Ebe ihe omume a dị ebe a, bịa chọta anyị!
Ihe ngosi anyị gụnyere ngwaahịa ndị a:
Ọkwa dị elu nke na-eme ka agba ya dị ọcha
Usoro CW nke na-arụ ọrụ nke ọma nke na-emepụta flocculant bụ cationic organic polymer nke ụlọ ọrụ anyị mepụtara n'onwe ya nke na-ejikọta ọrụ dị iche iche dịka decolorization, flocculation, mbelata COD na mbelata BOD. A na-akpọkarị ya dicyandiamide formaldehyde polycondensate. A na-ejikarị ya eme ihe maka ọgwụgwọ mmiri mkpofu ụlọ ọrụ dịka ákwà, ibipụta na ịcha agba, ime akwụkwọ, agba, igwu ala, ink, igbu anụ, mkpofu ihe mkpofu, wdg.
Polyacrylamide
Otu amide nke polyacrylamide nwere ike ịdị n'otu na ọtụtụ ihe, na-enweta mmetụta na-adịghị mma.
Njikọ hydrogen, polyacrylamide dị oke arọ na ion a na-etinye n'ime ya
A na-etolite àkwà mmiri n'etiti ihe ndị ahụ, a na-emepụta flocculation, a na-emekwa ka sedimentation nke ihe ndị ahụ dịkwuo ngwa ngwa, si otú a na-eme ka ha dị ngwa ngwa.
mezuo ebumnuche kachasị elu nke nkewa siri ike na mmiri mmiri.
A na-ejikarị ya eme ihe maka iwepụ mmiri nsị, nkewa mmiri siri ike na mmiri na ịsa kol, ime ka mmiri nsị dị ọcha na ime akwụkwọ. Enwere ike iji ya mee ihe maka mmiri nsị ụlọ ọrụ mmepụta ihe na ọgwụgwọ nsị mmiri n'ime obodo. Enwere ike iji ya mee ihe n'ụlọ ọrụ akwụkwọ: melite ike akọrọ na mmiri mmiri nke akwụkwọ, melite ọnụego njigide nke eriri na ihe ndị na-ejupụta ya. Enwere ike iji ya dị ka ihe mgbakwunye maka ihe apịtị maka ubi mmanụ na igwu ala.
polyaluminum chloride
Polyaluminum chloride bụ ụdị ọhụrụ nke inorganic polymer coagulant dị elu nke na-arụ ọrụ nke ọma. N'ihi mmetụta nke ion hydroxide na polymerization nke polyvalent anions, a na-emepụta ihe na-emepụta mmiri polymer inorganic nke nwere nnukwu ibu molekul na nnukwu chajị eletrik.
A na-ejikarị ya eme ihe n'ịsacha mmiri, ọgwụgwọ mmiri mkpofu, ịkpụ ihe n'ụzọ ziri ezi, ime akwụkwọ, ụlọ ọrụ ụlọ ọgwụ na kemịkalụ kwa ụbọchị. Ọnụ ego mmepụta mmiri dị ala site na 20% ruo 80% karịa flocculants ndị ọzọ na-adịghị ahụkebe. Ọ nwere ike ịmepụta floc ngwa ngwa, okooko osisi alum buru ibu ma ọsọ sedimentation dị ngwa ngwa. Uru pH kwesịrị ekwesị dị obosara (n'etiti 5-9), uru pH na alkalinity nke mmiri a gwọrọ na-ebelata obere. Flocculant pụrụ iche maka ọgwụgwọ mmiri ọdụ.
Usoro ngwaahịa ụlọ ọrụ anyị mepụtara nwere ịdị arọ molekul dị iche iche, nke nwere ike igbo mkpa nke ngwa dị iche iche. Flocculant pụrụ iche maka ọgwụgwọ mmiri ọdụdụ nwere oke ibu molekul dị iche iche, ọ dị mfe ịgbaze, dị mfe itinye, ma na-arụ ọrụ nke ọma na oke pH dị iche iche.
Decolorization flocculant maka mmiri mkpofu coking
Ugbu a, usoro ọgwụgwọ mmiri mkpofu coking a na-ejikarị eme ihe na-anabata ọgwụgwọ biochemical, mana n'ihi ọnụnọ nke ọtụtụ ihe ndị na-adịghị agbanwe agbanwe, COD, chromaticity, phenols na-agbanwe agbanwe, polycyclic aromatic hydrocarbons, cyanide, petroleum, total cyanide, total nitrogen, ammonia nitrogen, wdg. Ọtụtụ mgbe, ha enweghị ike iru ụkpụrụ mwepụ mba, yabụ na ọgwụgwọ dị elu mgbe usoro biochemical gasịrị, anyị kwesịrị ilekwasị anya na iwepụ otu ndị na-adịghị agbanwe agbanwe, a naghịkwa enweta mmetụta mwepụ site na flocculants nkịtị. Decolorization flocculant nke a na-eji maka mmiri mkpofu coking nwere ike nweta nsonaazụ kacha mma mgbe ejiri ya na carbon arụ ọrụ.
