Problems solved by technology

[0003] Although the treatment effect of the upward flow activated carbon filter 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 not many large-scale application examples in China at present, and the large-scale development of a single pool is limited.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0025] Such as figure 2 Shown, a kind of upflow activated carbon filter comprises a double-layer central channel 18 and an activated carbon filter layer 10; the double-layer central channel 18 is positioned at the center of the upward-flow activated carbon filter, and the double-layer central channel 18 includes the lower floor inlet channel 6 And the upper floor outlet channel 12, the bottom of the lower floor inlet channel 6 sidewalls is provided with distribution water holes 7, the activated carbon filter layer 10 is distribute...

Abstract

The invention provides an upward flow active carbon filter tank suitable for water plant deep treatment, sewage plant treatment, and special water treatment. The upward flow active carbon filter tank comprises a double-layer central canal and active carbon filter layers. The double-layer central canal is positioned on the center of the upward flow active carbon filter tank. The double-layer central canal comprises a lower-layer water inlet canal, an upper-layer water outlet canal, and a middle baffle. The middle baffle separates the lower-layer water inlet canal and the upper-layer water outlet canal. Distribution water holes are arranged on the bottom ends of the two side walls of the lower-layer water inlet canal. The active carbon filter layers are distributed on two sides of the double-layer central canal. A water collection tank is distributed on the side wall of upper-layer water outlet canal. The water collection tank communicates with the active carbon filter layers and the upper-layer water outlet canal. One end of the upper-layer water outlet canal is connected with a water outlet overflow weir, and the other end is connected with a primary-filtered water discharge gate. According to a water treatment system comprising at least one of the upward flow active carbon filter tank, tank layout is reasonable and compact, structure is simple, cost is low, pipe line amount is low, and land occupation is low. With the tank, a problem of the limitation in large-scale single-tank of current upward flow active carbon filter tank in our nation is solved.

Description

technical field [0001] The invention relates to the field of water supply treatment, in particular to an upward flow activated carbon filter used for advanced treatment of water supply plants, treatment of sewage plants and special water treatment. Background technique [0002] At present, the ozone biological activated carbon process is widely 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. The filtration form of the biological activated carbon filter in the ozone biological activated carbon process has two methods: downflow fixed bed filtration and upflow fluidized filtration. Among them, the biological activated carbon filter with downward flow fixed bed filtration is more common, but there are many problems in the traditional downward flow fixed bed filtration with biological activated carbon fil...
