He aha ngā painga me ngā āhuatanga o te whakamaroke rehu polyaluminum chloride

🔬 I. Ngā painga o ngā āhuatanga ā-tinana me te matū

1. Āhua me te wairewatanga

• Hanganga matūriki pūwero: ko te hua i puta mai i te whakamaroke rehu he rite ki ngā matūriki pūwero, ki ngā matūriki tuwhera rānei, e whakanui ana i te horahanga whakapā ki te wai, ā, he tere ake te tere mākū i tērā o ngā hua paura, ā, he pai ake te wairewa.
• Rere pai: ngā matūriki ōrite, te mahi ātete puehu kaha, ngāwari ki te kawe me te tāpiri.
  2. Te pumau me te urutau
• Te pumau teitei: he pai te pupuri i te mahi a te hua, he kaha te pumau o te wera, ā, kāore e ngāwari te tango i te wai i te wā e rongoa ana.
• Whānuitanga pH urutaunga: pH e tika ana 5.0-9.0, ina koa ka iti te pāmahana wai, ka taea tonu te whakau i te flocculation.

⚡ 2. Ngā Painga o Te Whakamaemae Wai whai huatanga

1. Te kaha horoi tere

• He tere te tere o te waikura, ka taea te mimitiPākaHe kaha te wai, he nui, he kikī te para, ka piki te tere o te whakatōpuku mā te 30-50%, ā, ka tino heke te pōuri o te para.
• I raro i te kounga wai kotahi, ko te nui he 50% noa iho o te PAC whakamaroke pahu, inā koa mō ngā wai parahanga teitei.
  2. Pānga tukatuka hohonu
• Ka taea e ia te tango i te SS, te COD, te BOD me ngā konganuku taumaha (pērā i te arsenic, te mata, te mercury) ā, he tino kaha ki te tango tae.
• He iti iho i te 0.3% te nui o te mea kore-wai (hangarau tātari pereti me te anga) hei karo i te aukati i ngā paipa.

💰 E toru, ngā painga ōhanga me te whakahaere

1. Whakaitihia ngā utu katoa

• Ka whakaitihia te horopeta hei penapena i te utu o ngā kaihoko; he pai te mahi whakamaroke hei whakaiti i te taumahatanga o te maimoatanga paru.
• Ahakoa he nui te haumitanga ki ngā taputapu (tata ki te 5 miriona yuan), he iti ake te utu whakahaere mō te wā roa.
  2. Ngāwari ki te whakamahi
• Teitei o te aunoatanga, te whakaiti i te kaha o te mahi ā-ringa.
• Ka taea te tāpiri tika, te whakarewa rānei mō te whakamahi, he pai mō te mahi tonu i roto i ngā wāhi nui Te tipu waingā

🛡 Te haumaru me te tiaki taiao

1. Te haumarutanga teitei

• He iti ake te toenga o te tote konumohe, ā, he iti ake te pikinga o te nui o te tote i roto i te wai i muri i te maimoatanga, kāore he pānga ki te haumaru o te wai inu.
• E kore te nui rawa o te horopeta e whakararuraru, e whakapōrearea rānei i te kounga o te wai.
  2. Te whai pānga ki te tiaki taiao
• E whakamahia whānuitia ana i roto i te wai inu, i ngā wai para ahumahi (tā me te tae, whakakikorua hiko, hanga pepa), i ngā wai para o ngā tāone me ētahi atu mara, e ai ki te paerewa GB15892-2009.

⚖ Te whakataurite me te whakarāpopototanga ki ngā tukanga tuku iho

💎 Kua noho te polyaluminium chloride hei whakamaroke rehu hei rongoā pai rawa atu i roto i te mara o te maimoatanga wai nā te mea he pai te whakapūpū, he iti te whakamahinga me te tiaki taiao, ā, he watea hoki te whakahaere. He tino pai mō te wai inu me ngā wai para ahumahi me ngā whakaritenga kounga wai tino pakari.
