If the purified wastewater is discharged into rivers, it prevents contamination of soil and groundwater, as well as the natural environment. Will reduce the destruction of.

That is, in the related art, wastewater such as sewage, sewage, manure and waste leachate is first removed from the residue by a residue treatment apparatus, and the wastewater from which the residue is removed is purified by a wastewater treatment apparatus and discharged to the stream.

Conventional wastewater treatment apparatus, as shown in Figure 2, by forming a plurality of diaphragm (100a) in one main body 100, by the flow rate adjustment tank 101, the waste water from which the residue is removed, by the aerated air A plurality of aeration tanks 102 for activating microorganisms, and the inverted cone-shaped sedimentation sludge collection unit 103a are built in to form a sedimentation tank 103 for sedimenting sludge, and the treated water flowing out of the sedimentation tank 103 is formed. The disinfection tank 104 or the like is discharged to the outside.

And conventionally provided with an diffuser 105 for injecting air in the inner lower portion of the aeration tank 102 to supply air to the aeration tank 102, the inside of the aeration tank 102, while the microorganisms adhere to the waste water Microbial contact media 106 is installed to oxidatively decompose and cleanse it.

The microbial contact medium 106 is to treat wastewater with appropriate biochemical oxygen demand and chemical oxygen demand, and the specific surface area should be large and attached to a large number of microorganisms attached to it, and should be resistant to appropriate desorption and load fluctuations or impacts. It must be suitable for biological wastewater treatment.

Thus, conventionally, the waste water is purified through the flow rate adjusting tank 101, the plurality of aeration tanks 102, and the settling tank 103 in turn, and the settling sludge is re-injected from the settling tank 103 into the flow adjusting tank 101 and purified. The treated water is overflowed to the disinfection tank 104 to be discharged to the outside.

At this time, the waste water is purified by the microorganisms attached to the microorganism contact medium 106 as well as contact with the oxygen in the settling tank (103).

However, conventionally, since the air supplied by the diffuser installed in the aeration tank is directly supplied to the microbial contact media, a large amount of air may contact the microbial contact media, so that the microbial contact media may swing due to the momentum of the air. In addition, sludge attached to the microorganism contact medium may be detached to a size smaller than an appropriate size, and thus, the viability of the microorganisms is lowered, thereby degrading the purification capacity of the wastewater.

In addition, conventionally, since the air injected into the diffuser immediately rises, there is a disadvantage in that the residence time of the air staying in the wastewater in the aeration tank is insufficient and thus the wastewater purification treatment capacity is lowered.

The present invention is devised to solve the problems of the prior art as described above, an object of the present invention is to disperse the air sprayed from the bottom of the microbial contact medium to supply the microorganism contact media to facilitate the viability of the microorganisms of the microbial contact media The present invention provides an aeration air dispersing device for a wastewater treatment device that can be easily strengthened and increase the air residence time to easily purify the wastewater.

In order to realize this, the present invention has a plurality of aeration tanks which are sequentially installed from the bottom of the diffuser and the microbial contact medium for decomposing the waste water from the bottom, the waste water purification device comprising a waste water purification apparatus comprising a waste water and air A medial built-in member formed of a material for distributing the wastewater is installed below the microbial contact media, and a plurality of media in which microorganisms adhere and survive is embedded in the medial built-in member to disperse the air injected from the diffuser. Provides aeration air dispersing device.
