Description Water quality improving agent and its production method

The present invention is intended to improve various types of pollution related to sewage, odor, and other water in rivers, lakes, marshes, dams, sewers, septic tanks, recirculating flush toilets, temporary toilets, night soil treatment plants, the sea, factory drainage, etc. The present invention relates to a water quality improving agent capable of decomposing sludge and a method for producing the same. Background art

Conventionally, rivers, etc., have been equipped with sewage treatment plants that use ultraviolet light, etc., to deal with various types of pollution, and ordinary households and factories have used filtration, sedimentation, etc. to deal with the wastewater. Septic tanks are used. In addition, at landfills by local governments, carbon and other chemicals are injected, and sludge is removed by dredging.

However, facilities such as sewage treatment plants are very expensive, and it is very difficult to deal with them if the amount of treated water exceeds the allowable capacity. When chemicals are used, adverse effects such as side effects are considered. Furthermore, the sludge removed by dredging etc. is transported to another place for treatment, so strict management is required, and a separate treatment plant is required. Furthermore, at present, along with such projects, legal regulations for improving the water environment are being strengthened, and there is an urgent need to develop water quality improvers that comply with such regulations.

An object of the present invention is to provide a water quality improving agent capable of easily improving water quality and decomposing organic sludge in rivers, lakes, marshes, ponds, dams, etc. without impairing the surrounding landscape, and a method for producing the same. Is to do. Disclosure of the invention

The inventors of the present invention have made intensive studies to achieve the above object, and as a result, have completed the present invention. That is, the water quality improving agent of the present invention The enzyme is obtained by adding the extracted enzyme and minerals extracted from minerals containing magnesium and calcium containing silicon as a main component to water and stirring at a predetermined temperature for 30 to 90 minutes.

(Preparation method)

Cut the oranges into the appropriate size with the skin on, put in a 5 liter container with the above ingredients, add water until the total volume is 5 liters, and heat to boiling. Leave it in this container and let it mature at room temperature for about 6 months. Then add water to the 5 liter scale and heat at 80 ° C to 100 ° C for about 90 minutes. Then, let it stand at room temperature and collect the supernatant to obtain about 3 liters of extract. This extract (10 cc) and 300 g of dried masago are mixed with 10 liters of water, kept in a sealed state for about 2 to 3 weeks, and the supernatant is taken out. This is the undiluted water of the enzyme extracted from orange.

The enzyme used in the water quality improving agent of the present invention is not limited to the above composition, and may be prepared by mixing pineapple with orange. [1-2. Preparation of Mineral Extract]

(Composition)

Masago 1 0 0 0 g

Amphibolite 100 g

Cunic acid 250 g

(Preparation method)

Dissolve each of the above components in 10 liters of water and heat for about 90 minutes near the boiling point. Then leave it at room temperature and remove the supernatant. This is the mineral extract-[13. Preparation of water quality improver]

100 cc of the stock solution of the enzyme extracted from orange prepared as described above is diluted 20-fold with water, and the above mineral extract is added to the extract at 1 to 10 cc. After stirring for about 30 minutes, the mixture is further diluted 200 to 250 times with water and stirred.

The stirring time for producing the water quality improving agent of the present invention in 500 liters is usually 60 minutes, but depending on the conditions of the water to be improved and the cause of contamination, etc. It can be changed arbitrarily in 90 minutes. The stirring time can be appropriately changed depending on the production amount of the water quality improver and the stirring capacity of the stirrer. Therefore, when the stirring capacity of the stirrer is large, a large amount of the water quality improving agent can be produced in a short time. [2. Enzymes]

Enzymes that can be used in the water quality improver of the present invention can be obtained not only from the above-described enzymes extracted from oranges, but also from fruits such as pineapples, Pomegranate, and other plants. In this case, pineapple can be used alone as in the above orange, and the extraction method is also the same. Alternatively, orange and pineapple may be used in a one-to-one mixture. In addition, it is considered that Pseudomonas radiata has an effect of promoting extraction.

[3. Minerals]

The minerals extracted from the above minerals are magnesium, It is a shim or other composite, preferably in a liquid form, but may be in a granular form. In addition, these minerals generate bioelectricity and active potential in the living organisms of the aquatic organisms that make up the biological circulation chain to improve ionization, activate cells, and improve hormonal balance. It is thought that this has the effect of promoting the propagation of aquatic organisms that constitute the biological cycle.

[4. Enzyme and Mineral Mixing Ratio]

The mixing ratio of the above enzymes and minerals is usually in the range of 10 to 16 minerals per enzyme in terms of mass, but the mixing ratio is optional according to the conditions of water to be improved and the cause of contamination. Can be changed. For example, if the cause of contamination is high oil content, it is effective to increase the mineral ratio, such as 30 or more minerals per enzyme. Either enzyme or mineral may be used, and minerals may not be used in ordinary rivers and ponds.

