국내 개인하수처리시설은 불량제품의 유통과 부실시공의 우려가 끊이지 않아 오수처리시설의 계획 및 설계에 적용 가능한 단위공정별로 최소한의 기준은 필요할 것으로 판단된다. 본 연구에서 살펴본 운영실태 분석결과의 문제점 및 필요사항은 1) 개인하수처리시설 관리감독자의 교육 강화, 2) 오수처리시설 운영관리 미흡, 3) 하수처리구역 외 2 ㎥/day 미만 시설의 오수처리시설 의무화 검토, 4) 음식점 오수처리시설에 대한 관리방안 필요, 5) 기술검토결과 부적정 시설에 대한 개선안 마련이 필요하다. 또한 국내·외 개인하수처리시설 관련 지침 및 자료 등을 조사·분석하여 설계·시공 및 유지관리 가이드북을 마련할 필요성이 요구된다. As private sewage treatment facilities in Korea are constantly concerned about the distribution and poor construction of defective products, minimum standards for each unit process applicable to the planning and design of sewage treatment facilities are deemed necessary. The problems and requirements of the analysis results of the operation status discussed in this study are as follows. 1) Strengthening education of supervisor of private sewage treatment facility. 2) Poor operation and management of Sewage treatment facilities. 3) A mandatory review of sewage treatment facilities for less than 2 ㎥/day of facilities other than sewage treatment zones. 4) Necessity of management of sewage treatment facility in feedstocks. 5) As a result of the technical review, Improvement plans for Ineligible facility are needed. It is also necessary to prepare a guidebook for design construction and maintenance by investigating and analyzing guidelines and data related to domestic and foreign private sewage treatment facilities.

The residents' odor complaint is steadily increasing by odor causing from sewage system. A current drainage facilities and septic tank are included in the individual sewerage according to Sewerage Act. However, definitions and legal standards of drainage tank are insufficient. In addition, specifications and maintenance standards related to structure and size are not established. In this research, effect of drainage tank in individual sewage facilities on the odor occurrence was studied and the concentrations of $H_2S$ and composite odor were measured. From the measurements, the concentration of $H_2S$ and composite odor were 1 ppm ~ 5 ppm and 1.04 OU ~ 4.05 OU, respectively, before pump operation. Also, the concentration of $H_2S$ and composite odor were 5 ppm ~ 33 ppm and 5.10 OU ~ 35.04 OU, respectively, after pump operation. The concentration of SS in the effluent from drainage tank was ranged from 840 mg/L to 1,980 mg/L. These high concentration of SS seemed to be the major source of foul smell when high concentrated suspended solids in the public sewerage system were decomposed and then emitted. In this research, correlation coefficient ($R^2$) between $H_2S$ and composite odor before and after pumping were 0.925 and 0.918, respectively.
