Description
(1) technical field
The present invention relates to the method for a kind of granule sludge and Dynamic Membrane combined treatment waste water, can remove the multiple pollutants such as organism, nitrogen, be applicable to process trade effluent and municipal effluent.
(2) background technology
Bioreactor of dynamic membrane (Dynamic Membrane Bioreaetor, DMBR) is to utilize in the operational process sludge blanket that forms on the nethike embrane surface, thereby sludge retention is realized a kind of technique of purifying waste water in reactor.This technique has the advantage of membrane bioreactor (MBR), need not settling tank and the sludge reflux system of conventional biologic process for treating sewage, has significantly reduced the cost of membrane module simultaneously, and film pollutes easier being effectively controlled.Dynamic Membrane preparation is simple, and employed basement membrane is generally non-woven fabrics cheap and easy to get, and screen cloth etc. are when microorganism and meta-bolites thereof have just formed Dynamic Membrane during in basement membrane deposition film forming.Bioreactor of dynamic membrane has the advantages such as equipment is simple, easy and simple to handle, treatment effect better, expense is lower, and its shortcoming is that the membrane resistance lift velocity is fast, and filtration cycle is short, and membrane contaminant is difficult for being cleaned removal, and effluent quality is stable not.On structure, Dynamic Membrane can be divided into filter cake repeatly, gel coat and membrane matrix.Gel coat and membrane matrix in conjunction with more intense, preferably interception capacity is arranged; Cake layer mainly is comprised of the mud floc sedimentation, and is loosely organized, very weak with the bonding strength of bottom.The formation of Dynamic Membrane and performance thereof are subjected to the impact of several factors, such as aeration intensity, and the cross-flow flow velocity, water head-drop, sludge concentration and influent quality etc. are so the film formation time of Dynamic Membrane length also is one of its shortcoming.
In bioreactor of dynamic membrane, biological sludge plays a major role to pollutant removal.By being summed up, the application experience of domestic and international bioreactor of dynamic membrane finds that effluent quality is unstable to be the important factor that this technical development is obstructed.Effluent quality is unstable to comprise that mainly the variation of turbidity is larger, the situation of sludge loss occurs easily, and the loss of mud then can cause sludge concentration decline in the reactor, and handling property reduces.
Aerobic Granular Sludge Technology is to be the biotechnology that the mud granule of certain particle diameter and realizing is disposed of sewage by the flco culturing sludge in certain reactor and under the operational condition.This technical study mainly is to carry out in the sequencing batch activated sludge reactor of periodic running, sometimes need to add sludge carrier in culturing process.Have research to point out, in the reactor of periodic running, short hydraulic detention time and larger current shearing action help to form aerobic particle mud, and sedimentation time is the principal element that affects the aerobic grain bacterium colony.
Aerobic granular sludge reactor can adopt different vaccination mud, comprises cotton-shaped active sludge and anaerobic grain sludge.The method that directly adopts anaerobic grain sludge to tame is easy and success ratio is high; And take common cotton-shaped active sludge as seed sludge, start time is long, and the control difficulty is larger.There is the investigator in the sbr reactor device, to turn out aerobic particle mud take anaerobic grain sludge as seed sludge, and do not succeed take ordinary activated sludge as seed sludge.Obviously, aerobic particle mud exists cultivates difficulty, the slow defective of toggle speed, and generally is applied in the batch process.
In order to solve granule sludge and Dynamic Membrane defective separately, and realize having complementary advantages, this project is planned Dynamic membrane and is introduced in the granule sludge treatment technology, forms a kind of novel Dynamic Membrane and the COMBINED PROCESS of granule sludge.
Dynamic membrane and granule sludge combination technique utilize Dynamic Membrane to the crown_interception of particulate matter, can effectively guarantee the biomass in the reactor, and realize continuously operation; Utilize the large grain diameter of granule sludge more can effectively be trapped within the Dynamic Membrane reactor, avoid sludge loss, realize steady running.In addition, because granule sludge has larger particle diameter, penetrating of oxygen had suitable resistancing action, even there is certain oxygen concn the particle outside, the inner microenvironment that still can form anoxic, granule sludge can be created different environment, makes nitrobacteria and denitrifying bacterium possess the space that is fit to separately, can play a role simultaneously, be conducive to Simultaneous Nitrification and denitrifying carrying out.Thereby, granule sludge-Dynamic Membrane combination process in removing waste water organism and nitrated anti-nitre denitrogenation aspect have huge potentiality.
