Treatment equipment for removing heavy metal ions in industrial wastewater

Abstract

The embodiment of the invention discloses treatment equipment for removing heavy metal ions in industrial wastewater, the treatment equipment comprises a treatment tank and a mud gathering cover mounted on the side surface of the bottom of the treatment tank, a bearing plate is mounted in the treatment tank, and a film separating device is mounted on the upper surface of the bearing plate; the film separating device is provided with a sweeping mechanism used for cleaning a film surface, the bearing plate is provided with a plurality of funnel holes, the equipment is provided with the sweepingmechanism, the operation of sweeping a permeable film can be achieved, and in actual use, a user can drive a movable mounting frame to drive a stepped sweeping table to conduct lifting operation at regular time, so that the cleaning efficiency is improved. Due to the fact that a brushing and sweeping column is installed on the step sweeping table, sundries or attachments on the surface of the filmcan be brushed off, the sundries accumulated on the surface of the film are reduced, the permeation amount of the permeable film is not affected, and meanwhile the blowing column on the stepped sweeping table can blow the surface of the film. Therefore, the sweeping efficiency is improved, and the situation that the brushed attachments are attached to the film surface again can be avoided.

Description

technical field [0001] The embodiment of the present invention relates to the field of sewage treatment, in particular to a treatment device for removing heavy metal ions from industrial wastewater. Background technique [0002] The process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused is sewage treatment. During sewage treatment, some sewage contains heavy metal ions. In order to make the sewage meet the purification requirements, it will Membrane bioreactor is used for treatment, and membrane bioreactor is a new type of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. Most of the membranes used are reverse osmosis membranes, and reverse osmosis membranes are a kind of simulated biological The artificial semipermeable membrane with certain characteristics made of semipermeable membrane is the core component of reverse osmosis technolo...
