The degradation rate of perchlorate in each reactor, sulfur granules are analyzed respectively by water quality monitoring mouth and mud sample tap
Flora distribution in utilization rate, reactor, detects the yield of hydrogen sulfide, result above is respectively referring to Fig. 3 ~ 7 by gas outlet 6.
From figure 3, it can be seen that as water inlet ClO4 -When load is relatively low, as 0.2 ~ 0.5g/ of embodiment 1 ~ 3（L·d）, Room 2 and
After 3 Room reactors run 1 day, 100% is reached to the degradation rate of perchlorate；Work as ClO4 -When load is higher, such as >=1.0g/（L·
d）When, after 3 Room reactors run 1 ~ 2 day, 100% is basically reached to the degradation rate of perchlorate；Especially work as ClO4 -Load is
1.5g/（L·d）When, after 3 Room reactors operations 5 days, 100% is reached to the degradation rate of perchlorate, and single chamber reactor is running
After 6 days, 80% about is only to the degradation rate of perchlorate.
From fig. 4, it can be seen that improving water inlet ClO4 -Load, can increase the utilization rate of sulfur granules.But for single chamber reaction
For device, work as ClO4 -Load is 1.5g/（L·d）When, even if the utilization rate of sulfur granules reaches 100%, its degradation rate also only has 80%
Left and right.
To the analysis of the flora of each reactor, referring to Fig. 5 it can be seen that：The top dominant bacteria of single chamber isSulfurovumWithHydrogenophilaceaeProportion is respectively 32.19% and 22.24%, and reactor lower part dominant bacteria isSulfurovumProportion is 57.79%；Dominant bacteria for Room 2 and 3 Room reactor upper and lowers isSulfurovum, ratio is all on 50%.
For single chamber, when forming biofilm, the dominant microflora of reactor lower part microorganism and the dominant microflora on top
Account for ratio and Species differences very big, reactor top easily produces side reaction.The Bacterial community of dual chamber and three Room is more single,
Because three Room and dual chamber have single water inlet, shorter than the time of single chamber and Bacterial community is more single on the biofilm time
One, unnecessary side reaction will not occur.For this reason, have studied amount and the water outlet that single chamber, Room 2 and 3 Room reactor head produce hydrogen sulfide
The amount of sulfate.The result of hydrogen sulfide referring to Fig. 6, with water inlet ClO4 -The increase of load, the sulfur of single chamber, Room 2 and 3 Room reactors
The yield changing hydrogen has all reduced, as water inlet ClO4 -Load increases to 1.5g/（L·d）When, 3 Room reactors go to perchlorate
When reaching 100% except efficiency, hydrogen sulfide yield is zero；And single chamber reactor to perchlorate removal efficiency be only 80% about, and
The amount producing hydrogen sulfide is in 10mg/L.The result of water outlet sulfate referring to Fig. 7, with water inlet ClO4 -The increase of concentration, single chamber,
The yield of the sulfate of Room 2 and 3 Room reactors all increased, and with the minimizing of hydraulic detention time, single chamber, Room 2 and Room 3 are anti-
The yield answering the sulfate of device has all reduced, but, Room 2 and 3 Room reactors are compared with the amount of the water outlet sulfate of single chamber reactor
Will be low.
In sum, this utility model improves the utilization rate of filler sulfur granules, thus decrease by-product hydrogen sulfide and
The generation of sulfate.The technical problem of traditional single chamber reactor is to make full use of the space of fixed bed reactors, degraded
The position of pollutant is mainly in middle and lower part, and the system on reactor top will change, and the side reactions such as sulfur disproportionation occur, from
And increased the generation of water outlet sulfate and hydrogen sulfide.This utility model is exactly to make full use of reaction using multiple hearth reactor purpose
The space of device, reduces the generation of side reaction.Result of the test shows, the utilization rate that dual chamber compares single chamber sulfur with three Room is respectively increased
15% ~ 30%, the yield of hydrogen sulfide reduces 50% ~ 100%, and the yield of sulfate decreases 15% ~ 30%, to higher water inlet ClO4 -Negative
