Hereinafter will be described in detail with reference to the accompanying drawings a specific technical configuration and operation that can effectively achieve the object of the present invention as a preferred embodiment.

5 and 6 are side cross-sectional views and a plan view of the wastewater treatment apparatus according to the present invention, in which the water flow distribution panel and the sedimentation induction pipe are installed inside the wastewater treatment tank 100. , Waste water treatment apparatus is already known by the prior art documents that the applicant has been pre-registered.

The present invention forms the wastewater treatment tank 100 in a multiple structure of the front sedimentation chamber 110 and the rear sedimentation chamber 120, but the front sedimentation chamber 110 into which the wastewater flows in through the inlet 101. The water flow distribution panel 130 in which a plurality of holes 131 are formed is provided individually or in plurality, and in the rear sedimentation chamber 120, a plurality of inclined plates 171 are obliquely overlapped to overlap the precipitation induction pipe 140. It is characterized by the installation.

That is, in the front sedimentation chamber 110, the water flow is evenly distributed up, down, left, and right by the water dispersion panel 130, and in the rear sedimentation chamber 120, sludge of the water dispersed by the sedimentation induction pipe 140 is effectively It was settled.

Here, the funnel-shaped sludge collecting parts 111 and 121 are formed at the lower portions of the front sedimentation chamber 110 and the rear sedimentation chamber 120, and the collected sludge is external to the bottom of the sludge collecting parts 111 and 121. Transfer screw 112, 122 to discharge to the is installed.

The inclined plate 141 constituting the precipitation induction pipe 140 is configured in a wave shape in order to increase the contact surface area.

The inner rear of the rear sedimentation chamber 120 is provided with a water level control tank 150 partitioned to include an outlet 102, the top of the side wall 151 of the water level control tank 150 to the elevating control rod 154 The water level control plate 153 is installed to adjust the height of the hanging is adjusted water level.

In addition, the bottom 152 of the water level control tank 150 is installed through a plurality of water flow control pipe 156 opened and closed by the valve 155, the water flow in the rear settling chamber 120 is the water level control tank 150 It is configured to be discharged to the outlet 102 after flowing upwardly into the interior.

The present invention formed as described above is to increase the efficiency of the sedimentation when the foreign matter contained in the waste water introduced into the wastewater treatment tank 100 is purified by floating and sedimentation due to the specific gravity difference.

That is, since the wastewater introduced into the front sedimentation chamber 110 through the inlet 101 passes through a plurality of holes 131 while colliding with the water dispersion panel 130, the wastewater flows evenly up, down, left, and right, and the water flows. While colliding with the dispersion panel 130 and passing through the plurality of holes 131, fine bubbles are generated in the front precipitation chamber 110 in a large amount.

In addition, foreign matters in the water flow introduced into the front sedimentation chamber 110 are floated or settled due to the specific gravity difference, wherein the bubbles generated as described above are attached to the oil or microorganism sludge or suspended solids, thereby reducing the specific gravity than the water. B. Microbial sludge and suspended solids are easily floated on the surface of the water, making it easy to separate and remove them.

Here, the front sedimentation chamber 110 may use the buoyancy of the air, so the sludge sedimentation rate may be very slow, but it is possible to remove floating foreign matters in a faster time.

In addition, foreign matters having a high specific gravity are collected and collected in the funnel-type sludge collecting part 111 provided in the lower portion of the front sedimentation chamber 110 using the buoyancy of air. As it is discharged to, the front settling chamber 110 serves to first filter the foreign matter that is likely to float and large foreign matter first.

Here, as shown in FIG. 5, two or more water flow dispersion panels 130 may be installed in the front sedimentation chamber 110. At this time, the rearmost water flow distribution panel 130 is installed on the boundary (B) line of the front sedimentation chamber 110 and the rear sedimentation chamber 120 where the two funnel-type sludge collecting portions 111 and 121 meet each other. The front sedimentation chamber 110 and the rear sedimentation chamber 120 are separated from each other by the water flow distribution panel 130 installed at the boundary portion (B).

