The test results of membrane SBR treatment of leather wastewater show that the SBBR method has a shorter operating cycle and a higher degradation rate than SBR, and reaches the same effluent standard.
The aeration time of SBBR is shorter than that of SBR, which saves energy
.
The effluent COD value of SBBR is significantly better than SBR
The production of mustard tuber produces high-salt and high-nitrogen wastewater.
After inoculating the salt-tolerant bacteria screened from the mustard pickling wastewater in the SBBR reactor, the reactor has good applicability to high-salt wastewater.
At the same time, microscopic inspection reveals organisms.
There are a large number of filamentous bacteria in the membrane
.
The reactor also has strong nitrification and denitrification capabilities, and factors such as organic load, nitrogen load, DO, and pH have significant effects on the denitrification efficiency of the reactor
The results of SBBR treatment of landfill leachate show that when the system influent CODcr and NH 3 -- N are respectively 810 mg/L and 93 mg/L, the system effluent CODcr and NH 3 -N are respectively 160 mg/L and 28 mg/L
.
The operating results show that the system can operate stably under this condition
Domestic scholars have designed the pre-MAPSBBR coupling process to treat the early and late landfill leachate in accordance with the characteristics that the water quality of landfill leachate is gradually deteriorating with the extension of the landfill time
.
The results show that, under the best operating conditions, its early leachate NH2 .
The SBBR is equipped with plastic Pall ring packing, which is used to treat actual domestic sewage under aerobic conditions.
The results show that the reactor can create an anoxic microenvironment very well.
The carrier biofilm has the ability to adsorb carbon and store carbon, and a good SND appears.
Phenomenon
.
A batch biofilm reactor was used to study the effect of organic carbon on the aerobic denitrification of actual domestic sewage with a low carbon to nitrogen ratio (COD/TN around 3).
The experimental results show that the average removal rate of total nitrogen is 80% under aerobic conditions
.
Foreign scholars using SBBR Process wastewater containing cyanide, in one operation cycle of 24h, 20mg / L cyanide may be degraded to 0.
5mg / L, while a 1: 1 stoichiometry converted to NH2 .
3 -N
.
This shows that the closed operation of SBBR is very suitable for the treatment of wastewater containing toxic and volatile pollutants such as mine leachate
SBBR also has broad development prospects in the removal of nitrogen and phosphorus.
The research on the mechanism of defluorination and phosphorus removal in SBBR reactors and the exploration of the mechanism of biofilm activity will also become one of the research hotspots of the majority of scholars; the pre-cultured strains Adding to the SBBR reactor not only improves its domestication efficiency, shortens the start-up time of the reactor, but also improves the treatment capacity and treatment effect of the reactor.
It will surely become one of the leading directions in the SBBR research field
.
The SBBR process has both the advantages of the SBR process and the advantages of biofilm.
It can be designed as aerobic or anaerobic reactors and other different operating modes
.
It has a very good effect in removing industrial wastewater and toxic and harmful organic matter.
SBBR sewage treatment technology is a new process suitable for domestic sewage and industrial wastewater
.
The process has strong impact load resistance, compact structure, small footprint, high treatment efficiency, stable effluent quality, no need for sludge backflow and backwashing, and simple maintenance and management
It can be seen that the moving bed biofilm reactor has great prospects for development and application.
Because of its simple construction and convenient operation, the existing conventional sewage treatment plant can be transformed without increasing the volume of the reactor to improve the removal of organic matter.
Rate and achieve the purpose of nitrogen and phosphorus removal
.
The popularization and application of this technology should be vigorously promoted in China
