Figure 5 is a partial enlarged view of the domestic wastewater treatment machine of the above preferred embodiment of the present invention, showing that the pumping pump stops operating and the wastewater is returned to the wastewater tank.

In order to explain the present invention more clearly, the preferred embodiment is described in detail with reference to the accompanying drawings. FIG. 1 is a preferred embodiment of a household waste water treatment machine 100 for household use. The waste water is recovered or discharged after treatment, and comprises a barrel 10, a filter plate 20 and an activated carbon layer 30.

The tub 10 has a water inlet 12 and a water outlet 14 connected to each other, wherein the water inlet 12 is located at the bottom of the barrel 10, and the water outlet 14 is located at the top of the barrel 10. The domestic wastewater to be filtered is flowed into the tub 10 from the water inlet 12 and discharged from the water outlet 14.

In the present embodiment, the barrel 10 has a stop portion 101 which is an annular platform formed by the barrel body 10 at a predetermined height and contracted to a predetermined width (refer to FIG. 2). Therefore, the block portion 101 is formed. The barrel diameter between the bottom of the barrel 10 and the bottom of the barrel 10 is smaller than the barrel diameter between the block 101 and the top of the barrel 10. In addition, the barrel 101 of the barrel 10 is tapered toward the water inlet 12 from the bottom of the barrel 10, and has an arc shape from the outer side. The blocking portion 101 is configured to support the filter plate 20 such that a space 10a is formed between the filter plate 20 and the water inlet 12 of the tub 10, and the space 10a serves as a particulate deposit.

The filter plate 20 is a disk body made of polypropylene material, and has an upper surface 201 and a lower surface 202, the diameter of which is equal to the diameter of the barrel above the blocking portion 101 (refer to FIG. 3), and has a plurality of a sieve hole 20a, the aperture of the sieve hole 20a is tapered from the lower surface 202 of the filter plate 20 to the upper surface 201 of the filter plate 20 (refer to FIG. 4), in detail, close to the lower The opening 20a of the surface 202 has a pore diameter of about 50 to 100 μm, and the opening 20a of the upper surface 201 has a pore diameter of about 5 to 10 μm; The distribution of the mesh holes 20a is loosely to tightly arranged from the lower surface 202 to the upper surface 201 to form a filter structure having a progressive filtering effect.

The activated carbon layer 30 is disposed above the filter plate 20. The activated carbon layer 30 comprises a carbonized material 32 and a mesh bag 34. The carbonized material 32 is made of wood, residual wood chips, coconut shell, coal or asphalt at a high temperature. After carbonization by carbonization, the non-carbon component in the raw material is removed to form a porous carbide. Subsequent activation with hot air, water vapor or chemicals is required to cause a large amount of cracking and oxidation of the surface of the carbide to increase the adsorption surface area and chemisorption capacity.

In a preferred embodiment, the carbonized material 32 is granulated activated carbon for adsorbing organic matter in the wastewater and reducing chemical oxygen demand (COD), anionic surfactant, and grease. Of course, the carbonized material 32 can also be in other forms, such as a compacted activated carbon powder.

The mesh bag 34 is used to fill the above-mentioned carbonized material 32, which can be reused and facilitates replacement of the carbonized material 32. When the adsorptivity of the carbonized material 32 is weakened, the carbonized material 32 can be taken out from the net bag 34, and the carbonized material 32 can be passed into a high-pressure water vapor, and then heated to 400 ° C under a certain amount of oxygen concentration, that is, The adsorbed material on the surface of the carbonized material 32 can be removed to obtain a regenerated activated carbon. The regenerated and highly adsorbed carbonized material 32 is returned to the net bag 34 and placed in the barrel 10 again to allow the domestic wastewater treatment machine 100 to continue filtration purification.

The household wastewater treatment machine 100 of the above preferred embodiment performs three steps of purifying water in a single barrel: (1) separating and separating residual particles in the wastewater by using the space 10a in the barrel 10; (2) using the filter plate 20 The mesh 20a in the filter is suspended solids; and (3) activated carbon is adsorbed. Compared with the wastewater treatment system with many barrels in the past, it greatly reduces the occupied volume and meets the actual needs of the average household. Furthermore, replacing the traditional one with the filter plate 20 Conventional quartz sand filters suspended solids and also reduces manufacturing costs.

In addition, the preferred embodiment further includes a connecting tube 40 and an occluding member 60. The connecting tube 40 is located outside the barrel 10. The connecting end of the connecting tube 40 is connected to the water inlet 12 of the barrel 10, and the other end is connected to a first branch tube 42 and a second branch tube 44. The first branch pipe 42 extends outward from the connecting portion of the three pipes into a waste water tank 70, and a pumping pump 50 is connected to the end; the second branch pipe 44 also extends outward from the connecting portion of the three pipes. Inside the wastewater tank 70, an opening is formed at the end.

