| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 95 === In this study, the performancr of Aerobic Sequencing Batch Reactor (ASBR),Anaerobic Sequencing Batch Reactor (ANSBR),Aerobic Membrane Bioreactor (AMBR), AMBR/RO, Anerobic-Oxic Membrane Bioreactor (AOMBR), AOMBR/RO processes treating pharmacy waste water that includes high fibre in different HRT was investigated and compared for effluent water quality and retrieve and utilize feasibility.This research utilized PTFE membrane and commercial K membrane the membrane centre of Central Plains to research and develop to treat waste water in MBR.
In ASBR procedure, when HRT was over 12 hours, the removal efficiency of TCOD and BOD can be more than 76% and 87%. In 8 hours, the removal efficiency of TCOD and BOD become 65% and 82%. When operate under the shortest 4 hours, the removal efficiency of TCOD and BOD is 38% and 43% only left. If using ASBR procedure to treate the high fibre waste water want to have treate efficiency, it must control HRT in above 12 hours.
In AMBR procedure, even control HRT under 4 hours, the removal efficiency of TCOD and BOD stills have 94% and 98%. It show that can remove TCOD and BOD in this water without foaming in this procedure. If want to accord with effluent standard (COD<100 mg/L, BOD<30 mg/L), it should control HRT in above 12 hours. In this procedure, Central Plains membrane and a commercial K membrane to compare the removal efficiency of TCOD and BOD are similar. So in this research, the two membrane can have good removal efficiency.In AMBR/RO procedure, control HRT under 8 hours, the removal efficiency of TCOD and BOD stills have 94% and 100%.
In AOMBR procedure, HRT more than of 12 hours, the removal efficiency of TCOD and BOD are 97% and 98% respectively. It is similar to AMBR procedure. But HRT in 8 hour, the removal efficiency of TCOD and BOD become 84% and 96%. In 4 hour, it becomes 61% and 88%. It show that anerobic tank can not operate under short time. Among AOMBR/RO procedure, control HRT under 8 hours, the removal efficiency of TCOD and BOD stills have 91% and 98%.
At AMBR and AOMBR procedure, all effluent are yellow and have less combined chlorines and E-coli. It can be through add NaClO and NH to make it accord with the standard. But among AMBR procedure, TDS concentration is still too high. And in AOMBR procedure, total Soda degree concentration is still too.
In AMBR/RO and AOMBR/RO procedure, the effluent water will turn into transparent and colourless. E-coli is all removal. TDS and soda degree also have good removal efficiency. Because RO can deal with effectively water salinly, heavy metal and chemistry remain materials more than 95%. And it has good removal efficiency for color. So in two procedures, it only have to add NaClO and NH in influent lead to effluent accords with combine chlorine standard.
