Water purifying filter

Abstract

The invention provides a water purifying filter. A water purifying material layer is arranged in a barrel, the upper end surface of the water purifying material layer is connected with a water purifying material density adjusting device, the lower end surface of the water purifying material layer is connected with a support base, the support base is connected with the inner wall of the barrel, a water purifying material takes activated carbon with high specific surface area and a macromolecular water purifying material as main components and has high adsorption capacity for pollutants, multiple pollutants can be removed simultaneously and efficiently, a structure formed by connecting multiple filter element materials in series can be replaced, the structure of water purifying equipment canbe simplified, and promotion of the water purifying equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification filter. Background technique [0002] With the increase of population and the development of industry and economy, the pollution of surface water system is becoming more and more serious. Factory sewage and domestic sewage make the national high-quality water source decrease continuously; groundwater pollution is even more shocking. Landfill, septic tank, mine pollution, factory pollution Underground sewage discharge makes nearly 60% of the country's groundwater quality "poor". At present, my country's waterworks still use traditional treatment processes, which cannot effectively remove most of the pollutants. More than 2,100 organic and inorganic pollutants have been detected in the water. [0003] For different types of pollutants, a variety of water purification materials have been developed and used in water purifiers and other equipment. How...

Problems solved by technology

However, the existing materials all have problems such as narrow processing range, high cost, or risk of secondary pollution: for example, PP cotton is only for the removal of large particles such as suspended solids, sediment, rust, and colloids in water, and for bacteria, organic molecules, etc. None can do anything; commonly used activated carbon can remove residual chlorine, pesticide residues, pigments, etc., but cannot effectively adsorb bacteria, calcium and magnesium ions, etc.; RO (reverse osmosis) membrane can remove most of the metal ions, but it also removes the harmful substances that are beneficial to the human body. minerals, and the cost is high; KDF can effectively treat residual chlorine and heavy metals in water, and inhibit the growth of microorganisms in water, but there is still the problem of secondary pollution by heavy metals

[0004] In actual use, in order to achieve the effect of cleaning water sources and reducing biological pollution of water purification materials, sodium hypochlorite is generally used to sterilize the influent water, and the active chlorine introduced thereby will cause irreversible damage to water purification materials, making the water purification materials Water performance rapidly degrades beyond use

Therefore, in order to prolong the service life of water purification materials, the influent water needs to be dechlorinated after disinfection to meet the requirement that the residual chlorine content in the influent water is less than 0.1ppm. This type of operation significantly increases the operating cost
