The invention discloses a microfiltration membrane filter tank, which is characterized in that the water inlet and the water outlet are arranged on the same side of the tank body, a U-shaped water inlet is arranged at the water inlet, and the upper end of the U-shaped water inlet is connected with the water inlet. The lower end of the type water inlet tank is open, and a group of flat filter elements are vertically arranged in the pool body. The filtrate outlet nozzle of the flat filter element is connected to the water outlet through the general filtered water collection tank. The flat plate filter element includes filter cloth arranged on the surface of the filter element, the filter cloth is covered outside the sheet type filter frame, a filtrate collection pipe is arranged on one side of the sheet type filter frame, and the filtrate outlet nozzle is connected with the filtrate collection pipe. A 2-4 mm thick diatomite and anion exchange resin mixed filter membrane is formed on the filter cloth on the surface of the flat filter element, and the ratio of the two is 1:1. The invention has the advantages of simple structure, small water head loss, improved operation cycle, greatly increased adsorption of organic matter, and greatly improved filtering effect.
Description
Technical field: [0001] The invention relates to the technical field of urban tap water treatment, in particular to a microfiltration membrane filter tank and a filtration method thereof. Background technique: [0002] Water source pollution is a common problem facing the world today, especially the problem of eutrophication pollution. When the water source is polluted, due to the limitation of the conventional water purification process, the safety of the treated drinking water is difficult to guarantee, especially after the cyanobacteria outbreak in Taihu Lake in 2007, the most common complaint about the water quality is the fishy smell in the water . At the same time, for lake water with low turbidity, conventional clarification and filtration technologies are difficult to meet the requirements of drinking water treatment. [0003] Diatomite powder covering filtration technology is a new technology that uses diatomite powder to filter raw water between membrane technolo...
