Central water purification equipment and membrane system cleaning method thereof

Abstract

The invention discloses central water purification equipment which comprises a raw water tank, a raw water pump, a multi-media filter, an activated carbon filter, a water softener, a precision filter, an NF membrane filter, a high pressure pump, a disinfection device and a water purification tank, wherein a water inlet of the raw water tank is connected with a tap water pipeline; a water outlet of the raw water tank is connected with the water inlet of the raw water pump; the water outlet of the raw water pump is connected with the water inlet of the multi-media filter; the water outlet of the multi-media filter is connected with the water inlet of the activated carbon filter; the water outlet of the activated carbon filter is connected with the water inlet of the water softener; the water outlet of the water softener is connected with the water inlet of the precision filter; the water outlet of the precision filter is connected with the water inlet of the NF membrane filter; the water outlet of the NF membrane filter is connected with the water inlet of the high pressure pump; the water outlet of the high pressure pump is connected with the water inlet of the disinfection device; the water outlet of the disinfection device is connected with the water inlet of the water purification tank. The central water purification equipment provided by the invention is simple in structure, can provide high-quality water, can save water resources and can also reduce the equipment operation cost.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a central water purification device. Background technique [0002] In the prior art, the tap water produced by the waterworks passes through the municipal pipe network and then flows into households and other households as drinking water for the public to use. However, the existing tap water purification process can only remove about 20% of the organic matter in the water source, while the municipal administration Water delivery equipment such as nets are outdated and will cause secondary pollution. In addition, water plants often use chlorine for disinfection, and the combination of chlorine and organic matter will produce new carcinogens. The above factors make tap water unable to meet the drinking requirements of direct drinking water. Now In some building water supply systems, the drinking-grade water needed by residents still needs to be purchased and equipped with water purifiers...

[0002] In the prior art, the tap water produced by the waterworks passes through the municipal pipe network and then flows into households and other households as drinking water for the public to use. However, the existing tap water purification process can only remove about 20% of the organic matter in the water source, while the municipal administration Water delivery equipment such as nets are outdated and will cause secondary pollution. In addition, water plants often use chlorine for disinfection, and the combination of chlorine and organic matter will produce new carcinogens. The above factors make tap water unable to meet the drinking requirements of direct drinking water. Now In some building water supply systems, the drinking-grade water needed by residents still needs to be purchased and equipped with water purifiers by each family. The cost is high, and the quality of purified water is different, which is not conducive to management;

[0003] Moreover, the current conventional water purification equipment is composed of three filters, sand filter, carbon filter and microfiltration, which are connected through pipelines. Suspended solids in the water cannot be removed, and the water is not safe enough to eat and cannot meet the needs of domestic water and drinking water
