Polyacrylamide- Basa reMasewage Flocculants

Kuti tsvina ibude kana kuti ishandiswezve mushure meKurapwa, makemikari akasiyana-siyana anofanira kushandiswa muKurapwa kweMarara. Nhasi,Vatengesi vePAM (Polyacrylamide)ndichakuudza nezve flocculants:

Flocculant: Dzimwe nguva inonziwo coagulant, inogona kushandiswa senzira yekusimbisa kupatsanurwa kwemvura yakasimba, uye inogona kushandiswa mutangi rekutanga rekugadzika, tangi rechipiri rekugadzika, tangi reflotation, kurapa kwechitatu kana kurapwa kwepamusoro uye zvimwe zvinongedzo zvemaitiro.

Maflocculant anoshandiswa senzira yekusimbisa kupatsanurwa kwemvura yakasimba mumunda wekuchenesa tsvina. Anogona kushandiswa kusimbisa kuchekwa kwemvura kubva mutsvina, kugadziriswa kwemvura inoyerera uye kuchekwa kwemvura mushure mekugadziriswa kwetsvina, uye anogonawo kushandiswa pakurapa tsvina yepamusoro kana kurapwa kwetsvina yepamusoro. Kana akashandiswa pakugadzirisa tsvina isati yapera, maflocculant nemacoagulant anova masludge conditioners kana dehydrating agents.

Pakushandisa maflocculant echinyakare, nzira yekuwedzera macoagulant aids inogona kushandiswa kuwedzera simba re flocculation. Semuenzaniso, kushandisa activated silicic acid se coagulant aid ye inorganic flocculants dzakadai se ferrous sulfate ne aluminium sulfate uye kuwedzera izvi mu sequence kunogona kuita kuti flocculation ibudirire. Saka, maererano ne layman, inorganic polymer flocculant IPF inogadzirwa nekubatanidza coagulant aid ne flocculant uye yozowedzerwa pamwe chete kuti zvive nyore kushanda kwemushandisi.

Kurapa kwekuonda kunowanzoiswa pamberi penzvimbo yekuparadzanisa mvura yakasimba, uye pamwe chete nenzvimbo yekuparadzanisa, inogona kubvisa zvinhu zvakamiswa uye zvinhu zvecolloidal zvine saizi ye1nm kusvika 100μm mumvura isina kubikwa, kuderedza kusvibiswa kwemvura uye CODCr, uye inogona kushandiswa mukurapa nzira dzekuchenesa tsvina. Kurapa, kurapwa kwepamusoro, kunogonawo kushandiswa pakurapa tsvina yakasara. Kurapa kwekuonda kunogonawo kubvisa tupukanana nemabhakitiriya anokonzera hutachiona mumvura, uye kubvisa mafuta emulsified, chroma, heavy metal ions nezvimwe zvinosvibisa mumvura yetsvina. Kubviswa kwephosphorus iri mutsvina kunogona kusvika 90% kana coagulation sedimentation ichishandiswa kurapa phosphorus. ~95%, ndiyo nzira yakachipa uye inoshanda zvakanyanya yekubvisa phosphorus.

Mukugadzirisa tsvina yetsvina, zvimwe zvinhu zvinoshandiswa zvichashandiswa. Nhasi,Mugadziri wePAMvakaunza chimwe chete chazvo. Uchiri kunzwisisa here? Teerera Yuncang uye pindura rumwe ruzivo rwekuchenesa tsvina!
