Problems solved by technology

[0003] Although the treatment effect of the upward flow activated carbon adsorption pool is good, due to the lack of a suitable pool structure, the difficulty of uniform water distribution and the high cost of the filter, there are many restrictions in the actual layout of the water plant, and the pool type of the subsequent treatment process poor composition

Embodiment 1

[0030] The double filter tank includes a group of carbon tanks and sand tanks arranged side by side. The carbon tank and the sand tank are separated by a partition wall. The water tank, the water outlet of the sump corresponds to the opening position of the partition wall, and the drainage device corresponding to the opening position of the partition wall is provided in the sand tank. The height of the drainage device is lower than the height of the sump, and the sump and the drainage device are connected by a water guide .

[0031] Specifically, one side of the charcoal pool is provided with a water inlet channel, and the side of the water inlet channel is provided with a water inlet channel. The bottom of the water inlet channel is connected with a single grid water inlet pipe. The carbon pool water distribution and gas distribution channel under the carbon pool is connected with the carbon pool, and one side of the carbon pool water distribution and gas distribution channel...

Embodiment 2

[0035] The invention provides a carbon-sand integrated double filter tank, which can be provided with multiple groups of one-to-one corresponding carbon tanks and sand tanks, and each group of filter tanks is a combination tank of an upward flow activated carbon adsorption tank and a sand filter tank Type, the first half of the carbon-sand integrated double filter tank is a carbon tank with water inflow from the bottom and water out from the upper part, and the second half is a sand tank with water in and out from the top. The carbon-sand integrated double filter does not have a central channel, and the effective filtration area of ​​the pool is larger, the layout is reasonable and compact, the floor area is small, the investment is small, and the combination with other water purification structures is more flexible.

[0036] Specifically, the double filter tank includes a group of carbon tanks and sand tanks arranged side by side. The carbon tank and the sand tank are separate...

Embodiment 3

[0040] Such as figure 1 and figure 2Shown is an embodiment of a carbon-sand integrated double-combined filter tank in which the sand tank adopts continuous flushing and drainage tanks for continuous drainage, including at least one carbon-sand integrated double-combined filter tank, which is composed of an upward flow activated carbon adsorption tank 22 and a sand tank 23. Two into one, the first half is the charcoal pond 22, the second half is the sand pond 23, the partition wall between the charcoal pond 22 and the sand pond 23 is separated, only through the partition wall opening corresponding to the carbon pond water collection finger groove 9 and the sand Pool 23 Unicom. Water collection finger groove 9 is set in charcoal pond 22, drainage groove 13 is arranged in sand pond 23, and drainage groove 13 corresponds to charcoal pond water collection groove 9 one by one, and groove width is the same, and drainage groove 13 top is lower than water collection groove 9 bottoms....

Abstract

The invention relates to a carbon-sand double-spliced filter tank which comprises at least one group of carbon tank and sand tank which are arranged in parallel, the carbon tank and the sand tank areisolated through a partition wall, partition wall openings are formed in the partition wall, a plurality of water collecting tanks penetrating through the carbon tank are arranged in the carbon tank,and water outlets of the water collecting tanks correspond to the partition wall openings in position. Drainage devices corresponding to the positions of the partition wall openings are arranged in the sand pool, the drainage devices are lower than the water collecting tanks, and the water collecting tanks are connected with the drainage devices through water guide pipes. In the implementation process, the integrated double-spliced filter tank is not provided with a central channel, the effective filter area of the tank type is large, the arrangement is reasonable and compact, and the occupiedarea is small. Meanwhile, an upward flow activated carbon adsorption tank and the sand filter tank are combined in one tank, the structure is simple, pipelines are few, and water loss is small.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a carbon-sand double filter tank, especially a carbon-sand without a central canal used in advanced treatment of water supply plants, treatment of sewage tanks and special water treatment One double filter. Background technique [0002] At present, the ozone biological activated carbon process and sand filter process are mostly used in the advanced treatment of waterworks, sewage treatment and special water treatment. The ozone biological activated carbon process has a better removal rate for natural organic matter and ammonia nitrogen in raw water. Sand filtration The pool process has a better removal rate for particulate matter in water. There are two forms of biological activated carbon adsorption pools in the ozone biological activated carbon process: downflow fixed bed and upflow fluidized bed. It is more common to use a downward-flowing fixed-bed biological activa...
