The waste water treatment device 100 of the present invention is installed at a common waste water generation site, and is used to more reliably perform the second water treatment required for the purification treatment of the first treated waste water.

For this reason, the wastewater treatment apparatus 100 is connected to the wastewater storage tank 10 that collects the first-processed wastewater through the wastewater inflow pipe 20, and is connected to an external storage tank (not shown) through the wastewater discharge pipe 30.

The waste water treatment apparatus 100 can efficiently remove the oil and foreign substances in the waste water by discharging the waste water in the treatment tank to the outside while passing through a plurality of filter members by means of vacuum negative pressure as a negative pressure.

In FIG. 2, the constituent elements inside the wastewater treatment apparatus 100 are illustrated, and they are generally composed of a housing 102, a filter member 110, a filter space portion F, a bypass space portion S, and a vacuum pump P.

The casing 102 constituting the main body of the wastewater treatment apparatus 100 is generally constituted by a concrete storage facility, but it may be constituted by an iron structure or a synthetic resin tank, etc., according to the amount of wastewater to be treated separately. In the interior of the housing 102, in order to allow a proper amount of waste water to flow and be treated to form a temporary storage space, a transfer device or structure may be applied so as to move the waste water at an appropriate speed without stagnation.

The internal space of the housing 102 is roughly divided into a filter space portion F and a detour space portion S that is divided in the longitudinal direction with respect to both sides of the filter space portion F. Among them, the filter space part F means a space for filtering by means of a filter member, and the detour space part S, as described later, means that when one filter member among a plurality of filter members is clogged, the wastewater is detoured to the next At another filtering member while performing filtering space.

Preferably, the filter space portion F is partitioned by a plurality of filter members 110 for separating and removing grease and foreign substances contained in the waste water.

The plurality of filter members 110 are installed at predetermined intervals so as to be inserted into the installation guide 106, and the installation guide 106 is formed on the partition wall 104 that separates the filter space F and the bypass space S.

The plurality of filter members 110 are composed of a net 111 for removing foreign substances in waste water, and a frame 113 for fixing and maintaining the net 111. Among them, the net 111 may be formed of various materials such as non-woven fabric, PE material, and metal material, and the size of the net 111 may be configured so that the size of passing particles is reduced in stages.

Especially at the lower part of the plurality of filter members 110, at least one wheel part 115 is provided. The wheel portion 115 supports the filter member 110 so that it can move forward, backward, left, and right. As described above, the filter member 110 can move forward, backward, left, and right by means of the wheel portion 115, so that the problem of clogging of the net 111 by foreign substances attached to the filter member 110 can be prevented in advance.

In this embodiment, the case where there is one wheel part 115 is taken as an example, but of course, it may be two or more if necessary.

When the one of the plurality of filter members 110 is clogged, the detour space portion S detours the waste water to another filter member located next to perform filtration.

As shown in FIG. 4, for example, when all of the first to third filter members are clogged, the detour space portion S detours the waste water to the fourth filter member located at the fourth place to be filtered by the fourth filter member.

The detour space portion S is divided into a plurality of spaces by the partition wall 104 that distinguishes the filter space portion F from the detour space portion S, and the cutoff wall 120 that is formed perpendicularly to the partition wall 104 in the longitudinal direction.

The detour space portion S includes: an inflow portion 124 formed on the upper side so that the detour wastewater flows into the detour space portion S; and an outflow portion 126 formed on the lower side so that the detour wastewater flows out into the filter space portion F. Among them, the inflow portion 124 is mainly formed on the partition wall 120. However, it may happen that the first filter member located at the front is clogged. In this case, an exception may be formed on the upper side of the cut wall 120 (see FIG. 3 ).

As shown in FIG. 5, the inflow portion 124 and the outflow portion 126 may be provided with a rotation opening and closing plate 122a and a stopper 122b, respectively.

The rotation opening/closing plate 122a is opened and closed with the flow of waste water around the rotation axis, and the stopper 122b limits the rotation range of the rotation opening/closing plate 122a. Preferably, the position-limiting portion 122b allows the rotary opening and closing plate 122a to open and close in one direction, thereby preventing backflow of waste water.

The vacuum pump P is connected to the discharge port of the casing 102, that is, to the waste water discharge pipe 20, and generates a vacuum negative pressure as a negative pressure, so that the waste water in the casing 102 is discharged to the outside while passing through the plurality of filter members 110. Efficiently remove grease and foreign substances in wastewater.

Preferably, a vacuum pressure (negative pressure) is periodically generated in the vacuum pump P, and negative pressure is generated while attracting the waste water in the housing 102. At this time, the waste water can be removed while passing through the plurality of filter members 110. substance.

A display unit (not shown) capable of displaying a control screen for controlling the vacuum pump P may be added. On the screen of the display unit, for example, a user interface that displays the operation and usage information such as the driving and stopping of the vacuum pump P and setting the vacuum pressure in real time can be provided.

In addition, a stirring device 114 is installed inside the housing 102. The stirring device 114 may be one, but for efficient separation, it may be preferable to install a plurality of them. The stirring device 114 may be additionally installed between each separation device one by one.

As shown in FIGS. 7 and 8, the stirring device 114 is a device that causes vibration or rotation and transmits a force to wastewater by means of an electric motor, an air cylinder, a hydraulic cylinder, or other driving devices.

The stirring device 114 includes: a driving portion 114a that generates a kinetic force using the force of electricity or air, oil, etc.; a cylinder 114b, which transmits the kinetic force of the driving portion 114a; a contact portion 114c, which rotates by the kinetic force transmitted by the cylinder 114b Or vibrate or reciprocate and stir the wastewater.

In the drawings of the present invention, a case where a plurality of comb teeth are formed side by side like a comb in the contact portion 114c can be formed in various shapes such as a circular plate, a spiral, or a flat plate. Preferably, it is made of a plate-shaped comb-tooth structure or a spiral-shaped rotating body, etc., so that the area in contact with wastewater can be maximized.

As shown in FIG. 9, the stirring device 114 provides vibration by (a) reciprocating motion by means of the cylinder 114b, or (b) rotating by reciprocating motion by rotation of the cylinder 114b, or (c) reciprocating left and right by the cylinder 114b And provide methods such as impact to stir the wastewater.
