Circulation reusing device for domestic water

Abstract

The invention discloses a circulation reusing device for domestic water. The invention is characterized in that the device comprises a wastewater tank (2), a circulation water tank (1), a wastewater collection device (5), a filtering and purifying device (15), a wastewater pump (11), a first-level water pump (13), a second-level water pump (14), a circulation water intake pipe (4) and a wastewater intake pipe (19), wherein the circulation water tank (1) is communicated with the filtering and purifying device (15) through the circulation water intake pipe (4) and the second-level water pump (14), and the filtering and purifying device (15) is communicated with a water inlet pipe (8) by the first-level water pump (13) through a three-way valve (9); the wastewater tank (2) is communicated with the wastewater collection device (5) through the wastewater intake pipe (19) and the wastewater pump (11); and the wastewater collection device (5) is communicated with the water inlet pipe (8) through the three-way valve (9). The wastewater tank (2) and the circulation water tank (1) are arranged at the position higher than a water tank (24) of a water closet. The volumes of the wastewater tank (2) and the circulation water tank (1) are more than 1m<3>. The classification recycling of the domestic wastewater can be realized based on different usages, and then the domestic water can be recycled after different processes according to the collected different water qualities.

Description

technical field [0001] The invention relates to a water-saving device, in particular to a water-saving device for recycling domestic water. Background technique [0002] With the continuous deterioration of the water environment, water resources are increasingly precious. How to save water has become the most concerned issue in people's lives. Household domestic water includes drinking water for cooking and drinking; washing water for washing dishes, washing rice, washing vegetables, bathing, and laundry; and waste water for flushing toilets. Different uses have different requirements for water quality. Drinking water has the highest requirement and must meet hygienic requirements, and it cannot be recycled after use; washing water has general requirements for water quality, and it can be recycled after being purified once used. The water quality requirements are not high, and general waste water can be used, and the toilet water cannot be recycled after use. At present, m...

Problems solved by technology

[0004] However, this water-saving device regards various used domestic water as waste water for flushing the toilet, and some domestic water is only used once, and the water quality is better and can be well utilized. All of it is discharged as waste water, and no real In the sense of recycling water, it still causes a large waste of water resources
