Water reusing system and method in high-rise building

Abstract

The invention discloses a water reusing system and a water reusing method in a high-rise building. The high-rise building comprises a plurality of storeys from top to bottom; the recycled water reusing system comprises a recycled water main pipe, a sewage main pipe, water distribution boxes positioned in the storeys respectively and recycled water treatment units arranged in an equipment room; multiple water using devices in each storey are communicated with a blow-off pipe through branch pipes respectively; the blow-off pipe in each storey is connected with the main pipe and then connected with the recycled water treatment unit; the recycled water treatment unit in each storey is communicated with the sewage main pipe, and is used for discharging treated dirt into the sewage main pipe; the recycled water treatment unit conveys the qualified recycled water after treatment into the water distribution box in a lower storey; the water distribution box in each storey is communicated with atap water inlet pipe and the recycled water main pipe respectively so as to supplement water. By virtue of the own height difference of the building, staggered-storey reuse of the sewage after up-to-standard treatment in the building is achieved, so that the reusing cost after the sewage treatment is lower and the management is convenient; the water reusing system can be flexibly erected according to actual needs and is movable and detachable, so that the water reusing system has strong practicality in an urban water reusing project and a wide prospect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and reuse, in particular to a water reuse system and method for high-rise buildings. Background technique [0002] With the development of social economy and the rapid growth of population, the water consumption for production and domestic use is constantly increasing, coupled with the unscientific use of water by human beings, the available water resources are decreasing sharply. At present, the water resource crisis has become a major resource and environmental problem faced by all countries. In order to solve the problem of urban water shortage, we should actively carry out research on sewage reuse and increase the rate of sewage reuse while increasing water conservation efforts and controlling urban water pollution. [0003] Judging from the current stage, my country's urban housing environment is still dominated by high-rise residential areas with dense buildings, and the problem of...

Problems solved by technology

[0003] Judging from the current stage, my country's urban housing environment is still dominated by high-rise residential areas with dense buildings, and the problem of reclaimed water recycling is difficult to solve. If the traditional peripheral sewage treatment plant is used for centralized treatment, it will be carried out through the reuse pipe network. If water distribution is required, then improving the pipe network will be a systematic project that requires a lot of manpower, capital, and technical input, and the radiation range is limited, and the effective utilization rate of reused water is low.

[0004] Therefore, considering that urban high-rise buildings with complex functions and large building areas have a large amount of wastewater resources in the buildings, if the reclaimed water reuse can be well planned and designed, the traditional centralized sewage treatment devices occupy a large area and consume a lot of water. With the disadvantages of high energy efficiency and high pipeline laying costs, the realization of sewage treatment and reuse inside the building can obtain better economic and social benefits, which is of great significance for further promoting social development
