Large-tonnage water treatment equipment

Abstract

The invention discloses large-tonnage water treatment equipment. The large-tonnage water treatment equipment comprises a three-stage water filter tank cast under the ground as well as a three-stage purification tank and a purified water storage tank which are mounted on the ground, wherein an input end of the three-stage water filter tank is connected to a drain pipe through a pipeline; an output end of the three-stage water filter tank is connected to an input end of the three-stage purification tank through a lift pump; an output end of the three-stage purification tank is connected to the purified water storage tank through a high-pressure pump; an output end of the purified water storage tank is connected to a purified water supply end; the bottom inside the three-stage purification tank is filled with a gravel layer; a filter screen is laid at the top of the gravel layer; three stages of filter bins are arranged above the filter screen; a high-pressure composite membrane is mounted on the inner side of the purified water storage tank. According to the large-tonnage water treatment equipment, three-stage water filtering treatment and three-stage purification treatment are adopted totally; then drug purification treatment is performed, the high-pressure pump and the high-pressure composite membrane are matched for use finally, and the purified water can reach the drinking standards.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a large-tonnage water treatment device, and belongs to the technical field of water purification devices. Background technique [0002] Water treatment methods include physical treatment and chemical treatment; physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. The most important adsorption method is to use activated carbon for adsorption. The method is to pass the water through the filter material, so that the larger impurities cannot pass through, and then obtain cleaner water; in addition, the physical method also includes the precipitation method, which is to let the impurities with a smaller specific gravity float on the water surface and remove them, or the specific gravity Larger impurities are deposited below, and then obtained; chemical methods are to use various c...

[0002] Water treatment methods include physical treatment and chemical treatment; physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. The most important adsorption method is to use activated carbon for adsorption. The method is to pass the water through the filter material, so that the larger impurities cannot pass through, and then obtain cleaner water; in addition, the physical method also includes the precipitation method, which is to let the impurities with a smaller specific gravity float on the water surface and remove them, or the specific gravity Larger impurities are deposited below, and then obtained; chemical methods are to use various chemicals to convert impurities in water into substances that are less harmful to the human body, or to concentrate impurities. The chemical treatment method with the longest history should be used When alum is added to the water, the volume of impurities in the water will increase after they are assembled, and the impurities can be removed by filtration; the existing large-tonnage water treatment system occupies a large area, and it is difficult to form a complete treatment system. The treated water source reaches Less than the usage requirements
