對於工廠及民生廢水的處理方法仍是使用生物脫氮的脫硝作用以及電化學處理的方法來進行,然而一般民生廢水和養殖業的廢水NH4-N最後都在100 ppm後而無法繼續處理。 本研究以稻殼炭為主體,並將錳氧化菌進行稻殼炭載菌之試驗,製備載菌稻殼生物炭,並以配置不同種類的氨水利用兩種菌種進行去除,並由各組實驗可以得知,以錳氧化菌Pseudomonas putida strain MnB1及純化後之錳氧化菌#16進行各類氨水之去除試驗,除了氫氧化氨外,其餘磷酸氨、醋酸氨、氯化銨、硫酸亞鐵氨皆有一定效果之去除,而製成之載菌稻殼生物炭針對100ppm以下之氨氮廢水降解,也均有70%-90%的去除效果。
For the factory and the municipal wastewater is still using denitrification biological nitrogen removal and a method for electrochemical processing. However, municipal waste water and farming wastewater effluent ammonium nitrogen eventually unable to continue processing lower than 100 ppm . In this study, pseudomonas putida strain MnB1 and #16 were used to dope rice husk biochar. Preparation of varions amount of bacterium doped rice husk biochars,for different types of ammonia removal by using MnB1 and #16. Results showed that, except ammonium-hydroxide,phosphoric acid, ammonium acetate, ammonium chloride, ammonium iron(II) sulfate were gained great overall efficiency. Bacterium doped rice husk biochar for ammonia wastewater which has less than 100ppm of degradation, also have 70% -90% removal efficiency.
