ABSTRACT In this study, a vertical subsurface flow (VSF) stormwater wetland having partially submersed zone in the bottom was operated for 90 d. This is designed to recycle effluent on basis of designated antecedent dry days (ADDs). A total four groups bench-scale VSF wetlands filled with different media such as woodchip, pot gravel, synthetic fiber and volcanic stone were made. Each group same scheme. Operational results show that at beginning operation about 30 d, there maturation or...
Abstract The performance of four different types filter media, namely woodchip, pot gravel, synthetic fiber, and volcanic stone employed as the main media in a set column vertical flow stormwater wetlands were evaluated this study. evaluation parameters treatment performance, adsorption capacity, porosity, filtration type, plant growth, substance release, cost, construction. For pollutant removal, all showed efficient reduction total suspended solids (more than 80%). Similarly, organics...
This study was conducted to develop a vertical subsurface flow (VSF) wetland remediation system packed with woodchips control stormwater pollution arising from livestock agriculture. Three lab-scale VSF wetlands were operated recirculation during the interval (Δ) between storms as 2, 4 and 8 days, respectively. The fed water 100% recirculated one time per 24 h; frequency 1, 3 7 times at Δ of constructed systems proved be effective in reducing total suspended solid (TSS), but also had...
Three pilot-scale compact constructed wetland systems were to treat stormwater from a highway. They each comprised sedimentation tank, and vertical flow (VF) bed equipped with recirculation device. The VF beds filled woodchip, pumice volcanic gravel, respectively. According the analysis of particle size distributions (0.52–500 μm), predominant particles in ranged 0.52–30 μm. In 24 h settling time, efficiencies increased increasing size. beds, further capture was achieved; however, woodchip...
Abstract Results of water quality analysis indicated that the outflow from a hydrocyclone treating road runoff still requires further treatment before discharging into receiving waters. Hence, several designs were presented for post-treatment (including pollutant-concentrated underflow and pollutant-separated overflow). The design criteria based on some main affecting factors, such as level, land availability, construction cost. With respect to determination goal, primary consideration...
A half-saturated pilot-scale wetland planted with Acorus calamus was built to treat urban stormwater. The design comprises a sedimentation tank for pretreatment, and vertical flow volcanic gravel bed equipped recirculation device. Eighteen rainfall events were monitored in 2012. treatment system achieved total removal efficiencies of 99.4, 81, 50, 86% suspended solids, organic matter, nitrogen phosphorus, respectively, 29, 68, 25% copper, zinc, lead, at 3-day hydraulic residence time. In the...
The test site locates in the subsidence area of Panyi colliery, Huainan city, and flyash used come from Tianji power station. Three different covering thickness fields are designed, including 20cm, 30cm 50cm. Indexes chosen as follows volume weight, texture, moisture content, pH, organic matter, total nitrogen, available phosphorus rapidly-available potassium. variation soil physical-chemical properties is analyzed. Test results show that, texture silty loam, capacity holding water good;...
우리나라에서는 유역 특성별 비점오염물질 유출특성을 파악하고 최적관리방안을 도모하기 위해 2000년 이후 다양한 형태의 실험실 규모 또는 실증 최적관리방안(Best Management Practices, BMP) 시설에 대해 연구가 진행되고 있으나 특성상 자정작용의 기회가 주어지지 않는 연안지역에서의 유출특성 및 관리방안에 대한 연구는 미비한 상태이다. 최근 연안지역 개발에 따른 불투수층 비율은 지속적으로 증가하고 있으나, 초기우수의 직접유출을 방지하기 위한 완충 시설 최적관리방안 시설은 전무한 본 논문에서는 충남 보령시 대천항 주차장을 중심으로 연안 지역의 파악하고, 이를 저감하기 설정하여 비점오염원 관리에 기초자료를 제공하였다. 연안지역은 지역특성상 해안과 접하고 있기 때문에 지하수위가 낮고 경사차가 크지 않은 평탄한 지형을 이루고 있다. 즉, 선정하는데 있어 유출입구의 수두확보문제와 굴착 깊이에 제한을 받으며, 인공습지 저류지와 같은 대규모 저류형 시설의 입지조건으로는...
The function of vertical subsurface flow wetlands can potentially be reduced with time due to clogging and are often assumed occurring when ponding overflow is observed during rainfall. To investigate their potential, three pilot-scale (VSF) wetland systems were constructed employing woodchip, pumice, volcanic gravel as main media. received stormwater runoff from a highway bridge for seven months, after which the media taken out divided into layers determine amount characteristics...
This study assessed the contribution of emergent vegetation (Phragmites australis, Typha latifolia, and Nelumbo nucifera) to submerged surface area, amount biofilms attached portions plants, treatment performance a free water (FWS) constructed wetland. Results showed that 1% increase (31 m2) in vegetative area resulted an 220 m2 0.48 kg Volatile Suspended Solids (VSS) biofilm. As coverage increased, effluent organic matter total Kjeldahl nitrogen decreased. Conversely, higher nitrate...
