areas in Taiwan for their high density of population and land utilization, but it does work well in the remote areas such as the suburb, village and so on, where there are no sewage sewer system available. It may act as a substituting treatment facility for the household sewage. Also, as this system is installed in the underground, for the cases that larger land is available and light development is permitted, it is possible to cultivate the lands for amusement parks, agricultural pastures, schools and so on while leave the function of the major objects undisturbed.
