          Abstract After optimizing an ideal pipe diameter, using the unconstrained maximumvalue method, the more optimized non- linear technique, we've developed a program and standardized it. We've also proved that the expenditure on the optimization of standard-size pipe diameter makes no considerable difference from that of the ideal pipe diameter. through some illustrations of the design of water distribution pipe networks. Therefore ; we can safely conclude that applying the unconstrained maximumvalue method to the water distribution pipe networks design is the more rational and Practical optimization technique.

        • 석재공장 폐수의 처리에 관한 연구

          안송엽 圓光大學校 環境建設硏究所 1995 環境建設論文集 Vol.4 No.-

          For the efficient coagulation and sedimentation of stone processing plants wastewater this paper made such tests as physical and chemical test, Jar-Test of raw wastewater and treatment wastewater by using both various coagulants and coagulation aids. The results are obtained as follows: 1. Physical and chemical test showed that Alum treatment, inorganic coagulant was highly efficient in all ways-suspended solids treatment, Turbidity, DO, BOD, COD, etc 2. Jar-test showed that positive ionic, in case of using coagulation aid after Alum treatment, had better sedimentation removal efficiency than negative ionic, organic coagulant.

          안송엽 한국수처리기술연구회 1999 한국수처리학회지 Vol.7 No.2

          This is a study on the removal of nitrogen in wastewater by the biological fluidized bed. The results obtained through varying the recycle ratio, the hydraulic retention time and the recirculation ratio between reactors showed that the organic removal efficiency and the nitrogen removal efficiency were above 93%, 88% respectively, and the denitrification efficiency was above 85% when C/N ratio and H/A ratio were above 5 and 3.16, respectively. The biological fluidized bed obtained 93% BOD removal in 48min, 87% NH₄-N removal in 32min, and 84% NO₃-N removal in each reactor. In anoxic reactor, the recycle ratio, the total hydraulic retention time and the recirculation ratio were 30, 32min, 3 at 34℃. In aerobic reactor, 40, 48min, 3 at 28℃.

          On the treatment of stone-processing wastewater an achievement case study and literature cited do not exist in the world, so the study put many hours in it. The conclusions are obtained as follows: 1. At the study development treatment plant of stone-processing wastewater are indicated few power rate, easy maintenance management and highly treatment efficiency. 2. Efficiency of agitation lead to decrease in put of polymer coagulation so economical is good.

          안송엽,김환홍,정재균 圓光大學校 環境建設硏究所 1997 環境建設論文集 Vol.6 No.-

          Among the effect parameters working on the operation of aerobic fluidized bed, and in order to clarify the removal the characteristics of the organic matters along the changes in the pH, the researcher filled two kinds of sand of different particle size (0.30mm-0.60mm) in two reactors with different section area(A), height(H), and in the state BOD loading 4.3kg-BOD_5/㎥ㆍd, DO, pH, Suspended solids of concentration, and under the fixed state of hydraulic retention time, for around 67 minutes. The test was conducted as follows. By fixing the value obtained from the above test as the optimal condition, and in the result of the test along the gradual modification of only pH from 2 to 12, more than 90% of removal rate of BOD_5 was shown between pH 5 and 11, while the concentration of MLSS was more than 8,000mg/ℓ; however, the results of the test under the pH 5 showed that the removal rate of BOD_5 and concentration of MLSS had rapidly decreased. Thus, at pH 2, it was unable to conduct a test because the microbes were totally separated.

          안송엽,김환홍,정재균 원광대학교 공업기술개발연구소 1996 工業技術開發硏究誌 Vol.16 No.-

          For decide to do optimum injection quantity of stone manufacturing wastewater, both economy and treatment efficiency experiment a result intended for a low price things of amount of the coagulant, subcoagulant and high polymer coagulant was developed the inside and outside of the country at the present, Alum+PAC, Alum+ZETAC-57 were used smaller drugs injection weight than Alum or PAC coagulant, and also the removal ratio be a great deal. But these high polymer coagulant treatment of stone manufacturing wastewater, be estimated the most compatibly. When high removal ratio be expressed to the circumstances injection into high polymer coagulant PAC or ZEIAC-57.

          A numerical procedure is presented to deal with solution of unsteady two-dimensional groundwater flow in unconfined aquifer with pumping and /or artifical recharge is solved by the finite element method using the Galerkin approach and triangular elements in the X-Y plane. This computational procedure is shown to be stable and suitable for this class of problems with the aid of a digital computer.

          To make a basic plan for the facilities of wastewater treatment plant, the conclusion was as the following : By using the data of precipitation, I derived the intensity of rainfall 원문참조 for the five years of return period. I know that Talbot form is most suitable among several rainfall intensity formula. And I also looked into the water passage ability or existing drainage. The size of treatment facilities are adequate to determine the planning average daily amount of sanitary sewage as 1,700m3/day and planning maximum hourly amount of sanitary sewage as 3,600m3/day. The precipitations of 10rninutes and 60 minutes are 23.7mm and 49.9 mm separately.

          To make a basic plan for the facilities of wastewater treatment plant of Wonkwang University, the conclusions was as the following : The results from the analysis of the characteristics of the wastewater areas follow: BOD 100mg/l: COD 70mg/l: Ss70mg/l: pH 6.8 We schematized and presented a contact stabilization system as a model wastewater treatment Plant after applying the value of design parameter presumed by the above mentioned wastewater. The capacity of each tank showed us considerable change as the value of design parameter varied. Consequently, when we practically carry out wastewater treatment plant, we will have to do so after we redetermine the capacity of each tank, applying the value of design parameter in accordance with the characteristics of the wastewater at that time.
