Mitsubishi MBR membrane treatment technology features
The effluent water quality is high quality and stable, and the effluent has no bacteria and solid suspended matter; the sludge concentration is high, generally 15~25g/L, the sludge load (F/M) is low, and the remaining sludge output is low; the reverberator is highly integrated and covers the land. Small area, not subject to setting occasions; easy to operate, easy to complete automatic control; high organic pollutant removal rate; strong biological nitrogen removal capacity; efficient integration of reverberator, small footprint; optional external cross-flow tube type Filter membrane; ultrafiltration, nanofiltration, reverse osmosis using integrated modular technology; aeration using specially planned jet aeration equipment; system automation is high; long-distance technical service can be completed.
Mitsubishi MBR Membrane External Membrane Biochemical Resonator (MBR) Technology
The external membrane biochemical reverberator (MBR) process is a typical wastewater treatment process that combines membrane technology with biotechnology. Using traditional nitrification, denitrification activated sludge biotechnology and advanced membrane separation technology, the ultra-microfiltration membrane module is selected as the mud-water separation unit, completely replacing the traditional secondary sedimentation tank, hydraulic retention time (HRT) and sludge retention. The time (SRT) is separated from the control, so that the sludge concentration in the bioreactor rises from 3 to 5 g/L to 15 to 25 g/L, and then the volume load of the reverberator is improved, so that the volume of the reverberator is reduced, so that the sludge mud The age has been greatly extended. On the one hand, the membrane retains the microorganisms in the reaction tank, so that the concentration of activated sludge in the pool is greatly increased, so that the biochemical reaction is more rapid and complete; on the other hand, the effluent is clear and the secondary sedimentation tank is saved. It has the advantages of high biochemical efficiency, strong impact resistance, stable water quality, small floor space, long mud discharge period and easy automatic control. It is especially suitable for waste leachate treatment.
Mitsubishi MBR Membrane Bioreactor Derivation Technology Membrane Biochemical Reverberation Derivative Technology refers to the membrane biochemical reverberator adding nanofiltration (or reverse osmosis) and supporting concentrated physicochemical treatment technology after effluent, due to the effluent ammonia nitrogen of membrane biochemical reverberator Targets such as total metal ions and SS have now reached emission standards, but some organic pollutants that are difficult to biodegrade or biodegradable cannot be removed. In order to reach higher emission specifications, nanofiltration (or reverse osmosis) should be used to further degrade the large molecular organic matter, and carry out advanced treatment to ensure that the effluent COD reaches the emission requirement. After the concentrated liquid is processed through the matching physical and chemical treatment, Complete the on-site disposal. Through the combination of the membrane bioreactor and its derivative technology specially planned and operated by our company, it can satisfy the requirements of various strict emission regulations and make the dope useful for treatment, especially suitable for waste leachate and high concentration organic wastewater. High specification and qualified processing.
The two-stage microbial denitrification membrane bioreactor technology was introduced in accordance with the new norm "Day Waste Landfill Pollution Control Specification" (GB16889-2008). In 2007, Wellley Company started the development and planning of two-stage biological nitrogen removal. In the original membrane biochemical reactor, denitrification and nitrification are added to the post-stage (secondary) denitrification and secondary nitrification process sections. When the first-stage denitrification and the first-stage nitrification and denitrification are incomplete, the deep denitrification reaction is carried out in the secondary denitrification and the secondary nitrification reverberator, and the two-stage biological nitrogen removal technology can reduce the biological nitrogen removal rate from the original single-stage organism. The 50-80% reduction in nitrogen removal has progressed to above 98-99%, reaching the regulatory requirements for total nitrogen emissions in the new regulations. Through the two-stage microbial denitrification membrane bioreactor specially planned and operated by our company, it can complete the stable and complete microbial denitrification reaction, especially suitable for the waste leachate treatment process with satisfactory new effluent.
