Water-saving system for dormitories of colleges and universities

Abstract

The invention provides a water-saving system for dormitories of colleges and universities. The water-saving system can well collect rainwater from roofs and wastewater of water house; and the collected water can be used for flushing toilets after treatment, so as to achieve an object of saving water. The water-saving system is characterized in that water tanks on the roofs are used to collect the rainwater; water-collecting tanks are installed below water tanks of each floor of water houses to collect wastewater produced by washing faces and clothes; the collected rainwater and wastewater are introduced to toilets in the lower layer so as to flush squatting pans, pedestal pans and urinals by using water pipes. A settling zone is disposed at one side of each water-collecting tank; water left in sponge firstly flows into the settling zone, then flows into a water reserving zone. A sliding door is disposed in the settling zone for cleaning sediments, thereby providing convenience for cleaning sludge. A flowmeter is installed at a water outlet at the bottom side of the water reserving zone of the water-collecting tank. A reading number of the flowmeter is input to a single chip microcomputer water-saving control system through a signal cable; and the data is processed by the single chip microcomputer water-saving control system and output and displayed on a display screen. A water-saving effect can be seen by a student when he / she uses water in the water house, so that student's awareness of water conservation can be improved. The water-saving system can achieve the object of flushing the toilets by using the wastewater and saving the water, and has both economic benefits and social benefits.

Description

technical field [0001] The invention relates to a water-saving system, in particular to a water-saving system for college dormitories. Background technique [0002] my country's water resources have become less and less, therefore, saving water is imperative. Colleges and universities are gathering places of high-quality people, so they should do a good job in water conservation and set an example for the society. Take Tianjin as an example. Tianjin is a place where colleges and universities gather. There are more than 20 colleges and universities of various types, with nearly 400,000 teachers and students, and an annual water consumption of more than 20 million cubic meters. Undoubtedly, the water-saving status of various colleges and universities will directly affect the progress of water-saving work in Tianjin. But at present, due to the difficulty in installing metering devices in college dormitory water rooms and toilets, the main reason is not technical problems, but...
