摘要
Abstract
[Objective]Introduce the commissioning and operation process of a fluoride wastewater treatment project in a photovoltaic industrial park,and focus on the commissioning situation of reducing the fluoride ion mass concentration in the wastewater from 8 mg/L to 1.5 mg/L.[Methods]In view of the water quality characteristics of the wastewater discharged in the photovoltaic industrial park,the commissioning is carried out in two steps:biochemical commissioning and physical and chemical commissioning.After the biochemical commissioning,the physical and chemical debugging is further carried out for CODCr and fluoride ions that cannot be removed through the biochemical process.The key point of the commissioning process is to remove the fluoride ions in the wastewater by physical and chemical means,and to obtain better fluoride ion removal effect and lower removal cost by regulating the dosage and adjusting the dosage point.[Results]After the completion of the biochemical commissioning,the initial use in the biochemical pool front coagulation sedimentation tank step except fluorine treatment measures,found the need to add large dosage,agent add the amount of sludge is too large,and large amount of sludge cannot fully precipitation and overflow to the subsequent biochemical process section,sludge fluoride ion in the biochemical section will decomposition and back to the wastewater,which affect the effect of fluoride system,make fluoride ion in the subsequent treatment facilities.For this reason,the measure of adding agents step by step is adopted,and the agent injection is divided into two points:the front end coagulation sedimentation tank and the biochemical efficient sedimentation tank,and the fluoride sludge of the high efficiency sedimentation tank is returned to the front end to further play the role of fluoride removal,which effectively reduces the dosage of fluoride removal and stabilizes the fluoride ion index of the effluent water.[Conclusion]Through the commissioning of biochemical physical.关键词
