Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a purified wastewater treatment device, particularly when filth is decomposed by microorganisms and the purified liquid is discharged.

This invention relates to a system in which wastewater treatment is performed by forcibly evaporating the purifying liquid without discharging the purifying liquid into a U-shaped groove.

[Background, conventional technology and problems]

For example, sewage systems and sewage treatment plants are installed to treat human waste, but in cases where a sewage system is not fully equipped, the waste is collected by pumping or a septic tank is installed for purification. In order to make life more comfortable, the installation of septic tanks that can be used with flush toilets has become widespread.

There are also different types of septic tanks, such as independent septic tanks, and there are three types of independent septic tanks:

■ Complete treatment method ■ Separation treatment method ■ Contact treatment method Among these methods, the separation treatment method septic tank, which has recently been developed and is widely used, will be briefly explained based on Figure 1.

The inside of the septic tank 1 is partitioned by a partition plate 2 and a buckle plate 3.
It is roughly divided into a precipitation separation chamber A, an aeration chamber B, and a precipitation chamber C.

The sediment separation chamber A is provided with an inflow pipe 4 and a vertical pipe 5 connected to the toilet bowl, and the sediment separation chamber A and the air chamber 3 are connected by a connecting pipe 6.

A disinfectant injector 7 is installed in the upper part of the precipitation chamber O.

The purified water discharged from the settling chamber 0 is disinfected thereby and flows out into the W-shaped groove 9 via the drain pipe 8.

Of course, the septic tank 1 is covered with a lid 10.

Therefore, in the case of gAJ, excrement flows from the flush toilet in the home through the inflow pipe 4 and vertical pipe 5 into the sedimentation separation chamber A, where concentrated organic matter and impurities are precipitated, and the precipitate becomes anaerobic. Purified by microorganisms. The intermediate water in the precipitation separation chamber A is discharged to the aeration chamber B via the connecting pipe 6. The aeration chamber B is equipped with an aeration pipe (9 not shown), which is stirred to activate the activity of aerobic microorganisms and efficiently dissolve oxygen into the water. This increases the activity of microorganisms in the chamber B, which decomposes organic matter. and,
The sludge in this purified liquid is settled in a settling chamber C.

The purifying liquid is sterilized by a disinfectant injector 7 to sterilize E. coli and the like, and then drained into a U-shaped groove or the like.

Also, in the contact force type, as shown in Fig. 2.

A septic tank 20 is partitioned into a sediment separation chamber A and an aeration chamber by a partition plate 21, and a large number of pebbles 23 are arranged in the aeration chamber to form a purification chamber. When waste water is sprinkled onto the pebbles 23 from the sedimentation separation chamber A through the connecting pipe 22.

Since a microbial film exists on the surface of each pebble 23, the filth is decomposed by these microorganisms, and the purifying liquid is discharged by the pump 24 into a U-shaped groove (not shown in FIG. 2).

In addition, in the above-mentioned full-air type (①), the partition plate 2 is omitted in Fig. 1, and the inside of the septic tank is not differentiated into a sedimentation separation chamber and an air-air chamber, but instead consists of an air-air chamber and a settling chamber. Since it has been widely used for a long time, its explanation will be omitted.

In this way, the septic tanks currently in use are fully equipped with drainage means such as U-shaped grooves, have good functionality, and the BOD value of the discharged water is below the legal value (for example, the number of people to be treated is 1.
If the daily average concentration is 90 ppm or less in facilities with a temperature of 00 Å or less, wastewater can be discharged.

However, in areas where there is no suitable drainage destination9, such as areas where wastewater is discharged into agricultural water, areas where drainage equipment has not been installed, or where the septic tank is malfunctioning and legal discharge water quality cannot be maintained, etc. Even if a septic tank is commercially available, it is not easy to use it.

For example, when there is no suitable drainage destination, equipment as shown in FIG. 3 is used. Hole 40-1...4 in the ground
0-n, the large surface of which is covered with a vinyl channel 41, and an aeration pipe 42 and a sewage diffusion pipe 43-1.・
...43-ru (the wastewater diffusion pipe close to the separation and filtration species 30 is thick) is arranged, and these are buried with pebbles 44. An evapotranspiration treatment facility is used that covers the surface of the pebbles 44 with soil 45 to form an evaporation surface. In this case, the sewage is separated and filtered in the separation filtration process 30 and then sprinkled through the sewage diffusion pipes 43-1...43-. The organic matter is then processed by microorganisms, and the water rises to the soil surface through capillary action, becoming kernels that are naturally evaporated by sunlight and other factors.

Such equipment requires a large installation area, cannot be used in areas where the groundwater level is low, has insufficient evaporation capacity in areas with poor conditions, and may clog and become defective, so 50t// It is not suitable for general household use, which requires the treatment of wastewater of A-day.Therefore, there is a need to develop a purification system that can be used in places where there is no drainage destination or where the capacity of the septic tank is insufficient. Ta.

