[FONT=新細明體][FONT=新細明體]原理如同最近流行的BioPellet,生化NP豆。但比NP豆要經濟實惠得多。誰敢一試?[/FONT][/FONT][FONT=新細明體]



[FONT=新細明體]In this research, rice husk, a lignocellulosic waste from agroindustry, was investigated as the sole carbon source as well as biofilm carrier in the biological denitrification of wastewater in up-flow laboratory reactors.An artificial wastewater with a temperature in the range of 27–33 ?C was used. Fast startup of the reactor and a high nitrate removal efficiency was observed. The highest rates of denitrification about 0.096 kg/m3 d were achieved when flow rate and nitrate concentration were 41.4 L/d and 25.0 mg/L, respectively.[/FONT]

[FONT=新細明體]Nitrite accumulation in treated water was practically zero during the experiments. Flow rate and nitrate concentration of the influent were observed to have a significant effect on nitrate removal efficiency. A very sharp decline was observed when the flow rate reached 30 L/d. The reactor had the ability to accommodate a wind range of pH(6.5–8.5) and DO(1.5–4). A time-dependent decrease in nitrate removal ratewas observed after 72 days of operation. And the addition of new rice husk brought about a rapid increase of the nitrate removal efficiency. The results showed that rice husk could be an economical and effective carbon source for the nitrate removal process.[/FONT]​

[FONT=新細明體]最終能達到0,水流對硝化起決定性作用,在水流約30L/d?(不懂這個單位)時,作用非常明顯,約72小時左右能起明顯效果。[/FONT]

稻殼............
一定要拿到無農藥的XD

不然會很慘
 
30L/d= 30 L/天
 
這是在農業上處裡堆肥(禽,畜糞便)的方式
搜尋堆肥應該很多資料吧

不過在水族上好像沒有這樣用法
 
稻穀!!!!????在都市哪裡有稻穀可以拿呢???
 
網拍上有賣, 不過一次要買一大包. :p
 
不知哪看到的
大陸的東西都黑心貨
也都很毒
不過毒藥是唯一黑心貨裡沒毒的
所以請安心使用(誤)

插個話,小弟看過一則笑話

大概是這樣的
有個人買啥東西都買到黑心的
到最後自己得了一身病,久病厭世,於是他就想買農藥自殺
結果他買了農藥喝下去後,難過得要死就是死不了
"x的,連農藥也是黑心的...."
 
比較好奇的是
要稻殼
來吸附
還是要上面的菌種來分解
