Aluminium Sulfate Inoshandiswa muSewage Phosphorus Removal

Aluminium sulfate inowanzo shandiswa semunatsi wemvura ine turbid.Iko kushandiswa kwayo kwakanaka kwazvo, nekuti kune akawanda masewages ane yakakwira phosphorus content, izvo zvinokonzeresa kusvibiswa kwemvura.Kuti udzivise kusvibiswa, mabhizinesi mazhinji ikozvino Ichashandiswa kubvisa phosphorus mumvura yetsvina, saka ndeipi mhedzisiro yayo, ngatitarisei kunotevera kuedza.

1. Wedzera

Wedzera 25% yehuwandu hwemhinduro kune sewage treatment system, wedzera nguva dzose kweinenge mwedzi, uye edzai mhedzisiro yekuwedzera, iyo phosphorus yemukati mesuwage pasina kurapwa, uye phosphorus yemukati mushure meiyo microbial phosphorus kubvisa kurapwa kuchawedzera ne25. % Iyo phosphorus yemukati yemvura yakaburitswa mushure mekurapwa kwemhinduro ine huwandu hwakanyanya hwakaitwa, uye nhevedzano yekuenzanisa miedzo yakaitwa.Maererano nemigumisiro yekuedza, tinogona kuziva kuti kana nzira yehutachiona chete inoshandiswa kubvisa phosphorus muhutano hwekugadzirisa tsvina, iyo phosphorus inowanikwa mumvura yakagadziriswa inogona kutoderera nekuda kwechiitiko che hysteresis.Iyo phosphorus yemukati yakakwira kupfuura iyo yezuva, uye iyo phosphorus yekubvisa mhedzisiro haina kukosha, asi kuwedzera aruminiyamu sulfate senge precipitant inogona kubvisa yakawanda phosphorus mumvura yetsvina, ichiita kushayikwa kweiyo microbial phosphorus yekubvisa kugona.Zvinogona kutaurwa kuti zvechinyakare microbial phosphorus kubviswa A simba rekuwedzera kune nzira, zvinogona kutaurwa kuti zvinokosha zvikuru phosphorus kubviswa tsvina.Inogona kukurumidza kubvisa phosphorus munguva shoma shoma, uye inogadzirisa matambudziko anotevera eiyo microbial nzira.

2. Sarudza kusungirirwa kwemhinduro

Kuti titarise iko kwakaringana kwemhinduro se phosphorous precipitating agent, takaita ongororo uye kuenzanisa pamvura inonaya ye15% concentration solution, 25% concentration solution, uye 30% concentration solution.Zvinogona kugumiswa kuti mhinduro ye15% yekusungwa Mhedzisiro yekurapa kwetsvina ine yakakwira phosphorus yezvinhu dzimwe nguva haisi pachena, asi mhinduro ine huwandu hwe25% inogona kubvisa yakawanda ye phosphorus mumvura yetsvina, uye kushanda kwemhinduro ne kuungana kwe30% kwakafanana neiyo ye25%, saka sarudza 25% % yeconcentration solution inonyanya kukodzera phosphorus kubvisa precipitant.

3. Kusimbiswa kwekugadzikana kwekubvisa phosphorus

Kuti tiratidze kuti phosphorus yayo yekubvisa mhedzisiro haina kugadzikana, isu takawedzera 25% mhinduro kune sewage treatment system yekuyedza phosphorus yekubvisa mhedzisiro kwenguva yakareba.Munguva yekurapa, iyo phosphorus kubvisa mhedzisiro yakakosha uye yakanyanya kugadzikana.Kutariswa kwenguva refu kweiyo phosphorus mukati memvura yakabatwa uye yakabviswa zvese zvinoenderana nerudzi rwesecondary sewage treatment discharge standard, uye yakavimbika kwazvo kuishandisa pakubvisa phosphorus.

Mukuedza kuri pamusoro apa, tinogona kuona kuti mhedzisiro yekugadziriswa kwetsvina yakajairika haina kusimba, uye mhedzisiro yekushandisa aluminium sulfate kurapa phosphorus mutsvina yakanaka kwazvo, asi kugadzikana kwakanaka kwazvo, uye nzira yekurapa zvakare iri nyore kwazvo. .
