Muaj Aluminium Sulfate Yuav Ua Li Cas Rau Qhov Kev Tshem Tawm Txog Dej Khib

Lub luag hauj lwm ntawm Industrial Aluminium Sulfate heev, nws yuav ua tau ntxiv rau phosphorus, Xiao Bian rau txhua tus neeg los ua kom paub cov laj thawj.

Muaj Aluminium Sulfate nyob hauv chaw dej khib nyiab yuav raug siv rau kev tshem tawm phosphorus, uas yog vim nws muaj acidic, thiab acidic cov neeg ua hauj lwm nrog tus nqi paug ntawm cov kav dej phwj thiab mus txuas ntxiv rau kev tuav pov hwm. Lub carboxyl pawg yog tsim rau ib lub tshuab fab polynuclear carboxyl uas reacts nrog lub orthophosphate hauv dej los tsim ib lub phosphate precipitate kom tau cov nyhuv ntawm phosphorus tawm.

Phosphorus hauv dej khib nyiab yuav muab faib ua peb hom orthophosphate, ib nrab phosphorus thiab organic phosphorus. Qhov zoo phosphorus yog yooj yim reacted nrog txiv qaub, Muaj txhuas muaj hlau sulfate thiab thiaj li los tsim phosphate precipitates. Yog li ntawd, thaum cov tshuaj phosphorus raug tshem tawm ntawm cov dej khib nyiab, nws tau tshem tawm hauv dej xwb. Thaum lub phosphorus thiab phosphorus cov organic tsis yooj yim rau disengage dej, tsis nrog cov coagulant cov tshuaj tiv thaiv los tsim cov kab mob hauv pem teb. Hauv qhov no, hauv cov dej phwj haum, kev siv txoj kev biochemical, los ntawm microbial adsorption, degradation, hloov dua siab tshiab yuav hloov qoob phosphorus, organic phosphorus hloov mus rau orthophosphate mus cuag lub hom phosphorus tawm.

Rau phosphorus cov pa phem nyob rau hauv cov dej khib nyiab, peb yuav siv Industrial Aluminium Sulfate los tawm cov kev tshem tawm phosphorus, kom cuag cov kev kho tau zoo dua thiab txuag cov nqi.

Muaj Aluminium Sulfate thaum muaj kub, yuav kom ua tiav nws cov nyiaj pab ntau tshaj, cov nram no rau sawv daws tham txog:

Nws tau raug pom tias thaum kub kub qis dua 5 ° C, qhov ntsuas PST qis qeeb thiab nws lub cev molecular hloov ntawm lub xeev mus rau qhov chaw ruaj khov lossis tsis muaj zog. Thaum ntsuas qhov kub thiab txias yog 5-20 ℃, tus qauv ntawm Aluminium Sulfate yog qhov chaw ruaj khov tshaj plaws, tshwj xeeb tshaj yog li 20 ℃ dej kub, ua rau PAC khiav ceev, thiab kub ntawm -5 ℃, kev ua si, Tus nqi ntawm qhov kev lag luam qis qis dua, thiab qhov tshuaj tiv thaiv ntawm cov kuab paug hauv dej kuj qeeb, nws tsis yooj yim rau alum. Tsis tas li ntawd, dej kub dhau heev lawm yuav ua rau kom muaj dej txaus, ua rau lub zog flocculation qeeb qeeb, cov nyhuv rau qaug zog, floc nyuaj nyuab tsoo nrog sib, cohesion, alum particles fine.

Thaum lub caij ntuj sov no nyob rau sab qaum teb, koj tuaj yeem xaiv koom nrog lub chaw muag tshuaj thaum txog 10 teev sawv ntxov lossis ib ncig ntawm 3 teev tsaus ntuj. Thaum lub ntsuas kub siab dhau lawm, PAC khiav ceev, thiab cov dej paug dej ntau tuaj yeem ceev ceev, tsim cov flocs me me, muaj zog txaus, cov dej ntub dej noo muaj ntau dua, cov nqi kho cov dej ntws. Muaj Aluminium Sulfate kuj tseem nyob rau hauv kev kub siab inactivation, tsis tau ua si nws lub luag hauj lwm nyob hauv polymer flocculation. Yog li, thaum siv Cov Khoom Txhuas Muaj Kev Txhaum Cai, cov dej kub tuaj yeem tswj tau siab tshaj 5 ℃, dua li ntawm 20 ℃ -50 ℃, uas yog, tsis kub hauv lub cev, qhov kub siab, qhov khaus ntawm Brownian dua, .
