摘要

浮式处理湿地(FTW)是利用植物根系作为污染物吸收剂,去除氮(N元素)、磷(磷/P元素)等废弃物的一种湿地形式。本研究的目的是考察利用超滤法对合成磷废渣进行除磷的反应速率。所使用的水生植物为茉莉(Echinodorus palifolius)和香蕉(Helliconia psittaforum)。四个FTW池装满了合成磷废物。第一个池塘为对照池,第二个池塘为不含植物的FTW,第三和第四个池塘分别为上述水生植物。该研究于2019年7月至8月中旬进行。在四个水池中取水样,第一周取5次,第二周取3次,第三至第六周取2次。测定的参数有水温、pH、氧化还原电位(ORP)和磷酸盐。所进行的数据分析是计算每个测量样品的磷酸盐反应速率。磷酸盐的速率随着试验池中磷酸盐浓度的降低而成比例地降低。水生植物已被证明可以从合成废物中去除磷酸盐,将其作为植物生长的营养物质。

Laju Reaksi Penghilangan Fosfat pada Limbah Cair Artifisial NPK Menggunakan Sistem Floating Treatment Wetlands
Floating Treatment Wetland (FTW) is a form of wetland that functions to remove waste such as Nitrogen (N element) and Phosphorus (Phosphorous/P element) waste by utilizing plant roots as pollutant absorbers. This study aims to examine the reaction rate of phosphate removal from synthetic P waste through FTW. The water plants used were water jasmine (Echinodorus palifolius) and banana (Helliconia psittaforum). Four FTW ponds are filled with synthetic P waste. The first pond is a control pond, while the second pond is filled with FTW without plants, and the third and fourth ponds are filled with each of the aquatic plants mentioned above. The study was conducted from July to mid-August 2019. Water samples were taken in four pools five times in the first week, three times in the second week and twice in the third to sixth weeks. The parameters measured are water temperature, pH, Oxidative Reductive Potential (ORP) and phosphate. The data analysis carried out was calculating the phosphate reaction rate for each measured sample. The rate of phosphate decreases in proportion to the decrease in phosphate concentration in the test pond. Aquatic plants have been proven to remove phosphate from synthetic waste by using it as a nutrient for plant growth.
