Description

Continuous influent apparatus and decanting apparatus for cleaned water layer of sewage and wastewater}

The present invention relates to a device for adhering biochemical decomposition by microorganisms and symbolic water after precipitation in a continuous batch reactor, which is one of the methods used in sewage treatment plant, sewage treatment plant or wastewater treatment plant. The present invention relates to a continuous inflow of sewage and wastewater and a symbolic water advection treatment device to float the symbolic water of a certain layer, which is floating and has no inflow of scum.

The technology to which the present invention belongs is largely divided into a mechanical advection device and a floating advection device.

When the mechanical advection device is installed at the upper part of the continuous batch reactor and operated by power and reaches the advection step, the debris is discharged as it descends to the water surface, and the waste is discharged as it is. Since the size of the advection device is large, the installation cost and power cost are excessively increased. There was a problem.

In addition, in the case of the floating airflow device, the opening and closing of the airflow tube by an electric valve and a solenoid valve, and the opening and closing is repeated one year (approximately 4 to 6 times a day), resulting in electric malfunction and electric transmission due to wear of the sealing part. Since the opening and closing of the valve and the solenoid valve is poor, there is a problem in that the high concentration of sludge and undissolved influent flows out of the continuous batch reactor.

There is no device that prevents the pump from falling down the sludge layer during the advection after sedimentation.Therefore, the sludge flows out of the continuous batch reactor to deteriorate the water quality due to the malfunction or failure of the water level detector. Had problems.

In addition, the influent continuous inflow device is required to reduce the rate of rise of the influent continuously introduced in a continuous batch reactor in which the influent is continuously introduced so that precipitation is not disturbed.

In other words, the influent should be concentrated in one part, and the rising speed will be larger than the settling speed in that part, and the discharge water quality should be prevented from deteriorating.

Therefore, the present invention was devised to solve the above problems, without using a mechanical power device or an electrical device, by moving the advection device up and down in a floating state on the water surface in response to the fluctuation of symbol water level, It is aimed to provide only the symbolic water, and also to provide the most economical, simple installation and easy maintenance and continuous inflow of sewage and wastewater and symbolic water advection treatment device.

In addition, the present invention devised to solve the above problems is to provide a continuous inflow of sewage and wastewater and supernatant water advection treatment apparatus does not affect the sedimentation by reducing the rising rate of the influent stably.

As shown in Fig. 1, reference numeral 20 denotes a continuous batch reactor.

The reactor 20 is provided with a floatation float 30 floating on the surface of the symbolic water of the sewage and wastewater introduced into the reactor.

The air floatation body 30 is provided with a float 32 used as a polyurethane foam or styrofoam on the upper portion, and an airflow chamber 34 for adhering the symbolic water to the lower portion of the float, and an airflow chamber 34. At least one symbol water inlet (34a) for introducing the symbol water to the inlet and conical symbol water outlet 34b for extracting the symbol water introduced into the advection chamber (34).

The advection chamber 34 may be configured in one of circular, square, and semicircular cross sections.

That is, the advection chamber 34 may be composed of a circular or square pipe or a semi-circular pipe, as shown in FIGS. 5A, 5B and 6A, 6B, and the material may be made of stainless steel or PVC of watertightness and corrosion resistance. It is made of synthetic resin.

The body of the floatation body 30 is made of synthetic resin such as metal or PVC, and when made of metal, the float 32 has a volume capable of floating the entire floatation body 30. At this time, the shape of the float 32 is preferably configured in a circular shape that can maintain a good balance even in the swing at the time of abandonment.

Hinge ring (37) may be installed on the upper surface of the airflow float (30) for convenience of lifting.

To the symbolic water outlet 34b of the advection floating body 30 is connected via a stretchable bellows and a secondary flow pipe 41, and an advection pump 40 for generating a symbolic water suction force to the outlet 34b is connected. The airflow pump 40 is configured to be on / off by sensing means for detecting the position of the airflow floatation body 30 (not shown). At this time, the material of the adduct pipe 41 may be made of corrosion-resistant stainless steel or synthetic resin.

The bellows is a bellows 42 that can be freely stretched up and down, and has a reinforcing circular ring 43 for supporting the bellows when the aeration pump 40 is suctioned, and both ends of the bellows 42 are provided with outlets of the floats 30. 34b) It is fixed to the neck part and the advection pipe 41 by the band 44.

At this time, the material of the bellows 42 is preferably a special synthetic rubber such as EPDM resistant to watertightness, chemical resistance, wear resistance and heat resistance, and the circular ring 43 and the band 44 may be made of, for example, stainless steel.

Therefore, even if the position of the advection pump 40 is fixed, the advection float 30 can be moved up and down according to the surface height of the symbolic water due to the flexible elasticity of the elastic bellows 42.

A spring-supported valve 54 is provided at the symbolic water inlet 34a of the airflow floatation body 30.

The spring-supported valve 54 is supported by a spring 52 force on the side of the symbolic water inlet 34a to close the symbolic water inlet 34a, and is driven by a suction force during the driving of the advection pump 40. 52) It overcomes the force and serves to open the symbolic water inlet (34a).

