Efficient residential building reclaimed water circulation system and application thereof

Abstract

The invention discloses an efficient residential building reclaimed water circulation system which comprises a reclaimed water collection pipeline, a reclaimed water treatment system, a circulating water storage tank, a sewage collection pipeline and a community domestic sewage treatment system. By changing the community pipeline system, high-quality domestic sewage of a single building is concentrated for reclaimed water treatment, and the treated regenerated water is used for flushing a pedestal pan, so that the aims of saving tap water and reducing the pressure of a municipal reclaimed water treatment system are fulfilled; the surplus domestic water for secondary circulation can be used for greening irrigation, fire-fighting water and the like, the discharge amount of domestic sewage isreduced, and the community domestic sewage treatment system and the pressure of municipal sewage holding capacity are reduced; besides, a rainwater drainage system does not need to be connected, rainwater and sewage diversion is achieved, the water inlet and drainage pressure of the reclaimed water treatment system and the domestic sewage treatment system is reduced, the construction cost and theoccupied area are reduced, and during construction, only the building water consumption condition needs to be considered to design the sewage containing capacity of the building reclaimed water treatment system and the community domestic sewage treatment system.

Description

technical field [0001] The invention relates to the technical field of sewage recovery and reuse, in particular to a high-efficiency residential building regeneration water circulation system and its application. Background technique [0002] Reclaimed water is also called reclaimed water. Its water quality is between sewage and tap water. It is non-drinking water that can be used within a certain range after urban sewage and waste water have been purified to meet national standards. It can be used for many purposes in urban landscapes and people's lives. aspect. In order to solve the problem of water shortage, the recycling of urban sewage has been paid more and more attention. Compared with the development of other water sources, the recycling of urban sewage has great advantages. First of all, the amount of urban sewage is huge, stable, not limited by climatic conditions and other natural conditions, and can be recycled. Sewage as a source of recycled water can basicall...

AI Technical Summary

Problems solved by technology

The above reclaimed water systems have the following problems: first, the quality of reclaimed water is not good; second, the reclaimed water system is too centralized, the system process is complex, and the operation and maintenance costs are high, resulting in the installation of reclaimed water systems in many buildings. , is still in the embarrassing state of having no reclaimed water available and having to use drinking water; thirdly, the transportation of domestic sewage and reclaimed water increases the cost of municipal construction; fourthly, most of the domestic reclaimed water reuse systems are currently concentrated in In the north, it is connected to the rainwater drainage system. If the amount of rainwater is large, the water intake of the reclaimed water treatment system will easily exceed the standard, so it is not suitable for rainy areas in the south
