Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of second level magnetic induction strengthens Fenton and reacts sewage
Processing unit and its method of sewage treatment.
Background technique
Magnetic field between magnetic pole is able to achieve electromagnetic energy and mechanical energy, the conversion of chemical energy and biological energy source.In its conversion process
Correspondingly generate mechanical effect, chemical effect, biological effect and nuclear magnetic resonance effects etc..It can be preferably real using these effects
The magnetization treatment of existing sewage, the experimental results showed that, magnetization treatment to many physicochemical properties of water (such as refractive index, conductivity,
Dielectric constant, surface tension, viscosity and infrared absorption spectrum etc.) all have an impact.These influence explanation, and magnetization treatment can make water knot
Structure changes；Metabolic process of the magnetic treatment to dissolution, crystallization, polymerization, wetting, cohesion, solidification, precipitation process and biosystem
Also it has an impact, magnetic treatment can be such that water system significantly activates and can influence the dynamic process of chemical reaction；Studying also found, magnetic
Field has apparent memory effect to the effect of water system, and (i.e. after removing external magnetic field, the physicochemical properties of water system can be protected
Hold a few hours or a couple of days).
H in Fenton reaction2O2In Fe2+Catalytic action under decompose and generate OH, oxidizing potential reaches 2.8V, OH
Oxidation operation is resolved into small molecule by approach such as electronics transfers.Meanwhile Fe2+It is oxidized to Fe3+Coagulating sedimentation is generated,
Remove large amount of organic.As it can be seen that Fenton reagent has oxidation and two kinds of effects of coagulation, while Fenton reagent in water process
Energy degradation of organic substances in the dark, saves equipment investment, the disadvantage is that H2O2Utilization rate it is not high, cannot sufficiently mineralising it is organic
Object.Research shows that same using the heterogeneous catalysis such as oxide mineral of the homogeneous catalysts such as Fe, Mn and iron powder, graphite, iron, manganese
Sample can make H2O2Decompose and generate OH, because its react basic process it is similar with Fenton reagent due to referred to as Fenton-like system.
Fenton method has the advantages that general chemical oxidization method is incomparable, so far when handling organic wastewater with difficult degradation thereby
The processing of various industrial sewage is successfully applied to.But H2O2It is expensive, it is too high that often cost is used alone, thus in reality
It in, is usually combined with other processing methods, is used for the pretreatment or ultimate depth processing of waste water.With a small amount of
Fenton reagent pre-processes industrial wastewater, makes the hardly degraded organic substance in waste water that partial oxidation occur, changes theirs
Biodegradability, dissolubility and coagulation performance are conducive to subsequent processing.In addition, some industrial wastewaters are after materialization, biochemical treatment, water
In still remain a small amount of bio-refractory organic matter, when water quality is not able to satisfy emission request, can be used Fenton method to its into
Row advanced treating.
So being used alone, magnetic force is poor for the treatment effect of dirty water pollutant, and magnetic force may only change water in sewage
The physical state of molecule can not reach preferable effect for the direct removal of the pollutants such as COD, ammonia nitrogen, and use
The processing of Fenton method using more, it is more to generate iron cement, and cannot reuse after use, easily cause waste for medicament.
Can illustrate that magnetization treatment is modified for sewage with this has effect, but it removes dirty pollutant in water
It removes and is not suitable for, and Fenton method effect is preferable, but iron cement yield is larger, both expensive.Problem of the existing technology is main
Have the following aspects: 1, Fenton method is costly using medicament, and generation iron cement is more, adds medicament not recoverable；
2, the extent of reaction of Fenton method is more difficult to control, and due to hydrogen peroxide volatility, should not once be added directly；3, magnetic field reaches threshold
Value is just understood effective, and when use needs certain magnetic field adjusting device and determines most suitable magnetic field strength；4, current magnetic force water
Processing is primarily adapted for use in magnetic flocculation, is not directed to the content that magnetic force strengthens advanced oxidation.
Summary of the invention

It is aerated the water flow propulsion that plug-flow pipe 3 carries out vertical and horizontal both direction, so that passing through the water (flow) direction of sewage under magnetic field environment
Change, flow velocity change, improve sewage carry out Fenton reaction efficiency, realize magnetization and Fenton reaction collaboration
Effect is obviously improved wastewater purification efficiency, reduces COD value.
Aeration plug-flow pipe 3 is replaced with blender in embodiment 3, although sewage is kept to continue Fenton in pond body 1
Reaction, but COD removal rate is obviously low compared with embodiment 2, analysis reason may be that the direction of the magnetic induction line of magnetic induction loop is mainly
It annular spread centered on 1 side wall of pond body and is distributed along the longitudinal axis of pond body 1, water flow spiral in adjustable diameter and screw adjusting pipe 4
When, hydro jet annular magnetic induction line, carries out the magnetization of the first order and Fenton reacts synergistic effect, improves Fenton reaction effect
Rate；When water flow is flowed to side in the aeration aeration promotion pond body 1 of plug-flow pipe 3, longitudinal magnetic strength of 1 center of hydro jet pond body
Line, carries out the magnetization of the second level and Fenton reacts synergistic effect, improves Fenton reaction efficiency；Second level magnetization adjustment effect makes

5. Fenton is strengthened in a kind of second level magnetic induction according to claim 1 reacts sewage-treatment plant, which is characterized in that
Distance of the outlet pipe (2) away from the pond body (1) bottom surface is the 1/3 to 1/2 of pond body (1) height.
6. Fenton is strengthened in a kind of second level magnetic induction according to claim 1 reacts sewage-treatment plant, which is characterized in that
Pond body (1) bottom is equipped with scum pipe (12).
7. it is a kind of according to claim 1 in -6 sewage-treatment plant sewage treatment described in any claim method, feature
It is, specifically includes the following steps:
1) power supply (7) of magnetic induction loop (8) is connected；
2) it adjusts the pH to 2.5-3.5 of pretreated water and Fe is added2+Nano-magnetic powder after, be pumped by the first dosing pump (6) pre-
It handles water inlet pipe (9) and enters adjustable diameter and screw adjusting pipe (4)；It rotates helical blade (4.1), and hydrogen peroxide is passed through into the second dosing pump (6)
Hydrogen peroxide chemical feed pipe (5) is continuously pumped into adjustable diameter and screw adjusting pipe (4), reaction obtains first order magnetization sewage；
3) first order magnetization sewage is gushed by the promotion of helical blade (4.1) from water outlet (11) in the adjustable diameter and screw adjusting pipe (4)
Out, interior into pond body (1), start several aeration plug-flow pipes (3) and be aerated, towards unidirectional solarization air cap (3.1)
The movement in pond body (1) of first order magnetization sewage is pushed to obtain second level magnetization sewage；
4) when pond body (1) interior liquid level rises to adjustable diameter and screw adjusting pipe (4) water outlet (11) position, stop pretreatment water inlet pipe (9)
The rotation of water inlet and helical blade (4.1), solarization air cap (3.1) continue after being aerated 20-30min, stop aeration, close power supply (7)；
It adjusts pond body (1) interior second level and magnetizes pH value of sewage water to 7.0-7.5, after staticly settling, open the outlet pipe (2) valve from out
Water pipe (2) discharge, water after being handled；
5) second level remaining in pond body (1) is magnetized by sewage by scum pipe (12) and dregs drains collection.
