Sewage treatment filter

Abstract

The invention is suitable for the technical field of sewage treatment, and provides a sewage treatment filter. The sewage treatment filter comprises a rack as well as a filter structure and a pressingstructure which are sequentially connected onto the rack, wherein the rack comprises two beams which are arranged in parallel; the filter structure comprises an adsorption separation bag and a plurality of filter plates; the adsorption separation bag comprises at least two filter layers, and every two adjacent filter layers form a sealed area which is of a ring-shaped closed structure; the ring-shaped closed structure is enclosed to form a filling area; the sandwich layer of the filling area is filled with an adsorption material; a fixed area is formed on the outer part of the ring-shaped closed structure; and the pressing structure comprises a piston rod, the two ends of the piston rod are separately connected with a pressing plate and a drive structure, and the drive structure is electrically connected with a control cabinet. The sewage treatment filter can integrate solid-liquid separation and harmful ion removal, further has the functions of adsorbing and filtering, is convenientto clear, and is low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment filter. Background technique [0002] In the subsequent treatment process of industrial sewage and domestic sewage, sewage separation is completed by different equipment and processes: solid-liquid separation uses filter presses, separators, etc.; harmful ions are removed using degreasing tanks and activated carbon adsorption tanks, tanks Oil-absorbing fluffy balls, activated carbon, and quartz sand of different particle sizes are installed in the tank, and different equipment and processes are used for sewage treatment, which increases costs and increases workload. During the removal of harmful ions, after the degreasing tank and the adsorption tank are saturated, they need to manually enter the tank for cleaning. Due to the serious calcification and scaling of calcium and magnesium ions in the industrial sewage, and the narrow space of the degreasing...

AI Technical Summary

Problems solved by technology

During the removal of harmful ions, after the oil removal tank and the adsorption tank are saturated, they need to manually enter the tank for cleaning. Due to the serious calcification and scaling of calcium and magnesium ions in industrial sewage, and the narrow space of the oil removal tank and adsorption tank, resulting in Manual cleaning is difficult and labor-intensive. As time goes on, there will be more garbage deposited in the oil removal tank and adsorption tank, which will affect the efficiency of sewage treatment and cause the work site to be dirty, messy and poor.

[0003] At present, the treatment of industrial sewage and domestic sewage requires a filter that integrates solid-liquid separation and removal of harmful ions in the same equipment, and is easy to clean. However, there are few reports on related research

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
