Mai i tōna whakatūnga, kua piri pūmau te Kamupene Taiao o Liancheng ki te rapunga hokohoko o te arotahi ki te kiritaki me te kaupapa matua, ā, nā roto i te mahi maha-rōpū roa hei tūāpapa, kei reira ngā "Liancheng" pukumahi i ngā wāhi hangarau puta noa i te motu. I te tīmatanga o Mei, i tukuna e tētahi tari whakamātautau i Hubei tētahi pūrongo whakamātautau mō te tauira wai i tukuna e Hubei Lomon Phosphorus Chemical Co., Ltd. I whakaatuhia e te pūrongo ko te ihirangi totoka i whakatārewatia (SS) i roto i te tauira wai i whakamatautauria he 16 mg/L, ā, ko te ihirangi phosphorus katoa (TP) he 16 mg/L. ko te 0.02mg/L, ā, ko te ihirangi makuku o te paru kua whakamarokehia he 73.82%. E ai ki ngā hua whakamātautau, i whakatauhia ko ngā taputapu maimoatanga wai whakakotahi aukume LCCHN-5000 i hangaia me te tuku mai e tā mātou kamupene mō Hubei Lomon Phosphorus Chemical Co., Ltd. he tohunga ki te hoahoa me te whakahaere, he nui atu i ngā tohu e hiahiatia ana e ngā kiritaki. He tino pai te kounga o te āhua o ngā taputapu, ā, he tohu anō hoki tēnei kei a Liancheng te tauira kaupapa tuatahi i te rohe o Hubei.
Ngā tohu mō te wai mata me te wai kua tukatukahia me te whakatairite i ngā hua tuturu
I te tīmatanga o Hepetema 2021, whai muri i te whiwhinga o ngā whakaritenga hangarau e tika ana i whakaratohia e te kiritaki, i hanga tuatahi e te Kaiwhakahaere Qian Congbiao o te Tari Tuarua o Liancheng Environmental Sewage tētahi mahere mō ngā taputapu maimoatanga whakauru o te tukanga flocculation + sedimentation + filter, engari nā ngā āhuatanga mahi motuhake i te papaanga, kāore i taea e te rahi o ngā taputapu i hangaia tuatahi te whakatutuki i ngā āhuatanga hanga ā-iwi. Whai muri i te kōrero ki te kiritaki, i whakatau te Kaiwhakahaere Tang Lihui o te Tari Tari Wai Para i tētahi mahere hangarau mō te maimoatanga o te wai para mā te coagulation aukume. Nā te kore o te wā, kāore i taea e ngā kaimahi hangarau o te tari matua te tae atu ki ngā whakawhitiwhiti hangarau. I whakapā atu tā mātou tari ki te kiritaki hei whakaū, ā, i whakahaerehia ngā whakawhitiwhiti hangarau mamao mā te aratau hui whatunga. Whai muri i te whakaurunga taipitopito o te mahere a tā mātou kamupene e te Kaiwhakahaere Tang, i whakaaetia katoatia e te kiritaki, ā, i whakatauhia i te mutunga ko te 5000 tana/rā te kaupapa maimoatanga wai para toka phosphate e whakamahi ana i tētahi huinga taputapu maimoatanga wai coagulation aukume whakauru, he 14.5m te roa, he 3.5m te whānui, he 3.3m te teitei.
He māmā noa te tāuta i ngā taputapu, ā, he ngāwari hoki te whakamahi. Whai muri i te taenga ki te papa mahi i te 13 o Poutū-te-rangi, ka tīmata te whakarewatanga o te wai me te hiko i te 16 o Poutū-te-rangi. E rua ngā rā i muri mai, kua eke ngā taputapu ki te āhua mahi aunoa katoa, ā, ka taea te whakarerekē me te whakatakoto i ngā tawhā mahi o ngā taputapu mai i tawhiti mā te tūāpapa atamai. He tūāpapa tuku aroturuki ataata mō te āhua o te mahi i roto i te rūma taputapu, kātahi ka tukuna mai i ngā waea pūkoro, ngā rorohiko me ētahi atu pāpāho maha. Whai muri i te rā mahi aunoa, kua eke te whakamātautau tuatahi o te kounga wai para o ngā taputapu ki te paerewa i te ata o te 19, e tatari ana kia whakaaetia te kaupapa.
Mā te aroturuki me te mārama ki te tukanga i mua i te hoko, i roto i te hoko me muri i te hoko o te kaupapa, ka taea e tātou te tino mārama ko te maimoatanga wai whakakotahi aukume whakauru a Liancheng he āhuatanga o te whakaurunga taputapu, te matauranga me te whakauru matauranga, ā, kāore te tāutanga me te patuiro taputapu e pāngia e te huarere pēnei i te pāmahana. , e tika ana mō te whānuitanga o ngā taiao, te haumitanga hangarau ā-iwi iti me te wā hanga poto, te tāutanga me te tono taputapu tere, te tapuwae iti me te maha atu o ngā āhuatanga.
