Embodiment 1

[0045] Such as figure 1 As shown, the present invention provides a regenerative circulation filtration system, at least comprising a regulating tank 7, a first intermediate pool 8, an activated carbon input unit 11, a V-shaped filter tank 14, a second intermediate pool 15, a waste hopper 16, and an activated carbon regeneration unit 17 And several washing devices 100 connected in series. Specifically, the regulating tank 7 is used for pretreatment of influent water such as flocculation and homogeneity. The downstream of the adjustment tank is connected to the first intermediate water tank 8, so that the primary water produced by the pretreatment of the adjustment tank 7 can enter the first intermediate water tank 8 for temporary storage. The downstream of the first intermediate pool 8 is connected with several washing devices connected in series. For example, the regenerative circulating filter system of the present invention includes four washers. The drain pipe 508 of the...

Embodiment 2

[0050] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0051] Such as figure 2 As shown, the activated carbon regeneration unit 17 at least includes a housing 21 , a lifting mechanism 22 , an aeration mechanism 23 , a first water inlet 24 , an aeration part 25 and a drainage part 26 . The shape of the housing 21 is defined by a columnar shape. A first water inlet 24 is provided on the outer wall of the casing 21, and the first water inlet 24 is used for introducing fluid-like activated carbon into the casing.

Abstract

The invention relates to a regenerative circulating filtration system. The regenerative circulating filtration system at least comprises two or more material washing devices and an activated carbon regeneration unit which are communicated in sequence; inlet water flows through the material washing devices in sequence to be subjected to circulating filtration treatment, activated carbon flows through the material washing devices in sequence and enters the activated carbon regeneration unit to be regenerated, and the activated carbon regeneration unit at least comprises an aeration part in a shell; the aeration part is configured to conduct first-stage regeneration treatment on the activated carbon in the following modes that the aeration part forms multiple gaps for receiving the activatedcarbon according to a filter material stacking mode, and the activated carbon moves in the gaps to be regenerated.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a regenerative circulation filter system. Background technique [0002] Activated carbon adsorption technology is widely used in urban water supply treatment, sewage and wastewater treatment, food processing, chemical production, hydrometallurgy and other technical fields. Due to its excellent adsorption effect on organic matter and heavy metals and other pollutants in the water system, the annual use and consumption of activated carbon is very huge. Due to the high price of activated carbon, regeneration should be considered after the adsorption of granular activated carbon is saturated to restore the adsorption capacity. Traditional regeneration methods, such as thermal regeneration methods, must take out the activated carbon, dehydrate it, and heat it to above 600°C after drying, so that all the adsorbed organic matter can be decomposed into CO 2 , N 2 、H ...
