Ngophuhliso olukhawulezayo lwemizi-mveliso, ukukhutshelwa kwamanzi amdaka kwimizi-mveliso kuye kwanda unyaka nonyaka, nto leyo ebeka isoyikiso esibi kokusingqongileyo. Ukuze sikhusele indalo esingqongileyo, kufuneka sithathe amanyathelo asebenzayo ukunyanga la manzi amdaka. Njengeicoagulant ephilayo, I-PolyDADMAC ngokuthe ngcembe ibe sisisombululo esikhethiweyo sokunyanga amanzi amdaka amashishini.
Kutheni kucocwa amanzi amdaka kwimizi-mveliso?
Iingozi zamanzi amdaka kwimizi-mveliso azinakuhoywa. Amanzi amdaka aqulethe isixa esikhulu seeyoni zentsimbi enzima, iikhemikhali eziyingozi, ioyile, njalo njalo. Ezi zinto ziyingozi kakhulu kubomi basemanzini nakubantu. Ukukhutshwa kwamanzi amdaka angacocwanga ixesha elide kuya kukhokelela kungcoliseko lwamanzi, ukonakala kwendalo, kunye nezifo zabantu.
Ngokunyuka okuqhubekayo kwemveliso yemizi-mveliso, amanzi amaninzi amdaka akhutshelwa ngokuthe ngqo kokusingqongileyo ngaphandle konyango, ukonakalisa ngokunzulu ulungelelwaniso lwendalo kunye nokusongela impilo yabantu. Ngoko ke, kufuneka sithathe amanyathelo okunyanga amanzi amdaka avela kwimizi-mveliso ukunciphisa ifuthe lawo elibi kokusingqongileyo.
Kutheni ukhethaPolyDADMACukucocwa kwamanzi amdaka kwimizi-mveliso?
Ukujongana neengozi zamanzi amdaka kwimizi-mveliso, iindlela zonyango ezisetyenziswa ngokuqhelekileyo ziquka i-dosing ye-alum okanye i-PAC. Nangona kunjalo, ezi ndlela zemveli zihlala zineengxaki ezifana nomthamo omkhulu we-sludge, imisebenzi enzima, kunye neendleko eziphezulu. Ngoko ke, kufuneka sifumane indlela yonyango esebenzayo, eyongayo, kunye neyokusingqongileyo. Njenge-organic coagulant, i-PolyDADMAC ineempawu ezigqwesileyo ze-flocculation kunye ne-coagulation kwaye inokukhupha ngokukhawuleza nangokufanelekileyo izinto eziqinileyo ezimisiweyo (ezidla ngokuba ne-ion zentsimbi enzima kunye neekhemikhali eziyingozi) kumanzi amdaka. Xa kuthelekiswa neendlela zokucutshungulwa kwemveli, iPolyDADMAC ineengenelo zokusebenza ngokulula, ukusebenza kakuhle okuphezulu, umthamo ophantsi wodaka, kunye neendleko eziphantsi. I-PolyDADMAC iphinda isetyenziswe njenge-ejenti yokucoca i-sludge ukunciphisa umthamo wamanzi we-sludge obangelwa ezinye iinkqubo zoshishino.
Ingaba iPolyDADMAC iwaphatha njani amanzi amdaka akwimizi-mveliso?
Okokuqala, yongeza isisombululo esihlanjululweyo sePolyDADMAC kumanzi amdaka ngomlinganiselo othile kwaye udibanise ngokucokisekileyo ngokuvuselela. Ngaphantsi kwesenzo se-coagulant, izinto eziqinileyo ezimisiweyo kumanzi amdaka ziya kudibanisa ngokukhawuleza ukwenza i-particle flocs. Emva koko, ngamanyathelo onyango alandelayo afana ne-sedimentation okanye i-filtration, i-floc ihlukaniswe kumanzi amdaka ukuze ifezekise injongo yokucoca amanzi amdaka.
Xa usebenzisa i-PolyDADMAC ukunyanga amanzi amdaka emizi-mveliso, kufuneka ubeke ingqalelo kule miba ilandelayo. Okokuqala, kufuneka ukhethe umthengisi onomgangatho othembekileyo ukuqinisekisa ukuba i-coagulant ethengiweyo inomgangatho ofanelekileyo. Okwesibini, ngokwendalo kunye nokuxinana kwamanzi amdaka, idosi ye-coagulant kufuneka ikhethwe ngokufanelekileyo ukuphepha ukugqithisa okanye unyango olungonelanga olukhokelela kwiziphumo zonyango olubi. Ngelo xesha, umgangatho wamanzi amdaka ahlambulukileyo kufuneka uhlolwe rhoqo ukuze kuqinisekiswe ukuba imigangatho yokukhupha idibene. Ukongezelela, abaqhubi kufuneka bafumane uqeqesho lobuchwephesha kwaye baqhelane neempawu kunye nokusetyenziswa kwe-coagulants kunye nezilumkiso zokuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yokonyango.
Isishwankathelo, i-PolyDADMAC, njenge-coagulant esebenzayo kunye neyoqoqosho, ineenzuzo ezibalulekileyo ekuphatheni amanzi amdaka amashishini. Ngokusetyenziswa okunengqiqo kwePolyDADMAC, sinokunciphisa ngokufanelekileyo umonakalo wamanzi amdaka kwimizi-mveliso kwindalo esingqongileyo kwaye sikhusele ibhalansi yendalo kunye nempilo yabantu. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kolwazi lokusingqongileyo kunye nokuqhubela phambili kwezobuchwepheshe, i-PolyDADMAC iya kudlala indima ebaluleke kakhulu kwintsimi yokucoca amanzi amdaka.
