摘要

生活廢水之污水處理方法常以生物處理為主，而其中去除氨氮是重要項目之一。本研究以中原大學良善樓實際運作之再生水處理槽及4個精密實驗筒進行實驗，利用甘蔗渣與椰子殼兩種材料做為處理氨氮之濾材，以其氨氮去除率、濾材殘留率及濾材放置密度為設計依據，設計一類似本研究污水再生處理系統之所需濾材量及濾材添加時距。
本研究依前期研究資料進行濾材耗損率實驗及濾材配比對氨氮去除率實驗。在實際處理槽實驗結果，在兩座處理系統之第2槽分別放置密度47.4( kg/m3)與37.0 (kg/m3) 之椰子皮濾材。第1個月時，其去除氨氮能力分別為280.9(mg/kg)；350.0(mg/kg)。至12個月時，氨氮去除率分別為72.4(%)；76.5(%)。於精密實驗筒實驗結果，養菌30天及水力停留時間1 小時，甘蔗渣及椰子皮配比1:1之濾材於污水氨氮濃度在10~13ppm間之去除氨氮能力為26~43(mg/kg)，氨氮去除率為30~49(%)；而水力停留時間在2.5小時，其去除氨氮能力59~67(mg/kg)，氨氮去除率為32~70%。
根據本研究實驗結果，在污水處理系統，其污水氨氮濃度5~15ppm下，碳系濾材37 kg/m3以甘蔗渣與椰子殼1:1比例設置，於第6個月需添加原設置重量75%之椰子殼，第12個月添加原設置重量50%之椰子殼，之後每12個月添加原重75%之椰子殼。該模式可使污水再利用處理系統在設置碳系濾材之槽，於養菌一個月後一直維持在氨氮去除率70%以上之效果。

Ammonia removal is an important issue for the treatment of dosmetic wastewater. In this study,use the renewable water treatment tank of Liangshan Buildingin in Chung Yuan Christian University and four precision tubes for experiment,with bagasses and coconut shells for the biological treatment to remove ammonia in the wastewater. As well as,we used the ammonia removal rate、residual rate and the density setting in the treatment tank of these two materials as the design basis. To design a demand for filter weight and the filters add period similar the renewable water treatment in this study.
According to the result of previous study to experiment for filter depletion rate and ammonia removal rate. The result of treatment tank, the density of the coconut shells in the two tanks are 47.4(kg/m3) and 37(kg/m3) The first month,we found the removal capacity are 280.9(mg/kg) and 350.0(mg/kg). The twelfth month,the removal rate are 74.2(%) and 76.5(%).The result of precision tubes,after one month,the hydraulic residence time is 1 hour,we found the removal capacity are 26~43(mg/kg),and the removal rate are 30~49(%) . Then, the hydraulic residence time is 2.5 hour,the ammonia concentration of sewage is between 10~13 ppm,we found the removal capacity are 59~67(mg/kg),and the removal rate are 32~70(%) .
According to the result of the experiment,when the ammonia concentration of sewage is between 5~15ppm in the sewage treatment system. Setting the carbon biofilters is 37(kg/m3) by the ratio of bagasses and coconut shells is 1:1. In sixth month,add the coconut shells of 75% of original total weight. In twelfth month,add the coconrt shells of original total weight. Afterward,add the coconut shells of 75% of original total weight every twelve months once. This mode which setting carbon biofilters tank in water treatment system that can always maintained above 70% for ammonia removal rate after start one month.
