Description

Glass pumice filter for water treatment

Technical Field

The utility model relates to a filter technical field, concretely relates to a glass pumice filter for water treatment.

Background

Pollutants in rivers and lakes in China are divided into direct pollutants and indirect pollutants, and the sources of the pollutants comprise domestic waste water and industrial production sewage; the pollution to water bodies caused by random discharge of industrial sewage of electroplating plants, paper mills, pharmaceutical factories, printing and dyeing plants, chemical plants and the like is great; the domestic sewage contains a large amount of detergents and domestic garbage penetrating liquid, so that the content of nitrogen and phosphorus in the water body can be increased, and the eutrophication degree of the water body is increased. In recent years, due to the fact that a great amount of chemical fertilizers and pesticides are applied, pesticide and chemical fertilizers which are not absorbed by crops continuously enter river channels along with rainwater, water eutrophication is caused, various chemical substances, organic pollutants and harmful heavy metals are deposited on water bottom to form black and odorous sludge, and a great amount of H is released from the water bottom sludge₂S、SO₂Harmful gases such as NO, the content of organic matters, nitrogen and phosphorus compounds in water is continuously increased, algae and plants in water are propagated in a large quantity, the organic matters are continuously decomposed to consume oxygen in the water in a large quantity, and the water body is caused to become odorous, the ferrous sulfide and other compounds formed by metal ions and sulfur ions in the water cause the water body to be blackened, the concentration of the oxygen in the water and the definition of the water body are greatly reduced, the fish and shrimp anoxia death in the water is caused, an aquatic ecosystem is destroyed, the water body loses self-purification capability, pollutants in bottom mud are suspended in the water body and flow and diffuse along with the water body, and the pollution to soil and air is also caused.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing a glass pumice filter for water treatment.

Realize the utility model discloses the technical scheme of purpose is: the utility model provides a glass pumice filter for water treatment, has filter body, filter upper cover and filter lower cover, the filter body with filter upper cover flange joint, filter body and filter lower cover flange joint, the inside glass pumice filter material that is filled of filter body, the filter upper cover is connected with the outlet pipe, the filter lower cover is connected with the inlet tube.
