Iko kusanganiswa kwePAM nePAC kwakanyanya kushanda?

Mukugadzirisa tsvina, kushandisa mvura yekuchenesa mumiririri wega kazhinji inokundikana kuita mhedzisiro. Polyacrylamide (PAM) uye polyaluminium chloride (PAC) inowanzoshandiswa pamwe chete mukugadzirisa mvura. Mumwe nomumwe ane maitiro akasiyana uye mabasa. Inoshandiswa pamwe chete kugadzira zvirinani kugadzirisa mhedzisiro.

1. Polyaluminium chloride(PAC):

- Main basa rakaita se coagulant.

- Inogona kunyatso kumisa kubhadharisa kwezvimedu zvakamiswa mumvura, zvichiita kuti zvimedu zviunganidzwe kuti zvigadzire maflocs makuru, anofambisa sedimentation uye kusefa.

-Inokodzera akasiyana emhando yemvura mamiriro uye ine mhedzisiro yakanaka pakubvisa turbidity, ruvara uye organic zvinhu.

2. Polyacrylamide(PAM):

-Basa guru rakaita se flocculant kana coagulant rubatsiro.

- Inogona kuwedzera simba uye huwandu hwefloc, zvichiita kuti zvive nyore kupatsanura kubva mumvura.

- Kune marudzi akasiyana-siyana akadai seanionic, cationic uye kwete-ionic, uye iwe unogona kusarudza rudzi rwakakodzera maererano nezvinodiwa zvekugadzirisa mvura.

Mhedzisiro yekushandisa pamwe chete

1. Kuvandudza coagulation effect: Iko kushandiswa kwePAC nePAM kunogona kuvandudza zvakanyanya coagulation effect. PAC inotanga kusandura zvimedu zvakamiswa mumvura kuti zvigadzire flocs, uye PAM inowedzera kuwedzera simba uye huwandu hweiyo flocs kuburikidza nebhiriji uye adsorption, zvichiita kuti zvive nyore kugadzirisa uye kubvisa.

2. Kuvandudza kushanda kwekurapa: Kushandisa PAC imwe chete kana PAM haigoni kuwana zvakanakisisa kurapwa, asi kusanganiswa kwezviviri kunogona kupa kutamba kwakakwana kune zvakanakira zvavo, kuvandudza kushanda kwekurapa, kupfupisa nguva yekuita, kuderedza kuyerwa kwemakemikari, nokudaro. kuderedza mari yekurapa.

3. Kuvandudza kunaka kwemvura: Kushandiswa kwakasanganiswa kunogona kunyatso bvisa zvakaturikwa zvakasimba, turbidity uye organic matter mumvura, uye kunatsiridza kujeka uye kuchena kwemhando yemvura yakasviba.

Chengetedzo Mukushanda Kunoshanda

1. Kuwedzera kutevedzana: Kazhinji PAC inowedzerwa pekutanga kune yekutanga coagulation, uye ipapo PAM inowedzerwa kune flocculation, kuitira kuti kuwedzere kuwirirana pakati pezviviri.

2. Dosage control: Chiyero chePAC nePAM chinoda kugadziriswa maererano nemamiriro ehutano hwemvura uye kurapwa kunoda kudzivisa tsvina nemigumisiro inokonzerwa nekushandisa zvakanyanya.

3. Kutarisa kwehutano hwemvura: Kuongororwa kwehutano hwemvura kunofanira kuitwa panguva yekushandiswa, uye kuyerwa kwemakemikari kunofanira kugadziriswa panguva yakakodzera kuti ive nechokwadi chekugadzirisa kurapa uye kunaka kwemvura.

Muchidimbu, iyo yakasanganiswa kushandiswa kwepolyacrylamide uye polyaluminium chloride inogona kuvandudza zvakanyanya kurapwa kwemvura, asi iyo chaiyo dosi uye nzira yekushandisa inoda kugadziridzwa zvinoenderana nemamiriro chaiwo.
