Regenerating method of active carbon filter

Abstract

The invention provides a regenerating method of an active carbon filter, which comprises the following steps of: (1), discharge of water: controlling a liquid level to be 200-400mm above an active carbon filtering layer; (2), air scrubbing: removing pollutants on surfaces of active carbon particles; (3), backwashing: removing the pollutants on the surfaces of the active carbon particles through backwashing; (4) discharge of water: discharging all water in equipment; (5), drying of active carbons: controlling the temperature between 115 DEG C and 120 DEG C, and blowing pollutant scraps and powdery active carbon out of the active carbon filter; (6), rinsing of the active carbon: rinsing and cleaning the pollutant scraps, dust and the powdery active carbon; and (7), positive rinsing. When the method provided by the invention is adopted, acid and alkaline wastewater is not produced, and the requirement for environment friendliness is met; as dry high-temperature hot air is adopted, water in the active carbon particles can be boiled and evaporated, an inner pressure can be produced, and micro capillary holes of the active carbon can be unblocked and recovered to restore the adsorption function; moreover, the dry high-temperature hot air can be used for killing organic lives and blowing the organic lives out of the equipment to realize complete cleaning.

Description

technical field [0001] The invention relates to a regeneration method of an activated carbon filter. technical background [0002] At present, activated carbon filters have a wide range of uses and can be widely used in various industries, such as electric power, metallurgy, steel, petroleum, food, tap water, etc., and can be used to remove organic matter, colloidal substances, decolorize, and adsorb certain chemical elements, such as: fluorine , Chlorine, Bromine, Iodine and Iron etc. However, the adsorption capacity of activated carbon is limited. After a period of time, it will fail, lose its proper adsorption, and even become a new source of pollution, breeding new life such as new organic matter mucous membranes and nematodes. Sometimes it rots and smells, so it must be cleaned. and resurrection. [0003] Since the large-scale activated carbon filter was put into operation, the cleaning and regeneration process has not been effectively solved. In the past, professiona...

Problems solved by technology

[0005] Aiming at the high cost of cleaning and regeneration of activated carbon filters in the prior art and the inability to effectively restore its adsorption function, the present invention provides a regeneration method for activated carbon filters. The regeneration method of the invention is simple and easy to operate and has no pollution It is environmentally friendly, and the cost is low, suitable for a wide range of applications
