The process of processing：A, first system inlet pipeline is bypassed；B, the sewage in pretreatment section container is emptied, vacating space loads
Activated sludge；C, the ponds MBR stopper film is discharged and is aerated, the carry pollutant being effectively peeled off in film wire；D, membrane cisterna liquid is imported
Pretreatment section containers store activated sludge.
The online medicament cleaning method suitable for sewage disposal MBR films, its main feature is that：Three component medicaments clean
When, the sodium hydroxide and sodium hypochlorite of mass percent concentration 0.5-2% is added, 2-12h is impregnated in alkali cleaning；Citric acid quality hundred
It is 0.5-2% to divide specific concentration.
The online medicament cleaning method suitable for sewage disposal MBR films, its main feature is that：When system is restored, the ponds MBR
It is added into food-grade glucose nutritive salt in COD 700-1500mg/L ratios；System aeration operation is lived for 20-30 hours
Property culturing sludge, maintain COD concentration, add food-grade glucose nutritive salt, continuous 2-4 days；System restores processing load point
Three phases increase treating capacity 25-35%, 50-70%, 90-
The invention has the advantages and positive effects that：
Online medicament cleaning method suitable for sewage disposal MBR films as a result of the completely new technical solution of the present invention,
Compared with prior art, effective solution of the present invention MBR film winter clean and maintenances antifreeze anti-drying problem ensures at sewage
Device MBR film winter maintenances maintenance is managed, has preferable operability, feasibility, reliability implements more convenient fast
It is prompt.
Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and it is described in detail
It is as follows：
Embodiment 1
A kind of online medicament cleaning method suitable for sewage disposal MBR films, including：Sewage-treatment plant pretreatment, three
The cleaning of component medicament, system restore technical process：
1, the pretreatment of sewage-treatment plant
The key of sewage-treatment plant MBR Membrane cleaning preconditioning techniques is that the activated sludge as much as possible in system is protected
It leaves and, so that sewage disposal system can restore normal operation as early as possible after MBR Membrane cleanings.
Specific steps：A first bypasses system inlet pipeline；By the sewage emptying in pretreatment section container, (vacating space fills b
Carry activated sludge)；The ponds MBR stopper film is discharged and is aerated certain time (being effectively peeled off the carry pollutant in film wire) by c；D will
Membrane cisterna liquid imports pretreatment section container (storage activated sludge).
2, three component medicaments clean
After the completion of pretreatment, the ponds MBR introduce clear water, carry out three component medicament cleanings.
Specific steps：A, after clear water did not had membrane module, stop water inlet；B, 1% sodium hydroxide and secondary chlorine are proportionally added into
Certain time (2-12h) is impregnated in sour sodium, alkali cleaning；C, washing lotion empties, and replaces clear water；It is proportionally added into 1% citric acid and carries out pickling
Impregnate certain time；D, washing lotion emptying, replacement clear water, washing empty after impregnating.
3, system is restored
After the cleaning of MBR film medicaments, system recovery technique is the key technology for ensureing Membrane cleaning effect.
Specific steps：A, activated sludge that 1 preconditioning technique of right is stored in pretreatment section leads back to the ponds MBR；b、MBR
Pond is added in COD 1000mg/L ratios into nutritive salt (food-grade glucose)；C, 24 hours (activated sludge of system aeration operation
Culture)；D, according to Inspection and analysis COD situations, COD concentration 1000mg/L are maintained, add nutritive salt, continuous three days.E, system is closed
It closes into water bypass line, starts to intake, processing load divides three phases to increase treating capacity 30%, 60%, 100%.
The present embodiment specific implementation process：
Time in midwinter at a time when real platform maintenance, inconvenience carry out offline MBR Membrane cleanings work, are carried out by the method for the present invention
The online medicament cleaning of MBR films.
Deposit activated sludge is had bad luck by preconditioning technique, three component medicament cleaning techniques wash film, system recovery technique weight
After opening sewage disposal system, compare cleaning performance such as following table：
It carries out as can be seen from the above table, the invention MBR film on-line cleaning technologies are identical as usual offline cleaning performance, MBR
Membrane flux restores fine.The present embodiment combination sewage-treatment plant online processing technology and offline medicament cleaning technique, effectively
Solve the problems, such as that MBR film winter clean and maintenances are antifreeze anti-drying, ensure sewage-treatment plant MBR film winter maintenances maintenance, tool
Standby preferable operability, feasibility, reliability implement more convenient.
