Description

Water supply system for floor flushing with combination of reclaimed water reuse and rainwater utilization

technical field

The utility model relates to a water supply system, in particular to a water supply system for flushing toilets on floors.

Background technique

Most of the water for flushing toilets in existing high-rise buildings is taken from municipal water, and needs to be supplied through booster pumps. In some projects, in order to save water, it is considered to install reclaimed water treatment devices in the basement, and after the sewage is treated, the booster pump is used to supply water to the flushing water points on the floors to achieve water saving purposes. However, this method does not give priority to the use of rainwater, but uses sewage with poor water quality to prepare toilet flushing water through a relatively complicated process, and the treated water needs to be supplied to the floor through a booster pump.

Contents of the invention

The technical problem to be solved by the utility model is to provide a water supply system for toilet flushing on the floor which combines reclaimed water reuse and rainwater utilization, aiming at solving the above-mentioned problems.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

The utility model comprises: a rainwater collection box and domestic waste water and condensed water adjustment pools arranged in the refuge layer or equipment layer in the middle of a high-rise building; the rainwater collection box is connected with the roof rainwater system through a rainwater discarding device; the rainwater collection One end of the tank, the roof rainwater system and the rainwater abandonment device are connected together and then discharged into the rainwater system; the other end of the rainwater collection box is connected with the clear water pool through the rainwater treatment device; The waste water in the high area and the condensed water in the high area are connected; the domestic waste water and the condensed water regulating pool are connected with the clear water pool through the waste water treatment device; The clean water pool is also connected to the domestic water system; the clean water pool is connected to the low area flushing system and the waste water pipe through pipelines.

Compared with the prior art, the beneficial effect of the utility model is that the rainwater on the roof of the high-rise building, the domestic waste water in the high area and the condensed water can be fully recycled, which not only plays a role in regulating and storing the municipal rainwater, but also saves the municipal water consumption .

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As can be seen from Fig. 1: the utility model comprises: the rainwater collection box 2 and the domestic waste water and condensed water regulating pool 3 that are placed in the refuge layer or the equipment layer 1 in the middle of a high-rise building; The roof rainwater system 5 is connected; one end of the rainwater collection box 2, the roof rainwater system 5 and the rainwater discarding device 4 is connected and discharged into the rainwater system 6; the other end of the rainwater collection box 2 is connected to the rainwater treatment device 7 and The clean water pool 8 is connected; the domestic waste water and the condensed water regulating pool 3 are respectively connected with the high area waste water 9 and the high area condensed water 10; the domestic waste water and the condensed water regulating pool 3 are connected to the clean water pool through the waste water treatment device 11 8 are connected; the high area wastewater 9, the high area condensed water 10 and the waste water treatment device 11 are connected in parallel to the waste water system 12; the clean water pool 8 is also connected to the domestic water system 13; the clean water pool 8 It is respectively connected with the low zone flushing system 14 and the waste water pipe 15 through pipelines.

Water saving and energy saving are one of the most important national policies in our country. In order to make more and more buildings meet LEED standards and become green buildings, this utility model adapts measures to local conditions in high-rise and super high-rise buildings, and makes full use of high-quality rainwater on the roof and high-rise areas. After the wastewater is treated, it can directly become toilet flushing water in the low area without a pressurization device, which saves both energy and water.

The utility model combines the existing reclaimed water reuse and rainwater utilization systems in the middle floors of high-rise buildings, such as the refuge floor or the equipment floor, so as to realize the storage and reuse of urban rainwater and the recycling and reuse of waste water. The equipment is located on the middle floor, so that the treated clean water can be directly supplied to the lower floor for flushing by gravity without using a pump.

The utility model is aimed at collecting rainwater, waste water and condensed water with different raw water qualities separately. After the collection water tank reaches the high liquid level, open the electric valve on the rainwater, waste water and condensed water, and discharge the excess water to the outside. After the raw water enters different collection water tanks, it can be separated The two different methods of membrane bioreactor and filtration are used for separate treatment, but the treated water that reaches the standard is set in the same clean water tank for use together, and the rainwater with better water quality can be treated first according to the water level control of the rainwater tank. When the amount of rainwater collected cannot meet the toilet flushing requirements, waste water is used as raw water for reclaimed water treatment, and the treated clean water is directly supplied to low-level floors with water for flushing toilets by gravity, so as to achieve the purpose of saving water and energy while making full use of renewable resources .

In the choice of rainwater and waste water, priority should be given to the use of rainwater. In seasons with abundant rainfall, rainwater alone may be able to meet the toilet flushing water in low areas, and waste water can be used to supplement it in dry seasons. The treated clean water uses gravity to directly supply the toilet flushing water in the low area, which saves the energy consumption of pressurization.
