Description

[Detailed description of the invention] (Industrial application field) This invention is a method of floating a waste liquid reservoir or a river, and discharging the chemical liquid (deodorizing liquid, insecticidal liquid, algaecide liquid, etc.) contained in the container body into the chemical liquid and sewage water. is gradually discharged into wastewater through an appropriate mesh flow rate adjustment network according to the concentration difference.
The present invention relates to a float-type chemical solution underwater diffuser that prevents bad odors from sewage, exterminates pests living in sewage, and prevents the growth of algae.

(Prior art) Conventionally, deodorization of polluted water such as waste liquid reservoirs or rivers, etc., and pest control have been carried out by continuously or intermittently injecting deodorants, insecticides, or algaecides into waste water. There is.

(Problems to be solved by the invention) However, the above method requires a large amount of drugs;
Moreover, it is extremely uneconomical because it is unstable, and it requires a great deal of labor and time to introduce the drug.
There were problems such as high concentrations of chemicals concentrating at the injection point at one time, causing damage to beneficial or harmless wildlife in the surrounding area.

(Means for solving the problem) The present invention aims to solve the above-mentioned problem. or algaecide solution)
The lower opening of the water passage hole is covered with a flow rate adjustment net of suitable mesh, and the container is floated in a waste liquid reservoir or river with the water passage hole side facing downward, and the inside of the container is kept airtight. The chemical solution stored in the container body is gradually discharged and diffused into the wastewater through a flow rate adjustment network according to the concentration difference with the wastewater outside the container, and the chemical solution is replaced by the chemical solution by reducing the pressure of the air layer inside the container body due to the discharge of the chemical solution. Float-type chemical liquid submersible system that effectively purifies wastewater by continuing to release chemical liquid over a long period of time until the concentration of the liquid inside the container, which is diluted by the sewage that has entered the container, becomes equal to the concentration of external sewage water. It is a diffuser.

The present invention will be explained below with reference to embodiments shown in the drawings.

Configuration From Figures 1 and 2, the upper part has a handle 1 at the top end.
The hollow container body 4 has a container outer peripheral wall 2 having an appropriate shape (the figure shows a spherical shape) and a cylindrical peripheral wall 3 at the lower part. A weight locking protrusion 5 that bulges in the direction is provided around the circumference,
A screw 6 is provided on the outer peripheral surface below the middle, and
The lower end peripheral wall portion is integrally molded from a synthetic resin material so as to form a cylindrical inner lid body fitting portion 7.

The weight 9 has an outer diameter that can be inserted into and removed from the cylindrical peripheral wall 3 of the hollow container body 4, and has a water passage hole 8 in the center in the axial direction. It is inserted so that the peripheral edge contacts and locks the lower surface of the weight locking protrusion 5.

The outer peripheral edge portion is a disc-shaped annular groove portion 10 with an open upper part into which the inner lid fitting portion 7 formed at the lower end of the cylindrical peripheral wall portion 3 is fitted, and the bottom surface is inward from the groove portion 10. The inner lid body 13, which has a circular concave portion 11 and a through hole 12 having the same diameter as the water passage hole 10 of the weight 9 in the center thereof, is integrally molded from a synthetic resin material. The inner lid fitting part 7 of the cylindrical peripheral wall part 3 is inserted into the inner lid 13, and the inner lid 13 is removably inserted into the hollow container body 4. through hole 1 of inner lid body 13 respectively.
A through hole 14, 14' having the same diameter as that of the packing 15, 15' is bored between the packings 15, 15' having an outer diameter slightly smaller than the recessed part 11, and a suitable mesh having approximately the same diameter as the packing 15, 15'. The flow rate adjustment net 16 is sandwiched in a sandwich-like manner and is inserted and removably inserted. A water passage hole 8 for the weight 9 is provided at the center of the bottom wall plate part 18, which has a circular packing restraint part 17 whose middle part protrudes upward.
A cap-shaped lid body 20 having a through hole 19 of approximately the same diameter as the hollow container body 4 is provided with a screw 21 on the inner circumferential surface of the side wall portion to be screwed into the screw 6 of the cylindrical peripheral wall portion 3 of the hollow container body 4.
The screws 6 and 21 are screwed together to form a packing holding base part 1.
7 to press the packings 15, 15' and the flow rate adjustment net 16 to the inner lid body 13,
The inner lid body 13 is pressed against the cylindrical peripheral wall portion 3, and the lid body 20 is detachably fixed to the hollow container body 4 to constitute the float-type chemical liquid underwater diffuser A of the present invention.

Operation Next, the operation of the present invention will be explained with reference to the usage conditions shown in FIGS. 3 to 5.

In the hollow container body 4 of the chemical solution underwater diffuser A of the present invention, an amount of the chemical solution D slightly smaller than the capacity of the container body 4 is placed.
(highly concentrated stock solution), the tip opening of the water passage hole 8 is covered with a flow rate adjustment network 16 of an appropriate mesh adapted to the set flow rate of the chemical solution D, and this diffuser A is connected to a waste solution storage tank. Alternatively, if it is poured into river wastewater W, the diffuser A will be inverted with the lid 20 facing downward due to the weight of the weight 9, as shown in FIG.
The inside becomes airtight, and the container body 4 is floated with the upper part exposed above the water surface WL by the buoyancy of the upper air layer P, and is held in place by the tethers 22, 22.

Diffuser A floating in wastewater W in the state shown in Figure 3
Due to the difference in concentration between the low-concentration wastewater W and the high-concentration chemical solution D, the chemical solution D in the container body 4 flows through the flow rate adjustment network 16
It gradually flows out and diffuses into the wastewater W through the
Due to the depressurization of the air layer P by the outflowing chemical solution D, the wastewater W enters the container body 4 through the flow rate adjustment network 16 and accumulates in the upper part.This action is gradually continued, and the wastewater is purified by the outflowing and diffused chemical solution. This operation is carried out for a long time, and when the concentration of the liquid inside the container body 4 and the liquid outside the container body 4 becomes uniform as shown in FIG. 5, this action stops. Repeat the operation.

As a result of experiments, the water purification work according to the present invention was conducted by using diffuser A containing 10 kg of drug stock solution (deodorizing liquid) as a reservoir.
When installed at a rate of one per ^100m2 , the effective period is approximately 4 weeks.

(Effects) When using the present invention to purify wastewater in wastewater reservoirs or rivers, one person or one person is required to put the chemical into the container, replenish the chemical, and install or collect the diffuser in the wastewater. It is extremely easy to work with, as it requires almost no labor or time other than two workers, and is economical, as compared to conventional methods, there is no waste in the amount of chemicals used. This is a device with excellent practical effects, such as having practical advantages and long-lasting water purification effects.
