High-rate trickling filter method is applied to treat municipal and industrial waste-water inflowing in waste-water treatment plant, especially to treat the liquid organic wastes. In recent years, the introduction of plastic filter media has caused a variety of changes in the design and construction of trickling filters. These plastic media provide relatively large surface area per volume of packing and a high percentage of void spaces. In using these plastic media, more uniform distribution of waste-water over the entire area and depth of the media is attained and clogging problems are minimized in most cases. Therefore, this study was measured the degree of waste-water treatment by using filter medium filled with the plastic golf ball. The purpose of this study was to evaluate the performance of a trickling filter packed with plastic media and to contribute to solution of the various problems caused to waster-water treatment.

Since the amount of solid waste from construction depends mainly on its type and scale as regional development condition, the estimation of the total amount of the construction waste is actually difficult. The approximate computation of the total amount of the construction waste is able to be estimated by determining the amount of the construction waste per unit area(the unit construction waste). However, in Korea, the unit construction waste has not been set up yet. In this study, the unit construction waste, which is classified into the case of construction and the case of demolition, is established on the bases of the existing various kinds of actual data and the investigation data.

Most of biological treatment to remove contaminants in municipal wastewater have been conducted by activated sludge process. But, the process have several problems such as enormous site needed for construction of treatment facilities, unstable treatment due to limited ability to control load fluctuation, frequent sludge bulking and appearance of lots of surplus sludge. In this study, the experiments were performed through submerging biofilm of PEPP media in existing aeration tank with raw water from municipal wastewater treatment plant and then submerging PVDC and PEPP media, different from shape and chemical peculiarity in anoxic reactor. Throughout the experience, nutrient removal efficiency according to HRT, nitrogen·phosphorous removal efficiency, behavior of nitrogen and dewatering efficiency have been compared and analysed with those of activated sludge process. As the results, BOD removal efficiency according to BOD volumetric load and F/M ratio was not found any differency in two processes, but was decreased below 90% as going along the condition of high load in activated sludge process. Kinetic coefficient was K_max=1.162day^-1, K_s=53.77㎎/L, Y=0.166㎎VSS/㎎BOD_ram. and K_d=0.019day^-1. It was found that the removal efficiency, even though in aerobic condition, in biofilm process equipped anoxic reactor was higher than the one in activated sludge process within the range of 70~80%, and became better as HRT increased. Phosphorous removal efficiency was not found any differency in two processes. In biofilm process, treatment efficiency even in conditions of high load was not decreased, because the biomass concentration could be maintained in high condition compared with activated sludge process. As HRT increased, suspended and attached biomass was increased and the other hand, F/M ratio was decreased as biomass' increasing. Biomass thickness was increased from 10.43㎛ to 10.55㎛ as HRT increased and density of biomass was within 40.79∼41.16㎎/㎝^2. The results also present that the dewatering efficiency of sludge generated in biofilm process was higher than in activated sludge process, and became better as HRT increased.

본 연구는 혐기성 소화 특성을 알아보기 위하여 2차 슬러지를 대상으로 수리학적 체류시간 (Hydraulic Retention Time, HRT)에 따른 유기물 제거효과, 가스발생량 및 탈수특성등을 위한 증온 혐기성 소화실험을 수행하였다. 유기물 제거효율은 HRT에 비례하여 계속 증가하는 경향을 나타내었다. 가스 및 메탄가스 발생량은 HRT가 15이로 증가할 때 까지는 계속 증가하다가 20일에서 오히려 감소하는 경향을 나타내었는데, 이는 유기물의 제거율이 다소 둔화되면서 가스로 전환되지 않고 소화조내에 그대로 축적되었기 때문이라고 판단된다. 한편 슬러지 탈수성은 HRT 증가에 따라 양호해졌다. 상기의 결과로 2차 슬러지의 혐기성 소화시 HRT는 15일에서 유입 VS부하율이 1.09kg VS/㎥/d일 때 가장 좋은 소화 효율을 나타냄을 알 수 있었다. The objectives of this study are to investigate the effect of organic removal and the dewaterability of sludge with Hydraulic Retention Time(HRT) using secondary sludge and estimate anaerobic digestion kinetic coefficient of microorganism. As the results of tests, the efficiency of organic removal increased gradually as the HRT was increased. And gas and methane gas production was increased until HRT got to 15 days. However, at HRT 20days it was significantly lower than HRT 15days. It means that a portion of removal organic matters were accumulated in digester without gasification. In the results of value of specific resistance, dewaterability of sludge was increased proportionally as HRT increased. From the above results, on mesophilic anaerobic digestion of waste acivated sludge, the optimum digestion efficiency was found at HRT 15days with VS loading rate of 1.09 kgVS/㎥/d.

Recently, our circumstances are threatened by an accident that leakage of underground storage tank and illegal dumping of synthetic organic compounds at chemical plants and many treatment methods, Activated carbon adsorption, Ozonization, Membrane filtration and Photocatalystic oxidation, are developed to remove such a synthetic organic compounds. And it has reported that Activated carbon adsorption have a great removal efficiency to nondegradable matters and organic compounds which have a high molecular weight. Comparing with other adsorbents, Activated carbon adsorption have a worse efficiency when adㆍdesorption speed is low. Thus improved type of adsorbents was invented and one of those is Activated Carbon Filter. The purpose of this study was getting information about adsorption characteristic of phenol which can be applied Activated Carbon Fiber and Granular Activated Carbon. In detail, With comparing removal characteristics of phenol in the presence Humic Acid using Activated Carbon Fiber(ACF) and Granular Activated Carbon(GAC), it is to certify an effective application of Activated Carbon Fiber. At the range of this study, Batch test, Isotherm adsorption test and Factorial analysis, following conclusion were obtained from the results of this study. Batch test was carried to know time of adsorption equilibrum. In this study about time of adsorption equilibrium by ACF was faster than GVC's, for developed micropore of ACF. From the result of phenol adsorption test, High removal rate of adsorption is shown at pH 5. The result of Isotherm adsorption test, it has represented that the Freundlich's isotherm is most suitable one in others, that a ACF's adsorption capacity is more excellent than GAC's. Adsorption of phenol exiting humic acid is decreased getting raised humic acid concentration. Since ACF's micropore is developed at this time, an effect of high molecular humic acid is lower. Factorial analysis was carried to know about Main effect which was injection dosage of adsorbent in the range of this study.
