DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG.
A disposer 4 for crushing raw garbage is installed on a sink 3 in each house 2 of a building 1 of an apartment house. The raw garbage crushed by the disposer 4 of each dwelling 2 flows into the main drainage pipe 6 through the branch drainage pipe 50 together with the water flown in the sink 3, and flows into the septic tank. The sub-drainage pipe 50 is provided with a pump 62 for suction or pressure feeding in order to facilitate circulation of the crushed garbage in the drainage pipe. In addition, drainage pipe 50
A drainage pipe 51 for collecting the drainage of the washing machine 8 and connecting the drainage pipe 50 to the drainage pipe 50 to connect the drainage to the drainage pipe 50 is provided on the upstream side of the connection portion 7 with the disposer 4. It should be noted that the pump 62 does not necessarily need to be installed if the slopes of the sub-drainage pipe 50 and the sub-drainage pipe 51 are sufficiently set and the flow velocity of the drainage flowing from the sub-drainage pipe 50 and the sub-drainage pipe 51 to the main drainage pipe 6 is sufficient.

According to this embodiment, since the drainage pipe is washed with the laundry drainage containing the detergent and the amount of the drainage water flowing through the drainage pipe increases, the drainage pipe is less likely to be blocked by the garbage.

In addition, although an example of application to an apartment house has been described in the present embodiment, the same effect can be obtained even if the above embodiment is applied to a single-family house.

Although FIG. 1 shows an example in which only the drain pipe from the washing machine 8 is connected to the upstream side of the connecting portion 7 with the disposer 4, another drain source, that is, a bath, is connected to the upstream side of the disposer 4. 5 or a drain from a washroom (not shown) may be connected. These drainage sources may be individually connected to the upstream side of the disposer 4, or a plurality of them may be combined. The combination may be any of the washing machine 8 and the washroom, the washing machine 8 and the bath 5, the washroom and the bath 5, and the bath 5 and the washroom and the washing machine 8. This is because each of the washing machine 8, the bath 5 and the washroom uses a detergent, soap, shampoo or the like having a cleaning action, and the drainage mixed with them is effective in washing the drain pipe. As a drainage source, when used alone, the washing machine 8 and the bath 5 have a large amount of drainage and a large amount of detergent to be used. Good to compare. In addition, in combination, a bath with a large amount of drainage 5
The order of the washing room and the washing machine 8, the washing machine 8 and the bath 5, the washing machine 8 and the washing room or the washing room and the washing machine 8 is good, and the washing action is increased as compared with the case of using them alone.

A second embodiment of the present invention will be described with reference to FIG.

FIG. 2 shows a system for treating raw garbage and waste water that have flowed into and collected from a sink 3 in each house 2 of a building 1 of an apartment house into a main drain pipe 6.

The raw waste and the waste water collected at the end 61 of the main drain pipe 6 are solid-liquid separated by the solid-liquid separator 9, and the solid content is sent to the raw waste processing device 10 and the liquid is sent to the waste water processing device 11. The solid content is fermented by the garbage processing apparatus 10 using microorganisms to reduce the volume and used as fertilizer or is disposed as garbage. Further, the liquid is subjected to the primary treatment and the secondary treatment by the wastewater treatment device 11 and is drained to the sewer pipe 12, but a part of the liquid is subjected to the tertiary treatment by the filtration membrane and the activated carbon to reduce the impurity concentration and to prevent the propagation of bacteria and After disinfecting to prevent the scale from adhering, the water is supplied to the toilet 14 or the like by the pump 13 as reclaimed water and reused.

According to the present embodiment, the amount of water used for cooking in the housing complex is almost the same as the amount of water used in the toilet, and wastewater is not treated more than necessary. The maintenance cost of the device can be reduced.
Also, effective use of water can be achieved.

In this embodiment, the intermediate water treated by the wastewater treatment equipment 11 is pumped by a pump and directly fed to the toilet 14.
Although the example in which the intermediate water is supplied to the toilet 14 is described above, the intermediate water may be temporarily stored in a tank (not shown) installed on the rooftop or the like, and then the water may be supplied from the tank to the toilet 14. Further, although an example of application to an apartment house has been described in the present embodiment, the same effect can be obtained by using the same for a single house as in the first embodiment.

A third embodiment of the present invention will be described with reference to FIG.

