Abstract

The invention discloses a nanofiltration industrial waste water integrated treatment system. The system comprises a barrel. A filtering mechanism comprises a mounting top plate, a filter drum and a mounting bottom plate. The filter drum is arranged between the mounting top plate and the mounting bottom plate. The filter drum comprises multiple struts and multiple nanofiltration membrane assemblies. One axial ends of the struts are fixed to the mounting bottom plate, and the other axial ends of the struts are detachably connected to the lower plate surface of the mounting top plate. Mounting grooves are formed in the side walls of the struts in the axial direction, and the nanofiltration membrane assemblies are clamped into the mounting grooves of two adjacent struts through clamping platesto be fixed. The mounting top plate is clamped at the open end of the barrel, and the filter drum is arranged in the barrel. A stirring mechanism comprises a mounting base plate and a stirring shaft,the stirring shaft penetrates through the mounting top plate in a clearance fit mode to stretch into the filter drum, and stirring blades are arranged on the shaft section, located in the filter drum, of the stirring shaft. The filtering mechanism and the stirring mechanism are arranged in the barrel at the same time and act jointly, blockage in the filter drum can be effectively avoided, and thefiltering effect is further improved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a nanofiltration industrial sewage integrated treatment system. Background technique [0002] In the existing sewage treatment equipment, the commonly used sewage filter device is a sand filter, the volume of the sand filter is large, and the filter element of the filter is easy to block and harden, resulting in poor filtering effect, and a large amount of water is required after hardening Clean water is used for backwashing, and the sewage generated by backwashing needs to be filtered again, resulting in low sewage treatment efficiency of sewage treatment equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing filter element is easy to block and harden, and the filtering effect is not good. The purpose is to provide an integrated treatment system for nanofiltration industrial sewage. Prevent blockage in the fi...
