Polyacrylamide- Basa reSewage Flocculants

Kuti ubvise kana kushandisa zvakare Sewage mushure mekurapwa, akasiyana Makemikari anofanirwa kushandiswa muSewage Treatment process.Nhasi,PAM (Polyacrylamide) vatengesiachakuudza nezve flocculants:

Flocculant: Dzimwe nguva zvakare inonzi coagulant, inogona kushandiswa senzira yekusimbisa yakasimba-yemvura kupatsanurwa, uye inogona kushandiswa mukutanga kugadzirisa tangi, yechipiri kugadzirisa tangi, flotation tangi, kurapwa kwepamusoro kana kurapwa kwepamusoro uye mamwe maitiro ekubatanidza.

Flocculants inoshandiswa senzira yekusimbisa kupatsanurwa kwakasimba-mvura mumunda wekuchenesa tsvina.Iwo anogona kushandiswa kusimbisa iyo yekutanga sedimentation yetsvina, flotation kurapwa uye yechipiri sedimentation mushure meyakagadziriswa sludge process, uye inogona zvakare kushandiswa pakurapa kwepamusoro kana kurapwa kwepamusoro kwetsvina.Kana ichishandiswa kugadzirisa kusati kwapera mvura yetsvina yakawandisa, maflocculants uye coagulants anova madhaka conditioners kana dehydrating agents.

Paunenge uchishandisa zvechinyakare flocculants, nzira yekuwedzera coagulant aids inogona kushandiswa kuwedzera iyo flocculation effect.Semuyenzaniso, kushandisa activated silicic acid seyamuro ye coagulant ye inorganic flocculants senge ferrous sulfate uye aluminum sulfate uye kuvawedzera munhevedzano vanogona kuwana yakanaka flocculation.Naizvozvo, mukutaura kwevasina basa, iyo inorganic polymer flocculant IPF inonyatso gadzirirwa nekubatanidza iyo coagulant rubatsiro uye iyo flocculant uye yobva yawedzerwa pamwechete kuti kurerutsa kushanda kwemushandisi.

Coagulation kurapwa inowanzoiswa pamberi peiyo yakasimba-yemvura yekuparadzanisa nzvimbo, uye yakasanganiswa nenzvimbo yekuparadzanisa, inogona kunyatsobvisa yakamiswa yakasimba uye colloidal zvinhu zvine particle size ye1nm kusvika 100μm mumvura mbishi, kuderedza effluent turbidity uye CODCr, uye inogona kushandiswa mukugadziriswa kwemaitiro ekugadzirisa tsvina.Kurapa, kurapwa kwepamusoro, kunogona zvakare kushandiswa kune yakasara sludge kurapwa.Coagulation kurapwa kunogonawo kubvisa zvinobudirira tupukanana uye pathogenic mabhakitiriya mumvura, uye kubvisa emulsified oiri, chroma, heavy metal ions uye zvimwe zvinosvibisa mutsvina.Kubvisa phosphorus iri mutsvina inogona kusvika pa90% kana coagulation sedimentation ichishandiswa kurapa phosphorus.~ 95%, ndiyo yakachipa uye inoshanda zvakanyanya nzira yekubvisa phosphorus.

Mukugadzirisa kwekuchenesa tsvina, mamwe maajenti achashandiswa.Nhasi, thePAM Mugadziriakasuma imwe chete yadzo.Uchiri kunzwisisa here?Teerera kuYuncang uye upindure ruzivo rwakawanda rwekuchenesa tsvina kwauri!
