The technical scheme of the utility model is realized in the following way: a device for recycling domestic waste water, its structure includes a water storage tank arranged in the bathroom on the next floor and a waste water collection treatment device that can collect waste water from high-rise buildings, and the lower part of the waste water collection treatment device is equipped with There is a water inlet pipe connected to the water storage tank. The upper part of the water storage tank is equipped with a high water level float switch, and the lower part of the water storage tank is equipped with a low water level float switch that can replenish tap water. The lower part of the water storage tank is connected with the toilet pipe. There is also a tap water replenishment control switch.

The structure of the waste water collection and treatment device can have multiple methods, such as the waste water collection and treatment device can be composed of a waste water confluence pipe connected to the toilet sewer on the upper floor, a filter device arranged at the lower end of the waste water confluence pipe, and a filter device arranged in the middle of the waste water confluence pipe. The shunt pipe, wherein the lower end of the filtering device is provided with a water inlet pipe and an overflow pipe, the water inlet pipe communicates with the water storage tank, the overflow pipe communicates with the floor general sewer pipe, and the lower end of the shunt pipe communicates with the floor general sewer pipe. The waste water collecting and processing device can also include a waste water confluence pipe connected to the toilet sewer on the upper floor and a filter device arranged in the general sewer pipe of the floor. connected. In order to facilitate the replacement of the filter device, an on-off valve is provided on the upper part of the main sewer pipe. When replacing, the valve can be temporarily closed, so that the waste water in the main sewer pipe is intercepted to provide convenience for the replacement work.

In order to meet the needs of different households, the lower part of the waste water confluence pipe is provided with a connection port that is easy to disassemble, the filter device is connected to the lower part of the waste water confluence pipe, and the overflow pipe and the main sewer pipe are also set as a removable connection structure, so that Customers can choose whether to install wastewater collection and treatment devices.

Water taps can also be installed in the lower part of the water storage tank, and waste water can be used for effects such as mopping the floor.

The working principle of the utility model is realized in this way: the domestic wastewater generated on the upper floor flows into the wastewater confluence pipe through the sewer, and then flows into the filter and purification device. The filter and purification device can be installed in the toilet on the next floor, or it can In the main sewer pipe. The filtered waste water enters the water storage tank through the water inlet pipe. When the water storage tank is full, the high water level float switch is disconnected, and the waste water flows back into the main sewer pipe through the overflow pipe to be discharged. When the water in the water storage tank is lower than a certain level , the high water level float switch is opened to let the filtered wastewater continue to pour into the water storage tank; when the water stored in the water storage tank is used up and the filtered wastewater is insufficient, the low water level float switch is activated, and tap water flows into the water storage tank to Make sure to flush the toilet with water.

Due to the adoption of the above structure, the utility model utilizes the domestic waste water of the residents on the upper floor or the domestic waste water discharged into the general sewer by other high-rise residents to be used for flushing the toilet after simple filtration, fully utilizes the domestic waste water, and can effectively save 50% The above domestic water consumption has realized the sustainable utilization of water resources. The utility model is applicable to the installation and use of original buildings, and is also suitable for unified installation and use in the construction of newly-built buildings. Its detachable structure can also be selected and used to meet the needs of residents.

Below in conjunction with accompanying drawing, the utility model is further described.
