Nzọụkwụ mbụ n'ime ntinye aka nke diatomite filter filter na titanium filtration bụ mkpuchi mkpuchi, nke pụtara na tupu arụ ọrụ titanium filtration, a na-etinye ihe nzacha diatomite na nzacha nzacha, ya bụ, akwa akwa. A na-akwado diatomite n'ime nkwusioru n'otu akụkụ (n'ozuzu 1∶8 ~ 1∶10) na tankị mkpuchi mkpuchi, mgbe ahụ, a na-agbanye nkwusioru ahụ n'ime mpempe akwụkwọ nzacha jupụtara na mmiri doro anya ma ọ bụ na-agbanye site na mgbapụta mkpuchi mkpuchi, na mgbasa ozi ugboro ugboro (ihe dịka 12 ~ 30min) ruo mgbe mmiri na-ekesa doro anya.

N'ụzọ dị otú a, a na-emepụta precoating na-ekesa n'otu n'otu na ihe nzacha (akwa akwa). Iji kwadebe nkwusioru, na-ejikarị mmiri doro anya, mana nwekwara ike iji mmiri mmiri titanium doro anya. Ọnụ ego nke diatomite eji eme ihe maka mkpuchi mkpuchi bụ n'ozuzu 800 ~ 1000g / m2, na ọnụ ọgụgụ kachasị elu nke mkpuchi mkpuchi ekwesịghị gafere 0.2m3 / (m2? H). Precoating bụ isi nzacha akwa maka titanium mmiri mmiri filtration, na àgwà ya na-metụtara kpọmkwem ihe ịga nke ọma nke dum filtration okirikiri.

Mkpuchi mkpuchi kwesịkwara ịṅa ntị na isi ihe ndị a:

(1) N'oge mkpuchi mkpuchi, ọnụọgụ diatomite kwesịrị ịbụ 1 ~ 3mm nzacha oyi akwa. N'iji ahụmịhe nke ụlọ ọrụ mmepụta ihe dị ka ihe atụ, a na-eji efere 80m2 na mpempe akwụkwọ ntanetị, na 100kg nke enyemaka nzacha diatomite na-agbakwunye oge ọ bụla n'oge mkpuchi mkpuchi, nke nwere ike nyochaa na-aga n'ihu maka 5d ma mepụta 17-18T nke ngwaahịa emechara kwa ụbọchị.

(2) Mgbe ị na-ekpuchi ihe, efere na ihe nzacha nke etiti ga-ejupụta na mmiri mmiri tupu oge eruo, a ga-ahapụkwa ikuku n'akụkụ elu nke igwe;

(3) mkpuchi mkpuchi kwesịrị ịnọgide na-akụ okirikiri. N'ihi na a naghị emepụta achicha nzacha na mmalite, ụfọdụ ihe ndị dị mma ga-agafe na akwa nzacha wee banye nzacha. Mgbasa ahụ nwere ike igbochi ụmụ irighiri ihe ndị a kpochara n'elu achicha nzacha ọzọ. Ogologo oge okirikiri na-adabere n'ogo doro anya achọrọ maka nzacha.

Nzọụkwụ nke abụọ bụ ịgbakwunye filtration. Mgbe a na-ehichapụ mmiri mmiri titanium nke nwere ihe siri ike na colloid adịghị ọcha, mgbe emechara ihe mkpuchi ahụ, ọ dịghị mkpa ịgbakwunye enyemaka nzacha diatomite iji nzacha ozugbo. Mgbe ị na-enyocha mmiri mmiri titanium nke nwere ihe ndị siri ike na colloidal adịghị arụ ọrụ, ma ọ bụ mgbe a na-enyocha mmiri titanium na nzacha dị elu na viscosity, a ga-agbakwunye ihe enyemaka nzacha diatomite kwesịrị ekwesị na mmiri mmiri titanium nzacha. Ma ọ bụghị ya, a ga-ekpuchi elu nke mkpuchi mkpuchi ahụ na adịghị ike siri ike na colloidal n'oge na-adịghị anya, na-egbochi ọwa nzacha, nke mere na nrụgide nrụgide n'akụkụ abụọ nke achicha nzacha ga-ebili ngwa ngwa, na usoro nzacha ga-adị mkpụmkpụ.
