Description

[Detailed description of the invention] The present invention relates to a purifying agent for sewage, etc.

The purpose is to provide a purifying agent that is mainly made from volcanic ejecta and is highly effective in purifying sewage and the like.

Until now, there has been no definitively effective treatment agent for water treatment such as the purification of sewage and sewage, and the current situation is that the pollution of lakes, marshes, and rivers is increasing year by year, and effective countermeasures are awaited. .

In view of these circumstances, the present inventor has conducted extensive research, and found that there has been no example of using natural materials as active ingredients in water treatment agents, and that Kuroneji, which is made from volcanic ejecta, has excellent adsorption performance, deodorization performance, and The present invention was achieved as a result of focusing on the fact that it has agglomerating properties and studying how to utilize this property.

That is, sewage is characterized by having porous volcanic lapilli, volcanic ejecta as raw materials, volcanic ash, and activated carbon as active ingredients, which are mixed and bound together with a binder to form a lump. This led to the invention of purifying agents such as

The porous volcanic lapilli in the present invention is what is called volcanic pumice, and has a large number of pores of various sizes, which constitutes the 81 bodies of the purifying agent of the present invention.

In addition, Kuroneji in the present invention is made from volcanic ejecta and contains allophane and humic acid as its main components, which are the most important active ingredients for sewage treatment in the present invention.

This Kuroneji is obtained by separating and removing plant roots, gravel, etc. from volcanic ejecta and extracting mainly allophane and humic acid. For example, its manufacturing method involves using volcanic ejecta as a raw material, drying it using thermal power, cold air, or other means to remove the moisture content, then incinerating roots and other combustible materials, and then passing it through a sieve to remove sand, gravel, etc. The method that removes unnecessary substances and selectively collects a mixture of allophane and futominic acid as the main components has the highest yield. It is known as the method of construction.

Allophane is an inorganic clay mineral that contains a large amount of alumina. Since this alumina is a cation, it adsorbs anions and removes chromium ions and phosphate ions that cause red tan. However, under very acidic conditions, cationic allophane has the ability to convert to anions and also adsorb cations.

In addition, humic acid has an excellent deodorizing effect because it undergoes an ammoniato reaction with organic substances and produces ammonium humate, which is the source of odor.It also combines with calcium ions, cadmium ions, water lI+4 ions, etc., and removes hard water. It has the effect of softening water and sinking heavy metals.

Furthermore, this humic acid has V (quality) that adsorbs malodorous substances such as methyl mercaptan and methyl insol.

Furthermore, Kuroneji, which is mainly composed of a mixture of allophane and humic acid, is effective as a flocculant and has the effect of flocculating harmful substances and other undesirable substances.

As described above, the inner shell of the purifying agent of the present invention is also an important active ingredient in Kuroneji, but since it is earth-like and difficult to use as it is, in the present invention, it is incorporated into the pores of the parent volcanic lapilli. The most important feature of the present invention lies in the fact that it is integrated with the surface of the material.

Both volcanic ash and volcanic lapilli in the present invention are mainly composed of silicon oxide and aluminum oxide (alumina), and have ion adsorption ability by themselves, and it is well known that activated carbon is an excellent adsorbing substance. not.

These volcanic ash and activated carbon are blended to further strengthen and supplement the adsorption performance of the above-mentioned Kuroneji.A relatively large amount of volcanic ash ejected from the volcano is used, and this and the adsorption performance of activated carbon are used to decolorize.・It aims to make deodorization more effective.

According to the present invention, these volcanic ash, volcanic ash, and activated carbon are integrally bound to a base volcanic lapilli to form a lump, and cement, for example, is effective as the binder.

That is, as a method for producing the purifying agent of the present invention, volcanic lapilli,
For example, cement is mixed with a mixture of Kuroneji, volcanic ash, and activated carbon, water is added appropriately, and the mixture is kneaded to a thickness of 6 to 100 f.
It is formed into a flat plate shape of about f size, dried and hardened, and then divided into blocks of Ω (from the size of a pea to the size of a softball) as appropriate depending on the aquarium in which it will be used.

The purifying agent of the present invention is made of volcanic lapilli, which has pores of various sizes, and has excellent adsorption, deodorizing, and cohesive properties in the pores and on the uneven surface. This purifying agent is excellent because it contains a large amount of earth, volcanic ash, and activity bound together, and the pores of this matrix are porous enough to allow water and air to pass through. It has water permeability and breathability.

The mixing ratio of each component of the purifying agent in the present invention cannot be said to be a very important condition, but for example, when 100 parts by volume of volcanic lapilli is mixed, it is preferable that the amount of Kuroneji is usually 15 to 40 parts by volume; It is desirable to mix 15 to 35 parts by volume of activated carbon and 20 to 70 parts by volume of volcanic ash, and to use 30 to 70 parts by volume of cement to bind these.

Note that these numerical values are just examples, and the present invention is not limited to these blending ratios.

Next, a method of using the purifying agent of the present invention will be explained.

Since the purifying agent of the present invention is in the form of lumps, if a large number of them are submerged in a water tank and piled up, there will be many gaps between the layers, resulting in a very large contact area with water. It does not become cloudy and is extremely easy to use.

FIG. 1 is a side sectional view showing an example of how wastewater is treated using the purifying agent of the present invention.

As shown in this figure, approximately 6 liters of the purifying agent (2) of the present invention is added to the water tank (11).
They are stacked up to the 7th minute, and a pipe (3) is installed at the bottom to blow out compressed air. Then, it is filled with dirty water (a) and air is blown out from the hole (4) of the pipe (3) for a predetermined period of time.

The waste water passes through the pores and surface of the purifying agent (2) together with the ejected air, and is circulated for a predetermined period of time while being purified, eventually turning into extremely clean water.

As explained above in detail, the present invention is made by mixing and binding volcanic lapilli, Kuroneji, volcanic ash, and activated carbon together with a binder to form a lump. The powder and granules could not be used effectively as they were, but by using volcanic lapilli as a base material, the porous nature of the material was used to make it possible to treat water very efficiently, making it an excellent product. It fully exhibits adsorption performance, deodorization performance, decolorization performance, and coagulation performance, and brings about an epoch-making effect in tIj water purification.

Example volcanic lapilli 10C) Yoseibu volcanic ash 50 volumes Kuronechi 25 volumes Activated carbon 25 volumes Cement 5 parts by volume A mixture of the above composition was kneaded with water and formed into a shape with a thickness of 8α, Dry and cure. Divide this and the average diameter is approximately 5
It was made into a mass of purifying agent about the size of ax.

This material was piled up to about 7 minutes in a water tank with an internal volume of 30 mm as shown in Fig. 1.

In this case, the effective volume of clarifier was about 55 inches of the aquarium.

The sewage was then flowed in until it was nearly full, and air was blown out through the pipe at the bottom at a rate of 5 m3/min. This continued for 6 hours, and the sewage was circulated and treated by blowing air.

As a result, the purification effects shown in the following table were obtained.

(Note: This data was actually measured at the Kochi Prefecture Septic Tank Inspection Center, and is fully reliable.)

As shown in this table, highly contaminated raw sewage, which is judged to be on the same level as sewage, is transformed into considerably clean water after only 6 hours of treatment, demonstrating that the purifying agent of the present invention is extremely effective. It is.

Additionally, these results show that the purification of water in lakes, marshes, and rivers, which has a lower degree of βj staining than sewage, achieves the purification purpose in a fairly short time, and red tide and heavy metals are almost completely removed due to the effects of Kuroneji. It is determined that it can be removed.
