water treatment equipment of Membrane Bio-Reactor
I. Overview
MBR is a kind of high efficiency membrane separation technology and traditional activated sludge which combines the new and efficient wastewater treatment process , it has a unique structure with a submerged membrane module placed in the aeration tank , through aerobic aeration and biological treatment of water , filtered through a membrane by the pump out . It is the traditional method of sewage disposal has great difference , replacing the traditional biochemical processes secondary sedimentation tank and tertiary treatment processes.
Since the 1990s, membrane bioreactor has entered the stage of practical application . Membrane bioreactor has been used in the following areas:
Construction of urban sewage treatment and water reuse
Industrial Wastewater Treatment
Micro-polluted drinking water purification
Fecal sewage treatment
Land landfill / manure leachate treatment
2, Principle
Membrane bioreactor ( referred MBR) is a membrane separation technology and biological treatment technology directly engages the formation of a new water treatment technology that uses membrane selective permeability , make almost all of the microorganisms trapped in the bioreactor inside , which makes the membrane bioreactor high concentrations within the biological theory, SRT can be extended indefinitely , very effectively remove ammonia and organic molecules , organic content of the effluent to a minimum , the water is clear and transparent , without suspended solids , can be directly mixed with water as a life reuse . According to the different forms of arrangement , generally divided into sub -mounted and submerged MBR MBR ( also known as integrated ).
3, Overall structure and composition
Membrane bioreactor generally cell body, membrane , aeration systems, water systems and electric control system , etc..
1, the cell body
Cell body generally consists of welded steel plates and steel , on which there is the inlet and outlet pipes and drain pipes.
2 , membrane
MBR membrane module is the core component , mainly by the hollow fiber membrane and ABS pipes , composed by professional manufacturers, different sewage, membrane module parameter is not the same , mainly from the ultrafiltration membrane , the micro-organisms in sewage , large and suspended solids and other organic molecules trapped inside the MBR , the sewage purification.
3, the aeration system
Aeration system consists of the blower ( and its annexes ) , aeration piping and other components , the pipeline has a regulating valve membrane aeration intensity can be adjusted to reduce membrane fouling .
4 , the water system
Mainly composed of pumps, valves, piping , flow meters and other components, the pump flow and suction pressure and membrane match , the flow through the meter can be displayed directly .
5, the electronic control system
Electrical control system consists of PLC and electrical components and other components, its main function is to control the MBR automatically run and fault alarm, display and so on.
4 , MBR reactor Benefits
Since the presence of membrane solid-liquid separation greatly improves the system 's ability to make the system water quality and volume load have been greatly improved, the combination of different techniques, landscape water or effluent can reach miscellaneous water standards.
Since the membrane filtration , is completely trapped microorganisms in the bioreactor , the realization of the active HRT complete separation of sludge age , eliminating the conventional activated sludge bulking sludge .
Membrane bioreactor with high removal efficiency of pollutants , nitrification ability, can be performed simultaneously nitrification , denitrification effect, water quality and stability , sludge production is low , the device is compact, and easy operation .
Now widely used in a variety of biodegradability of domestic sewage and industrial wastewater treatment and reuse .
