Tsev Kho Mob Tes no yog hais txog cov dej phwj tuaj los ntawm tsev kho mob uas muaj cov kab hlau, cov tshuaj tua kab mob organic, acids, thiab radiocactivity. Nws muaj cov yam ntxwv ntawm kev ua qias neeg txawv txawv, mob, thiab kab mob latent. Yog li tsis muaj kev kho mob, nws tuaj yeem dhau los ua txoj kev tseem ceeb rau kev kis mob ntawm cov kab mob thiab ib puag ncig. Yog li ntawd, kev tsim kho ntawm dej phwjcogHauv tsev kho mob tau dhau los ua tus yuam sij los daws cov teeb meem no.
1.Tsev kho mob lim dej thiab pretricate
Lub phiaj xwm lees txais cov dej phwj tuaj hauv tsev thiab dej nag ntws tawm, uas yog ua tau raws li cov dej ntws hauv nroog. Cov dej phwj dej thiab cov dej phwj tuaj hauv thaj chaw hauv plab, thiab tom qab ntawd cov tshuaj tua hluav taws xob nrog cov dej phwj tuaj rau hauv chaw da dej hauv thaj chaw dej phwj tuaj rau hauv chaw kho mob hauv tsev kho mob rau kev kho mob. Tom qab ntsib kev tso zis ntawm cov dej paug rau cov khoom noj kom zoo rau cov khoom kho mob, lawv tau tawm tsam kev kho cov dej phwj hauv nroog
Cov chav ua haujlwm tseem ceeb piav qhia ntawmdej phwjcog
① Daim phiaj daim phiaj yog nruab nrog ob txheej ntawm ntxhib thiab zoo nkauj, nrog sib txawv, nrog cov kab sib txawv thiab 10 hli nruab nrab ntawm cov kab sib dhos. Kev sib cuam tshuam cov khoom loj me me ntawm cov teeb meem uas tsis muaj teeb meem thiab xws li cov ntawv scraps (xws li cov ntawv scraps, khaub ncaws, lossis cov chav ua haujlwm tom qab. Thaum muab tso rau, kev sib tsoo yuav tsum tilted ntawm 60 ° kaum rau ntawm cov dej ntws taug qab los pab tshem cov seem ntawm cov seem. Txhawm rau tiv thaiv cov pipeline sedimentation thiab cov kev faib tawm ntawm cov tshuaj uas pom zoo, tus qauv yuav tsum tswj tus nqi dej phwj tuaj ua ntej thiab tom qab grating ntawm 0.6 m / s. Cov tshuaj sib txuam pom los ntawm kev sib tsoo yuav tsum tau tua hluav taws thaum tshem tawm thaum lub sijhawm tshem tawm vim muaj cov pathogens loj.
② Pas dej ua ke
Nws xwm ntawm tsev kho mob tawm mus txiav txim qhov tsis zoo ntawm cov dej tuaj ntawm cov chaw dej phwj tuaj. Yog li ntawd, lub tank regulating tau teeb tsa homogenize qhov zoo thiab ntau ntawm cov kev cuam tshuam ntawm kev cuam tshuam ntawm kev kho cov khoom siv rau kev kho cov khoom tom ntej. Nyob rau tib lub sijhawm, teeb tsa kev sib tsoo cov yeeb nkab rau lub pas nrig sib tsoo. Kev siv tshuab hluav taws xob tau muab ntsia rau hauv lub tank regulating kom tiv thaiv cov sedimentation ntawm kev tshem tawm cov lus thiab txhim kho biodegradity ntawm wantewater.
HyBoxic pas dej aerobic
Anoxic aerobic tank yog cov txheej txheem tseem ceeb ntawm cov dej phwj nqa. Nws qhov zoo dua yog tias ntxiv rau kev ua tsis taus cov pa organic, nws tseem muaj qee txoj haujlwm ntawm nitrogen thiab phosphorus tshem tawm. Seem A / O txuas txuas rau ntu pem hauv ntej thiab seem tom qab sab hauv, nrog ib ntu tsis tshaj 0.2 mg / l thiab o-4 mg / l.
Nyob rau hauv lub anoxic theem, heterotrophic birothze txwv tsis pub muaj kuab paug, ua rau cov organic accicic, ua rau cov organic accicic, ua rau cov orgromolecular organic teeb meem mus rau hauv molecule cov teeb meem. Cov organic insoluble muaj teeb meem rau hauv soluble organic teeb meem. Thaum cov khoom lag luam ntawm anaerobic hydrolysis nkag mus rau Aerobic Tank rau Aerobic kev kho mob, lub biodegradity ntawm cov dej phwj tuaj thiab kev ua haujlwm ntawm kev tawm ntawm cov pa tau txhim kho.
Hauv tshooj anoxic, Heterotrophic cov kab mob muaj kuab lom xws li cov protein thiab cov rog (n ntawm cov amino acid) kom free ammonia (NH3, NH4 +). Nyob rau hauv cov pa oxygen txaus, nitricification ntawm autotrophic cov kab mob nhgizes NH3-N (NH4 +) rau NO3 -, thiab rov qab los pas dej los ntawm kev tswj hwm dej hiav txwv. Nyob rau hauv anoxic tej yam kev mob, tus nqi tsis kam lees ntawm Heterotrophic cov kab mob Txo Nitrogen (N2) kom ua tiav lub voj voog ntawm C, N, thiab paub tias muaj kev phom sij lim hiam tsis muaj zog.
④ Cov tshuaj tua kab mob kub
Lub taub lim effluent nkag mus rau hauv lub tshuaj tua kab mob kom tswj tau lub sijhawm sib chwv thiab cov tshuaj tua kab mob uas ua rau cov tshuaj tua kab mob zoo rau cov kab mob. Lub effluent yog tso rau hauv lub nroog pipeline network. Raws li cov qauv "dej paug tawm ntawm cov chaw ntxuav cov tsev kho mob", lub sijhawm sib tham ntawm cov tsev kho mob kab mob kis tau los ntawm cov tsev kho mob sib kis tau tsis tsawg tshaj li 1.0 teev.
