Wastewater advanced treatment reaction module and water treatment reactor

Abstract

The invention discloses a wastewater advanced treatment reaction module and a water treatment reactor, the wastewater advanced treatment reaction module comprises two rectangular pipes, a three-dimensional drainage net, a filter screen, a reaction filler and a drainage pipe, the two rectangular pipes are arranged on two sides of the drainage pipe, the rectangular pipes and the drainage pipe enclose to form a water purification cavity, a drainage hole is formed in one side, close to the water purification cavity, of the drainage pipe, a water inlet hole is formed in the pipe wall of the rectangular pipe and communicated with the water purification cavity, the three-dimensional drainage net is arranged on the inner wall of the rectangular pipe and covers the water inlet hole, the filter netis arranged between the three-dimensional drainage net and the reaction filler, and the water treatment reactor comprises at least one reaction module. The filter screen is reinforced by the perforated rectangular pipe and the three-dimensional drainage net, so that the filter efficiency of contact reaction is prevented from being influenced by filler layer sinking and upper vacancy caused by deformation of the filter screen, the contact surface of the filter screen and sewage and the water distribution uniformity on the filter section are increased through the three-dimensional drainage net,and the filter efficiency of the wastewater advanced treatment reaction module is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a wastewater advanced treatment reaction module and a water treatment reactor. Background technique [0002] Filtration and adsorption Sewage treatment equipment mostly adopts vertical (upward flow, downward flow) water flow mode. Under water pressure, sewage passes through the adsorption and filtration of fillers to remove suspended solids and heavy metal ions in sewage. The vertical water flow packing adsorption and filtration method is prone to blockage of the initial packing, large head loss, low sewage treatment efficiency, and inconvenient replacement of the packing after blockage. In order to prevent the failure of the overall packing layer caused by the blockage of the surface packing, the prior art discloses a contact reaction sheet for water treatment, including: a water-permeable layer, a packing layer, an outer frame, and a water outlet. There are two packing ...
