Nthowa yakuchizgirako maji ghakufipirwa ya DPG. Chakwamba, maji ghakufipirwa ghakulongozgeka na asidi - base flocculation, ndipo maji ghakufipirwa ghakusefeka ghakunjira mu selo ya electrolytic iyo yili na micro-} electrolytic filler pa 60-80℃C, micro- pafupifupi magesi kwa maora ghaŵiri mpaka 5, pamanyuma pa micro-electrolysis Maji ghakufipirwa ghakusefeka, ndipo maji ghakufipirwa ghakusefeka ghakusazgikira na 10% kufika pa 30 ml ya hydrogen peroxide / maji ghakufipirwa ku msinkhu wa 30% hydrogen peroxide, wakusinthika ku pH=2 ku 4, kuchizgika kwa maora ghaŵiri mpaka 5, ndipo pamanyuma pake wakusazgikira ku flocculation pa chiŵelengero cha 200 mpaka 500 mg / L cha maji ghakufipirwa. Munthu uyo ​​wakugwira ntchito ku PAC wakupangika, pH wakusinthika ku 8 kufika pa 10, ndipo nyengo ya kusefukira kwa maji ni maora 1 panji 2. Pamanyuma pa kusefukira kwa maji, vikusefa dankha, ndipo maji ghakufipirwa ghakusefeka ghakusinthika na carbon na resini yakugwira ntchito, ndipo chiŵelengero cha CODcr chikufumiskika pa 98%, kufika pa msinkhu wa kufumiska. Nthowa iyi yili na ndondomeko yipusu, kuŵika ndalama zichoko, kugwiriskira ncito nkhongono zicoko, kufunyapo kwa COD kwakukwana, kungafika pa 98%, nkhongono yiwemi ya wovwiri, kukumana na vigaŵa vyakufumiramo, ndipo nchakusuzga yayi kupanga mafakitale.

DPG yakukhozgera ndiyo yikupangiska kuti munthu waŵe na luwiro lwa labala, wakuchimbira mwaluŵiro wa labala wakupangika na labala na labala wakupangika na ŵanthu, ndiposo wakuchitiska kuti thupi liŵe na thiazoles, thirams na sulfanemide accelerators. Chinthu icho chikusangika chili na kukana kuwemi. Iwo ŵakugwiriskira ncito comene kupanga vinthu vya raba nga ni matayala, mapepala gha labala na vingwe. Pa nyengo yakupanga DPG ya accererator, mchere ukuru chomene wakukwera - pafupifupi ukupangika maji ghakufipirwa ghakupangika na vyakumera, ivyo ni vyakusuzga kuvigwiliskira ntchito, ndipo kupanga kwake na kupanga kwake kukukanizgika chomene chifukwa cha kufinyikizgika kwa chilengiwa. Maji ghakufipirwa mu ndondomeko ya kupanga DGP chomenechomene ghakufuma ku ndondomeko ya mafuta gha moŵa na kuchapa maji. Mchere na COD vikukwera, vikuŵa na mtundu na sungu, ndipo maji ghali na vinthu vyakupambanapambana vyakupangika na heterocyclic, ivyo vikusuzga kuvipwelelera na nthowa za biochemical. Pasono, pali malipoti ghachoko waka ghakukhwaskana na umo maji ghakufipirwa ghakuchitira, chomenechomene evaporative distillation na ndondomeko zinyake, izo zili na nkhongono zinandi ndiposo nkhongono ziheni chomene.

Nthowa ya raba vulcanization DPG ya maji ghakufipirwa: cakwamba, maji ghakufipirwa ghakuŵikika mu asidi -base flocculation, ndipo maji ghakufipirwa ghakusefeka ghakunjira mu selo ya electrolytic iyo yili na micro-} electrolytic filler ya electrolysis na kusefa, ndipo maji ghakufipirwa ghakusefeka ghakusazgikiraso na hydrogen peroxide ya Fenton, pamanyuma pa oxidation. Maji ghakufipirwa ghakupangika na flocculation, ghakuŵikika mu maji ndipo ghakusefeka. Maji ghakufipirwa ghakusefeka ghakusinthika na carbon na resini yakugwira ntchito, ndipo chiŵelengero cha CODcr chikufika pa 98%, kufika pa msinkhu wa kufumiska.

Nthowa ya raba vulcanization DPG ya maji ghakufipirwa, maji ghakufipirwa ghakuŵikika pa asidi - base flocculation, ndipo maji ghakufipirwa ghakusefeka ghakunjira mu selo ya electrolytic iyo yili na micro-} electrolytic filler pa 60 {{3}80℃C, micro{}}}}}}" magesi gha maora ghaŵiri mpaka 5, ndipo maji ghakufipirwa panyuma pa micro-electrolysis para vyachitika. Kusefa, kusazgapo 10 mpaka 30 ml ya hydrogen peroxide pa lita ya maji ghakufipirwa ghakusefeka, kusazgapo hydrogen peroxide na 30% hydrogen peroxide, kusintha pH =2 ku 4, kuchizga kwa maora ghaŵiri mpaka 5, ndipo pamanyuma pake kusazgirapo PAC ya flocculant pa chiŵelengero cha 200 kufika ku 500 mg / L ya maji ghakufipirwa. Kusintha kwa nyengo, kusintha kwa pH 8 ~ 10, nyengo yakukhazikika ni maora 1-2; kusefa pamanyuma pa kuseŵera, maji ghakufipirwa ghakusefeka ghakusinthika na carbon na resini yakugwira ntchito, ndipo chiŵelengero cha CODcr chikufumiskika pa 98%.
