Chinokora Bhandi Regiravhiti
Zvinhu zvirimo
Yakakodzera mhando dzakasiyana dzetsvina, kunyangwe hunyoro huri mukati metsvina huri 99.6%.
Chiyero chekupora chakasimba chinopfuura 96%.
Kushanda kwakasimba pasina ruzha rushoma kana kuti pasina.
Kushanda uye kugadzirisa zviri nyore kunoita kuti hupenyu hurefu hwebasa huvepo.
Chinokora tsvina chinoita kuti chikobvu chiwedzere kunyangwe huwandu hwetsvina huchisiyana.
Kune simba guru rekubudisa zvinhu ne40% kupfuura mimwe michina ine nzvimbo yakafanana nepasi.
Mari yekuvaka, yekushanda, uye yevashandi inoderedzwa nekuda kwenzvimbo diki, chimiro chiri nyore, zvinhu zvishoma zvinodiwa pakuvaka uye kushanda kwega kwega.
Zvikamu
Chinosimbisa bhandi redu regiravhiti chinouya nemota yemagetsi yepamusoro, maroller, bhandi rekusefa, uye kuvakwa kwakasimba. Chinoiswawo nema nozzles esimbi isingatsvedzeri kuti chichenese bhandi panguva yekushanda, izvo zvinogona kuvimbisa kushanda kwechinhu chinosimbisa bhandi nguva dzose. Bhandi racho rinonamirwa nemasilinda emhepo otomatiki panguva yekushanda. Rinomanikidzwa kungave nemasipiringi emakanika ane mari shoma, kana nemasilinda emhepo kuti ashande otomatiki.
Nheyo yekushanda
Chinosimbisa sludge yebhandi regiravhiti chinoenderana nesimba regiravhiti kubvisa mvura kubva musludge kuburikidza nebhandi rimwe chete rakarukwa. Chekutanga, slurry neflocculating polymer zvinosanganiswa zvakaenzana mutangi rekugadzirisa. Zvinova floc granules dzakasimba dzinogona kubviswa mvura nyore nyore mushure mekuzungunuswa. Zvadaro, zvinoyerera munzvimbo yekudonhedza mvura.
Tsvina yakapwanyika inoparadzirwa zvakaenzana pabhandi rekusefa. Panguva yekushanda kwebhandi, mvura yakasununguka inobviswa kubva mutsvina negiravhiti kuburikidza nemeshi diki yebhandi rekusefa. Panguva yekufambisa tsvina, magejo akakosha anoramba achitenderedza uye achiparadzira tsvina muhupamhi hwebhandi. Mvura yakasara yakasununguka inobviswa zvakare kuti iite kuti tsvina iwedzere kukora. Nenzira iyi, thickener yebhandi rekukweva simba regiravhiti inobvumira nguva yekugadzirisa uye mwero wehuwandu hwemvura kuderedzwa zvakanyanya.
Mushure mekusefa, huwandu hwezvinhu zvakasimba zviri mumvura yakasununguka hunotangira pa0.5‰ kusvika pa1‰, izvo zvinoenderana zvakanyanya nemhando uye chiyero chepolymer yakatengwa.