[5. Application method]

For example, in rivers, etc., water flows from upstream to downstream, so there is almost no stagnant water. If the water quality needs to be improved in such a flowing situation, it is desirable to use drip injection. Also, in rivers, etc., the drip interval and dose are determined based on the daily flow rate (for example, if the daily flow rate is 10,000 tons, the drip interval is every 1 second, and the input rate is 67 liters / Days are preferred). On the other hand, in the case of dams, etc., the water at the bottom is always stagnant, so it is effective to inject directly into the bottom of the dam.

Here, the method of introducing the water quality improving agent of the present invention will be described with reference to the drawings. (a) Infusion method

As shown in Fig. 1 (A), a water quality improving agent is stored in a storage tank 1 having an anti-freezing function, a pump 2 is connected to the storage tank 1, and a pump 2 is connected via a common pipe 3 to a knee. Connected to dollar nozzle 4. Then, a required amount of the water quality improving agent is sent to the common pipe 3 by the pump 2, and the water quality improving agent is discharged from the needle nozzle 4 provided at the end of the common pipe 3. The 21 dollar nozzle 4 has a flow rate An adjuster is provided so that the drip interval can be adjusted as appropriate.In the drip method as described above, the needle nozzle needs to be adjusted according to the size of the river and the type of purification target such as a pond or dam. The amount of water quality improver can be adjusted by increasing or decreasing the number of installations. Needless to say, the method can be combined with an intermittent method in which charging is performed at predetermined time intervals.

(b) Spray method

As shown in FIG. 1 (B), in the spraying method, a spraying nozzle 5 is attached to the tip of the common pipe 3. Note that the spray nozzle 5 is also provided with a flow rate adjuster, so that the spray interval can be appropriately adjusted. The other configuration is the same as that of the infusion method, and the description is omitted.

(c) Direct injection method

The direct injection method is applied to deep ponds. In other words, in the direct injection method, the purification efficiency can be increased by submerging the common pipe to a desired depth and directly charging the water quality improving agent into the common pipe.

(d) Fountain method

As shown in FIG. 1 (C), in the fountain method, a round or straight fountain type nozzle 6 is attached to the tip of the common pipe 3. The fountain-type nozzle 6 is also provided with a flow rate regulator so that the discharge interval can be adjusted appropriately. The other configuration is the same as that of the infusion method, and the description is omitted.

The fountain method is used when the water flow is weak, such as in a pond.

In this way, the injection method such as drip injection, intermittent injection, spraying, direct injection, etc. is determined according to various conditions such as the type of the object to be improved. Also, multiple systems can be used together, and can be used with existing facilities.

[6. Action / Effect]

By appropriately adding the water quality improving agent of the present invention, effects such as a decrease in BOD, COD, turbidity, and chromaticity, an improvement in odor, and a decomposition of chlorine compounds and organic substances were obtained. This action is an active action, and the river improved by the water quality improving agent of the present invention. In rivers, lakes and marshes, it is thought that this will lead to the activation of self-cleaning, which is effective for preserving ecosystems. BRIEF DESCRIPTION OF THE FIGURES

Later, about 10 liters were directly injected into points D and E, respectively. That is, a total of 80 liters were injected using both infusion and direct injection. The experimental period was about 2 months.

[Experimental result]

About one month after the start of the experiment, it was confirmed that the degree of transparency had improved. About two months after the start of the experiment, the degree of transparency improved as the pond bottom was clearly visible, and there were no abnormalities in living things such as carps.

[Example 2] [experimental method]

The object of the experiment was two ponds with a circumference of about 150 m and a water depth of about 50 cm as shown in Fig. 3, both of which were about 3π! The ₃ this pond you are away ~ 5 m is transplanted aquatic plants, have been made education. The water in the two ponds is spring water that springs from the bottom of the ponds. The ranch's pastures around the pond are rich in nutrients, so that amidro breed enough to cover the water surface of the pond and hinder the growth of aquatic plants. Therefore, in Example 2, the purpose of the experiment was set as “suppression of the propagation of ambero.”

As an experimental method, one of the two ponds with a surrounding area of about 150 m and a water depth of about 50 cm was treated, and the other was left untreated and compared.

First, immediately after the start of the experiment, 40 liters of the water quality improver of the present invention were sprayed on the surface of the pond while walking around the pond to be treated in the direction of the arrow in the figure, and a week later, an additional 40 liters were applied. They were sprayed in the same manner as in the case of a little, and a total of 80 liters were introduced. The experiment period is about one month.

[Experimental result]

Approximately 4 to 5 days after the start of the experiment, it was confirmed that aomidro breeding in untreated ponds and that vegetation was suppressed in the treated ponds. On day 10 after the start of the experiment, water was collected from each of the two ponds and weighed. The pH of the untreated ponds was 7.8 and the turbidity was 3.8. ρ Η 7.1 and turbidity 1.6 were improved. The growth of aquatic plants was also successful.

[Embodiment 3]
