Abstract
With the improvement of effluent quality standards,a sewage treatment plant in Heze city,Shandong province urgently needs to undergo upgrading and renovation.On the premise of not changing the current capacity of the biochemical reaction tank,the sewage treatment plant undergoes a deep upgrading transformation,using a combination process of"magnetic coagulation+ozone catalytic oxidation+aerated biological filter+rotary filter"to treat fluorine-containing wastewater,providing reference for the design of similar sewage treatment plants.The results show that the average concentrations of Chemical Oxygen Demand(COD),ammonia nitrogen(NH3-N),Total Phosphorus(TP),and fluoride in the effluent are less than 25,1,0.2,1.5 mg/L,respectively,and the water quality can stably meet the requirement of design standards.关键词
