Abstract

PROBLEM TO BE SOLVED: To provide a waste water treating device extremely compactly constituted by which kitchen waste water or the like is easily purified. SOLUTION: A waste water inflow port 3, and a treated water discharge port 4 and an oil discharge port 5 are formed in the upper part at one end of a treating tank 1 and in the upper part at the other end thereof, respectively. A filter 8 for removing solid matter of large size is internally installed below the waste water inflow port 3, and also, the required number of baffle plates 9 are alternately and internally installed so that filtered waste water of the filter 8 may be caused to meander in order in the up and down directions and flow in the direction of the treated water outflow port 4, and in the regions where the baffle plates 9 are internally installed, filters 10 for removing suspended matter are arranged under the liquid level.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wastewater treatment apparatus suitable for treating mainly small-scale kitchen wastewater.

[0002]

2. Description of the Related Art Conventionally, for the purpose of preserving water quality in public waters, wastewater discharged from factories and business establishments has been purified to the standards set forth in the Water Pollution Control Law and prefectural ordinances. Must be drained. Therefore, various treatment methods such as solid-liquid separation treatment, physicochemical treatment, biological treatment, and heat treatment are disclosed according to the type and content of the wastewater. However, on the other hand, a suitable treatment apparatus for small-scale kitchen wastewater has not yet been proposed.

[0003] In view of such circumstances, an object of the present invention is to provide an extremely compact wastewater treatment apparatus capable of easily purifying kitchen wastewater and the like.

[0004]

That is, according to the present invention, a wastewater inlet 3 is formed at one upper end of a treatment tank 1, and a treated water outlet 4 and an oil outlet 5 are formed at the upper end of the same. A filter 8 for removing coarse solids is provided below the inlet 3, and a required number of obstructions are provided so that the filtered wastewater of the filter 8 is meandered up and down sequentially and flows toward the treated water outlet 4. A wastewater treatment apparatus, wherein plates 9 are alternately provided, and a filter 10 for removing suspended matter is disposed below a liquid level in an internal portion of the baffle plate 9. It is assumed that.

In the wastewater treatment apparatus of the present invention, kitchen wastewater or the like flows from the wastewater inlet 3 into the treatment tank 1,
The coarse solids are separated and removed by the coarse solids removing filter -8, and the filtered wastewater is meandered up and down sequentially by the action of the baffle plate 9 to flow in the direction of the treated water outlet 4. Filter for removing suspended matter from suspended matter
10 to separate and remove the treated water from the treated water outlet 4 to the outside, and the floating oil to the oil outlet 5
It is one that discharges more outward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a relatively small processing tank with a lid 2 having a lid, 3 is a wastewater inlet formed at one upper end of the processing tank 1, and 4 and 5 are processing water outlets formed at the upper end of the same. The treated water outlet 4 is set to be below the liquid level, and the oil discharge port 5 is set to be at the liquid level. Reference numeral 6 denotes a wastewater inflow chamber defined by a partition bottom plate 7 and a baffle plate 9 to be described later in the treatment tank 1 so as to communicate with the wastewater inlet 3. The roughly bucket-shaped filter for removing large solids 9 then makes the filtered wastewater filtered by the filter for removing large solids 8 meander up and down sequentially and flows toward the treated water outlet 4. A required number of baffles 10 which are alternately and removably mounted in order to remove a required number of suspended matters which are removably and horizontally disposed at an internal portion of the baffle 9 so as to be located below the liquid level. In the filter, the suspended matter removing filter 10 is formed in a small mesh shape gradually toward the treated water outlet 4. Other, 11
Is a drainage port with a valve formed at the lower end of the processing tank 1 so that the processing water outlet 4 is located on the side.

Next, the operation of the embodiment configured as described above will be described. First, required wastewater, such as kitchen wastewater, flows into the wastewater inflow chamber 6 sequentially from the wastewater inlet 3, and is filtered by the filter 8 for removing coarse solids to separate and remove coarse solids from the wastewater. The waste water meanders up and down by the action of the baffle plate 9 and the treated water outlet 4 is made to flow. Then, the suspended solids in the wastewater are sequentially passed through the suspended solids removal filter 10 when flowing vertically, and the suspended solids in the wastewater are separated and removed. The oil is discharged to the outside, and the floating oil is discharged to the outside from the oil discharge port 5.
At this time, the treated water outlet 4 is located below the liquid level, and the oil outlet 5 is located at the liquid level.
The treated water and oil can be reliably separated and discharged to the outside. If the filter 8 for removing large solids or the filter 10 for removing suspended solids is clogged due to continuous use, it may be appropriately removed and cleaned.

[0008]

According to the present invention, as described above, the wastewater inlet 3 is formed at one upper end of the treatment tank 1, and the treated water outlet 4 and the oil outlet 5 are formed at the upper end of the same. A filter 8 for removing coarse solids is provided below the inlet 3, and a required number of obstructions are provided so that the filtered wastewater of the filter 8 is meandered up and down sequentially and flows toward the treated water outlet 4. Plates 9 are alternately provided, and a filter 10 for removing suspended matter is disposed below the liquid level in the internal portion of the baffle plate 9. It is allowed to flow into the treatment tank 1 to separate and remove coarse solids by the filter 8 for removing coarse solids, and the wastewater is sequentially meandered vertically by the action of the baffle plate 9 and flows toward the treated water outlet 4. To remove suspended matter in wastewater from wastewater The filter 10 separates and removes the treated water from the treated water outlet 4 to the outside, and the floating oil is discharged to the outside from the oil outlet 5 to reliably purify the required wastewater such as kitchen wastewater. You can do it. In addition, since it is compact and has a simple structure, not only can it be manufactured easily and inexpensively, but also it can be installed in a small space, and as a result, small kitchen wastewater It can be suitably used for processing and the like.
