Penda mhute coagulant
Inoshanda Ongororo
Iyo pendi-yemvura pendi inonetsa kupatsanurwa kubva kumvura nekuda kwekusanzwisisika kwayo nemvura, uye inogadzira furo yakawanda, iyo inokanganisa kugadzirwa. Mvura-yakavakirwa pendi mhute coagulant imhando yemakemikari mumiriri mbichana zvinhu zvakanyanyo shandiswa kugadzirisa kurapwa kwemvura-yakavakirwa pendi tsvina mvura uye kubviswa kwepende (pendi slag) mukutenderera kwemvura. Mvura-yakavakirwa pendi mhute coagulant chinhu chakajairika chinowedzerwa chekurapira kurapwa kwekutenderera kwemvura muindasitiri yependi. Basa guru nderekubvisa viscosity yemhute yependi, kumonyorodza mhute yependi kuita floc uye kuiyangisa pamusoro pemvura inotenderera, iri nyore kununura nekubvisa (kana otomatiki kudzora slag kubviswa).

1. Kuora uye kubvisa iyo viscosity yekudonha pendi mumvura inotenderera yemhando dzakawanda dzemaketeni emvura ekuparadzira matumba. |
2. Coagulate uye kumisa zvakasara zvepende |
|
3. Chengetedza hutachiona hwekutenderera kwemvura uye chengetedza mhando yemvura |
4. Kusimudzira hupenyu hwebasa rekutenderera kwemvura, kudzikisa mutengo wekuchenesa tangi nemvura |
|
5. Natsiridza emvura yakasviba biochemical kurapwa kugona uye kudzikisa emvura yakasviba yekurapa |
6.Pendi slag haina-kunamira uye isina kunhuwirira, nyore kushayisa mvura mumuviri uye kudzikisa mutengo weiyo yakaraswa slag |
|
7. Chengetedza kuwanikwa uye kupedza chiyero, kugadzirisa kugadzirwa kwekugadzira, kuona mhando yechigadzirwa, uye kudzikisa mutengo wekugadzira |
8.Pendi yekupfira kamuri iri nyore kuchenesa nekuchengetedza, kuwedzera hupenyu hwebasa uye kudzikisa michina yekutsiva mutengo |
|
9. Kuvandudza nharaunda yekushandira yechipfira imba uye kugona kwebasa |

Mirayiridzo Yekutarisa
Mvura-yakavakirwa pendi mhute coagulant yakakamurwa kuva mumiriri A uye mumiriri B. Iwo maairi maviri anoshandiswa pamwechete (kazhinji chiyero cheavo vamiririri A naB ndi3: 1-2). Kutanga wedzera imwe yakamiririra mumiririri A (kazhinji 2 ‰ yeuwandu hwependi inotenderera mvura) mupendi inotenderera mvura. Mumiriri A anowedzerwa panopinda mvura inopararira, uye mumiriri B anowedzerwa panobuda mvura inotenderera yekupenda (vamiririri A naB havafanirwe kuwedzerwa panzvimbo imwechete panguva imwe chete). Kazhinji, iyo muyero weanomiririra ndeye 10-15% yehuwandu hwekuwedzererwa. Kazhinji, mumiriri anokwanisa kuwedzerwa nemaoko kana otomatiki nepombi yemetering. Zvinoenderana nehuwandu hwekunyanyisa, kuyerera uye kuyerera kwepombi yekumeta kunogona kugadziridzwa.
| kutaurwa | chitarisiko | Kuwedzera (20 ° C) | PH (10g / L) | Refractive indekisi (20 ° C) |
| A-mumiririri | namira-semvura | 1.08 ± 0.02 | 7 ± 0.5 | 1.336 ± 0.005 |
| B- mumiririri | Viscous mvura | 1.03 ± 0.02 | 6 ± 0.5 | 1.336 ± 0.005 |
Mirayiridzo
1. Zvinokurudzirwa kuchenesa tangi zvachose uye nekushandura mvura kamwe usati washandisa mumiriri, kuitira kuti maitiro ave nani. Mushure mekushandura mvura, tanga wagadzirisa mhando yemvura ine sodium hydroxide kudzora 8-10PH kukosha renji, uye wedzera 1.5-2.0 kg pa ton yemvura Around sodium hydroxide.
2. Wedzera pendi mhute flocculant A kune isina kugadzikana kutenderera kwemvura kwenzvimbo yekupfapfaidza mangwanani ega ega mushure mekushandurwa kwemvura (kureva., Pfupa booth pombi mota); mushure mekuwedzera mushonga, gadzira uye pfapfaidza pendi senguva dzose, uye wedzera pendi mhute flocculant B pamberi pebasa. Iyo pendi yakasara inowanzo sungwa (ndokuti, iyo pendi tangi tangi); zvakasara zvependi zvakamiswa zvinogona kununurwa mushure mekushanda.
3. Dosing ratio: Iyo dosing reshiyo yependi inobvisa uye inomisa mumiririri ndeye 1: 1, uye nguva yega yega huwandu hwependi hwakasimudzwa mumvura inotenderera yechipfira imba inosvika 20-25 kg, wedzera 1 kg imwe neimwe. (Iyi reshiyo ndeye pre-inofungidzirwa kukosha. Iyo chaiyo dosi inoda kugadziridzwa zvishoma zvichienderana nerudzi rwependi uye viscosity panzvimbo. Nekuti iro rekare pendi block adsorbed mune yekupfira kamuri pombi ichadya chikamu chemushonga, saka huwandu Yezvinodhaka inoshandiswa munguva yekutanga yedhosi inofanira kunge iri diki. Yakakura kwazvo)
4. Hapana chikonzero chekugadzirisa PH kukosha.
Kubata uye kuchengetedza
1. Dzivisa kumwaya mvura mumaziso. Kana ukasangana neiyo mvura, nekukasira svinura nzvimbo yekubatana nemvura yakawanda.
2. Chengeta pendi flocculant AB munzvimbo inotonhorera uye dzivisa zuva rakananga.
3. Haigone kuchengetwa mune alloys yealuminium, iron uye mhangura.
