糞尿 및 都市 固形廢棄物에 依한 堆肥化의 實驗報告(Ⅰ)
金秀生 東亞大學校 石堂學術硏究奬勵會 1977 石堂論叢 Vol.2 No.-
In this report has experienced the Possibility and starting condition for composting of night soil and municipal refuse with a view of developing a reusable humus product. Hereby is found as followings; 1. The municipal nightsoil has C/N ratio about 4 and C=0.52GV (significance level 80% in winter season). The municipal nightsoil has to increase his C/N ratio and decrease his humidity for composting. 2. The municpal refuse in Busan has compostable matters about 20% in 1977 and has increased 2% per year as compared With 1972. 3. It is considered the best humidity for starting composting about 35% and warm development about 40-50%.

A Biodegradability test of Leachate was performed and results of the research are as follows ; 1. The Satisfactory removal efficiencies were impossible in treatment of sample L-1 (leachate only), BOD removal efficiencies with 5.9-11.8 HRTwere 62-69% in sample S-1 and BOD removal efficiencies with 6.2-12.3 HRT were 71-76 % in sample S-2. 2. Metabolism Factor(K_(m)) was calculated to be 0.3/hr in sample L-1, 0.8/hr in sample S-1 and 1.4/hr in sample S-2. 3. Oxygen Requirement of about 1.6-1.7kg O₂/kg BOD_(rm), was required in sample S -1 and that of 1.3-1.4kg O₂/kg·BOD_(rm), was required in sample S-2. 4. Sludge production of Sample S-1 was 0.37-0.51 and that of Sample S-2 was 0.41-0.57kg VSS/kg BOD_(rm).

The Purpose of this article is to suggest for water quality improvement in Korea. In order to preseve from water pollution, the synthesized plan is required urgently. It is that short-term, middle-term, long-term of measure to counter water quality management.

"소규모 하수처리"와 "폐자원의 재이용"은 왜 필요한가?
김수생 동아대학교 환경문제연구소 1986 硏究報告 Vol.9 No.3
Sewer systems are not actually available in most of Korea cities, in which city officials have tried to solve water pollution problems by means of constructing a large sized sewage treatment plant without taking sewer systems into any consideration. For this reason, there is a tendency that waste water treatment facilities for newly constructed residential areas and industrial complex are dependent upon the large sized sewage treatment pland to be constructed. In effect a high efficiency of water pollution control can not be achieved without sewer systems, and also it is not possible to construct sewer systems for the existing cities due mainly to financial difficulties and construction problems. Consequently, an urgent water pollution control in the existing cities of korea can surely be achieved in such a way that the construction of community plants with good sewer systems should be made starting from the region where the construction of sewer systems is possible, rather than the construction of large sized waste water treatment systems. When we consider the limitation of natural resourses available for human beings in future, gradually increasing social problems of waste treatment should be dealt with a basis of waste recycling from a national economic point of view. In this symposium topics concerned with those important environmental problems in korea will be focussed, and presented and discussed by all participants.
