Description

Intermittent filtration program controller of membrane bioreactor module
Technical field
The invention belongs to Membrane Bioreactor for Wastewater Treatment waste water control techniques, be specifically related to a kind of intermittent filtration program controller of membrane bioreactor module.
Background technology
Membrane bioreactor is one of waste water reclaiming regenerative use technology of the tool potentiality that grow up of twentieth century end, and membrane bioreactor is a kind of water treatment system that membrane separation technique is combined with bioreaction technology.It has advantages such as the space of occupation of land is little, solid-liquid separation rate height, activated sludge concentration height, processing efficiency height, effluent quality is good, sludge yield is low, operational management is simple.
Membrane biological reaction assembly operating mode is intermittent operation, generally controls by motorized valve or magnetic valve.Several membrane biological reaction component groups become the membrane biological reaction module, by several membrane biological reaction module component film bio-reactors.Therefore a membrane bioreactor has many motorized valves or magnetic valve, breaks down as a motorized valve or magnetic valve, can cause the membrane bioreactor module out of service.Because motorized valve or magnetic valve quantity are many, cause the failure rate height.
Summary of the invention
The present invention overcomes above technical deficiency, has proposed a kind of intermittent filtration program controller of membrane bioreactor module.Sequence controller of the present invention is made up of water inlet dish, water tray, rolling disc.The water inlet dish is provided with several water inlet interfaces, and each water inlet interface connects a membrane biological reaction module.Water tray is provided with a water outlet interface, and annular cavity and the filtration channel of rolling disc of the water outlet interface of water tray by water tray coils certain several water inlet interface with its water inlet and dynamically link to each other.Water outlet interface junctional membrane bio-reactor suction system.Rolling disc is provided with filtration channel and suspends stifled.Rolling disc turns round under motor drives, always has one tunnel water inlet obstructed in the running, and several roads all communicate in addition, thereby cycle alternation reaches controlling diaphragm biological respinse module intermittent operation purpose.
If membrane bioreactor has L membrane biological reaction module (water inlet of L road), be m (m is an integer) as the suction of membrane biological reaction module with the time scale of stopping inhaling, stopping the suction time is d minute.Technical solution then of the present invention is: a kind of intermittent filtration program controller of membrane bioreactor module is characterized in that: combined by water inlet dish, water tray and rolling disc; Water tray is sleeved on the rotation axis of rolling disc, and and rolling disc be installed in together in the inner chamber of water dish into.L water inlet interface is installed on the described water inlet dish, and the central angle of nearest two water inlet interface correspondences is Other adjacent two pairing central angles of water inlet interface are
Figure GSB00000362351900021
Have L arc filtration channel on the rolling disc, stifled for suspending between the passage, total L is suspended stifled; Arc filtration channel and the stifled arc length ratio of time-out are m; A water outlet interface is installed on the water tray, and and water tray on annular cavity communicate.For solving operating sealing problem, between rolling disc and water inlet dish, and between rolling disc and the water tray sealing-ring is installed.
Rolling disc is by motor drives, and making one week of turn disc is L (m+1) d minute.Wherein L, m, d are positive integer, and the value of central angle must be greater than zero, otherwise do not have the physics meaning.
Have only one the tunnel obstructedly in operation process, several roads all are in logical state in addition, the cycle alternation water outlet, and one road flooding velocity is Q, total water flow is Q (L-1).
Water inlet interface and water outlet interface cross section and rolling disc arc filtration channel width are determined according to working flow.One road flooding velocity Q, its water inlet interface overflow section 〉=Q (m 3/ s) ÷ 0.6m/s; Water outlet interface overflow section 〉=[Q (m 3/ s) ÷ 0.6m/s] * (L-1); Rolling disc arc filtration channel width equals into the water interface and crosses flow diameter.
The present invention is simple in structure, and an electric mechanical equipment can replace several motorized valves or magnetic valve, reduces the operating failure rate of membrane bioreactor, has improved the membrane bioreactor reliability of operation.
