Description

Advanced oxidation bi-membrane method wastewater reusing device
Technical field
The utility model belongs to field of sewage treatment, and in particular to a kind of advanced oxidation bi-membrane method reusing sewage dress Put.
Background technology
With the continuous improvement of national environmental protection sewage drainage standard, the requirement to sewage-treatment plant is also higher and higher, passes The sewage-treatment plant of system cannot meet the requirement of sewage discharge, in traditional sewage-treatment plant, ozone-oxidizing device Be provided separately with ultrafiltration apparatus, construction cost is high, its reason in environment of traditional organic film in oxidation service life it is big Amplitude declines, even if being provided separately, remaining oxidisability also can cause strong influence to the service life of organic film in water, make The replacement frequency of film increases, and causes operating cost very high, although can be adjusted by dosing, operating cost is still very high.
Utility model content
The purpose of this utility model solve traditional wastewater processing unit there are it is of high cost the defects of, there is provided a kind of advanced oxygen Change bi-membrane method wastewater reusing device, it is by together with ozone-oxidizing device and earthenware slab film combination, service life length, water process Effect is good, and construction cost and operating cost are low.
The utility model is achieved by the following technical solution:
I.e. a kind of advanced oxidation bi-membrane method wastewater reusing device, it is characterised in that including ozone oxidation tank, earthenware slab film, Dosing tank, intermediate water tank and counter-infiltration system, ozone oxidation tank set water inlet and ozone air inlet pipe, ozone air inlet bottom of the tube to prolong Reach the bottom of ozone oxidation tank, inside installation earthenware slab film, earthenware slab film respectively by pipeline and ozone oxidation tank outside The backwashing pump in portion, Aeration fan, production water pump connection, backwashing pump, production water pump are connected by pipeline with intermediate water tank respectively, middle water Case is connected by pipeline with counter-infiltration system, and above-mentioned pipeline is equipped with high-pressure pump, is additionally provided with dosing tank outside ozone oxidation tank, adds Medicine-chest is connected by pipeline with dosing pump, and dosing pump is connected by the pipeline between pipeline and backwashing pump and ozone oxidation tank.
The earthenware slab film of the utility model makes current be filtered by film by producing water pump suction, is supervised by vacuum table Survey, when the negative pressure of suction reaches predeterminable level, illustrate film surface generate it is dirty block up, automatically begin to backwash process, use backwashing pump Backwash will be carried out to diaphragm after water pressurization in intermediate water tank, while be added to the cleaning liquid in dosing tank by dosing pump In backwash water, filter process is transferred to after backwash again.
For the ozone oxidation tank of the utility model by deepening water level height, the residence time increase of increase microbubble in water is smelly The dissolved efficiency of oxygen.
The earthenware slab film antioxygenic property of the utility model is strong, can be used for a long time in Strong oxdiative environment.
The earthenware slab film (Ceramic Plate Membrane) of the utility model is with Al2O3Passed through for main material Porous membrane prepared by 1300-1600 DEG C of high temperature, the product developed mainly for current organic film shortcoming, it possesses machinery Intensity is high, and chemical stability is good, and resistance to oxidation, antipollution, easy cleaning, long lifespan, even aperture distribution is indeformable, UF membrane efficiency Height, good hydrophilic property, the advantage such as energy saving, particularly suitable for the highly difficult waste water of the industry such as chemical industry, pharmacy, printing and dyeing, landfill leachate Processing.
The counter-infiltration system of the utility model uses counter-infiltration system known in the art.
The utility model is realized using the technique of ozone high grade oxidation+bi-membrane method (earthenware slab film+reverse osmosis membrane) combination The technology of reusing sewage.Ozone is a kind of excellent strong oxidizer, in wastewater disinfection, except color, deodorization, organics removal and COD Aspect has good effect.Ozone oxidation degradation of organic substances speed is fast, and mild condition, does not produce secondary pollution." bi-membrane method " water Treatment process, is the brand-new water treatment technology proposed around advanced film science and technology, can be returned most trade effluent With it organically combines different membrane process, and certain water standard is reached after rational advanced treating, returns With to boiler feed water system and circulating cooling make-up water, it is changed into " reusing sewage " by " sewage disposal " of traditional sense, is realized The reusing sewage of real meaning.
The utility model greatly reduces earthenware slab film by together with ozone-oxidizing device and earthenware slab film combination Replacement cycle, is greatly reduced the operating cost of whole device, have service life length, water treatment efficiency is good, construction cost and The advantages of operating cost is low.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model;
As shown in FIG.:1. water inlet;2. ozone oxidation tank;3. earthenware slab film;4. dosing tank;5. dosing pump;6. production Water pump;7. backwashing pump;8. Aeration fan;9. intermediate water tank;10. high-pressure pump;11. counter-infiltration system;12. ozone air inlet pipe.
Embodiment
As shown in Figure 1:2 one end of ozone oxidation tank is equipped with water inlet 1, and ozone air inlet pipe 12 is inserted into ozone oxidation tank 2, its bottom End extends to the bottom of ozone oxidation tank 2, and ozone oxidation tank 2 is internally provided with earthenware slab film 3, and earthenware slab film 3 passes through pipe Road is connected with the Aeration fan 8 outside ozone oxidation tank 2, backwashing pump 7, production water pump 6 respectively, and backwashing pump 7, production water pump 6 lead to respectively Cross pipeline intermediate water tank 9 to connect, intermediate water tank 9 is connected by high-pressure pump 10 with counter-infiltration system 11, and dosing tank 4 passes through dosing pump Pipeline between backwashing pump 7 and earthenware slab film 3 is connected, and the cleaning liquid of backwash is equipped with dosing tank.
