Centralized whole-house water purification system for residence community

Abstract

The invention discloses a centralized whole-house water purification system for a residence community. The system comprises a prefilter, wherein the prefilter is connected to a municipal tap water pipe through an electromagnetic switch; the prefilter is connected with a low-voltage switch; one side, close to the low-voltage switch, of the prefilter is connected with a first TDS detector; one sideof the first TDS detector is connected with a first ultrafiltration membrane and a second ultrafiltration membrane, and the first ultrafiltration membrane and the second ultrafiltration membrane are communicated mutually; one side of the second ultrafiltration membrane is connected with a water softener; the water softener is connected with a salt tank; one side of the water softener is separatelyconnected with a first solenoid valve and a precision filter; one side of the precision filter is connected with a daily washing water system through a first household valve. The water purification system has the beneficial effects that a water purifier is operated at high water efficiency; wastewater is collected by a special container after washing for flushing toilets or greening; no wastewater is discharged; water is greatly saved.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a centralized whole-house water purification system for residential quarters. Background technique [0002] With the improvement of people's living standards, people's demand for high-quality drinking water has further increased, especially the demand for pure water is very huge. The direct drinking water in public areas such as residents’ homes or office buildings, hotels, shopping malls, airports, and high-speed rail stations in existing residential quarters is mainly supplied by installing household pure water filters or bottled pure water, but these two water supply methods have major disadvantages and inconvenience; first of all, due to consideration of household use, household pure water filters are small in size and simple in water purification process, and the quality and stability of pure water need to be further improved; secondly, household pure water filters have a s...

Problems solved by technology

The direct drinking water in public areas such as residents’ homes or office buildings, hotels, shopping malls, airports, and high-speed rail stations in existing residential quarters is mainly supplied by installing household pure water filters or bottled pure water, but these two water supply methods have major disadvantages and inconvenience; first of all, due to consideration of household use, household pure water filters are small in size and simple in water purification process, and the quality and stability of pure water need to be further improved; secondly, household pure water filters have a small water output and cannot It can be used as soon as it is opened, and the filter element of the water purifier needs to be replaced or backwashed regularly after the filter is saturated, which is very troublesome. If the filter element is not cleaned or replaced in time, it is very likely to cause secondary pollution; the disadvantage of pure water in barrels is due to packaging costs, transportation The price is high due to cost and other reasons. If it is not used up in time after opening, it will also cause expiration or secondary pollution. At present, there are a lot of pure water in barrels on the market, and the quality of pure water is also uneven.
