Abstract
The utility model provides a take fragrant catalytic processing device of sewage of membrane module, includes that reactor and H2O2 throw and adds jar, H2O2 throw add jar with the reactor through throwing with the union coupling, throw to add to be provided with on the pipe and throw with the valve, the bottom of reactor is provided with the aeration pipe, reactor is provided with the membrane module, and the outside of reactor is provided with the circulating pipe between ligation ware bottom and the reactor upper portion, is connected with the circulating pump on the circulating pipe, and the circulating pipe is in the part on the reactor upper portion outside at the membrane module, be provided with the outlet pipe in the membrane module. The device combines together a sweet smell catalytic technology and membrane separation technique, has reduced the work burden of membrane module, helps slowed down membrane pollution, preventing film seal lock stopper, through dirty recycling of water mass transfer, the contact of pollutant with the fenton reagent has been strengthened to get rid of the large granule water that is difficult for catalytic degradation, improved the quality of water after filtering.
Description
Technical field
This utility model relates to a kind of device for sewage disposal, belongs to technical field of sewage.
Background technology
Fenton (Fenton) reagent method waste water advanced oxidization treatment technology, has the ability of higher removal persistent organic pollutants.Fenton reagent method catalytic oxidation process for treating principle is made by H2O2With the catalytic oxidation such as iron salt mechanism, produce the hydroxyl radical free radical (OH) with extremely strong oxidisability, the feature at high cloud density position in there is " attack " organic molecule by hydroxyl radical free radical, saboteur's chain structure, the Organic substance making major part difficult degradation is CO by the thorough mineralising of OH free radical rapidly2And H2O。
But Fenton reagent method dominant response mode is for carry out in an agitating reaction pond at present, for discontinuous reaction, there is problems in that the bad grasp of (1) reaction condition, the range of accommodation of pH value, the optimum dosage etc. of medicament need Artificial Control, easily causing error, work difficulty is big；(2) can not abundant mineralising Organic substance, parent material is partially converted into some intermediate product, these intermediate products or and Fe3+Form complex, or compete with the generation route of hydroxyl radical free radical OH, and may be bigger to the harm of environment；(3) cannot accurately control response parameter, cause added amount of chemical inaccuracy, such as H2O2Utilization rate the highest.
Utility model content
The deficiency that this utility model exists for existing Fenton (Fenton) reagent method wastewater processing technology, it is provided that a kind of H2O2Utilization rate height, high treating effect, can the sewage Fenton device for catalytic treatment of band membrane module of continuous running.
The sewage Fenton device for catalytic treatment of band membrane module of the present utility model, by the following technical solutions:
This device, including reactor and H2O2Add tank, H2O2Adding tank to be connected by adding pipe with reactor, add to be provided with on pipe and add valve, the bottom of reactor is provided with aeration tube；Being provided with membrane module in reactor, the outside of reactor is provided with the circulation pipe bottom coupled reaction device and between reactor top, and circulation pipe connects circulating pump, and circulation pipe is in the outside being partially in membrane module on reactor top；Membrane module is provided with outlet pipe.
Connect on described aeration tube and have gas flowmeter.
After sewage enters reactor, add H2O2, make the sewage of inside reactor be sufficiently mixed mass transfer, H by circulation pipe and circulating pump2O2Diffuse to whole inside reactor, H2O2With the Fe in sewage2+Constitute Fenton reagent, and constantly consume and degradation of contaminant.Pollutant are degraded, and water sample becomes clarification.Simultaneously as the membrane filtration effect of membrane module, sewage is constantly pumped to film surface, and is taken away the H of excess with current2O2, form more Fenton reagent.Reactor constantly obtains dissolved oxygen by aeration tube, continues aeration and ensure that the concentration of dissolved oxygen in system so that the Fenton catalytic degradation of whole device and membrane filtration processes continuous service, is efficiently treated through sewage.
Fenton catalysis technique and membrane separation technique are combined by this utility model, reduce the work load of membrane module, contribute to decelerating membrane pollution, prevent Pore Blocking；By the circulation mass transfer of sewage, strengthen pollutant and contact with the effective of Fenton reagent, and remove the bulky grain water being difficult to catalytic degradation, improve the water quality after filtration.

Detailed description of the invention
The sewage Fenton device for catalytic treatment of band membrane module of the present utility model, mainly includes reactor 1 and H2O2Add tank 7, H2O2Add tank 7 to be connected by adding pipe with reactor 1, add to be provided with on pipe and add valve 8.The bottom of reactor 1 is provided with aeration tube 2, and aeration tube 2 connects gas flowmeter 3.Membrane module 4 it is provided with in reactor 1.The outside of reactor 1 is provided with the circulation pipe 5 bottom coupled reaction device and between reactor top, and circulation pipe 5 connects circulating pump 6, and circulation pipe 5 is in the outside being partially in membrane module 4 on reactor top.Membrane module 4 is provided with outlet pipe 9.
Sewage enters reactor 1, opens and adds valve 8 and add in reactor 1 and pass through H2O2, make the sewage within reactor 1 be sufficiently mixed mass transfer, H by circulation pipe 5 and circulating pump 62O2Diffuse to whole reactor 1 internal, H2O2With the Fe in sewage2+Constitute Fenton reagent, and constantly consume and degradation of contaminant.Pollutant are degraded, and water sample becomes clarification.Simultaneously as the membrane filtration effect of membrane module 4, sewage is constantly pumped to film surface, and is taken away the H of excess with current2O2, form more Fenton reagent.Reactor 1 constantly obtains dissolved oxygen by aeration tube 2, continues aeration and ensure that the concentration of dissolved oxygen in system so that the Fenton catalytic degradation of whole device and membrane filtration processes continuous service, is efficiently treated through sewage.
