Technical Field

The invention relates to the field of water supply, in particular to a reclaimed water recycling system for a multistoried building in a public place.

Background

The total amount of water resources in China is 2.8 billion cubic meters, and the water resources are discharged at 109 th position in the world. Under the restriction of factors such as development and utilization, flood, ecological needs and the like, the water resource which can be practically utilized is about 8000-9000 billion cubic meters. From 1949 to the beginning of this century, our actual water usage has increased from about 1000 to about 5400 billion cubic meters. Account for 50% -60% of the water which can be used practically, but in cities of China, the shortage of urban water resources is a fact that the cities are rapidly expanded and the distribution of fresh water resources is unbalanced. At present, statistical data shows that more than 400 cities in more than 600 cities in China are in a water shortage state.

In the face of the water consumption increasing and the increasingly tense urban water shortage in the urban development process, the shortage of fresh water resources in cities becomes a bottleneck for restricting the realization of social sustainable development. Although countries have taken a number of measures. Such as: the contradiction is solved and relieved by measures such as water transfer across drainage basins, rainwater collection and utilization, sewage treatment and reclaimed water utilization, and the like, but with the economic development, the improvement of the living standard of urban residents and the industrial development, the shortage of fresh water resources is still difficult to solve the existing problems in a short time, and people always seek an ideal technical solution.

Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

Example 1

The embodiment provides a water reuse system in multi-story buildings in public places, as shown in fig. 1, 2 and 3, comprising a filter tank 2 and a water storage tank 3 communicated with the filter tank 2.

The installation height of the top surface of the water storage tank 3 is smaller than that of the bottom surface of the filter tank 2. The water inlet of the filter tank 2 is connected with a reclaimed water pipeline, and the water storage tank 3 is communicated with a flushing device positioned below the water storage tank 3.

Each layer in the multi-storey building is provided with a filter tank 2 and a water storage tank 3 communicated with the filter tank 2. The water storage tanks 3 positioned in the superstructure in the upper and lower adjacent two floors are communicated with the flushing equipment positioned in the lower building.
