Definitions
- This invention is based on the discovery of fine particles (eg, dioxin, bacterium, etc.) such as, for example, wastewater from incinerator power plants.
- Fine particles eg, dioxin, bacterium, etc.
- BACKGROUND ART Conventionally, filtration of wastewater containing extremely fine particles such as 0.1 m cannot be performed even in a ceramic file having a large number of fine pores. However, there was no countermeasure to remove it with hollow yarn. In addition, the running cost of the work to solve the clogging of the evening was quite high.
- fine particles are coagulated and settled by injecting an aluminum or magnesium coagulant into the waste liquid.
- the sedimented sediment was removed by filtration in a press filter.
- At least a basic magnesium sulfate and a hydroxylated magnesium are formed between the first and second filtration layers.
- the fine particles in the liquid to be treated to aggregate (aggregate) to form a large lump the fine particles are captured by the second filtration layer. And purify it.
- fine particles in the liquid to be purified can be removed without using a large amount of a coagulant, and the coarseness of the particles is about 100 times the size of the fine particles to be removed. It was possible to capture and remove with a filter of the size.
- purification is defined as simple filtration by a filter, that is, the passage of the liquid to be treated through a gap of a fixed size. Rather than trapping the particulate matter in the gaps, the target substance is formed into a lump of size that is agglomerated and then It means to capture in the gap.
- At least a basic magnesium sulfate and a magnesium hydroxide are provided between the first and second filtration layers.
- an adsorbent consisting of um
- the gold in the treated liquid can be passed.
- the metal ions, especially heavy metal ions are combined with the hydroxyl groups of the adsorbent and solidified (blocked), and the solidified particles are aggregated ( ⁇ ).
- Grigate To provide a treated liquid purification device that is made into a large lump and then captured in the second filtration layer.
- At least a basic magnesium sulfate and a hydroxide magnesium are provided between the first and second filtration layers.
- An adsorbent such as a nebulium and a porcelain, is installed, a direct current is applied to the liquid to be treated by the electrode device, and OH ions are applied to the liquid to be treated. Then, the OH ion, the hydroxyl group of the adsorbent, and the metal or heavy metal ion in the liquid to be treated are bonded to form a solid.
- the particles are formed (flocked) and the solidified particles are agglomerated (aggregated) to form large agglomerates, they are passed through a second filtration layer. I tried to catch it. As a result, it is possible to remove metal or heavy metal ions in the liquid to be treated with an inexpensive device without using a chelating agent or a flocculant. .
- an absorbent made of cellulose powder is installed between the first and second filtration layers, and the electrode device is used.
- a direct current is passed through the liquid to be treated to generate ⁇ H ions in the liquid to be treated, and the OH ions and the metals or metals in the liquid to be treated are generated.
- the metal ions are combined with the heavy metal ion to form a solid (block), and the solid particles are captured by the sorbent and the second filtration layer. I did it.
- FIG. 1 is a cross-sectional side view showing an embodiment of a liquid purifying apparatus for processing according to the present invention.
- Fig. 2 is a potential energy characteristic curve.
- Figure 3 is a diagram showing the metal content of the silicon electrolysis waste liquid before purification by an X-ray microanalyzer.
- FIG. 4 is a diagram of the metal content of an X-ray mic opening analyzer with three repetitions of purification according to the embodiment of Fig. 1
- Fig. 5 is a diagram.

- the distance L between the fine particles A and B in the liquid to be treated shown in FIG. 2 is less than the distance L 2 from the distance Li and the fine particles A and B in the liquid to be treated.
- the attractive force P 2 acts between each other, and the particles aggregate together to form a large lump of about 300 times in size. This was confirmed by joint research with Osaka Municipal Industrial Research Institute.
- the large agglomerates of the fine particles are separated from the fine particles by a coarser second filtration layer 4 (more adsorbent 5 than the adsorbent 5). Which is located downstream).
- the second filtration layer 4 would have a diameter of 10 m. You can get rid of them if you use the field.
- filter paper having a mesh of 100 m was used as the first filtration layer 3. These meshes are made of adsorbent 5, It may be powdery or condylar or finer than granular.
- the gap between the powders is so narrow that clogging may occur in the gap.
- the specific gravity is close to that of the adsorbent 5, for example, by using granular activated carbon or the like as a spacer, the gap between the adsorbents 5 is used. You can prevent clogging by widening. Even if the spacer is inserted and the gap is enlarged, the operation of the absorbent described below is not impaired.
- a cartridge filter having a thickness of 10 zm was used as the second filtration layer 4.
- the measurement method used the method of January 1978, established by Nitto Denki Kogyo Co., Ltd. in Japan.
- heavy metal ions such as lead in the liquid to be treated may cause the powdery or condyle granular or granular interstices of the adsorbent 5. After passing through, the lead ion binds to the hydroxyl group of the adsorbent 5 to form the following [Chemical Formula 6]
- FIGS. 3, 4, and 5 show graphs of the metal-containing state obtained by an X-ray aperture analyzer using the embodiment apparatus of FIG. .
- Fig. 3 shows the metal-containing components in the unpurified silicon electrolysis effluent

- FIG. 5 shows a second filtration layer 4 of 10 m in which the metal-containing component of the purified liquid having three purification times when the filter was purified using a filter was used. Purified using the cartridge file of the above, and the metal-containing components of the purified liquid after 20 times of circulation filtration are shown.
- FIG. 6 is a side sectional view showing a second embodiment of the present invention, and is made of the same dimensional material as that of FIG.
- the electrode 6 is formed in a mesh shape, for example, and the container 1 is used as an earth electrode, and a DC voltage of, for example, +2 V is applied.
- the electrode device is composed of the electrode 6 and the container 1.
- the adsorbent 5 the same one as in the first embodiment is used.
- the liquid to be treated in the container 1 is supplied with the direct current of 4.5 thigh A.
- this direct current value hydrogen gas, Oxygen gas is not generated, and H ion and ⁇ H ion are generated as shown in the following chemical formula 8.
- the OH ion and the hydroxyl group of the adsorbent 5 combine with the heavy metal ion in the waste liquid to solidify the heavy metal ion as described above (fluoro).
- the solidified particles are aggregated (aggregated) by the adsorbent 5 and then captured by the second filtration layer 4. '
- the case where a DC voltage is applied between the electrode 6 and the container 1 made of a conductor is shown, but as an alternative, the DC voltage is applied separately from the container 1. You may have a ground electrode or a single electrode.
- the first filter layer 3 consisting of 100 m of filter paper is converted to a mesh electrode of 100 O ⁇ m mesh stainless steel.
- the electrode 6 may be omitted.
- the case where a DC voltage of +2 V is applied is shown, but what is important is not the voltage value but the chemical formula 8 This is the current value for generating OH ions.
- a preferable current value is about 4.5 mA, and the maximum current value permitted by the other party is determined by hydrogen gas. It is up to about 23 mA.
- FIG. 7 is a side sectional view showing a third embodiment of the present invention.