Whakataki tukanga：
Ko te hangarau whakapūmautanga o te whakapūmautanga aukume (whakapūmautanga tino whai hua) he tāpiri i te paura aukume me te taumaha motuhake o te 4.8-5.1 ki roto i te tukanga whakapūmautanga me te whakapūmautanga tuku iho, kia uru atu ai ki te whakapūmautanga o ngā poke, kia kaha ake ai te pānga o te whakapūmautanga me te whakapūmautanga, kia matotoru ake ai, kia kaha ake ai te tinana papura e puta mai ana, kia tutuki ai te kaupapa o te whakapūmautanga tere-teitei. Ka taea e te tere taunga o ngā whakapūmautanga aukume te eke ki te 40m3/h, neke atu rānei. Ka hangarua te paura aukume mā te mīhini kutikuti teitei me te wehewehe aukume.
He poto rawa te wā noho o te tukanga katoa, nō reira, mō te nuinga o ngā poke tae atu ki te TP, he iti rawa te tūponotanga o te tukanga ārai-rewa. Hei tāpiri, he kino te paura aukume me te flocculant e tāpirihia ana ki te pūnaha ki ngā huakita, ngā huaketo, te hinu me ngā matūriki ririki. He pai te pānga mimiti, nō reira he pai ake te pānga tango o tēnei momo poke i tērā o te tukanga tuku iho, inā koa he mea nui ngā pānga tango phosphorus me te tango SS. Ka whakamahia e te hangarau flocculation coagulation aukume (he nui te whai huatanga o te rerenga) te paura aukume o waho hei whakarei ake i te pānga flocculation me te whakapai ake i te whai huatanga o te rerenga. I taua wā anō, nā te tere o te rerenga, he maha ngā painga pērā i te tere teitei, te whai huatanga teitei me te iti o te tapuwae ki te whakataurite ki ngā tukanga tuku iho.
Ngā Āhuatanga：
1. He tere te tere o te whakataunga, ka eke ki te tere whakataunga teitei o te 40m/h;
2. Te kawenga mata teitei, tae atu ki te 20m³/㎡h~40m³/㎡h;
3. He poto te wā noho, tae noa ki te 20 meneti mai i te tomokanga wai ki te putanga wai (i ētahi wā, ka poto ake te wā noho);
4. Ka whakaitihia te wāhi papa, ā, ko te wāhi papa o te tāke whakatō parahanga ka taea te iti iho i te 1/20 o te tukanga tikanga;
5. He pai te tango i te whākawa, ko te TP para pai rawa atu ka taea te iti iho i te 0.05mg/L;
6. Te māramatanga o te wai, te pōuri <1NTU;
7. He teitei te tere tango o te SS, ā, ko te para pai rawa atu he iti iho i te 2mg/L;
8. Te hangarua paura aukume, ko te tere whakaora he neke atu i te 99, ā, he iti te utu whakahaere;
9. Te arotau i te horopeta o ngā rongoā, te whakaiti i ngā utu whakahaere, me te penapena i te 15% o te horopeta i te wā pai rawa atu;
10. He kiato te pūnaha (ka taea hoki te hanga hei taputapu tukatuka pūkoro), ka taea te whakahaere aunoa, ā, he ngāwari hoki te whakahaere.
He hangarau hou whakaharahara te hangarau whakatōtō aukume. I mua, kāore i te maha te whakamahinga o te hangarau whakatōtō aukume i roto i ngā kaupapa maimoatanga wai, nā te mea kāore anō kia tino whakatauhia te raruraru o te whakaora paura aukume. Ināianei kua angitu te whakatau i tēnei raruraru hangarau. Ko te kaha o te papa aukume o tā mātou wehewehe aukume he 5000GS, koinei te mea tino kaha i Haina, ā, kua eke ki te hangarau matua o te ao. Ka taea e te tere whakaora paura aukume te eke ki te neke atu i te 99%. Nō reira, ka whakaatahia katoatia ngā painga hangarau me te ōhanga o te tukanga whakatōtō aukume. Kei te whānui haere te whakamahinga o te tukanga whakatōtō aukume i te kāinga me tāwāhi mō te maimoatanga paru o ngā tāone, te whakamahi anō i te wai kua whakahokia mai, te maimoatanga wai mangu me te wai kakara awa, te maimoatanga Parapara nui te ūkuikui, te maimoatanga paru para hanga pepa, te wai para whenua hinu, te maimoatanga paru maina me ētahi atu mara.
