Mmepe na Ngwa
Ụwa Diatomaceous, n'ihi njirimara physicochemical pụrụ iche, ejirila ya mee ihe dị ka ihe enyemaka nzacha, ihe na-arụ ọrụ, onye na-ebu ihe, pesticide na fatịlaịza, ihe mkpuchi, adsorbent na ihe ịcha ọcha.
Enyemaka nzacha:
Enwere ike iji ụwa Diatomaceous mee ihe enyemaka nzacha na nri, ọgwụ na ụlọ ọrụ gburugburu ebe obibi. Dịka ọmụmaatụ, iji diatomaceous earth filtration na usoro mmanya nwere ike na-aga n'ihu na-emelite akwa nzacha, ngwa ngwa nzacha ngwa ngwa, nnukwu mkpụrụ ; Site na nnukwu elu na ikike adsorption siri ike, ọ nwere ike nyochaa ihe ndị sitere na 0.1 ruo 1.0 μm. belata mmanya na-aba n'anya ihe dịka 1.4%, ma melite ọnọdụ nrụpụta ọrụ. Ihe nzacha ụwa nke Diatomaceous nwere ike melite ogo mmiri nke ọdọ mmiri na-ekesa ọgwụgwọ mmiri, ma nwee ike ịchekwa mmiri na ọkụ eletrik na ọrụ na njikwa nke ọdọ mmiri. Nke abuo, ụwa diatomaceous ejirila ya mee ihe n'ọtụtụ ebe na mmanụ oriri, mmiri ọgwụ ọnụ na-emepụta ọgwụ, na ubi ndị ọzọ.
Adsorbent:
A na-eji ụwa Diatomaceous eme ihe n'ọtụtụ ebe na ọgwụgwọ mmiri mkpofu n'ihi njirimara kemịkalụ ya kwụsiri ike, ikike mgbasa ozi siri ike, arụmọrụ filtration dị mma na enweghị ike na acid ọ bụla siri ike. Tupu ọgwụgwọ nke leachate ahịhịa na-eji diatomaceous earth flocculation usoro nwere ike ibibi CODCR na BOD5 na leachate ahụ, wepụ ihe ndị na-emerụ emerụ dị ka SS, a na-ejikarị ya eme ihe maka mmiri mkpofu obodo, na-ede akwụkwọ mmiri, ibipụta na ịcha mmiri, igbu mmiri mmiri, mmiri mkpofu mmanu mmanu. , na mmiri mkpofu ígwè dị arọ.
