Sewage treatment makemikari

Kugadziriswa kwemvura yakasviba inzira yakaoma inoda kushandiswa kwemakemikari akasiyana-siyana kubatsira kuchenesa mvura.Flocculants ndeimwe yemakemikari anokosha anoita basa rinokosha mukugadzirisa tsvina.Ichi chinyorwa chinozivisa zvakadzama nezve dosage yekuchenesa tsvina makemikari, maindasitiri ekushandisa e flocculants mukugadziriswa kwetsvina, basa remakemikari etsvina, uye matanho ekushandisa maflocculants.

Kuyerwa kwemakemikari ekuchenesa tsvina kunoenderana nemhando yetsvina, nzira yekurapa uye mamiriro chaiwo.Iyi inotevera mienzaniso yemadosi emamwe makemikari akajairika ekuchenesa tsvina:

Polyaluminium chloride (PAC):Inowanzo shandiswa se flocculant, inogona kuita neine negative charged colloidal particles kuti ibudise kugadzirisa hydroxide micelles kubvisa yakaturikwa yakasimba uye heavy metal ions.Mumamiriro ezvinhu akajairwa, muyero patani yemvura yakasvibirira inenge makumi emagiramu, asi iyo dosi chaiyo inoda kugadziridzwa zvinoenderana nemhando yemvura yakasvibira uye maitiro ekuita.

Polyacrylamide (PAM):inoshandiswa se coagulant kuvandudza kusimba uye kugadzikana kweiyo floc.Inowanzo shandiswa pamwe chete nepolyaluminium chloride, muyero patani yemvura yakasvibira inenge magiramu mashoma, asi iwo chaiwo dosi inoda kugadziridzwa zvinoenderana nemamiriro ekuita uye marudzi ezvinosvibisa.

Flocculants anoshandiswa zvakanyanya mukurapa mvura yetsvina, kunyanya kusanganisira anotevera mapoka:

Kugadziriswa kwemvura yetsvina yeindasitiri: Mvura yetsvina yeindasitiri ine huwandu hukuru hwezvakamiswa zvakaomeswa, heavy metal ions uye organic pollutants.Iko kushandiswa kwemaflocculants kunogona kunyatsobvisa izvi zvinosvibisa uye kuchenesa mvura yakasviba.

Kugadziriswa kwesuweji yemumba: Tsvina yemumba ine huwandu hukuru hwezvinhu zvakasimirirwa uye zvakamiswa zvakasimba.Kushandiswa kwemaflocculants kunogona kunyatsobvisa izvi zvinosvibisa uye kunatsiridza kunaka kwemvura.

Kurapwa kwemvura yetsvina yepurazi: Mvura yepasi yetsvina ine huwandu hukuru hwezvinhu zvakaomeswa, ammonia nitrogen nezvimwe zvinokuvadza.Kushandiswa kwemaflocculants kunogona kunyatsobvisa izvi zvinosvibisa uye kunatsiridza kunaka kwemvura.

Mvura yetsvina yemaindasitiri: Kushandiswa kwemaflocculants kunogona kunyatso bvisa zvakamiswa zvimisikidzwa, heavy metal ions uye organic pollutants mumvura nekuvandudza kunaka kwemvura.

Mabasa emakemikari etsvina anonyanya kusanganisira zvinotevera zvikamu:

Kubviswa kwezvakarembera zvakamira: Kuburikidza nekuita kwema flocculants, zvakaturikwa zvakamira mumvura yetsvina zvinounganidzwa kuita clumps kufambisa sedimentation uye kusefa.

Kubviswa kweheavy metal ions: Kuburikidza nekuita kwema flocculants, heavy metal ions mumvura ine tsvina inoshandurwa kuita hydroxide precipitates kuti ibvise nyore.

Kubviswa kwezvinosvibisa organic: Kuburikidza nekuita kwezvinoyerera, organic zvinosvibisa mumvura yetsvina zvinoshandurwa kuita hydroxide precipitates kana oxidized kuita zvimwe zvinhu kuti zvive nyore kubviswa.

pH kugadzirisa: Gadzirisa pH yemvura yakasviba kuburikidza nekuita kwealkali kana asidhi kuchenesa mvura yakasviba.

Zvinhu zvekuona kana uchishandisa flocculants:

Sarudza iyo yakakodzera flocculant: akasiyana flocculants ane akasiyana mabasa nemhedzisiro.Zvakakosha kusarudza flocculant yakakodzera maererano nemamiriro chaiwo.

Dzora chipimo chemushonga: Kusakwana dosage kuchakanganisa mhedzisiro, uye yakawandisa dosi inokonzeresa kurasika uye kurasikirwa kwehupfumi.Naizvozvo, zvinodikanwa kudzora kuyerwa kwakakodzera maererano nemamiriro chaiwo.

Sungai zvakakwana: Gadzirai flocculant uye mvura zvakakwana kuti inyunguduke uye itai.

Teerera kune tembiricha uye pH kukosha: Tembiricha uye pH kukosha zvine mhedzisiro pamhedzisiro yeflocculant uye inoda kudzorwa nekungwarira.
