Bitter (brackish) salt water purifying equipment

Abstract

The invention relates to the field of water treatment, and discloses bitter (brackish) salt water purifying equipment. A multi-medium filter, a self-cleaning filter and an ultrafiltration membrane device are applied to pretreatment, and an innovative two-stage reverse osmosis membrane device is taken as a core desalination process, so that the utilization ratio of water is increased effectively. The bitter (brackish) water purifying equipment has the characteristics of saving of water resources, stable running of equipment, good water quality, high automatic degree and long service life of equipment, and can be widely applied to bitter (brackish) water or high-fluoride-water regions; and the drinking water safety of local residents is ensured.

Description

technical field

[0001] The invention relates to water treatment equipment, more specifically to bitter (slightly) salty water purification equipment that can reliably achieve water purification goals and improve water utilization, and belongs to the technical field of water treatment. Background technique

[0002] my country is a country seriously short of water, and the per capita water resources are about 2400m 3 , is only 1 / 4 of the global per capita water volume, and the temporal and spatial distribution is uneven, the water environment is seriously polluted, and the primary low-quality water is widely distributed, especially in the arid inland areas of Northwest China. Due to the lack of precipitation and strong evaporation, water resources are naturally scarce. As the main source of water supply, groundwater generally contains salt and high fluorine content, and there is no alternative fresh water resource in most areas. It is estimated that Inner Mongolia has 3.736 bi...
