Effect of Riverbank on River Self-purification of Organic Contaminants
摘要
Abstract
OnthebasisofriverwaterqualitymodelNo.1(RWQM1),accordingtothemechanismofriverself-purificationcapacityaffectedbyriverbank,asimplifiedRWQM1(S-RWQM1)isestablishedtosimulatethebiochemical reactionprocessoforganiccontaminantdegradationinriversandanalyzethecorrelationbetweenriverbank,contentand metabolismstatusofmicrobialinwater,organiccontaminantdegradationratioandmodelparameters.Sensitivityanalysis isperformedtothekineticparametersofS-RWQM1.ThesimulationresultsshowthatwithregardtothecomponentsofCODCr suchasbiodegradabledissolvedorganicmatterSSandheterotrophicbacteriumXH,theheterotrophicaerobicgrowthrate constant k affects the content of S and the heterotrophic aerobic endogenous respiration rate constant kgro,H,aer,T0 S resp,H,aer,T0 affectsthecontentofXHsignificantly.Resultsfromcorrelationanalysisindicatethatthecorrelationcoefficientsof modelparameterk andlipidphosphoruscontentofmicrobial,MK/UQvalue,andorganicmatterdegradabilityaffectedgro,H,aer,T0 byceramicglaze,permeablebricksandpinepilesastheriverbankmaterialsare0.995, -0.904and0.988respectively.
