Reclaimed water self-circulation system in the building area

Abstract

The invention relates to a reclaimed water self-circulating system for a residential quarter with buildings. According to the invention, the top floor of each building is provided with a top-floor water tank connected with sanitary ware; a tap water facility arranged at the top floor is connected with a bottom-floor water tank arranged at a lower floor; the interior of each bottom-floor water tank is divided into a sewage side and a reclaimed water side through a filter; the reclaimed water side is connected with sanitary ware arranged at the floor; the bottom-floor water tank arranged at the ground floor is connected with a reclaimed water pool; an ascending water supply pipeline connected with the top-floor water tank is arranged in the reclaimed water pool; the top end of the ascending water supply pipeline is connected with the reclaimed water sides of the bottom-floor water tanks located at the middle floors through ascending branch water supply pipelines; the side end of the reclaimed water pool is connected with a rain pipe communicated with a rain tank; the central part of the rain pipe is connected with the sewage sides of the bottom-floor water tanks of every floor and with the top-floor water tank through branch rain pipes; and water level indicating buoys are arranged in the top-floor water tank, the bottom-floor water tanks and the reclaimed water pool. The reclaimed water self-circulating system provided by the invention has the advantages of conservation of resources, exemption from shortage of reclaimed water, capacity of preventing decrease of the water level in a city, etc.

Description

technical field [0001] The invention relates to a sewage recovery and reuse technology, in particular to a reclaimed water self-circulation system in a building area. 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 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 basically occur simultaneously with the generation of sewage...

AI Technical Summary

Problems solved by technology

Since the development of reclaimed water supply in our country is still in its infancy and the network is not extensive, many buildings have installed reclaimed water systems, but they are in an embarrassing state where there is no reclaimed water available and they have to use drinking water; Situation of high transportation costs and restricted use

At the same time, the transportation of sewage and reclaimed water increases the cost of municipal construction

The current building design basically collects the rainwater on the roof through the pipeline and discharges it directly to the sewage system, wasting the water resources that can be used
