Abstract： Industrial parks generatealarge amountof heavymetal micro-polluted wastewater，posing a potential threatto the ecological environment.The heavy metal micro-polution wastewater treatment technology is designed for industrial parks basedonmembrane bio-reactor，utilizing microbial communities onbiofilms toadsorb，transform，andremove heavy metals from wastewater.Microorganisms purify wastewaterbyconverting heavy metal ions into insoluble compounds through metabolicactivities.The experimental results indicatethatthe membrane permeabilityof the havy metalmicro-polluted wastewater treatment technology meets the expected requirements and can treat heavy metal micro-poluted wastewater andimprove water treatmenteficiency.The membranecleaning eficiencyishigh，effectivelyavoidingtheprecipitationof calcium ions caused by high temperature，and providing an efective means for biodegradation.
