Conventional wastewater purification was performed by passing the wastewater through a filtration and filtering member having a porous structure, but the purification method using such a filtration and filtering method reduces the purification ability when the pores on the filtration and filtering member are large, and the pores on the filtration and filtering member are small. In this case, there is a problem in that the filtration filter must be frequently replaced because the pores are easily clogged by foreign substances such as sludge in wastewater.

Accordingly, in the present invention, the problem of the conventional wastewater purification apparatus is solved by purifying wastewater by a precipitation method using a chemical coagulant that aggregates foreign substances such as sludge.

At this time, coarse foreign matter having a certain size or more may be transported together by the force of sucking the wastewater, and foreign matter having a certain size or more transported together with the wastewater blocks the hole of the filtration filter 101B of the filtration tank 100B. Since it acts as a cause of reducing the use period of the filtration filter 101B, the sludge blocking unit 111 is formed on the supernatant water transfer unit 110 to prevent coarse foreign matter particles from being transferred together.

At this time, the sludge blocking unit 111 may be coupled to either side of the longitudinal direction of the wastewater transfer unit 110 and the other side, a space into which wastewater is introduced is formed, and a space formed inside the body surface and A plurality of pores communicating with the outside may be formed, and foreign matters larger than the diameter of the pores may be filtered and filtered while the wastewater introduced through the pores is introduced into the space formed therein.
