Emergency Monitoring And Disposal Study Of Sudden Antimony Pollution In Water

Antimony is a common water pollutant,which has adverse effects on human health and ecological environment.In the event of a sudden water antimony pollution event,emergency monitoring and disposal is an important measure to ensure the safety of drinking water and reduce the impact of pollution.Sudden water body contamination emergency monitoring and disposal is the occurrence of sudden water body contamination events,timely water quality monitoring and assessment,take effective disposal measures to eliminate or reduce the pollution hazard process.This paper takes a sudden water antimony pollution event as a background case,and studies the laboratory small test experiment,emergency monitoring traceability and technology,and emergency disposal technology comparison,which provides an effective method and theoretical basis for the removal of antimony in water,and provides a reference for emergency monitoring and disposal of sudden water antimony pollution.In this paper,the effect and mechanism of polymerized ferric sulfate as coagulant to remove antimony in water were studied.Through small laboratory experiments,the operating conditions such as the dosage,p H and initial concentration of polymeric iron sulfate were optimized to obtain the best antimony removal scheme.80 mg/L of polymeric iron sulfate was chosen to remove 50 μg/L of Sb(III)and Sb(V)to 2.3 and 3.5 μg/L at p H=9.The effect of coexisting substances on the removal was explored by the RSM method.The effect of polymerized ferric sulfate on antimony interaction was analyzed,and the coagulation mechanism included electro-neutralization,co-precipitation and network capture.Emergency monitoring using the "uniform division method" to trace the source of pollution,the contaminated area cross-sectional distribution,analysis of monitoring screening,tracking and termination of data,to determine the emergency monitoring and analysis of antimony pollution method.Compare the emergency disposal technology process,removal efficiency and impact of dosing coagulation and small sewage treatment station,dosing coagulation can be chosen in the early stage,and small sewage treatment station can be used in the later stage.
