Embodiment 1

[0033] see Figure 2 to Figure 6 , the above-mentioned flat ceramic membrane filter device 1 is a filter unit, which includes a lower bracket 101 and an upper water collection chamber 102 . The water collection chamber 102 includes an orifice 1023 at the bottom, a surrounding plate 1021, and a top plate 1022 on the top. An inspection hole is opened on the top plate 1022, and the inspection hole flange 104 is fixed. The inspection hole flange 104 is provided with an open inspection hole cover 105 , so as to form a relatively closed space. The water collection chamber 102 is fixedly supported on the bracket 101, and the water collection chamber 102 is provided with a clean water outlet 111 and a reverse cleaning air inlet 103 on the outside of the coaming, and is respectively connected to the clean water main pipe 4 and the backwash through the respective branch valves 3. On the cleaning main pipe 2, the clean water main pipe 4 and the backwash main pipe 2 are respectively conn...

Embodiment 2

[0037] see Figure 7 to Figure 11 , the structure of this embodiment is basically the same as that of Embodiment 1, except that the structure of the upper connecting piece 1101 and the orifice plate 1023 of the flat ceramic membrane module 110 are different, as shown in Figure 9, Figure 10 , Figure 11 shown. In this embodiment, the upper connector 1101 of the flat ceramic membrane module 110 is a threaded structure, and the orifice 1023 at the bottom of the water collection chamber 102 is a plate-shaped member. The circular holes with the same number of series, the size and shape of the holes correspond to the size and shape of the threaded structure of the upper connecting piece 1101 . The upper connecting piece 1101 of the flat ceramic membrane module 110 is inserted into the circular hole on the orifice plate 1023 through the bottom of the bracket 101 from the bottom of the orifice plate 1023. Screw on the large nut 115 on the cylindrical platform, and place the gasket...

Abstract

The invention discloses a flooded modular structure flat plate ceramic membrane filtration system. The system comprises a plurality of flat plate ceramic membrane filtration devices. The flat plate ceramic membrane filtration devices are used as filter units and are arranged in a line or multiple lines to form a large filter system. Each one of the filter units comprises an upper clean water outlet, a reverse cleaning gas inlet and a bottom aeration pipe. The clean water outlet, the reverse cleaning gas inlet and the aeration pipe of each one of the filter units are respectively connected to a corresponding clean water main pipe, a corresponding reverse cleaning main pipe and an aeration main pipe through corresponding branch pipes and electric valves on the branch pipes. The clean water main pipe is connected to a water pump. The reverse cleaning main pipe and the aeration main pipe are connected to a gas storage tank. The whole filter unit is immersed into a raw water tank, and one side of the upper part of the raw water tank is provided with a liquid level sensor. All the electric valves are connected to an electronic control device. The system has a novel structure, is easy to install and use, has small filtering resistance, has matching flexibility, has good regeneration effect and is not easily damaged.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a submerged modular structure flat ceramic membrane filtration system for solid-liquid separation by adopting cluster combination modular structure flat membrane modules. Background technique [0002] In metallurgy, chemical industry, building materials, electric power, mining, breeding, food processing and other industries, a large amount of wastewater will be generated. These industrial wastewater and domestic sewage contain a large amount of suspended solids and solid particles such as dust and impurities, and the color is turbid, and they are directly discharged into natural water bodies, deteriorating the water quality. At present, for wastewater containing suspended solids and solid particles, membrane filtration technology is widely used to remove particles and colloidal substances, pathogenic microorganisms and a part of NOM (natural organic matter) ...
