Abstract：A certain enterprise produces 100m3 of sulfuric acid wastewater containing acid，zinc，fluorine，chlorine and othersubstanceseveryday，andthesulfuricacid wastewaterresiduegeneratedbytheoriginaltreatmentmethoddoesnot meetthe salesandutilizationconditions，resulting incostburdenandpolutionhazards.Adoptingthetechnologyof“first stageneutralizationof limestone powder to produce gypsumfrom sulfuricacid-second stage neutralizationand precipitation oflime torecover zincmetal"，thesulfuricacid wastewater treatmentsystemistransformed forresourceutilization.The technicalprinciples，process，ndainrenovationcontentsoftherenvationareelaborated，andthebenefitsaretiated. The results showthattherenovation projecthasaninvestmentof7644OOyuan，anannualincome increaseof1.02millon yuan，aninvestmentrecoverycycleof1year，ndcanreducetheoutputof1Oootofwasteresidueperyear，realizingthe resource utilization of sulfuric acid wastewater，which has significant economicand environmental benefits.
