Circular super-efficiency shallow air flotation filter treatment equipment and treatment process thereof

Abstract

The invention relates to the technical field of water treatment, in particular to circular super-effect shallow air flotation filter treatment equipment and a treatment process thereof. The circular super-efficiency shallow air floatation filter treatment equipment comprises a filter pressing device and an air floatation biological filter for further purifying water filtered by the filter pressing device, wherein the filter pressing device comprises filter plates, a push plate assembly, a connecting rod assembly and a transmission assembly; there are even number of filter plates which are stacked and arranged in the left-right direction, and rollers are arranged on the front side and the rear side of the middle of each filter plate; the push plate assembly is used for pushing the filter plates to open; every two filter plates form a group in sequence from left to right, and each group of filter plates comprises a first filter plate positioned on the left side and a second filter plate positioned on the right side; the connecting rod assembly is configured to enable the second filter plate to be lifted upwards within a preset distance of rightward movement of the second filter plate; the transmission assembly enables the inner ends of the rollers of the first filter plate to move rightwards along with the second filter plate when the second filter plate is lifted upwards so that the rollers of the first filter plate are inclined, and the first filter plate is prevented from sliding rightwards along with the second filter plate under the adhesion of a filter cake.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a circular ultra-efficient shallow air flotation filter treatment equipment and a treatment process thereof. Background technique [0002] In order to reduce the impact of sewage on the environment, it is necessary to treat sewage to meet the water quality requirements for discharge into a water body or reuse, and sewage often contains more difficult-to-degrade organic matter, nitrogen and phosphorus, which can lead to eutrophication of water bodies. Soluble inorganic substances, etc. The existing air flotation filter equipment includes two-stage treatment. The first-stage treatment uses filtration to remove solid pollutants in water, and the second-stage treatment uses activated sludge method or biofilm method to treat soluble inorganic substances in water. In order to improve the filtration efficiency of the primary treatment, multiple filter plates are often used ...
