Ndeapi Makemikari Anowanzo Kushandiswa MuSewage Treatment Plants?

Paunenge Uchifunga ZvakoWastewater TreatmentMaitiro, Tanga Nekuona Zvaunoda Kubvisa Kubva Mumvura Kuti Uzadzise Zvinodiwa Zvekuburitsa. NeKurapa Kwakakodzera Kwemakemikari, Unogona Kubvisa Ions uye Zvidiki Zvinyungudutswa Kubva Mumvura, Pamwe Nezvakarembesa Solids. Makemikari Anoshandiswa MuSewage Treatment Plants Anonyanya Kusanganisira:Flocculant, Ph Regulator, Coagulant.

Flocculant
Flocculants Inoshandiswa Mukati Rakawanda Wemaindasitiri uye ZvishandisoKubatsira Kubvisa Masimbi Akamiswa Kubva Mumvura Yakasviba Nekuisa Zvinosvibisa MuMashiti kana "Mafura" Anoyangarara Pamusoro Kana Kugara Pazasi. Ivo Vanogona zvakare Kushandiswa Kupfavisa Lime, Concentrate Sludge uye Dehydrate Solids. Zvisikwa kana zvicherwa Flocculants zvinosanganisira Active silica uye Polysaccharides, nepo Synthetic Flocculants Kazhinji Polyacrylamide.
Zvichienderana nekuchaja uye Kemikari Kuumbwa kwemvura yakasviba, Flocculants Inogona Kushandiswa Ega kana Kusanganiswa neCoagulants. Flocculants Inosiyana neCoagulants Mukuti Iwo Anowanzo MaPolymers, nepo Coagulants Anowanzo Munyu. Yavo Molecular size (uremu) uye Charge Density (iyo muzana yeMamorekuru ane Anionic kana Cationic Charge) Inogona Kusiyanisa "Kuenzanisa" Kuchaja Kwezvikamu Zviri MuMvura uye Kuita Kuti Abatane Pamwe Uye Dehydrate. Kazhinji, Anionic Flocculants Anoshandiswa Kuteya Mamineral Particles, nepo Cationic Flocculants Inoshandiswa Kuteya Organic Particles.

PH Regulator
Kubvisa simbi uye zvimwe zvakanyungudutswa zvakasvibiswa kubva mumvura yakasviba, pH regulator inogona kushandiswa. Nekusimudza pH yemvura, uye nekudaro kuwedzera huwandu hweiyo negative hydroxide ions, izvi zvinokonzeresa kuti maion esimbi anochajiswa zvakanaka kuti abatane neaya anochajiswa zvakashata maion hydroxide. Izvi zvinoguma nekusefa kwesimbi dzakakora uye dzisinganyunguriki.

Coagulant
Kune Chero Chero Mvura Yakasviba Kurapa Maitiro Inobata Masori Akamiswa, Coagulants Inogona Kubatanidza Yakamiswa Inosvibisa Kuti Ibvise Nyore. Kemikari Coagulants Inoshandiswa Kugadzirira Kugadziriswa Kwemvura Yetsvina Yeindasitiri inokamurwa kuita chimwe chezvikamu zviviri: Organic uye Inorganic.
Inorganic Coagulants Inodhura-Inoshanda uye Inogona Kushandiswa Kune Yakafara Range Yekushandisa. Iwo Anonyanya Kushanda Pamvura Yakasvibira Yechero Yakaderera Turbidity, Uye Ichi Chikumbiro Hachina Kufanira Kune Organic Coagulants. Kana Yawedzerwa kuMvura, Inorganic Coagulants Kubva Aluminium kana Iron Precipitate, Inobvisa Kusvibiswa Mumvura uye Kuichenesa. Izvi Zvinozivikanwa se "Sweep-And-Flocculate" Mechanism. Ichiri Kushanda, Maitiro Anowedzera Huwandu Hwese hweSludge Inoda Kubviswa Kubva Mumvura. Yakajairika Inorganic Coagulants inosanganisira Aluminium Sulfate, Aluminium Chloride, uye Ferric Sulfate.
Organic Coagulants Ine Zvakanakira Yakaderera Dosage, Kadiki Sludge Kugadzira uye Hapana Mhedzisiro PaPh Yemvura Yakabikwa. Mienzaniso Yezvakajairwa Organic Coagulants inosanganisira Polyamines uye Polydimethyl Diallyl Ammonium Chloride, Uye Melamine, Formaldehyde uye Tannins.
