中文摘要 | 本研究利用農業廢棄物油菜籽粕作為基質,由本實驗室所購得的3株菌種所篩出的Bacillus subtilis(A)作為水解菌種,以所馴養的醱酵產氫菌做為產氫菌,進行一連串的水解串連醱酵產氫的兩段式反應槽連續試驗,以評估油菜籽粕之厭氧產氫之可行性。 本研究的試驗結果顯示,在相同總循序時間+水力停留時間下(12+24hr),以分離二段式反應槽SBR串聯CSTR,有最佳的單位體積反應槽每天產氫率(23.7 mmole-H2 /L.day),優於ASBR串聯CSTR,再優於共培養ASBR反應槽。不同起始pH分離培養反應槽SBR串聯CSTR,前段SBR的起始pH 值為7.0 時(出流水pH 6.82),有最佳的水解效果,溶解性COD增加率為17.8%;後段的CSTR醱酵產氫反應槽,當進流水pH =5.81(出流水接近於5.0-5.5)時,有最佳的單位體積反應槽每天產氫率為12.1 mmole-H2 /L.day。 本研究以水解SBR 反應槽串聯醱酵產氫CSTR 反應槽,其產氫量比單段反應槽之醱酵產氫率較佳,可得知油菜籽粕基質經由SBR水解後,可以有效提升產氫率,且油菜籽粕取得容易,所以利用油菜籽粕基質來產氫的可行性高。 |
英文摘要 | Rape-seed dregs, which are generating significant agricultural waste yearly, were used as a substrate in our study. Bacillus subtili(A)screened as out hydrolytic bacteria bought from BCRC, together with the fermentative hydrogenic bacteria cultivated in our laboratory as hydrogenic bacteria, was used in a series and in continuous input tests of two-stages reactors for hydrolysis and fermentative hydrogenesis to evaluate the feasibility of fermentative hydrogenesis of rape-seed dregs. The results show that with the same progressive times(12+24h), the optimal daily hydrogen (23.7 mmole-H2 /L.day)produced by the separated reactor SBR+CSTR was greater than that produced by ASBR+CSTR, and greater than the co-culturing ASBR reactor. For the separated reactor SBR+CSTR with different initial pH, the most optimal hydrolysis was obtained and the increase rate of soluble COD was approximately 17.8% when the initial pH of the preceding SBR was 7.0 (effluent with pH 6.82). For the posterior fermentative hydrogen producing CSTR, the optimal daily hydrogen attained 12.1 mmole-H2 /L when the influent pH was 5.81(influent pH approximately 5.0-5.5). The hydrogen production of the two-stage reactors was significantly higher than that of the single stage reactor. The rape-seed dregs substrate hydrolysis can be effectively enhanced by the SBR to promote hydrogen production. Rape-seed dregs are available everywhere. Therefore, it is feasible for rape-seed dregs to produce hydrogen. |
