Adsorption device of water purifying system

Abstract

The invention discloses an adsorption device of a water purifying system. The adsorption device comprises an adsorption chamber. An adsorption layer and a vertical water distribution pipe are arranged in the adsorption chamber. The two ends of the vertical water distribution pipe penetrate out of the adsorption layer respectively. The upper end of the vertical water distribution pipe is connected with a water distributor. The lower end of the vertical water distribution pipe extends out of the adsorption chamber. The adsorption chamber below the adsorption layers is connected with a water outlet pipe. The adsorption layer comprises a diatomite layer, a fluffy cotton layer, a silica layer and an activated carbon layer sequentially from bottom to top according to the thickness ratio of 3:2:1.5:1. The multi-layer adsorption layer is arranged in the adsorption chamber so that trace toxic and harmful matter left in water can be greatly reduced, water drinking safety is guaranteed, and a water source can be dispersed on the adsorption layers evenly through the disc type small hole water distributor. Besides, large water flow fluctuation can not be generated, the adsorption effect of the whole adsorption chamber is good, and service life is long.

Description

technical field [0001] The invention relates to the field of water supply treatment equipment, in particular to an adsorption device for a water purification system. Background technique [0002] Human activities will discharge a large amount of industrial, agricultural and domestic waste into the water, polluting the water body. At present, more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year in the world, polluting 5.5 trillion cubic meters of water. Fresh water, which is equivalent to more than 14% of the total global runoff, is becoming more and more serious. Water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development. According to the survey of world authoritative organizations, In developing countries, 80% of various diseases are spread by drinking unsanitary water, and drinking unsanitary water causes at least 20 million...

[0002] Human activities will discharge a large amount of industrial, agricultural and domestic waste into the water, polluting the water body. At present, more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year in the world, polluting 5.5 trillion cubic meters of water. Fresh water, which is equivalent to more than 14% of the total global runoff, is becoming more and more serious. Water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development. According to the survey of world authoritative organizations, In developing countries, 80% of various diseases are spread by drinking unsanitary water, and drinking unsanitary water causes at least 20 million deaths in the world every year, so water pollution is called "the world's number one killer". Chemical method is the most mainstream method in water treatment methods. Generally, water treatment methods mainly include several steps of reaction, precipitation, filtration and sterilization. After these steps, the raw water can generally meet the standard of drinking water, but the traditional purification Water technology is to do nothing to deal with some toxic and harmful substances in raw water that may cause major hidden dangers to human health although their content is low.
