Kana uchifunga zvakoKurapwa kwemvuraKuita, tanga nekutarisa zvaunofanira kubvisa kubva mumvura kuitira kuti usangane zvinodiwa. Nemakemikari akakodzera kurapwa, iwe unogona kubvisa ion uye zvidiki zvakanyungudutswa zvinopera kubva pamvura, pamwe nekumiswa solids. Makemikari anoshandiswa mune sewage kurapa zvirimwa zvinonyanya kusanganisira:Floculant, PH Realator, Coagulant.
Floculant
Inobhururuka inoshandiswa mune yakasarudzika yeindasitiri uye mashandisiroKubatsira kubvisa kumiswa kwakamiswa kunobva kumarara nekukasira nekuisa masheya mumashiti kana "Flocs" ayo anofamba pamusoro kana akagara pasi. Vanogona zvakare kushandiswa kupfava lime, kutarisisa sludge uye kusvibiswa solids. Natural kana mineral flyculants inosanganisira anoshanda silika uye polysaccharides, nepo inogadzira ficha inowanzoitika polycrylamide.
Zvichienderana nemhosva uye makemikari okuumbwa kweiyo iyo marara, inobhururuka inogona kushandiswa yega kana musanganiswa necalagulants. Vanobhururuka vanosiyana nemabhuku ekuti ivo vanowanzo polymers, nepo kanokona kazhinji vanowanzo. Saizi yavo yemulecular (uremu) uye kubhadharisa density (iyo muzana yemamolecules ine anonic kana cation capges) inogona kusanganisa "kuraira kwezvidimbu mumvura uye kuishungurudza pamwe chete uye kunonoka. Muzhinji, anionic anofamba-famba anoshandiswa kuteya madiki madiki, nepo cationlic floculants anoshandiswa kubaya organic zvigadziko zvemberi.
PH Regulator
Kubvisa simbi uye kumwe kusvibiswa kwakasvibiswa kubva kumarara, ph regulator inogona kushandiswa. Nekurera iyo pH yemvura, uye nekuwedzera kuwanda kweiyo yakaipa hydroxide ion, ichi chinokonzeresa kupomerwa masimbi ioni. Izvi zvinoguma nekupiswa kunze kweiyo dense uye insoluble yesimbi zvimedu.
Coagulant
Kune chero kurwadza kwekurapa kwekurapa uko kunobata kwakamiswa solids, kanobati kunogona kusanganisa zvinomiswa zvisina kunaka kubvisa nyore kubvisa nyore. Kemical Coagulants inoshandiswa pakureverera kwemasango emvura marara akapatsanurwa mune imwe yemapoka maviri: organic uye inorganic.
Mbiriyoni inorembachelants ndeye mutengo-inoshanda uye inogona kushandiswa kune yakakura mhando dzekushandisa. Ivo vanonyanya kushanda pamusoro pemvura yakasviba yeripi rakaderera turbidity, uye iyi application haina kukodzera kuti organic kabhandei. Kana zvakawedzerwa kumvura, inorganic kanokona kubva kuAluminium kana simbi inodaidzira, inomutsa kusvibiswa mumvura uye kuchenesa. Izvi zvinozivikanwa se "kutsvaira-uye-kuonda" michina. Kunyange zvichishanda, maitiro acho anowedzera huwandu hwakazara hwekutsvedza izvo zvinoda kubviswa mumvura. Mukwati embiru yeIsorganic anosanganisira aluminium sulfate, aluminium chloride, uye ferric sulfate.
MaComtic Coagulants ane zvakanakira dosi yakaderera, zvishoma sludge kugadzirwa uye hapana mhedzisiro pane iyo pH yemvura yakabatwa. Mienzaniso yeCommal Orgulants inosanganisira polyamines uye polydimethl cilallyl amonium chloride, pamwe nemirela, formine, forminehdehyde nemannini.
