Coagulants - chii ichi? Kupi uye chii coagulants anoshandiswa

Kushandiswa kwemvura yakachena kunonatsiridza utano uye munhu kutapata, kunze kuwana muviri pachawo, vachishandisa reserves ayo. Vanhu kwemazana emakore vakagara pedyo nenzizi uye nyanza, kushandisa avo matsime kuti akapa upenyu zvakasikwa. Most mararamiro ekare kare vaiziva sei kunatsa mvura zvinodiwa vagari nokuisa nayo kuburikidza akaturikidzana dzevhu uye jecha. Mumazuva iwayo, vanhu havana kushandisa coagulants (fuma iyi, iri zvinoberekwa chikuru mabatiro mvura inopa upenyu-nhasi).

mvura kwakadaro siyana yakachena

Munyika yanhasi iri kukurukurwa kuti, Zvakanakisa, vanhu vanofanira kushandisa mudzimba dzavo nhatu mhando mvura:

• vawane mvura yakapfuura mureza akawanda zvinonyadzisa kuchenesa uye mupise chaihwo kugara;
• mhuri, kare akanyevenutsa kudzivirira pamwero inotungamirwa mu kudziyisa midziyo yemagetsi anoshandiswa Washing pakushambwa;
• achinwa, rinoshandiswa chete ingestion uye kubika.

Plain mvura furati kunopa madhorobha mvura hurongwa. Nokuti kuzvicheka-musha post-kurapwa vachishandisa filters siyana, kuti yokuronga patsva gadziriro uye vakaziva kushanda nevamwe zvicherwa (akadai shungite). Uyezve, pane coagulants, disinfecting mvura nezvezvipfuwo kushandiswa.

Chii chinoitika kuti mvura vasati vapinda nenyere

Asati agadzirisa uye filtration aigadzira rokutanga ine mabatiro mvura aida kuti wedzerai mumadhorobha mvura enyika. Chokutanga, mune chaiyo midziyo kukurumidza kuvhenganisa mvura uye coagulant (dzinokosha makemikari). Kana coagulating ari electrostatic kuvenga of nezvimedu zvazvichanyungudutswa mumvura ipfupi, akanamatirana pamwe chete. Izvi hwezvekukurukurirana uye zvinoita kuti ukurumidze kuchenesa panguva nyaya uye filtration.

The kwacho rimwe tangi anofanira kugara pamusoro imwe miniti. With duku nguva penguva haripi runodiwa kufanana kusanganiswa nefuma nemvura. At yakareba kudyidzana anogona kutyora floccules vakaumba (precipitate slipshiesja nezvimedu vatorwa). Mushure vagura Matangi akawanda apo coagulants mvura yakasanganiswa paro zvishoma nezvishoma kudzikira zvazvingava, mvura iri pasi sedimentation.

Chii ishoko rakanaka "flocculation"

Coagulants - vane makemikari reagents. Havasi vose vane kukuvadza munhu zvinhu zvinogona hwokurara senguva dzose filtration munguva pfupi. Vamwe vavo vari kudaro mamiriro. Kana nouipi varipo mumvura kana hydrosols, kuti coagulants kunorapwa mvura panguva nekuita navo iumbe insoluble precipitate ari muchimiro slurry. Pfungwa inotungamirwa agglomerated yakaisvonaka inoramba, makuru "mirwi" uye anonzi flocculation. Ukuru nezvimedu itsva inogona kusvika millimeters wandei.

Chokwadi, unogona kunatsa mvura pakusachena siyana zvatinosiita filtration, asi achatora makore akawanda, uye mune chokwadi vanoda mvura zuva nezuva huru akawanda. To rokutsvaira anga makasimba zvakakwana ari mixers anowedzerwa coagulants. Izvi zvinoderedza zvisingakoshi kusunungurwa mvura dzose zvinokuvadza kuti maminitsi 30-45. With nokukurumidza vaigara mumaguta nemisha vanokwanisa miganhu kushandisa mvura kubva muutefetefe yavo.

Chii chinoitika panguva tsvina chirimwa

In mvura, kunyange usiri pane imwe aitarire, kazhinji rine yakawanda tsvina. Pakati pavo pane zvinotevera zvinhu:

• gypsum uye nesuko;
• jecha nevhu matombo;
• yl uye plankton;
• zvishoma soluble simbi hydroxides;
• mabhakitiriya;
• ichiputswa makemikari;
• siyana kuturika.

Heavy uye makuru nezvimedu rurefu chaizvo guru nokururamisira nokukurumidza harungawiri pasi anobva, kwemaminitsi 1-2. Kuwedzera pamusoro sedimentation muitiro (precipitate inotungamirwa) pamusoro nezvimedu yakaisvonaka, iyo inogona kugara makore maviri, mvura chakawedzerwa coagulants. Ichi ferric chloride, sulphate alumina, simbi sulfate, gidroksosulfaty hydroxychloride uye aruminiyamu, musanganiswa wesimbi uye aruminiyamu munyu, ivhu opacifiers, zvakasiyana flocculating kuturika uye brighteners.

Nokuti yokunatsa uye kujekeswa nemvura ezvinhu wehunyambiri nyaya musi 1 fő 50 kusvika 100 ml reagent. Wakakurisa uye glued pamwe kuitwa mishonga colloidal nezvimedu precipitate, mamwe nyore dzakaparadzaniswa pakugadzirisa uye filtration.
