Coagulants - yintoni na le nto? Phi kwaye yintoni coagulants ezisetyenzisiweyo

Ukusetyenziswa kwamanzi acocekileyo kuphucula okukwazi impilo yabantu, ngaphandle nokuphola umzimba ngokwawo, esebenzisa oovimba alo. Eminyaka abantu bahlala kufutshane nemilambo kunye namachibi, besebenzisa ezo imithombo ukuba wanikela ubomi kwimvelo. Uninzi impucuko yamandulo sele esazi ukuba bazihlambulule amanzi ukuze izidingo zabemi ngokugqithisa esicwangciswe nodongwe kunye nesanti. Ngaloo mihla, abantu abazange ukusebenzisa coagulants (le nto, nto leyo yenziweyo unyango ephambili wamanzi anika ubomi namhlanje).

Ezifana namanzi ezahlukeneyo acocekileyo

Kwihlabathi lanamhlanje kucingwa ukuba, ngokuyinene, abantu kufuneka basebenzise emakhayeni abo iintlobo ezintathu amanzi:

• kufunyanwe amanzi elidluleyo ukucoca ezininzi umgangatho erhabaxa nocococ kwi abafuduki ezizodwa;
• nendlu, ngaphambili wayehambile ukuthintela isikali uluhlu izixhobo zokufudumeza osetyenziselwa ukuhlamba kunye nokuhlamba;
• ukusela, isetyenziswa kuphela yokufakwa nokupheka.

endlini amanzi Plain ibonelela inkqubo yonikezelo lwamanzi yasezidolophini. Kuba post-unyango self-ekhaya ngokusebenzisa izihluzi ezahlukeneyo, loo structuring kwenkqubo kwaye waqonda ukuba lulutho ezinye izimbiwa (ezifana shungite). Ukongeza, kukho coagulants, iintsholongwane amanzi ukusetyenziswa ekhaya.

Kwenzeka ntoni amanzi phambi kokuba bangene kombhobho

Phambi azinze kunye nama luvelise unyango lokuqala rough amanzi ekujongwe ukuba ubonelelo zamanzi zasezidolophini. Okokuqala, kwimigqomo ezizodwa ngokukhawuleza nokuxuba amanzi coagulant (ezi khemikhali ezizodwa). Xa coagulating isizathu electrostatic ye amasuntswana unyityilikiswa emanzini lifinyele, abaphumi kunye. Oku kube lula kwaye ikhawulezisa ukucocwa ngexesha ukulungisa kunye nama.

Inkqubo kwitanki omnye kuhlala malunga ngomzuzu. Ekubeni kunelixesha lokuphumla ezincinane ayiboneleli le ukufana efunekayo wokuxuba iziyobisi ngamanzi. Xa intsebenziswano elide lowanyathela floccules benziwa (kwenze slipshiesja amasuntswana angaphandle). Emva bedlula kwamatanki eziliqela apho coagulants amanzi agalelwe kulo ngomlinganiselo ngokuthe nokunciphisa, ulwelo phantsi neentlenge.

Yintoni igama elihle "flocculation"

Coagulants - ezi wezenzi imichiza. eziyingozi ezintweni babantu kuthathwa kwi ukuhluza eqhelekileyo ngexesha elifutshane Not onke. Ezinye zazo zikwimeko lichithakale. Ukuba elimsulwa abakhoyo emanzini okanye hydrosols, i coagulants unyango amanzi ngexesha yokuxhulumana kunye nabo uzakhela kwenze ezingenakunyibilika ngokohlobo a oluludaka. Inkqubo ukubunjwa amasuntswana agglomerated entle, i "iimfumba 'enkulu wabiza flocculation. Ubungakanani amasuntswana amatsha ungaba kuze ngemilimitha eziliqela.

Kakade ke, unako nyulu amanzi avela ubumdaka ezahlukeneyo ukuhluza njengesiqhelo, kodwa kuya kuthatha iminyaka eliqela, yaye eneneni zidinga amanzi yonke imihla yale mithi. Ukuze inkqubo wokucoca wayelele ngokwaneleyo kule ngabenzi zongezwa coagulants. Oku kunciphisa ukukhululwa okungeyomfuneko amanzi avela zonke izinto eziyingozi imizuzu 30-45. Nabahlali ngokukhawuleza kwizixeko needolophu bayakwazi ukusebenzisa ukuhlanganiswa amanzi zava kumakhaya abo.

Kwenzeka ntoni kwisityalo amdaka

Ngamanzi, nokuba sikhanya nje, ngokuqhelekileyo iqulethe isixa esikhulu ukungcola. Phakathi kwazo kukho ezi zinto zilandelayo:

• gypsum kunye netshokhwe;
• isanti, kunye nodongwe rocks;
• yl kunye ezincinane;
• hydroxides metal awonayo kancinane;
• iintsholongwane;
• iikhemikhali iyapheliswa;
• ukumiswa ezahlukeneyo.

amasuntswana esindayo enkulu esinobunzima eliphezulu ethile ngokufanelekileyo kuwa ngokukhawuleza ukuya ezantsi lamasetlani, imizuzu 1-2. Ukukhawulezisa inkqubo neentlenge (kwenze Ukuqulunqwa) amasuntswana ocoliweyo, elinokuthatha ukuya kwiminyaka emibini, amanzi kongezwa coagulants. Le chloride ferric, alumina sulphate, sulfate intsimbi, gidroksosulfaty hydroxychloride aluminium, umxube neetyuwa zentsimbi kunye aluminiyam, opacifiers ngodongwe, ukunqunyanyiswa flocculating ezahlukeneyo kunye brighteners.

Zokuhlanjululwa nengcaciso kwamanzi kwenkqubo ukulungisa nkqo kwi ilitha 1 ka-50 ukuya kwi-100 ml reagent. Yandiswe njo kunye yintshukumo kweekhemikhali amasuntswana colloidal kwenze, nto leyo ezahlulwe lula ngokuthi yokulungisa kunye nama.
