Sewage kurapa makemikari

Kurapa kwemvura inzira yakaoma iyo inoda kushandiswa kwemhando dzakasiyana dzemakemikari kuti ubatsire kunatsa mvura. Floculants ndeimwe yemakemikari akakosha ayo anotamba chinzvimbo chakakosha mune Sewage kurapwa maitiro. Chinyorwa ichi chinosuma zvakadzama madhiri emakemikari ekurapa ekurapa, maindasitiri ekunyorera eanobhururuka mukurapa kwekurapa, basa remakemikari emakemikari, uye matanho ekutarisira anoshandisa anofamba.

Iyo Dosage yemakemikari ekurapa anoenderana nemhando yegungwa, maitiro ekurapa uye mamiriro chaiwo. Izvi zvinotevera mienzaniso yemadhimoni emamwe mawonero emakesagedhi ekurapa ekurapa:

Polandauminum chloride (pac):Inowanzoshandiswa sechileculant, inogona kuita zvisina kukodzera kubhadharwa coldidal coldles yekugadzira kugadziriswa kwehydroxide micelles kubvisa yakasimudzwa solids uye inorema sesimbi ion. Mumamiriro ezvinhu akajairwa, dosage pane toni yemvura yakaomeswa ndeyekuti makumi emakore emakumi emakumi matatu.

Polwandacrrylambide (Pam):Inoshandiswa seyakawirirana kuti uvandudze kusimba uye kugadzikana kweiyo floc. Kazhinji inoshandiswa pamwe chete nePolalluminium chloride

Floculants inonyatso kushandiswa mukurapa kwemarara, kunyanya kusanganisira zvikamu zvinotevera:

Maindasitiri marara ekurapa Iko kushandiswa kweanobhururuka kunogona kubvisa izvi zvinoputika uye kunatsa iyo marara.

Sangano reMadyasi Yokurapa Iko kushandiswa kweanobhururuka kunogona kubvisa zvinobudirira izvi zvisina kufanira uye kuvandudza mhando yemvura.

Kurapa kwemauto ekurapa Iko kushandiswa kweanobhururuka kunogona kubvisa zvinobudirira izvi zvisina kufanira uye kuvandudza mhando yemvura.

Maindasitiri marara: Iko kushandiswa kweanobhururuka kunogona kubvisa zvinokwanisika kudzikisira solids, simbi inorema simbi uye organic pollutants mumvura uye kuvandudza mhando yemvura.

Izvo zvinoshandiswa zvecherechedzo makemikari zvinonyanya kusanganisira zvikamu zvinotevera:

Kubviswa kweSolided Solids: Kuburikidza nekuita kweanobhururuka, solids solids mumarara akaunganidzwa mumatanho ekuti afambise zvakarembera.

Kubviswa kwesimbi inorema simbi

Kubviswa kweiyo organic Pellutants: Kuburikidza nekuita kweanobhururuka, organic Pollutants mumarara anoshandurwa kuita hydroxide precipitates kana oxidized mune zvimwe zvinhu zvekubvisa nyore.

PH Kugadziriswa: Gadzirisa iyo pH yemarara kuburikidza neyekuita alkali kana acid yekuchenesa marara.

Zvinhu zvekucherekedza kana uchishandisa flyculants:

Sarudza iyo yakakodzera flocculant: dzakasiyana famba dzine mabasa akasiyana uye mhedzisiro. Izvo zvinodikanwa kusarudza iyo yakakodzera floculant zvinoenderana nemamiriro ezvinhu chaiwo.

Dzora dosage yemushonga: isina kukwana dosage ichakanganisa mhedzisiro, uye dosage yakawandisa ichaita kuti marara uye kurasikirwa kwehupfumi. Naizvozvo, zvinodikanwa kudzora iyo yakakodzera dosage maererano nemamiriro chaiwo.

Simbisa zvakakwana: Simudza iyo floculant uye mvura zvakakwana kuti isanyatso nyura uye kuita.

Teerera tembiricha nePP kukosha: tembiricha uye ph kukosha zvine chekuita nemhedzisiro yekubvisa uye inoda kudzorwa nokungwarira.
