Filtering system and filtering method

Abstract

The invention relates to the field of filtrating and purification, in particular to a filtrating system which comprises a filtrating device and is characterized in that the filtrating device is arranged to be a filtrating tower, a first water inlet is formed in the top of the filtrating tower, a first water outlet is formed in the bottom of the filtrating tower, and a filtrating component is arranged in the filtrating tower; and the filtering component and the filtering tower are detachable, the filtering component is sequentially provided with activated carbon, quartz sand, an anthracite filtering material and a filtering cotton core from top to bottom, one side wall of the filtering tower is provided with an opening and closing door, the opening and closing door is hinged to the filtering tower, and the side, away from the filtering tower, of the opening and closing door is provided with a handle. The handle is welded to the opening and closing door, and a rubber sealing ring is arranged on the side, close to the filtering tower, of the opening and closing door.

Description

technical field [0001] The invention relates to the field of filtration and purification, in particular to a filtration system and a filtration method. Background technique [0002] The current direct discharge of sewage is easy to pollute the environment, does not conform to the current environmental protection concept, and is unsustainable. Although the current filtration system is getting worse, there are still the following unsatisfactory points: [0003] 1. At present, the filter components in the filter tower cannot be disassembled; [0004] 2. At present, the cotton core in the filter member is easy to shrink and become soft after being soaked in water for a long time, which is inconvenient for subsequent use, affects the filtering effect, and increases the working cost at the same time; [0005] 3. At present, there is no precipitation port in the chemical purification tower, which is inconvenient to put precipitation reagents, which affects the work efficiency of t...

[0002] The current direct discharge of sewage is easy to pollute the environment, does not conform to the current environmental protection concept, and is unsustainable. Although the current filtration system is getting worse, there are still the following unsatisfactory points:

[0003] 1. At present, the filter components in the filter tower cannot be disassembled;

[0004] 2. At present, the cotton core in the filter member is easy to shrink and become soft after being soaked in water for a long time, which is inconvenient for subsequent use, affects the filtering effect, and increases the working cost at the same time;

[0005] 3. At present, there is no precipitation port in the chemical purification tower, which is inconvenient to put precipitation reagents, which affects the work efficiency of the staff;

[0006] 4. At present, there is no temperature adjustment device in the chemical purification tower, and the precipitation time will be longer, which will affect the work efficiency;

[0007] 5. At present, there is no concentration detector in the chemical purification tower, which cannot realize the automatic injection of precipitant, which increases the workload of the staff. At the same time, the content of added precipitant cannot be guaranteed, which affects the quality of precipitation
