Long-path filtering device for water

Abstract

The invention is a long-path filtering device for water. A coarse screening box, a secondary screening box, and a tertiary screening box are arranged to purify the sewage for multiple times, and the multiple screening boxes, multiple screen nets and a conical screening device are arranged to lengthen the flow path of the sewage; and a plurality of water inlet flow passage grooves and water outletflow passage grooves are arranged in a conical filter table, so that the flow path of the sewage subjected to secondary filtration in the water flow passage grooves is lengthened, and the sewage is infull contact with a plurality of fine screen nets in the water flow passage grooves to enhance the screening efficiency; and multiple water storage chambers are arranged, so that the sewage filteredto different degrees can be obtained.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a long-path water filtration device. Background technique [0002] Water filtration is a medium for filtering and treating other impurities. It is a filtration method that effectively separates solids and gases through the dissolution of water; water filtration is a method for water treatment, which uses filter media to suspend water Solid removal, water filtration is divided into ordinary filtration and microporous filtration. Generally, activated carbon and quartz sand are used to filter drinking water. Existing household water dispensers can not only remove impurities, rust, sediment, colloid, bacteria, and viruses It can also remove harmful radioactive particles, organic matter, fluorescent substances, and pesticides, as well as water alkali and heavy metals in the water; and the current types of wastewater include domestic wastewater, industrial wastewater, electrop...

[0002] Water filtration is a medium for filtering and treating other impurities. It is a filtration method that effectively separates solids and gases through the dissolution of water; water filtration is a method for water treatment, which uses filter media to suspend water Solid removal, water filtration is divided into ordinary filtration and microporous filtration. Generally, activated carbon and quartz sand are used to filter drinking water. Existing household water dispensers can not only remove impurities, rust, sediment, colloid, bacteria, and viruses It can also remove harmful radioactive particles, organic matter, fluorescent substances, and pesticides, as well as water alkali and heavy metals in the water; and the current types of wastewater include domestic wastewater, industrial wastewater, electroplating wastewater and heavy metal wastewater; The treatment methods of various wastewater mainly include physical treatment methods, chemical treatment methods, and biological treatment methods; pretreatment units in the prior art are used for pretreatment processes of urban wastewater, which can include coarse sieving, medium sieving, crushing, flow measurement, Treatment methods such as slag removal and flotation; while the existing water filtration devices often only screen once through a simple screen for water pretreatment; the process is simply to spray sewage on the screen; this leads to the screening of sewage The path is too short, and the contact area with the screen is not enough, and the screening time is too short; it is also impossible to screen out sewage with different purification degrees
