As the core component of the immersed membrane bioreactor, the film has the reliable stability of the membrane bioreactor. As an innovative flat membrane product, the double — fold flat membrane has greatly improved the energy efficiency of the system and reduced the energy consumption.
Function configuration of Membrane bioreactor:
I. the principle and form of flat film
Screening process, membrane bioreactor (MBR) operating pressure 0 to 35 kpa, mixture under the action of static pressure difference or self-priming pump, through the cellulose or polymer microporous membrane filter material, USES the uniform pore size, to intercept the water particles, bacteria, etc., make it can’t be removed by a membrane.
Product features editor
The mud water was filtered by membrane and the mud water was separated. On the one hand, the membrane intercepts the microorganisms in the reaction pond, so that the concentration of activated sludge in the pool increases, so that the biochemical reaction of the degraded wastewater is more rapidly and thoroughly. On the other hand, due to the high filtration precision of the membrane, the water is clear and transparent, and the water is produced with high quality.
The membrane pool sets up the MBR membrane module system and the supporting water outlet, cleaning, purge and other systems. The purge (aeration) in the MBR membrane is used for two purposes. One is for the air and water oscillation around the membrane components to keep the membrane surface clean, and the other is to provide the oxygen needed for biodegradation. Through the efficient interception of membrane, all bacteria and suspended objects are trapped in aeration pool, which can effectively intercept nitrifying bacteria and make the nitrification reaction proceed smoothly and effectively remove ammonia nitrogen. At the same time, it can intercept the large molecular organic matter which is difficult to degrade, and prolong the time in the reactor to get the maximum degradation. Residual sludge is discharged regularly through residual sludge pump in the membrane area, and the concentration of activated sludge and the sludge age can be controlled.
1.1 MBR membrane bioreactor abroad development status
MBR membrane technology was originally used in the biological fermentation industry, and in 1965, Blat et al., etc., was used in the process of continuous fermentation of enzymes to enrich the microorganism.
In the early ’60s, it began to be used for wastewater treatment. In 1967, the company dorr-oliver built a 3600gpd small sewage treatment facility.
Smith1969 first reported using ultrafiltration membrane to replace the sink in activated sludge process.
At that time, limited by membrane manufacturing technology, the water quality requirements were not high, mainly staying in the laboratory scale.
In the 1970s and 1980s, Japan began to study hard. From 1983 to 1987, 13 companies used MBR membrane bioreactors to treat waste water from buildings.
Canadian ZENON commercial products — ZenoGem was put into use in 1982;
Meanwhile, the study of anaerobic bioreactor and membrane technology was taken seriously in the early 1980s.
Since the late 1980s, research has been in the ascendant.
A submerged MBR launched in 1989, the MBR membrane bioreactor operating conditions optimization, membrane fouling mechanism research thorough, the diversification of objects and dealing with waste water, sewage, feces wastewater, organic industrial wastewater, the application is more extensive, Britain, Germany, the Netherlands, the United States, Japan, France, South Africa and Australia and other countries has received many applications.
Eu MBR project put forward the following research contents: to speed up urban sewage purification technology development as the goal of membrane, reduce the cost of construction and operation of urban sewage treatment the MBR technology, process optimization and membrane pollution control, decentralized energy saving technology and processing the MBR.
1.2 domestic development of MBR membrane bioreactor
The study of MBR in China began in the early 1990s, and the 1996 national «ninety-five» attack began to fund MBR research.
In 2002, the national 863 project continued to fund MBR research, which was funded by tsinghua, zhejiang university and tianda.
The aim of the national 863 project is to comprehensively develop the research and application of MBR.
During this period, the relevant papers and research institutions increased substantially.
Shanghai institute of applied physics, Chinese academy of sciences in 80 began to ultrafiltration membrane technology research, after 20 years of ultrafiltration membrane technology research and development and the actual project work, in science and technology commission of Shanghai in 95, under the impetus of the successful completion of the ultrafiltration membrane techn
