Classified recycling and reutilization system based on domestic sewage

Abstract

The invention relates to a classified recycling and reutilization system based on domestic sewage. The classified recycling and reutilization system based on domestic sewage comprises a kitchen recycled water storage tank, a washing machine recycled water storage tank, a recycled bath water storage tank, an outdoor recycled water storage pond, three-way solenoid valves, glass tubes with nano-coatings and turbidity sensors, wherein the turbidity sensors and the three-way solenoid valves are electrically connected with a control system, water of the kitchen recycled water storage tank, the washing machine recycled water storage tank and the recycled bath water storage tank converges through an indoor toilet flushing pipeline and then is delivered to a toilet for flushing the toilet, and water of the outdoor recycled water storage pond is delivered to residential areas through pipelines for serving as water used for plant irrigation, pavement washing and car washing. The system can be laid during building of new residential areas, and also can be used for reconstruction installation in the existing residential areas, and thus the universality is wide; meanwhile, the device is low in use and operation costs, and good in generalizability, water resources can be saved, and the water use cost of residents also can be reduced. The classified recycling and reutilization system is simplein structure, is convenient to use, is safe and reliable, is low in cost, is low in energy consumption, and is obvious in sewage separation effect.

Description

technical field [0001] The invention relates to the technical field of energy reuse, in particular to a recyclable and reuse system for domestic sewage in a community. Background technique [0002] At present, reclaimed water reuse systems in communities all over the country are generally put into use and have high maintenance costs. In 2012, the Beijing Ivy Institute for Sustainable Development randomly surveyed 34 residential quarters built in 2002-2004 and found that only 2 were confirmed to be in operation. By visiting and surveying nearly 30 residential areas and many colleges and universities in Chongqing, we found that almost all the residential areas and colleges have a very low secondary utilization rate of water. Taking bathing as an example, only a small part of the water is relatively turbid. Foam water cannot be reused, and most of the water is generally discharged directly through the sewer. This part of the water can be used as clean water for daily household...

Problems solved by technology

By visiting and surveying nearly 30 residential areas and many colleges and universities in Chongqing, we found that almost all the residential areas and colleges have a very low secondary utilization rate of water. Taking bathing as an example, only a small part of the water is relatively turbid. Foam water cannot be reused, and most of the water is generally discharged directly through the sewer. This part of the water can be used as clean water for daily households (cleaning, flushing toilets), resulting in a great waste of water resources. At the same time, users The cost of water is also high
