Ko te kōhatu puia (e mōhiotia whānuitia ana ko te pumice, ko te basalt porous rānei) he rauemi whai hua, he rauemi taiao hoki, he kōhatu porous tino utu nui i hangaia e te karāhe puia, ngā kohuke, me ngā mirumiru i muri i te pahūtanga o te puia. Kei roto i te kōhatu puia he maha ngā kohuke me ngā huānga iti pēnei i te konutai, te konupūmā, te konumohe, te silicon, te konupūmā, te titanium, te manganese, te rino, te nickel, te cobalt, me te molybdenum. Kāore e pā te hihi, ā, he ngaru aukume infrared tawhiti. Whai muri i te pahūtanga o te puia nanakia, whai muri i ngā tekau mano tau, kei te piki haere te kitea e te tangata tōna uara. Kua whānui ake ōna mara tono ki ngā mara pēnei i te hoahoanga, te tiaki wai, te huri, ngā rauemi tātari, te waro tunutunu, te whakapaipai whenua, te whakatipu kore oneone, me ngā hua whakapaipai, ā, he mahi nui tēnei i roto i ngā momo ahumahi.

Ko te mahi a ngā toka puia ko te 1: te wai hohe. Ka taea e ngā toka puia te whakahohe i ngā katote i roto i te wai (mā te whakanui ake i te nui o ngā katote hāora) ā, ka taea te tuku paku i ngā hihi-A me ngā hihi whero-whero, he mea whai hua mō ngā ika me ngā tāngata. Kāore e taea te wareware i te pānga patu huakita o ngā toka puia, ā, mā te tāpiri atu ki te puna ika ka taea te ārai me te rongoā i ngā tūroro.

Ko te mahi a ngā toka puia he whakau i te kounga o te wai.

Kei roto hoki i tēnei ko ngā wāhanga e rua: te pumau o te pH, ka taea te whakarite i te wai he waikawa rawa, he kawakore rawa rānei kia tata aunoa ki te koretake. Ko te pumau o te ihirangi kohuke, he āhuatanga rua ngā toka puia o te tuku i ngā huānga kohuke me te mimiti i ngā paru i roto i te wai. Ina iti rawa, ina nui rawa rānei, ka puta tōna tukunga me te mimiti. He mea nui te pumau o te uara PH o te kounga wai i te tīmatanga o te Arhat me te wā e tae ana.

Ko te mahi a ngā toka puia he whakaputa tae.

He kanapa, he taiao hoki te tae o ngā toka puia. He pānga nui tō rātou ki te kukume tae i ngā ika whakapaipai maha, pērā i a Arhat, i te Hōiho Whero, i te Kākā, i te Tarakona Whero, i a Sanhu Cichao, me ērā atu. Ina koa, ko te āhuatanga o Arhat ko te tata o tōna tinana ki te tae o ngā mea e karapoti ana. Mā te whero o ngā toka puia ka whero haere te tae o Arhat.

Ko ngā mahi a ngā toka puia e whā: te mimiti.
Ko ngā āhuatanga o ngā toka puia he pūngao me te whānui o te mata, ka taea te mimiti i ngā huakita kino i roto i te wai me ngā katote konganuku taumaha pērā i te chromium, te arsenic, tae atu ki ētahi toenga chlorine i roto i te wai e pā ana ki ngā rauropi. Mā te whakanoho i ngā toka puia ki roto i te aquarium ka taea te mimiti i ngā toenga kāore e taea te tātari e te tātari, me ngā paru hoki, kia noho ma ai te wai i roto i te tāke.

Ko te mahi a ngā toka puia he tākaro ki ngā taputapu.
Ko te nuinga o ngā ika, inā koa ko Arhat, kāore i te whakaranua, ka noho mokemoke hoki rātou, ā, he tikanga tā Arhat ki te tākaro ki ngā kōhatu hei hanga whare, nō reira kua waiho te kōhatu puia māmā hei taonga tākaro pai māna.
Ko te mahi a ngā toka puia he whakatairanga i te pākia o te tinana.

Ka taea e ngā huānga iti e tukuna ana e ngā toka puia te whakatairanga i te pākia o ngā pūtau kararehe me te kawe i ngā halide kino ki roto i te tinana, me te horoi i te paru i roto i ngā pūtau.
Te tūranga o ngā toka puia 7: te arotau i te tipu.
Ka taea hoki e ngā toka puia te whakapai ake i te hanganga pūmua i roto i ngā kararehe, te whakarei ake i te kaha ārai mate, ā, ki tētahi taumata, te whakanui ake i te nekenekehanga o Arhat. He mea nui anō hoki tēnei i te tīmatanga o Arhat.

Te Tūranga o te Kōhatu Puia 8: Te Ahurea o ngā Nitrobacteria.
He wāhi pai te horahanga o te mata nui e puta mai ana i te porosity o ngā toka puia hei whakatipu i ngā huakita nitrifying i roto i te wai, ā, he pai te utu o tō rātou mata, e āwhina ana ki te tipu pumau o ngā moroiti. He kaha te hydrophilicity o ēnei, ā, ka taea te whakapai ake i te kounga o te wai mā te huri i ngā momo take o te NO2 me te NH4 paitini ki te NO3 iti ake te paitini.

Te Tūranga o ngā Kōhatu Puia 9: Ngā Rauemi Matrix mō te Tupu o te Tarutaru Wai
Nā tōna āhua pūwero, he pai mō ngā tipu wai kia piki, kia whai pakiaka, kia mau ai ō rātou diameter. Ehara i te mea he pai anake ngā momo kohuke e rewa ana i te kōhatu mō te tipu o ngā ika, engari he tongi hoki mō ngā tipu wai. I roto i te mahi ahuwhenua, ka whakamahia te kōhatu puia hei papa mō te whakatipu kore oneone, hei tongi, hei tāpiri kai kararehe.

Te Tūranga o ngā Kōhatu Puia 10: Ngā Whakatakotoranga Noa me ngā Rahi Matūriki mō ngā Wai
Ngā whakaritenga rauemi tātari me te rahi o te matūriki: 5-8mm, 10-30mm, 30-60mm, e whakamahia whānuitia ana i roto i te hoahoa whenua: 60-150mm, 150-300mm. Ki te whakatauritea ki ētahi atu toka puia i Yunnan, he toka puia pakeke ngā toka puia o Tengchong me Shipai e whakamahia ana mō ngā rori, ngā piriti, ngā whare, me ētahi atu kaupapa. He pai ngā toka puia o Tengchong me Shipai i Yunnan, he mama, he nui te rahinga, he ahurei hoki te āhua.