Then, foreign matters that do not pass through the holes 131 of the water dispersion panel 130 are mostly lifted or settled and removed in the front sedimentation chamber 110, and are passed through the holes 131 of the water dispersion panel 130. Only small floats or sediments are introduced into the rear sedimentation chamber 120 together with the wastewater and wastewater.

The wastewater introduced into the rear sedimentation chamber 120 immediately passes through the sedimentation induction pipe 140 in which a plurality of inclined plates 141 are inclined obliquely downward. That is, the inclined plate 141 having a wave cross section controls the speed of the water flowing through the waste water by increasing the surface area in contact with the waste water.

Figure 9 is a partially enlarged cross-sectional view of the water flow control plate installed in the wastewater treatment apparatus of the present invention. As shown in the rear sedimentation chamber 120, a plurality of water flow passages 161 and 162 staggered with each other on the front and rear surfaces may be installed behind the sedimentation induction tube 140. have.

The water flow control plate 160 serves to slow the flow of wastewater of the wastewater, which is passed by the water flow passages 161 and 162 formed by staggering each other on the front and rear surfaces, as slowly as possible.

In addition, since the wastewater passed along between the inclined plates 141 in the rear settling chamber 120 includes only sludge foreign matter having a small size passing through the hole 131 of the water dispersion panel 130, Likewise, the slower the flow rate, the higher the sludge settling efficiency.

The sludge debris precipitated in the rear sedimentation chamber 120 is collected in a separate sludge collecting portion 121 that is isolated from the sludge collecting portion 111 of the front sedimentation chamber 110 to the outside by the transfer screw 122. It is discharged, it is possible to adjust the amount distribution and the discharge concentration of the sludge sedimented in the front sedimentation chamber 110 and the rear sedimentation chamber 120, respectively, so that the sludge treatment efficiency can be improved and the sludge disposal can be more easily performed. .

When the water flow guided downward along the inclined plate 141 of the precipitation guide passage 140 reaches the bottom of the water level control tank 150, the sludge foreign matter precipitated below the water level control tank 150. Moved upward through the pipe 156 is introduced into the water level control tank 150 of the upper and discharged through the outlet 102.

Here, by operating the valve 155 of the water flow control pipe 156, it is possible to finely control the amount of water flowing into the water level control tank 150, it is possible to control the water flow pressure and the flow rate.

That is, when the amount of water flowing into the front settling chamber 110 through the inlet 101 is less or less than the quantity discharged through the outlet 102, the water level in the front settling chamber 110 and the rear settling chamber 120 is increased. As the change occurs, the shroud pressure and water flow rate change.

According to the present invention, the internal volume is appropriately varied by raising or lowering the level control plate 153 installed on one side of the side wall 151 by loosening or tightening the elevating adjustment bar 154 according to the water level which is changed frequently, and the water flow control tube 156. By simply adjusting the amount of water passing through the water level can be easily adjusted according to the changing water level from time to time.

8 is a side view showing another embodiment of the present invention, as shown in the front sedimentation chamber 110 of the present invention may be installed with the sedimentation induction passage 170 together with the water flow distribution panel 130.

In this case, the settling induction pipe 170 installed in the front settling chamber 110 is spaced between the inclined plates 141 of the settling induction pipe 140 installed in the rear settling chamber 120 at intervals of the plurality of inclined plates 171. It is characterized by a wider arrangement.

That is, in the case of the front sedimentation chamber 110, since it is a place for removing the bulky floating matter or the specific gravity sediment foreign matters, the interval between the inclined plates 171 of the sedimentation induction passage 170 is settled in the sedimentation passage of the rear sedimentation chamber 120. If it is narrowed like the inclined plate 141 of 140, it may be easily blocked by suspended matter or settled foreign matters, and may cause the flow of waste water to be disturbed.

Therefore, the precipitation induction pipe 170 installed in the front sedimentation chamber 110 is preferably disposed to have a wider inclination plate spacing than the precipitation induction pipe 140 installed in the rear sedimentation chamber 120.
