Embodiment Construction

[0024] Such as Figure 1 to Figure 3 As shown, the present invention provides a water treatment device combined with sand filter and ozone activated carbon. Wherein, the arrows in each figure indicate the direction of water flow.

[0025] In this embodiment, the water filtered by the sand filter is named primary filtered water.

[0026] In the first embodiment, if Figure 1 to Figure 3 As shown, it includes a first filter device, a second filter device and a backwash pump room 3, and the first filter device and the second filter device communicate with the backwash pump room 3 respectively.

[0027] Such as figure 1 As shown, the first filter device includes a first sand filter tank 11 , a first ozone contact tank 12 and a first activated carbon filter tank 13 . Wherein, the first sand filter 11 communicates with the first lifting pump room 15 through the catchment channel 4 , and the first sand filter 11 communicates with the backwash pump room 3 through the backwash pipe...

Abstract

The invention discloses a water treatment device with combination of sand filtration and ozonation and activated carbon. The water treatment device at least comprises a first filtering device, a second filtering device and a backwashing pump house, wherein the first filtering device and the second filtering device are respectively communicated with the backwashing pump house; the first filtering device consists of a first sand filtration pool, a first lift pump house, a first ozone contact pool and a first activated carbon filtration pool, the first sand filtration pool is communicated with the first lift pump house by virtue of a water collecting channel and is communicated with the backwashing pump house by virtue of a backwashing pipe gallery, and the first ozone contact pool which is communicated with the first activated carbon filtration pool is respectively communicated with the first lift pump house and the backwashing pump house by virtue of exposed pipelines. According to the water treatment device disclosed by the invention, as the two sets of filtering device share one backwashing pump house, and the sand filtration pool and the ozonation and activated carbon filtration pool are used in a combination mode, the water treatment device has the beneficial effects of good treatment effect, compact structure and long service life of equipment.

Description

technical field [0001] The invention relates to the technical field of water supply treatment, in particular to a water treatment device combined with sand filter and ozone activated carbon. Background technique [0002] Due to the deterioration of drinking water sources, the requirements for advanced water treatment technology are also getting higher and higher. Among the various advanced water quality treatment processes commonly used at present, the ozone activated carbon combined process is one of the more mature treatment processes at present. [0003] However, due to the large head loss when using the ozone activated carbon combined process to treat water, and a set of ozone activated carbon combined equipment must be equipped with a set of backwashing equipment, and the backwashing equipment occupies a large area and consumes a lot of energy. The rate is low, which greatly increases the cost of water treatment. [0004] Therefore, those skilled in the art urgently n...