The occlusion member 60 is a ball body disposed at a connecting portion of the connecting pipe 40 and the first branch pipe 42 and the second branch pipe 44. The diameter of the occluding member 60 is larger than the diameter of the three pipe body, so The connecting portion of the three tubes is free to move but does not enter the inside of the three tubes. The movement of the occlusion member 60 can control the connection tube 40 to communicate with the first branch tube 42 or with the second branch tube 44, that is, when the occlusion member 60 blocks one end of the second branch tube 44. The connecting pipe 40 communicates with the first branch pipe 42. When the blocking member 60 blocks one end of the first branch pipe 42, the connecting pipe 40 communicates with the second branch pipe 44.

The actual operation of the domestic wastewater treatment machine 100 of the preferred embodiment of the present invention is shown in FIG. 1. The domestic wastewater will flow to the wastewater tank 70 for preliminary precipitation purification. The number of tanks and purification functions of the wastewater tank 70 are different depending on the type. There is a difference, and as an example, the waste water tank 70 has four separation grooves. The domestic sewage is first discharged to the first separation tank 70a, and the sludge or the larger impurities in the wastewater are precipitated and separated by preliminary sedimentation, and then discharged to the second separation tank 70b, and the oil density is less than the water density. The oil and water are separated, and the water from which the oil is removed is continuously discharged to the third separation tank 70c for precipitation separation of residual impurities, and finally the water flowing into the fourth separation tank 70d is clean water after the preliminary precipitation purification is completed.

The pumping pump 50 at the end of the first branch pipe 42 is located at the waste The fourth dividing groove 70d of the water tank 70 is used to draw the waste water in the fourth dividing groove 70d into the barrel 10 through the first branch pipe 42 and the connecting pipe 40. When the wastewater enters the connecting pipe 40 via the first branch pipe 42, the occlusion member 60 is subjected to the thrust generated by the gravity of the gravity and the flow of the waste water, blocking one end of the second branch pipe 44, so that the wastewater can directly enter the barrel. Filtration treatment is performed in the body 10.

During the process of the waste water flowing from the water inlet 12 of the barrel 10 to the water outlet 14, the suspended solids in the water are first removed through the filter plate 20, and the suspended solids blocked by the filter plate 20 are Partially dropped and deposited in the space 10a; and the water passing through the filter plate 20 is again permeable to the adsorption of the activated carbon layer 30 to a standard for recoverable and discharge, and finally discharged through the water outlet 14 of the barrel 10.

The flow direction of the wastewater in the barrel 10 is from bottom to top, opposite to the direction of gravity, thereby slowing the movement of water and prolonging the residence time of the wastewater in the filter plate 20 and the activated carbon layer 30, For optimal filtration and adsorption.

On the other hand, when the pumping pump 50 stops operating, the wastewater of the wastewater tank 70 no longer enters the barrel 10, and at this time, the wastewater discharged from the water outlet 14 in the barrel 10 is caused by gravity. The flow flows downward and finally flows out of the connecting pipe 40. As shown in FIG. 5, the water flowing downward from the connecting pipe 40 pushes the blocking member 60 when flowing to the connecting portion of the connecting pipe 40 and the first branch pipe 42 and the second branch pipe 44. The occlusion member 60 is moved to the right and falls into a socket 46 to no longer block one end of the second branch tube 44, so that waste water can flow from the connecting tube 40 into the second branch tube 44.

In addition, the occlusion member 60 can also be a floating body having a density smaller than water, so that when the amount of waste water flowing down from the connecting pipe 40 is large enough, the occluding member 60 can be floated and block one end of the first branch pipe 42. (shown by the imaginary line in Fig. 5), thereby allowing wastewater to flow from the connecting pipe 40 into the second branch pipe. 44. Since the other end of the second branch pipe 44 is located in the first dividing groove 70a in the wastewater tank 70, the wastewater discharged from the bottom of the barrel 10 without being processed by the domestic wastewater treatment machine 100 will be returned to the wastewater. The wastewater tank 70 performs a second precipitation purification.

In addition, at this time, the waste water that has not been discharged from the water outlet 14 in the barrel 10 may be partially suspended solids blocked by the filter plate 20 during the flow to the water inlet 12 due to gravity. The downward movement is carried out, and the suspended solids are returned to the wastewater tank 70 to achieve the effect of washing the filter plate 20.

The design of the connecting pipe 40, the pumping pump 50 and the occluding member 60 outside the barrel 10 can smoothly bring the waste water in the waste water tank 70 into the barrel 10 for filtration and purification, and ensure that the The wastewater that meets the recycling and discharge standards will be re-filtered through the wastewater tank 70 and the barrel 10, and it is indeed environmentally friendly.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
