Ka hortagga iyo xakamaynta wasakhowga habka sameynta waraaqaha musqusha waxaa loo qaybin karaa laba qaybood: daaweynta deegaanka ee goobta warshadda iyo daaweynta biyaha wasakhda ah ee ka baxsan goobta.
Daaweynta gudaha geedka
Waxaa ka mid ah: ① xoojinta diyaarinta (booska, dhoobada, diirka, biqilka, iwm.), isticmaalka ururinta boodhka biyaha, yaraynta wasakhowga boodhka ee aqoon-is-weydaarsiga diyaarinta, ururinta qashinka, soo kabashada gubashada tamarta kulaylka, sida isticmaalka jilifka, jajabyada alwaaxa, kuleyliyaha gubista cawska; ② ilaalinta biyaha, dib-u-warshadaynta biyaha cad, dhowr jeer dib-u-warshadaynta biyaha; ③ si loo hagaajiyo soo saarista khamriga madow ee karinta, xoojinta maaraynta qaybta dhaqidda hadda ee miiska si loo kordhiyo tirada qaybaha, loo yareeyo xaddiga khamriga madow ee karinta iyadoo saxarka laga qaadayo dhaqidda, loona isticmaalo soo kabashada dareeraha qashinka karinta ee ugu fiican ee kiimikada iyo tiknoolajiyada tamarta kulaylka, sida soo kabashada alkali, iyo isticmaalka kale ee dareeraha qashinka oo dhammaystiran. Oo isticmaal soo kabashada dareeraha qashinka karinta ee ugu fiican ee kiimikada iyo tiknoolajiyada tamarta kulaylka, sida soo kabashada alkali, iyo sidoo kale isticmaalka kale ee dhammaystiran ee tiknoolajiyada dareeraha qashinka; ④ chlorine dioxide ama oxy-alkali bleaching, ama hydrogen peroxide bleaching, si loo yareeyo lignin chloride, chlorophenol iyo qiiqa kale ee sunta ah ee biyaha wasakhda ah; ⑤ wasakhda wasakhda ah ee lagu nadiifiyo habka soo saarista uumiga si dib loogu isticmaalo si loo yareeyo qiiqa biyaha wasakhda ah ee sulfur-ka yaraaday iyo walxaha milma ee organic-ga; ⑥ ururinta khamriga madow ee daadanaya iyo kuwa daadanaya, dareeraha cagaaran, dareeraha cad, oo leh kontoroolka kumbuyuutarka elektaroonigga ah si loo cabbiro fiirsashada, si toos ah loogu celiyo garaaca haanta ee u dhiganta, si loo yareeyo qiiqa; ⑦ soo kabashada fiilooyinka lumay, yaraynta waxa ku jira adkaha la hakiyey ee ku jira biyaha wasakhda ah; ⑧ si loo hagaajiyo soo kabashada saabuunta turpentine sulphate, yaraynta qiiqa walxaha sunta ah; ⑨ daaweynta qashinka adag, isticmaalka gubashada si loo soo celiyo kulaylka, isticmaalka dhammaystiran iyo buuxinta godka saddexda nooc ee daaweynta; ⑩ daaweynta boodhka, waxaa loo isticmaali karaa ka saarista boodhka korontada, ka saarista boodhka filimka biyaha iyo kala soocida duufaanta iyo qalabka kale; farsamaynta wasakhowga hawada Kala soocida iyo qalabka kale; daaweynta wasakhowga hawada, ururinta gaaska urta ee aqoon-is-weydaarsi kasta, oo ay ku jiraan gaaska urta leh ee uumiga biyaha wasakhda ah, ka dib qaboojinta, fuuqbaxa, u adkaysta qaraxa iyo tallaabooyin kale, oo loo diro kuleyliyaha, foornada soo kabashada alkali ama daaweynta gubashada foornada lime;? Daawaynta buuqa, qaado tallaabooyin lagu baabi'inayo gariirka, dahaarka dhawaaqa oo u beddel qalabka buuqa yar.
Daaweynta biyaha wasakhda ah ee ka baxsan warshadda
Biyaha wasakhda ah ee ka soo baxa guud ahaan meesha laga soo saaro geedka oo dhan waxaa lagu daaweeyaa heerka koowaad ama labaad ka hor inta aan lagu shubin biyo, ama biyaha wasakhda ah waxaa loo isticmaalaa waraabka, ciidda iyo dhirtana waxaa loo isticmaalaa in lagu nadiifiyo biyaha wasakhda ah. Daaweynta aasaasiga ah waxay inta badan ka saartaa walxaha la hakiyey, iyadoo la adeegsanayo habab sida fadhiisinta iyo shaandhaynta iyo sabbeynta hawada. Dhirta shaqsiga ah waxay ku dartaa flocculants biyaha wasakhda ah si looga saaro qaar ka mid ah walxaha kolloidal ee milmay, sida lignin iyo midabyada. Daaweynta aasaasiga ah ee guud waxay ka saari kartaa 80 ~ 90% SS iyo 20% BOD5. daaweynta labaad ee daaweynta kiimikada, inta badan si looga saaro BOD5. Shiinaha waxaa jira dhowr dhir ah oo lagu dabaqay habkan, iyadoo la tirinayo balliyada oksaydhka, shaandheeyayaasha biofilters, bio-turntable iyo dhoobada firfircoon (oo ay ku jiraan nuugista iyo dib u soo noolaynta, hawo-mareenka degdega ah, oksaydhka xiriirka). Daaweynta labaad ee guud waxay ka saari kartaa 60 ~ 95% BOD5. wadamada horumaray ee warshadaha, waxaa jira dhir shaqsiyeed oo loogu talagalay daaweynta kala-goynta midabka saddexaad iyo nadiifinta biyaha wasakhda ah, si loo gaaro heerka biyaha la cabbo, laakiin kharashku waa qaali.
Warqadda musqusha ee Yashi 100% ma isticmaasho bacrimin kiimiko ah iyo sunta cayayaanka. Geedi socodka oo dhan wuxuu qaataa tignoolajiyada xoqidda jirka iyo kuwa aan cadaynayn si loo hubiyo inaysan jirin haraaga sunta ah iyo kuwa waxyeelada leh sida kiimikooyinka, sunta cayayaanka, biraha culus, iwm. Waxaa tijaabisay hay'adda baaritaanka ee caalamiga ah ee SGS mana ku jirto walxo sun ah iyo kuwa waxyeello leh iyo kansar. Isticmaalku waa mid ammaan ah macaamiishuna way hubsan yihiin.
