Ozone halaye:

Ozone (O3) shi ne isomorphic na oxygen (O2), shi ne mai karfi oxidant da kuma disinfectant. Ozone ya ƙunshi atom guda uku na oxygen a cikin triangle mai ƙwanƙwasa mai ƙwanƙwasa 2.144 kg / m3, wanda ke da ƙwanƙwasa fiye da sau 10 fiye da oxygen a cikin ruwa. Ozone oxidation ikon ne mai ƙarfi, da oxidation rage damar ne 2.08 V, da yawa fiye da ruwa tsire-tsire yawanci amfani da ruwa ruwa chlorine (oxidation rage damar ne 1.36 V).

Bayan zubar da ozone a cikin ruwa, amsawa tare da kayan kwayoyin ya raba zuwa amsawa kai tsaye da kuma amsawa a kai tsaye.

Amsa kai tsaye: Ozone kai tsaye oxidizes organic abubuwa a cikin ruwa, shi ne zaɓi, shi ne m amsa;

Amsa ta kai tsaye: Ozone an kafa shi ta ruwa ta hanyar · OH free radical oxide, ba shi da zaɓi, kuma yana amsawa da sauri.

Babban rawar Ozone a cikin tsarin tsabtace ruwa sune: kafin (pre) oxidation da kuma bayan oxidation.

Pre (pre) oxidation tsari:

A cikin pre (pre) oxidation tsari, aikin ozone ne mafi mahimmanci: cire ƙanshi da dandano, chromatography, baƙin ƙarfe, manganese da kuma nauyi karfe da algae, sa colloidal particles a cikin ruwa destabilize, inganta flocculation sakamakon, rage adadin da aka saka na mixer, da kuma iya cire mahaifiyar abubuwa kamar THM, rage abun ciki na abubuwa masu ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙarancin ƙaranc

Kafin (pre) Ozone tuntuɓar oxidation ne kaɗan adadin ozone, yawanci 0.5 ~ 1.5 mg / L. Lokacin amsawa yana da gajeren lokaci, yawanci 2 ~ 4 min, saurin amsawa, sauran ozone a cikin ruwa yawanci sifili ne ko kaɗan.

Post oxidation tsari:

A cikin tsari na post-oxidation, ozone yawanci ana amfani da shi tare da carbon mai aiki, aikinsa shine: kashe ƙwayoyin cuta da ƙwayoyin cuta; oxidizing organic abubuwa, kamar kashe kwari, tsaftacewa, phenols da sauransu; cire COD; Oxidation lalacewa chelates kamar EDTA da NTA da sauransu.

Bayan Ozone lamba oxidation amsawa saurin jinkiri, amsawa lokaci yawanci ba kasa da 10 min. Ozone sanya yawanci ne 1.5 ~ 2.5 mg / L, da sauran ozone a cikin ruwa ne 0.2 ~ 0.4 mg / L. Yin amfani da zurfin ruwa yana da 6 m.
