Filter screen for removing electric energy from sewage

Abstract

The invention discloses a filter screen for removing electric energy from sewage. The filter screen comprises a cloth bag, wherein a nylon rope is stitched on the cloth bag, an iron spherical shell is arranged in the cloth bag, a through hole is formed in the iron spherical shell, the diameter of the through hole is 1 to 2 mm, an inner cavity of the iron spherical shell is filled with natural manganese ores, the diameter of the natural manganese ores is 2 to 4 mm, the nylon rope is tied to a cross rod, the cross rod is welded on a first stainless steel rectangular frame, fixed plates are respectively installed on four corners of the outer side of the first stainless steel rectangular frame, threaded holes are formed in the fixed plates, and the fixed plates which are installed on the four corners of the first stainless steel rectangular frame are connected with fixed plates which are installed on four corners of a second stainless steel rectangular frame by bolts. The filter screen for removing electric energy from sewage has the advantages of simple structure, smart design, low cost and high capability of removing electric energy from water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a filter net for removing electric energy in sewage. Background technique [0002] With the development of society, the environment is becoming more and more polluted, especially the serious pollution of water resources. When treating sewage, sewage cannot be discharged directly into rivers and lakes, but the sewage should be purified first and then discharged into nature. . In daily life, the sewage used by people needs to be discharged through the sewer. If it is not treated, the impurities in the sewage will block the sewer, which will bring unnecessary troubles to people's life. [0003] When using sewer pipes to discharge domestic sewage, it is usually necessary to install a filter screen at the sewer port to prevent dirt from clogging the sewer. When these filter devices are in use, most of them can only filter out impurities in the water, but they cann...

Problems solved by technology

In daily life, the sewage used by people needs to be discharged through the sewer. If it is not treated, the impurities in the sewage will block the sewer, which will bring unnecessary troubles to people's life.

[0003] When using sewer pipes to discharge domestic sewage, it is usually necessary to install a filter screen at the sewer port to prevent dirt from clogging the sewer. When these filtering devices are in use, most of them can only filter out impurities in the water, but they cannot remove the electric energy in the water. The water containing electric energy flows into natural rivers, which will inevitably cause great pollution
