Ukujonga ngaphezulu kwamanzi amdaka ikakhulu kuvela kwiinkqubo ezimbini zemveliso zokutywina kunye nokuhamba kwimveliso yepapermicking. Ukutsalwa kukwahlula iintsinga kwizinto eziluhlaza, zenze ipulp, emva koko uyilile. Le nkqubo iza kuvelisa isixa esikhulu samanzi amdaka epeyinti; I-papermarmermang kukuyila, ubume, cinezela, kwaye yome i-pulp ukwenza iphepha. Le nkqubo ikwathambeka ukuvelisa amanzi amdaka amaninzi. Amanzi aphambili aveliswayo kwinkqubo yokutywina bubumnyama utywala kunye notywala obomvu, kunye nepakethi ikakhulu ivelisa amanzi amhlophe.
AMANQAKU 1 AMANQAKU E-1. Ixabiso elikhulu lamanzi amdaka.2. Amanzi amdaka aqukethe isixa esikhulu seenyibilikisi ezinqunyanyisiweyo, ikakhulu i-inki, i-fiber, ifilitha kunye nokongezwa.3. I-SS, i-COD, i-BOD kunye nabanye abangcolisekileyo kumanzi amdaka baphakame, umxholo we-CoD uphezulu kune-BOD, kwaye umbala ubumnyama.
Isicwangciso sonyango kunye nesisombululo sengxaki.1. Indlela yonyango Indlela yonyango yangoku ikakhulu isebenzisa i-Anaerobic, i-aerobic, i-Inder kunye neKhemikhali yePhekami yeNkcazo yokuHamba.
Treatment process and flow: After the wastewater enters the wastewater treatment system, it first passes through the trash rack to remove larger debris, enters the grid pool for equalization, enters the coagulation tank, and produces a coagulation reaction by adding polyaluminum chloride and polyacrylamide. Emva kokungena kwifloti, i-SS kunye nenxalenye ye-BOD kunye ne-CoD kumanzi amdaka asuswa. Amanzi amdaka angena ndawo ingena kwi-Anaerobic kunye ne-Aerobic Aechemical Deachemical Deachemical Deachemical Deachemical ukuze ususe uninzi lwe-BOD kunye ne-cod emanzini. Emva kwetanki yendlela yesibini, i-COD kunye ne-chromatity yamanzi amdaka ayifezekisi imigangatho yokukhutshwa kwelizwe. I-Chemical Corcition isetyenziselwa ukufumana unyango oluphuculweyo ukuze amanzi amdaka afezekise imigangatho yokuphuma okanye akwazi ukufikelela kwimigangatho yokuphuma.
Iingxaki eziqhelekileyo kunye nezisombululo 1) cod igqitha umgangatho. Emva kokuba amanzi amdaka aphathwa ngonyango lwe-Aneerobic kunye ne-Aerobic Biochemical Biochemical, i-CoD yamanzi amdaka ayifezekisi imigangatho yokukhupha i-DOD. Yongeze emanzini ngendlela ethile kwaye usandul 'ukusabela kwimizuzu engama-30.
2) Zombini chromaticity kwaye i-COD igqitha kumgangatho emva kokuba amanzi amdaka aphathwa ngonyango lwe-anaerobic kunye ne-acherobic biochic biochimical, i-cod yamanzi amdaka ayifezekisi imigangatho yokukhupha. Isisombululo: Yongeza i-Decierizer ePhezulu yokuSebenzisa, xuba i-Decierizer ephezulu, kwaye ekugqibeleni sebenzisa i-polyacrysamlasside yeSolocyside yeShedCacysite kunye nokwahlukana okuqinileyo.
I-3) i-ammonia nitrogen Amanzi amdaka amdaka amdaka apmonian akanakuhlangabezana neemfuno zangoku. Isisombululo: Yongeza i-Ammonia nitrogen kwi-furver, i-tir okanye i-aecher kwaye idibanise, kwaye iphinde iphendule imizuzu emi-6. Kwimigugi yephepha, amanzi amdaka amdaka e-ammonia imalunga ne-40ppm, kunye nomgangatho wokukhutshwa kwe-ammoninian ye-Ammonian ungaphantsi kwe-15ppm, engakwazi ukuhlangabezana neemfuno zokukhutshwa kwezesimo ezimiselweyo kwiMigaqo yoKhuseleko lweNdalo emiselweyo.
Ukuqukumbela i-Popemermagung Ratenater Unyango lonyango kufuneka lugxile ekuphuculeni inqanaba lamanzi anokuphinda lusebenze, ukunciphisa amanzi amdaka, kwaye kwangaxeshanye, kufanele ukuba kuphononongwe iindlela ezahlukeneyo zokungafezekisi, zinokusebenzisa izixhobo ezinokusetyenziswa ngokupheleleyo kumanzi amdaka amaninzi. Umzekelo: Indlela yokufudula inokuphinda ibuyele kwi-folfids ye-fibrous kumanzi amhlophe, kunye nenqanaba lokubuyisela umva ukuya kuthi ga kwi-95%, kwaye amanzi acacisiweyo angasetyenziswa; Indlela yokuhlanjwa kwamanzi amdaka amanzi amdaka anokubuyisa i-sodium hydroxide, i-sodium sulfide, i-sodium ye-sodium kunye nezinye iityuwa zeSodium zidityaniswe nezinto eziphilayo ngamanzi amnyama. Indlela yokungathathi cala kwamanzi amdaka ilungisa ukubaluleka kwamanzi amdaka; I-Diaction Spientation okanye iFlotation inokususa amasuntswana amakhulu ee-SS kumanzi amdaka; Indlela yokungacacacasi yekhemikhali inokuthoba imbeko; Indlela yonyango lwebhayoloji inokususa i-BOD kunye ne-COD, esebenza ngakumbi kumanzi amdaka eKraft iphepha. Ukongeza, kukwakhona i-osmosis, i-ultrafilitha, i-electrodialysis kunye nezinye iindlela zoncedo lwamanzi amdaka ashiyekileyo ezisetyenziswa ekhaya nakwamanye amazwe.
IXESHA LOKUQALA: UJan-17 ukuya ku-1525
