Mashandisiro Emishonga Yekuchenesa Mvura 1

Isu iye zvino tinobhadhara zvakanyanya kurapa mvura yakasvibiswa kana kusvibiswa kwezvakatipoteredza kunowedzera kuipa.Mishonga yekuchenesa mvura ndeyekubatsira izvo zvakakosha pamidziyo yekuchenesa mvura yetsvina.Makemikoro aya akasiyana mumigumisiro uye kushandisa nzira. Pano tinosuma nzira dzekushandisa pamakemikari akasiyana ekurapa mvura.

I.Polyacrylamide uchishandisa nzira: (Kumaindasitiri, machira, tsvina yemanisipala uye zvichingodaro)

1.dilute chigadzirwa se 0.1% -0,3% mhinduro. Zviri nani kushandisa mvura isina munyu kana uchinyungudusa (semvura yemupombi)

2. Ndokumbira utarise: Paunenge uchidzikisa chigadzirwa, ndokumbira udzore kuyerera kweOtomatiki dosing muchina, kudzivirira kusangana, hove-ziso mamiriro uye kuvhara mumapaipi.

3.Kukurudzira kunofanira kuva pamusoro pemaminitsi makumi matanhatu ne 200-400 rolls / min.Zviri nani kudzora tembiricha yemvura se 20-30 ℃,zvichakurumidzisa kupera.Asi ndapota ita chokwadi kuti tembiricha iri pasi pe60 ℃.

4.Nekuda kwehupamhi ph renji iyo chigadzirwa ichi chinogona kuchinjika, iyo dosage inogona kuva 0.1-10 ppm, inogona kugadziriswa maererano nemhando yemvura.

Mashandisiro ependi mhute coagulant: (Kemikari inonyanya kushandiswa kuchenesa pendi kurapwa)

1. Mukuita kupenda, kazhinji wedzera pendi mhute coagulant A mangwanani, wobva wamwaya pendi zvakajairika. Pakupedzisira, wedzera pendi mhute coagulant B hafu yeawa usati wabva kubasa.

2. Iyo dosing poindi yependi mhute coagulant A mumiririri ari panopinzwa mvura inotenderera, uye dosing point yeajenti B iri panobuda mvura inotenderera.

3. Maererano nehuwandu hwepende yekupfapfaidza uye huwandu hwemvura inotenderera, gadzirisa huwandu hwepende yepende coagulant A uye B panguva.

4. Kuyera kukosha kwePH yemvura inotenderera nguva dzose kaviri pazuva kuti ichengetedze pakati pe7.5-8.5, kuitira kuti mumiririri uyu ave nemigumisiro yakanaka.

5. Kana mvura inotenderera ichishandiswa kwenguva yakati, conductivity, SS kukosha uye yakasimirirwa yakasimba yemvura inotenderera inodarika imwe kukosha, izvo zvichaita kuti mumiririri uyu ave akaoma kunyungudutswa mumvura inotenderera uye saka inokanganisa mhedzisiro. yemumiririri uyu. Inokurudzirwa kuchenesa tangi yemvura uye kutsiva mvura inotenderera isati yashandiswa. Nguva yekuchinja kwemvura inoenderana nerudzi rwependi, huwandu hwepende, mamiriro ekunze uye mamiriro chaiwo emidziyo yekupfekedza, uye inofanirwa kuitwa maererano nekurudziro yehunyanzvi hwepanzvimbo.
