Novel aeration filtering tank

Abstract

The invention discloses a novel aeration filtering tank, which is provided with a filtering tank (1), wherein a cover plate (2) is arranged on the filtering tank (1), and is arranged on the upper surface of the filtering tank (1), an aerator (3) is arranged on the cover plate (2) of the filtering tank (1), and extends into the filtering tank (1), a surrounding baffle (4) is arranged beside the filtering tank (1) and surrounds the outer side of the cover plate (2), and a support frame is arranged on the surrounding baffle (4). According to the invention, by arranging the aeratorin the filteringtank, the efficient aeration can be carried out in the filtering tank, so that the flowability of the gas in the filtering tank can be improved, and the filtering tank is safe to use.

Description

technical field [0001] The invention relates to a filter tank, in particular to a novel aeration filter tank. Background technique [0002] The filter is a commonly used water treatment equipment for civil water supply, industrial water supply, wastewater treatment, environmental engineering, etc. It relies on the interception, adsorption, and precipitation of the filter material to filter the water. The impurity components are removed by the filter material adsorption or gap barrier, making the water clean. After the filter has been in operation for a period of time, the space for containing dirt between the filter layers gradually decreases, the head loss of the filtered water increases, and the filtered water becomes less and less, which reduces the filtering effect; or the quality of the effluent water becomes poor, and the filter fails. Rinse to remove the dirt deposited on the filter material, restore the working ability of the filter material, and ensure the normal o...
