Unyango lwamanzi amdaka okucubungula iitapile: Izifundo zetyala lokukhupha amanzi amdaka

Isishwankathelo

Amanzi amdaka amdaka anezinto eziphilayo axineneyo kakhulu avela kwimisebenzi yokucubungula iitapile ngokunzulu adla ngokuhamba nemithamo emikhulu yedaka eliqinileyo elinomxholo wokufuma omalunga ne-85%. Olu daka kunzima ukuluthutha, lunokungcoliswa okwesibini, kwaye luthintelwe kwiindlela zokulahla amanzi ezisezantsi. Izifundo ezilandelayo zibonisa indlela imigca yokufunxa amanzi ekhoyo enokuphuculwa ngayo endaweni yayo—ngaphandle kokutshintshwa—ukunciphisa umxholo wokufuma kwedaka ukusuka kwi-85% ukuya ngaphantsi kwe-60%, ukujongana neenjongo zokuthobela okusingqongileyo kunye nokonga iindleko.

Isifundo seTyala 1 Iprojekthi yeHebei

Ishishini eliphambili lesizwe lokucoca iitapile eHebei livelisa amanzi amdaka angama-3,000 m³ ngosuku, kunye nobuninzi obukhulu bodaka oluqinileyo olune-85% yomthamo wokufuma. Inkqubo edibeneyo edibanisa umatshini wokuqala wokukhupha amanzi kunye nomatshini wokucindezela ibhanti oxinzelelo oluphezulu yamkelwe. Ngaphandle kokutshintsha inkqubo yokukhupha amanzi ekhoyo, imodyuli yokukhupha amanzi enzulu yafakelwa ukucinezela umxholo wokufuma kodaka ukusuka kwi-85% ukuya ngaphantsi kwe-60% kwinqanaba elinye.

Oomatshini bokuqala bokususa amanzi be-screw press bavelisa udaka olumalunga ne-85% yomthamo wokufuma, into ebhityileyo, efana ne-paste engafanele ukuthutha ngqo ngaphandle kwendawo. Iindleko zothutho zaziphezulu, ungcoliseko lwesibini lwaluyingozi, kwaye iindlela zokulahla ezisezantsi zazilinganiselwe. Eli shishini lijongene nengxaki yokutshintsha zonke izixhobo kuya kufuna utyalo-mali olukhulu, ngelixa ukungathathi nyathelo kuya kwenza kube nzima ukuhlangabezana neemfuno ezingqongqo zokusingqongileyo. Isisombululo esicetywayo yayikukuphucula endaweni ngaphandle kokudilizwa nokungatshintshwa. Kusetyenziswa imveliso ye-screw press ekhoyo, inkqubo entsha yokususa amanzi anzulu yohlobo lwebhanti yoxinzelelo oluphezulu yongezwa kwaye yadibaniswa ngokungenamthungo nomgca wemveliso okhoyo. Ngaphandle kotshintsho olupheleleyo kwiindlela zokusebenza ezimiselweyo, umxholo wokufuma kodaka wehliswe ngokuthembekileyo ukusuka kwi-85% ukuya ngaphantsi kwe-60%.

Isifundo seTyala 2 Iprojekthi yeNingxia

Umzi-mveliso oseGuyuan, eNingxia, ugqibezele umsebenzi ofanayo. Iprojekthi yaseGuyuan iphatha amanzi amdaka angama-4,000 m³d kwaye isebenzisa umatshini wokukhupha amanzi amdaka ofana nebhanti enoxinzelelo oluphezulu, ikwanciphisa umxholo womswakama wodaka ukusuka kwi-85% ukuya ngaphantsi kwe-60%.

Ukuhamba kweNkqubo

1. I-screw press ekhoyo njengesigaba sokuqala. I-screw press ekhoyo yesityalo isebenza ngokuqhelekileyo, isusa amanzi kwi-sludge ukusuka kwi-98% yomthamo wokufuma ukuya kwi-85%. Ikhekhe eliphumayo liwela ngqo kwi-sludge buffer hopper entsha eyongeziweyo.
2. Ukutya okunemilinganiselo kunye nokulungiswa kwesimo somzimba. Inkunkuma emanzi inikwa ngesantya esilawulwayo ukusuka ezantsi kwehopper yi-conveyor enezikrufu ezimbini ukuya kwiyunithi yokulungisa inkunkuma, apho abakhi be-skeleton kunye nabakhuthazi batyathwa ngaxeshanye. Inkunkuma elungisiweyo emva koko ingena kumatshini wokukhupha amanzi ohlobo lwebhanti enoxinzelelo oluphezulu, idlula ngokulandelelana kwiindawo ezine zokucinezela—uxinzelelo oluphantsi, uxinzelelo oluphakathi, uxinzelelo oluphezulu, kunye noxinzelelo oluphezulu kakhulu—apho amanzi acocwa khona aze ahlulwe ngokuthe chu. Umxholo womswakama uhlala uncitshiswa ube ngaphantsi kwama-60%. Iibhanti zesihluzo zixhotyiswe ngezixhobo zokuhlamba eziqhubekayo, kwaye amanzi okuhlamba abuyiselwa kwinkqubo yokucoca amanzi amdaka ukuze ajikeleziswe kwakhona, ukuqinisekisa ukuba akukho ngcoliseko yesibini kuyo yonke inkqubo.

Iingenelo zeSisombululo

- Unyawo oluncinciI-retrofit isebenzisa ngokuthe ngqo isakhiwo se-workshop esikhoyo, ingadingi lwakhiwo olongezelelweyo lwesakhiwo, nto leyo enciphisa kakhulu iindleko zobunjineli bokwakha kunye nexesha lokwakha.

- Ukuhlanganiswa okungenamthungoIzixhobo zokukhupha amanzi ezinzulu ezisandul’ ukongeza ziqhagamshelana kakuhle noomatshini bokuqala bokukhupha amanzi abakhoyo kwindawo, zicubungula ngokuthe ngqo udaka olumalunga ne-85% yomthamo wokufuma kwaye zonga imali kwizixhobo.

- Ukusebenza okuqhubekayo, okuzenzakalelayo ngokupheleleyo. Le nkqubo isebenza iiyure ezingama-24 ngosuku ngolawulo olukrelekrele lwe-PLC. Iiparameter zokusebenza kunye nemilinganiselo yokulinganisa iikhemikhali zinokukhethwa ngokweempawu zodaka, okuvumela ukulungiswa okuqhubekayo, ukuxuba, ukukhupha amanzi kwi-extrusion, kunye nokukhupha. Le nkqubo inika ukusebenza okuzinzileyo, okuthembekileyo, nokuqhubekayo ngokuphathwa okulula kunye nesantya esiphantsi sokusilela.