[Purpose of the invention]

An object of the present invention is to provide a purified wastewater treatment apparatus that allows a septic tank to be used even in places without drainage facilities such as U-shaped ditches.

Another object of the present invention is to provide a purified wastewater treatment device that can discharge wastewater even if the capacity of the septic tank does not meet the legal value.

[Structure of the invention]

In order to achieve such an objective, the purified wastewater treatment apparatus of the present invention decomposes waste materials using microorganisms.

In a purification device equipped with a purification liquid discharge part for discharging the purification liquid, a purification liquid reservoir part for storing the purification liquid is provided, and a purification liquid evaporation means for forcibly evaporating the purification liquid is provided in the purification liquid reservoir part, It is characterized in that the purification liquid is drained by forcibly evaporating the purification liquid from the purification liquid reservoir.

[Embodiments of the invention]

An embodiment of the present invention will be described based on FIGS. 4 and 5.

FIG. 4 shows a purification device to which the purified waste water treatment device according to the present invention is added, and FIG. 5 shows the detailed structure of one embodiment of the purified waste water treatment device of the present invention.

In the figure, the same reference numerals as in other figures indicate the same parts.

50 is a drain pipe, 51 is an evaporation tank, 52 is a waste water evaporator, 53
is the ultrasonic generator, 54 is the float, 55.56 is the hole, 57
58 is an automatic switch, and 59 is a steam exhaust hole.

The wastewater evaporator 52 evaporates the wastewater in the evaporation tank 51, and the ultrasonic generator 53. Float 54° Evaporating dish 57.
It has an automatic switch 58 and the like. Here, the ultrasonic generator 53
The device generates ultrasonic waves when the automatic switch 58 is turned on to evaporate the water on the evaporating dish 57, and has an ultrasonic diaphragm for this purpose.

Now, in the septic tank 1 in FIG. 4, the excrement that has flowed into the septic tank 1 yen via the inflow pipe 4 and the vertical pipe 5 is as follows:
First, it is subjected to a primary process of putrefaction by anaerobic microorganisms in a sedimentation separation chamber A, and then subjected to a secondary process of oxidation treatment by aerobic microorganisms in an aeration tank B. Air is sent to the aeration tank B through a porous aeration pipe, etc. (not shown).

Effectively dissolves air into water and activates microbial activity. After being subjected to secondary processing in this way.

After the purified liquid is disinfected by the disinfectant injector 7 from the settling chamber C, it is discharged into the evaporation tank 51 via the drain pipe 50.

A wastewater evaporator 52 having a float 54 is installed in the evaporation tank 51, so when the purification liquid flows into the evaporation tank 51 to a certain extent, the wastewater evaporator 52 floats on the purification liquid, and as a result, an automatic switch is activated. 58 is turned on, and the ultrasonic generator 5
3 starts operating, the ultrasonic oscillator S generates ultrasonic waves,
The water on the evaporating dish 57 is evaporated. The steam generated by the ultrasonic waves thus generated is discharged to the outside air from the steam exhaust hole 59. In addition, since the purification liquid is continuously flowed into the evaporation dish 57 via the holes 55 and 56, steam is also continuously generated, and as a result, the steam that has flowed in from the septic tank 1 is also continuously generated. Even without a drainage facility such as a U-shaped groove, the purifying liquid can be vaporized into the air, subjected to tertiary treatment, and then discharged.

As shown by dotted lines in FIG. 5, a partition plate 60 having a hole 61 is provided, and the purified liquid flowing directly from the drain pipe 50 is injected into the waste water evaporator 52 floating on the float 54 from 1'. This can be prevented.

In addition, as shown in FIG. 6, the steam exhaust hole 59 of the evaporation tank 51
It is also possible to install an exhaust fan 62 above to actively exhaust the steam generated from the water evaporator 52 into the outside air.

In the above embodiment, an example was described in which a waste water evaporator having an ultrasonic generating section was used as the purification liquid evaporation means, but the purification liquid evaporation means is of course not limited to this. For example, it may be vaporized using an electric heating element or other heating means.

Furthermore, if the water that has been vaporized by the above-mentioned evaporation means is condensed and restored to water, this restored water has almost no impurities and satisfies drainage standards, and can not only be discharged into agricultural water. .

You can freely dispose of it by returning it to the ground or discharging it into a pond. Therefore, by using this tertiary treatment device, wastewater treatment can be performed even in a septic tank with insufficient purification ability.

〔Effect of the invention〕

According to the present invention, purified water can be evaporated regardless of the type of septic tank, so that sewage can be treated without adversely affecting the surrounding environment.

Moreover, because this evaporation equipment is small, it requires a much smaller installation area than evaporation equipment that uses natural conditions, so it can be used in areas where septic tanks could not be used due to inadequate wastewater treatment facilities. You can use it extremely easily and enjoy a comfortable daily life.