At the lower end of the spring-loaded valve 54, a watertight rubber 55 is attached to prevent the inflow of the suspension during the aeration (process of blowing oxygen) in the reaction tank 20.

The spring-loaded valve 54 quickly blocks the inflow of the suspension upon abandonment by the elastic restoring force inherent to the spring 52, and is attached to the lower portion of the airflow chamber 34 to be positioned below the water surface, Shut off the inflow.

As the material of the spring 52, for example, stainless steel resistant to corrosion resistance is used, and the watertight rubber 55 preferably uses special synthetic rubber such as EPDM that is strong in watertightness, chemical resistance, abrasion resistance, and heat resistance.

The advection floatation body 30 is moved up and down by a pair of guide rods 62 in the continuous batch reactor according to the surface height of the symbolic water.

The guide rod 62 is installed in parallel to the bottom of the continuous batch reactor 20 to suppress the shaking of the adjuvant floating body 30 caused by the shaking of the suspension when the continuous batch reactor 21 is abandoned. The guide rod 62 is in contact with the guide roller 36 rotatably installed on the roller hinge 31 of the airflow floatation body 30.

As the material of the guide roller 36, for example, a special engineering plastic having good abrasion resistance is used, and the guide rod 62 may be made of stainless steel resistant to corrosion.

And the guide rod 62 is provided with an upper stopper (63a) for preventing the departure to the top for the purpose of limiting the height according to the movement of the float floating body 30, the flow pipe 41 is settled The lower stopper 63b for preventing the lower part detachment of the airflow floatation body 30 to a sludge layer is provided.

At the bottom of the continuous batch reactor 20, a hollow pipe 70 having a plurality of outlets 72 formed upward as shown in FIGS. The rising speed reduction induction cover 80 for switching the upward direction of the inflow water flowing out from the discharge port 72 in the downward direction above the oil hole pipe 70 is disposed.

The rising speed reduction induction cover 80 is discharged to the outlet 72 of the perforated pipe 70 to reduce the rising speed of the influent by changing the direction of the inflow rising upward once.

Therefore, the cross section of the rising speed reduction induction cover 80 applied to the present invention may be configured as a hatshade or a semi-circle not shown as shown in FIG.

The material of the perforated pipe 70 and the rising speed reduction induction cover 80 may be a synthetic resin such as stainless steel or PVC.

The operation of the continuous flow of sewage and wastewater and the advection treatment system for symbolic water will be explained.

First, when the precipitation, which is one of the treatment steps of the continuous batch reactor 20, is completed, solid-liquid separation is formed so that the clear supernatant layer 100 is formed at the top, and the precipitate sludge layer 200 is formed at the bottom.

When the advection floatation 30 of the two-pronged line reaches the highest water level 2, the advection pump 40 is driven by the sensing means not shown.

A suction force is generated at the symbol water outlet 34b by the driving of the flow pump 40, and the spring-supported valve 54 blocking the symbolic water inlet 34a on the side of the airflow chamber 34 applies the force of the spring 52. Win and rise to open the symbolic water inlet (34a).

Therefore, the symbol water of the symbol water layer 100 passes through the advection chamber 34 through the symbol water inlet 34a and exits to the symbol water outlet 34b and is discharged to the advection pump 40.

In this way, when the water level of the symbolic water layer 100 gradually decreases, the position of the adjuvant floating body 30 reaches the minimum water level 3 by the expansion and contraction of the bellows 42. As such, the adjuvant floating body 30 fluctuates downward, and the clear symbol water is adsorbed to the outside of the continuous batch reactor 20.

By the sensing means not shown at the lowest water level 3, the operation of the advection pump 40 is stopped and the suction force of the advection pump 40 is dissipated so that the spring-supported valve 54 can be quickly and accurately by the restoring force inherent in the spring 52. By closing the supernatant water inlet 34a, the inflow of the suspension is blocked when giving up.

In addition, the sewage and wastewater continuously introduced into the continuous batch reactor 20 according to the present invention is introduced into the hole tube 70 disposed at the bottom of the continuous batch reactor 20 to a plurality of outlets 72 formed above. Discharged. The discharged inflow water rises upwards and then collides with the bottom surface of the rising speed reduction guide cover 80, and the direction thereof changes downward to decrease the flow velocity.

Therefore, the rising speed reduction guide cover 80 reduces the rising speed of the influent, thereby reducing the suspension.

As described above, according to the present invention, the float is floating on the surface with no power and moves up and down according to the fluctuation of the water level, thereby reducing the power cost, and using the spring rather than using the self-weight, which is a conventional valve opening / closing method, inherent spring It closes quickly by the restoring force of and excellent water tightness completely blocks the inflow of suspension. In addition, the vertical and vertical movement by the bellows, rather than the vertical movement by the hose, the structure is simplified, and the maintenance is convenient. In addition, by sucking and adhering the symbolic water below the surface of the water, the inflow of debris is blocked at the source, and only the clear symbolic water is adsorbed.

On the other hand, according to the present invention, the continuous inlet device has an effect to effectively reduce the rate of rise so that the inflow water continuously into the continuous batch reactor without adversely affecting precipitation and advection water quality.
