(3)单位时间 有机物质输入总量(mass of TOC added over time in input stream) = (加仑/分钟)Q • 毫克/加仑([TOC]s)
(4) mass of TOC removed over time in output stream = Q•[TOC]r
(5) Q•[TOC]s = Q•[TOC]r + depletion
(6) amount of TOC in the reservoir = Vr•[TOC]r
(7) depletion = Vr•d[TOC]r/dt
(8) Vr•d[TOC]r/dt = Q•([TOC]s - [TOC]r), where
(9) Vs•d[TOC]s/dt = Q•([TOC]r - [TOC]s) + removal
(10) TOC + bubbles → TOC•bubbles
(11) amount of TOC in the active water volume of the skimmer = Vs•[TOC]s
(12) rate of TOC removal by the bubbles ∝ -Vs•[TOC]s
(13) rate of TOC removal by the bubbles = -k•Vs•[TOC]s
(14) Vs•d[TOC]s/dt = Q•([TOC]r - [TOC]s) - Vs•k•[TOC]s
(15) (Vs/Vr)•d[TOC]s/dτ = [TOC]r - [TOC]s - Vs•k•[TOC]s/Q
(16) 0 = [TOC]t - [TOC]s - k•[TOC]s•Vs/Q, or
(17) [TOC]s = [TOC]r/(1 + k•Vs/Q)
(18) d[TOC]r/dt = (Q/Vr)•([TOC]r/(1 + k•Vs/Q) - [TOC]r)
(19) d[TOC]r/[TOC]r = -[k•Q/(Vr•(k + Q/Vs))]•dt,
(20) Ln([TOC]r/[TOC]0) = -[k•Q/(Vr•(k + Q/Vs))]•t |
