【Kukwezeleza Kuteteza Kwachilengedwe】 Chida chonse chamadzi a phosphorous chowunikira chokhazikika cha Shuanglong Sewage Treatment Plant ku Fuquan City "chayamba kugwira ntchito"!

Kuyang'anira ubwino wa madzi ndi imodzi mwa ntchito zofunika kwambiri pakuwunika zachilengedwe. Izo molondola, mwamsanga ndi mwatsatanetsatane zimasonyeza mmene zinthu zilili panopa ndi kachitidwe chitukuko cha khalidwe madzi, kupereka maziko sayansi kwa kasamalidwe madzi chilengedwe, kuipitsidwa gwero gwero, kukonza zachilengedwe, etc. Iwo ali ndi mbali yofunika kwambiri mu ndondomeko yonse ya madzi kuteteza chilengedwe, kulamulira kuipitsa madzi ndi kusunga thanzi la chilengedwe madzi.
Shanghai Chunye "yadzipereka kusintha maubwino ake azachilengedwe kukhala phindu lazachuma" monga nzeru zake zautumiki. Mabizinesi ake makamaka amayang'ana pa kafukufuku, kupanga, kugulitsa ndi ntchito zingapo zazinthu monga zida zowongolera njira zamafakitale, zida zowunikira madzi pa intaneti, VOCs (zowonongeka organic compounds) makina owunikira pa intaneti ndi makina owunikira a TVOC pa intaneti, Kutoleretsa kwa data pa intaneti, malo otumizira ndi kuwongolera, CEMS (Njira Yowunikira Yopitilira Kutulutsa, pa intaneti, kuyang'anira zida za mpweya, fumbi ndi zina.

Kulowa m'dera la fakitale la Shuanglong Sewage Treatment Plant, chida choyang'anira madzi a phosphorous chomwe changoyikira kumene ndi chochititsa chidwi kwambiri. Chidacho chili ndi mawonekedwe osavuta komanso owoneka bwino. Zida zikatsegulidwa, zida zowunikira akatswiri ndi magawo osungiramo reagent mkati zimawonekera bwino. Kukhazikitsidwa kwake kukuwonetsa kusintha kwakukulu kuchokera pakugwiritsa ntchito kwamanja komwe kunali kovutirapo kale kupita ku njira yowunikira komanso yanzeru yowunikira kuchuluka kwa phosphorous m'madzi onyansa.

Phosphorous yonse, monga chizindikiro chachikulu chowonetsera kuchuluka kwa eutrophication yamadzi, zomwe zimasintha zimakhudza kwambiri chilengedwe chamadzi. M'mbuyomu, njira yowunikirayi idadalira kugwiritsa ntchito pamanja, zomwe sizinangokhala ndi magwiridwe antchito ochepa komanso zinali ndi nthawi yocheperako pakupeza deta. Komabe, okwana phosphorous madzi khalidwe zodziwikiratu kuwunika chida akhoza kumaliza kusonkhanitsa deta, kusanthula, ndi zotsatira kufala mu nthawi yeniyeni ndi basi, kulola ogwira ntchito mwamsanga kumvetsa kusintha okwana phosphorous mu madzi oipa, kupereka maziko odalirika ndi nthawi yake ya kusintha ndi kukhathamiritsa njira zimbudzi mankhwala, potero mogwira mtima kuonetsetsa zotsatira mankhwala ndi kuteteza chilengedwe madzi.
