Abstract
In the sewage treatment system, it is provided that the sewage within the sewage treatment zone around the major city should be treated in the public sewage treatment system through the sewage pipe line or outside of sewage treatment zone, the sewage and the excrements should be treated by installing the individual sewage treatment facilities or the septic tank at the origin. Since the individual sewage treatment facilities works as the domestic non-point pollution source, the management and improvement measure of individual sewage treatment system is required. However, in case of individual sewage treatment facilities, as its importance is underestimated compared with the public sewage treatment facilities, its operation and management are not made systematically. In this study, the problems and the improvement direction of the individual sewage management were studied through the investigation of institutional part of the individual sewage treatment facilities. In the results of research, it was shown that the public sewage treatment facilities or performance test laboratory(testbed) should be prepared by introducing the performance test system according to the changes in the constant temperature and the load. And performing the performance test in the performance test laboratory having temperature control device should be examined. In addition, to prevent the arbitrary manipulation (adjustment of inflow, adjustment of concentration, injection of chemicals, modification of facilities, etc) of the subject sewage treatment facilities, the measure that the performance test applicant should install the test facilities at independent performance test facilities and then, the performance test should be conducted by restricting the access of related personnel should be examined.
