Technical Field

[0001] The present invention relates to the technical field of industrial wastewater, and particularly relates to an industrial wastewater treatment equipment by the all-membrane method. Background Art

[0002] Industrial wastewater treatment is an indispensable part in modern industrial production. Especially in industries such as chemical engineering, pharmaceuticals, electroplating, etc., the efficient treatment of wastewater directly affects environmental protection and resource utilization. Its complexity is high and the types of pollutants are diverse (such as oil stains, heavy metals, suspended particles, etc.), and purification needs to be achieved through multiple processes. The all-membrane method (including membrane technologies such as RO, UF, MBR, NF, etc.) is widely used due to its high efficiency and environmental friendliness.

[0003] The existing all-membrane method treatment equipment still has the following problems: when initially treating larger particles, the uneven spraying of wastewater causes excessive local load on the filter element, rapid accumulation of particulate matter, reduction of filtration efficiency, frequent replacement of the filter element increases costs, and the wastewater delivery flow in some areas is relatively concentrated, while in other areas there may be almost no filtering effect, thus resulting in the insufficient utilization of the filtering capacity of the filter element, significant reduction of the filtration efficiency in local areas, and the pores of the filter element are limited, and the rapid accumulation of particulate matter will cause local pores to be completely blocked. Once the pores are blocked, the wastewater will not be able to pass through this area, resulting in a decrease in filtration efficiency. Summary of the Invention

The first cylinder 80 drives the first clamping plate 82 and the second clamping plate 86 to clamp the new filter element 6 and move to the position where it is docked with the docking block 53 in the processing box 1. Set the electric push rod 51. The output end of the electric push rod 51 drives the docking column 52 and the moving plate 54 to move along the chutes on both sides of the rotating cylinder 50 and drives the docking block 53 to complete the docking with the groove of the new filter element 6, thereby completing the replacement of the filter element 6;

[0082] Make the filter element 6 easier to replace, avoid the traditional manual replacement that is easy to be contaminated with a large amount of oil and impurities, make the replacement of the filter element 6 more convenient and efficient, and can effectively reduce the direct contact with the waste filter element 6.
