Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical effluent treatment apparatus for hospitals and clinics that perform artificial dialysis treatment.

[0002]

2. Description of the Related Art As a conventional wastewater treatment apparatus, there is a pH neutralizing apparatus. This pH neutralizer injects an acid or alkali chemical solution as a neutralization method, and supplies a hydrogen ion concentration [pH]
Is adjusted for wastewater treatment.

[0003]

In the case of a conventional waste water treatment apparatus, a certain amount of sulfuric acid and sodium hydroxide (caustic soda) must be stored in order to inject and treat a chemical solution. However, regarding the handling, there are some places that are surrounded by net fences or the like because of the danger, but they are often installed in places where children may mischief. Therefore, depending on the hospital and clinic,
Many facilities are hesitant to install or discharge untreated water, causing corrosion and damage to sewer pipes.

In addition, this wastewater treatment apparatus cannot be treated unless chemicals are added to wastewater again in order to satisfy the exclusion criteria for sewerage.

[0005] The main object of the present invention is to make it possible to meet the exclusion criteria for sewerage without using dangerous chemicals.
An H adjusting device is provided.

In addition, the present invention allows conventional hospitals and clinics to actively work on wastewater treatment, and hopes that at least some facilities will meet the sewage exclusion criteria and protect the natural environment. Can contribute to it.

[0007]

In order to solve the above-mentioned problems, a dialysis effluent pH adjusting device according to the present invention uses a safe solid pH adjusting agent, adjusts the loading amount, and allows the effluent to pass through. In this method, the pH is adjusted and released.

[0008]

The dialysis wastewater pH adjusting device according to the present invention can be small and light, and can be installed even in a narrow place. Even in hospitals and clinics that could not be set up because of being occupied in a tenant building up to now, they can be set up indoors and outdoors if there is only a small amount of space. For example, it can be attached to a gap in a pipe shaft, a ceiling, or the like if there is an empty space. Therefore, it can be installed even in a conventional facility where wastewater treatment has not been possible so far, thereby contributing to the problem of sewer pollution.
In addition, the dialysis effluent pH adjusting device according to the present invention does not require a motor, a pump, and the like, and thus does not require power costs. And there is no cost for machine maintenance. Therefore, both initial cost and running cost can be suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dialysis wastewater pH adjusting apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a schematic front view of a dialysis wastewater pH adjusting device according to an embodiment of the present invention, FIG. 2 is a schematic side view of the dialysis wastewater pH adjusting device according to an embodiment of the present invention, and FIG. PH of the dialysis wastewater pH controller according to the embodiment of the present invention
FIG. 4 is a schematic cross-sectional view of a regulator, FIG. 4 is a schematic top plan view of a pH controller of a dialysis drainage pH controller according to an embodiment of the present invention, and FIG. 5 is a dialysis drainage pH control according to an embodiment of the present invention. FIG. 6 is a schematic lower cross-sectional view of a pH adjuster of the dialysis drainage pH adjuster according to the embodiment of the present invention.

As shown in FIG. 1, a dialysis wastewater pH adjusting apparatus according to an embodiment of the present invention comprises a pH adjusting device 2, a straight vinyl chloride pipe 3, a hard vinyl chloride pipe joint 4, and
It is formed by the valve 5 and the flange joint 10 and is connected to the main drainage pipe 1 at the end and discharged.

A straight PVC pipe 3 is wound around a U-bolt 7 and attached to a bracket 6 by means of a U-bolt 7. The bracket is fixed to a wall or a beam of a building with an anchor bolt to maintain reinforcement and stability. It is.

The pH controller 2 is a stainless steel reinforced angle 1
3, the bracket 6 can be fixed to the bracket 6 by bolting, and the bracket 6 can be fixed to a building wall or a beam type with an anchor bolt.

The pH adjuster 2 is formed in a semi-cylindrical shape by a stainless steel plate 12, a stainless steel reinforcing angle 13, a stainless steel tube 14, a stainless steel mesh 15, and a flange joint 10, and has a structure in which a solid pH adjuster 16 is charged. It has become.

The valve 5 is used to check the volume of the solid pH adjuster 16 in the pH adjuster 2 by opening the stainless steel inspection port 11 or to close the valve when adding the solid pH adjuster 16 for adjustment.

The bypass pipe line is formed by combining the hard vinyl chloride pipe joint 4 and the hard vinyl chloride pipe straight pipe 3, and in order to prevent the drain water from flowing backward at the time of inspection or when a failure such as clogging occurs. A cleaning port 8 is attached to the top.

At the lower part of the pH controller 2, a measuring port 9 using a hard vinyl chloride pipe joint 4 is provided, and a cleaning port cap is removed to measure pH.

[0018]

As described above, the pH adjusting device for dialysis wastewater according to the present invention is a stainless steel plate and a steel plate or
Made of FRP, made of polyethylene, cylindrical and semi-cylindrical, or formed into a box, loaded with a solid pH adjuster inside,
The hydrogen ion concentration [pH] is adjusted by dissolving the solid pH adjuster through the void.

Therefore, the dialysis effluent pH adjusting device according to the present invention adjusts the volume of the solid pH adjusting agent to be charged, and after the effluent having a different hydrogen ion concentration [pH] passes, the effluent does not meet the sewage exclusion criteria. And the sewage can be discharged. In particular, disinfectants with low hydrogen ion concentration (pH) and
When a cleaning agent was used, it was directly discharged in the past, and the sewage sewer buried on the road was corroded and damaged by strong acid substances, causing a damage accident. Since the sewage can be discharged by adjusting the hydrogen ion concentration [pH] by the adjusting device, the sewage pipe is not adversely affected.

The dialysis effluent pH adjusting device according to the present invention does not require a motor, a pump, etc., so that the power cost is also reduced.
There is no cost for machine maintenance.
