以菱角炭拜香進行寺廟懸浮微粒濃度改善成效探討=Discussion on the Effect of Improving the Concentration of Suspended Particulate in Temples with Carbonized Water Caltrop Shell in Incense Production
This study is mainly for the addition of carbonized water caltrop shell biochar for the production of Value-added development and low pollution incense products. The water caltrop shell is the main biological agricultural waste in Taiwan. Due to its tight texture and the difficulty of decomposition of organisms, it is difficult to carry out composting. At present, it is almost to dispose of field or open burning. The Guantian District of Tainan City carbonized the water caltrop shell to form a biochar, and developed products such as handmade soap and air purifying bags. However, due to the low price, the promotion value is limited. The results show that the use of carbonized water caltrop shell biochar to add to the incense can reduce the fine particulate matter(pm2.5) in incense burning(from 67.5 to 30.9 mg / g-incense), and it can conform the low pollution incense standard value. This study also carried out a real-field test, in two shrines. Addition a carbonized water caltrop shell in incense production for the discussion on the effect of the incense burning smoke concentration. The analysis results show that the concentration of fine particulate matter is 53.3±3.5 and 50.4±7.4 μg/m3 when burning carbonized water caltrop shell biochar with incense, and the concentration of fine particulate matter is 84.2±20.7 and 75.4±28.3 μg/m3 when burning a generally incense. It can be seen that when the same amount of incense is burned in the same indoor space, the concentration of indoor suspended particles is low (about 2/3). In conclusion, the addition of carbonized water caltrop shell biochar can effectively reduce the fine particulate matter and achieve the low pollution standard value of the incense, and Carbonized agricultural waste to produce value-added development products. This study has positive implications for improving environmental sanitation and recycling of agricultural waste.
