Abstract

The model investigations of sewage purification were carried out in a medium sand bed with an assisting hydro-anthracite layer with thickness of 0.10 and 0.20 m. It has been observed that the effectiveness of sewage purification related to basic qualitative parameters (total suspended solids – TSS, BOD5, COD, total nitrogen, total phosphorus) is in accordance with the Polish standards on sewage disposal into grounds and surface water. It has been stated that the medium sand soil bed with the 0.20-meter thick assisting hydro-anthracite layer shows higher effectiveness of sewage purification than the 0.10 m thick assisting layer. This application in the medium sand soil bed increased the removal efficiency regarding TSS by 3.1%, total nitrogen by 29.4%, ammonia nitrogen by 1.2% and total phosphorus by 23.0%, and reduction efficiency regarding BOD5 by 1.5% and COD by 11.3% with relation to the 0.10-meter thick assisting hydro-anthracite layer (all percentages – in average). The investigations confirm that the hydro-anthracite with the granulation of 1.8–2.5 mm can be used to assist in removal of nitrogen and phosphorus compounds from sewages

含无烟煤支撑层的中砂污水处理效率模型研究

污水净化的模型研究是在中砂床上进行的，并辅以厚度为0.10和0.20 m的水无烟煤层。据观察，污水净化的有效性与基本定性参数(总悬浮物- TSS, BOD5, COD，总氮，总磷)有关，符合波兰对污水排放到地面和地表水的标准。已有研究表明，0.20 m厚辅助水无烟煤层的中砂土层比0.10 m厚辅助水无烟煤层具有更高的污水净化效果。与0.10 m厚的助水无烟煤层相比，在中砂土层中应用该方法对TSS、总氮、氨氮和总磷的去除率分别提高3.1%、29.4%、1.2%和23.0%，对BOD5和COD的去除率分别提高1.5%和11.3%(所有百分比均为平均值)。研究证实，制粒1.8 ~ 2.5 mm的水无烟煤可用于辅助去除污水中的氮磷化合物

期刊介绍： Scientific Review Engineering and Environmental Sciences [Przegląd Naukowy Inżynieria i Kształtowanie Środowiska] covers broad area of knowledge and practice on fields such as: sustainable development, landscaping of non-urbanized lands, environmental engineering, construction projects engineering land management, protection and land reclamation, environmental impact of investments, ecology, hydrology and water management, ground-water monitoring and restoration, geotechnical engineering, meteorology and connecting subjects. Authors are welcome to submit theoretical and practice-oriented papers containing detailed case studies within above mentioned disciplines. However, theoretical papers should contain part with practical application of the theory presented. Papers (in Polish or English languages) are accepted for publication after obtaining positive opinions of two reviewers. Papers published elsewhere are not accepted.
