specific Embodiment approach 1

[0013] Specific implementation mode one: this implementation mode combines figure 1 with 2 The present invention is described in further detail:

[0014] Such as figure 1 As shown, the adsorption fluidized bed of the present invention comprises a water inlet 1, a water distribution area 2, a porous plate water distributor 3, a fluidized adsorption area 4, a liquid-solid separation area 6 and a water outlet 5; the water distribution area 2 mainly plays a role in water flow. The buffer function is a gradually expanding cylinder, the lower end is the water inlet 1, and the upper end is the porous plate water distributor 3. The lower end of the porous plate water distributor 3 is covered with a layer of filter mesh. The blue 7 is fixed, and the upper end of the porous plate water distributor 3 is connected with the fluidized adsorption area. The fluidized adsorption area 4 is a straight cylindrical cylinder with an adsorbent for adsorbing pollutants inside. The height of the ads...

specific Embodiment approach 2

[0019] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the adsorption fluidized bed is installed on a ship following the movement of the pollution mass, and the pollution mass is sucked into its water inlet by a pump, and the water after fluidized adsorption treatment is produced by The water outlet discharges back into the body of water.

[0020] In this embodiment, the fluidized bed with a height of 2m and a diameter of 0.5m treats water of 0.6 to 6.3m 3 / min, 1m 3 The water treatment time is 0.16~1.7min.

[0021] The above-mentioned adsorption fluidized bed technology was used to treat phenol in water, and granular activated carbon was used as the adsorbent. The results showed that when the influent flow rate was 9.8L / min, the particle size of activated carbon was 0.55-0.17mm, and the dosage was 800g, 15 Within minutes, the total amount of 3g, the concentration of 100mg / L phenol after treatment decreased to 4.8mg / L, and the ...

Abstract

The invention relates to an adsorption fluidized bed applied to the emergency treatment of sudden water pollution and a method for the emergency treatment of the sudden water pollution by using the same, belonging to the technical field of water environmental safety prevention and control emergency treatment. The adsorption fluidized bed comprises a water inlet (1), a water distribution zone (2), a fluidized adsorption zone (4), a liquid-solid separation zone (6) and a water outlet (5), wherein the lower end of the water distribution zone (2) is provided with the water inlet (1), the upper end of the water distribution zone (2) is connected with the fluidized adsorption zone (4), the liquid-solid separation zone (6) is arranged above the fluidized adsorption zone (4), and the water outlet (5) is arranged at the top of the liquid-solid separation zone (6). When a pollution clump is not fully dispersed, the adsorption fluidized bed is installed on a boat and is used for treating the pollution clump after a pump is used to suck the pollution clump into the adsorption fluidized bed. Alternatively, a scaffolding is installed at the front end of a check gate of a conveyance canal, the scaffolding is internally filled with an adsorption wall, the adsorption fluidized bed is installed on the waterward surface of the adsorption wall, and water is pumped into the fluidized bed by siphoning to be treated. The adsorption fluidized bed and the method has the advantages of simpleness for operation, high removal efficiency and large water flux.

Description

technical field [0001] The invention belongs to the technical field of emergency treatment of water environment safety prevention and control, and in particular relates to an adsorption fluidized bed applied to emergency treatment of sudden water pollution and a method for treating sewage by using it. Background technique [0002] In recent years, with the rapid and sustained economic and social development, major water pollution accidents have occurred frequently across the country. Sudden water pollution incidents refer to sudden incidents in which pollutants flow into rivers and lakes and cause water resources to be polluted due to economic and social activities and behaviors that violate water resources protection laws and regulations, as well as accidental factors or force majeure. Different from general water pollution, it has strong unpredictability and diversity, causing a large amount of pollutants to leak and discharge in a short period of time, causing serious har...