In this embodiment, the crushed raw waste and the wastewater that are crushed by the disposer 4 and collected from the main drainage pipe 6 to the main drainage pipe 50 are directly poured into the wastewater treatment facility 111 for treatment. In the configuration of this embodiment, only the disposer drainage from the branch drainage pipe 50 is collected in the main drainage pipe 6 and sent to the drainage treatment device, and the laundry drainage, bath drainage, and toilet drainage are collected in the main drainage pipe 63 of another system. It was configured to send to the wastewater treatment equipment. The wastewater treatment facility 111 is preferably equipped with a function of separating the solid content in the wastewater.

According to this embodiment, the system structure is simplified, so that the cost can be reduced and the reliability can be improved.

An embodiment of the disposer 4 used in the present invention will be described with reference to FIGS. 4 and 5. The disposer 4 used in each of the above-described embodiments may be of a type that can be appropriately operated by the user, but it is efficient to use the disposer described below.

FIG. 4 is a configuration diagram of a disposer, a pump, and a control system of the disposer showing an embodiment. The disposer 4 is a device shown by a thick line in the figure, and includes a motor 42 in a casing 43 below a crushing chamber 41 connected to the drainage port 31 of the sink 3 and a motor 42 penetrating the casing 43.
The rotating body 44 is provided at the tip of the rotating shaft 421. The garbage 32 entering the crushing chamber 41 from the drainage port 31 is the motor 4
2 is brought into contact with the rotating body 44 rotated by 2, and is crushed and washed away by the water supplied from the tap 33 of the tap water.
1 and is discharged to the main drain pipe 6. The raw dust detection sensor 45 installed at the entrance of the disposer 4 detects the raw dust 32 put into the disposer 4, and the detection output 451 of the raw dust detection sensor 45 is input to the control unit 47.

As the raw dust detection sensor 45, an optical sensor or an ultrasonic sensor which can detect the passage of the raw dust in a non-contact manner is suitable, but the drainage port 31 and the crushing chamber 4 through which the raw dust 32 passes.
It may be a mechanical sensor such as a lever switch that is provided in the unit 1 and detects the passage of raw garbage when it comes into contact therewith.

Detection output 45 from the garbage detection sensor 45

Drive 2 Further, the load of the motor 42 is detected by the load detection sensor 46 that detects the load of the motor 42. The load detection sensor 46 is preferably a current sensor that measures the drive current of the motor 42 or a torque sensor that detects the torque of the motor 42. Output 461 of load detection sensor 46
Is input to the control unit 47. The motor 42 is a detection output 451 from the garbage detection sensor 45 and the load detection sensor 46,
When 461 becomes a certain value or less, it is stopped by the command signal 471 from the control unit 47.

Further, the control unit 47 sends a command signal 131 to the pump 13 in accordance with the rotation of the motor 42, and the pump 1
3 is driven and the drainage from the disposer 4 is pumped or sucked to flow downstream. The drive of the pump 13 may be synchronized with the rotation of the motor 42, and may be delayed for a time when the crushed garbage and water are accumulated in a predetermined amount. Further, the control unit 47 may control the driving force of the pump 13 in proportion to the detection output 461 as in the control of the electromagnetic valve 34.

According to this embodiment, since the disposer and the pump are operated only when the garbage is put into the disposer, the amount of electric power used can be saved.

It is determined based on the detection output 461 from the load detection sensor 46. For example, when the detection output is large, the control unit 47 determines that the amount of raw dust is large in proportion to the detection output 461, increases the opening degree of the electromagnetic valve 34, increases the outflow amount of tap water, and increases the amount of tap water in the disposer 4. The crushed raw garbage that was supplied to and is smoothly discharged. When the detection output is small, the opening degree of the electromagnetic valve 34 is reduced to reduce the outflow amount so that unnecessary water does not flow.

In the present embodiment, the amount of water supplied from the water supply and the pump for driving the drainage can be operated depending on the amount of the raw dust put in the disposer, so that the drainage pipe is less likely to be blocked. Further, since the amount of water and the pump driving pattern can be set according to the amount of raw garbage, the amount of tap water can be minimized and clogging of the drain pipe can be eliminated.

Further, in the above embodiment, the motor 42 for rotating the rotating body 44 by receiving the detection output 451 from the garbage detecting sensor 45 installed at the entrance of the disposer.
