Solar energy and potential energy wastewater recycling system

Abstract

The invention discloses a solar energy and potential energy wastewater recycling system. The system is modified on an original waterway pipeline and comprises water inlet pipelines, first U-shaped pipelines, second U-shaped pipelines, sewage discharging pipelines, water drawing pipelines, water tanks, wastewater water inlet pipelines, water pumps, wastewater water supply pipelines, water supply main pipelines, tap water entering toilet flushing pipelines, check valves and toilet flushing pipelines, wherein each water inlet pipeline is connected with a corresponding hand washing pool drainage pipeline, the other end of each water inlet pipeline is connected with one end of the corresponding first U-shaped pipeline, and the other end of each first U-shaped pipeline is connected with the corresponding sewage discharging pipeline; each interface connected with one end of the corresponding water drawing pipeline is formed in the lower side of the middle of the corresponding second U-shapedpipeline, and the other end of each water drawing pipeline communicates with the interior of the corresponding water tank; and the first U-shaped pipelines can filter large particles in wastewater. According to the system, the wastewater used at the upper layer in public building is collected and then used as toilet flushing water at the adjacent layer or the lower layer, so that the utilization rate of water resources is improved.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically relates to a solar energy and potential energy wastewater recycling system. Background technique [0002] Freshwater resources are very limited resources. The total amount of fresh water resources in my country is only 1 / 4 of the world average. The actual amount of fresh water resources available is one of the 13 countries with the poorest water resources per capita in the world. Urban residents’ water consumption accounts for 1 / 10 of my country’s total water consumption. Schools, apartments and other public places wash basins with a large flow of people, and most of the outflowing wastewater is directly discharged into sewer pipes, which are not fully utilized. The sewage treatment unit has increased the workload, increased the primary investment cost, and increased energy consumption, and more importantly, wasted precious water resources. In order to improve the utili...

Problems solved by technology

[0003] The existing domestic wastewater recycling system, such as CNIO8086415A, has the advantages of simple structure and convenient use. After the domestic wastewater recycling system is filtered layer by layer, the hair that is difficult to remove in the water is also filtered out, and The filters and net bags used in the system are movable and detachable structures, which are easy to clean and replace; the disadvantage is that it is mainly used for household wastewater treatment, directly using power resources, which leads to an increase in operating costs and does not make the entire building a A water recycling system; in addition, because the system of CNIO8086415A is aimed at domestic waste water treatment, an additional water pump device is required to transport the treated waste water to the toilet water inlet pipe and the mop water inlet pipe, which increases the power cost
