bezarargardonii-obBEZARARGARDONII OBI NuSHOKi, tadbirhoi sanitariyu tekhnikiest, ki baroi nest kardani angezandai bemorihoi siroyatii ob (beshtar obi nushoki) peshbini shudaand. Obi nushokiro bo moddahoi khimiyavi (mas., khlor, ozon, yod, ionhoi nuqra) yo usulhoi fiziki (jushonidan, tavassuti afkanishoti ultrabunafsh, ultrasado, gamma-afkanishot) bezarar megardonand. Holo usuli khlornok kardani ob tavassuti payvasthoe, ki khlori faol dorand, farovon istifoda meshavad. Dar manbahoi obrasoni bo in maqsad az khloratorhoi makhsus istifoda mebarand.
Hlorzani usuli yagonai gandzudoii obi choh ast. Bo in maqsad avval obi chohro tamoman girifta, onro az loyqa toza mekunand. Badi to sathi muqarrari pur shudani obi choh ba on ohaki khlornok meposhand. Miqdori zarurii ohaki khlornokro az hisobi 100 – 150 mg khlori faol ba 1 l ob az rui chunin formula muayyan mekunand:
P=
P – miqdori zarurii ohaki khlornok; E – hajmi obi choh ba hisobi m3 (bo rohi ba chuqurii hajmi ob zarb zadanii sathi burishi choh muayyan mekunand); C – gilzati khlori faol dar obi choh ba hisobi mg/l yo g/m3; H – miqdori khlori faoli ohaki khlornok ba hisobi 1 : 100 – koeffitsienti doimii adadi. Mas., ohaki khlornok 25% khlori faol dorad; baroi 3 m3 ob miqdori ahaki khlornokro az hisobi 150 g khlori faol ba 1 m3 hisob mekunem:
P= =1800 g.
Ohaki khlornokro bo kame ob dar satil yo yagon zarfi digar hal (1 : 2 – 3) namuda, sipas ba choh merezand va 15 daq. bo obi choh meomezand; bad chohro rust mekunand va muddati 6 soat ob namegirand. Agar ob bui khlor nadoshta boshad, boz choryak yo seyaki miqdori avvalai ohakro ba ob hamroh karda, badi 3 – 4 soat onro baroi ruzgor istifoda mebarand.
Bo ozon niz obro bezarar kardan mumkin. Az rui khulosai mutakhassison chunin ob gayr az bezarar budanash berangu bebuy niz meshavad.
Bo maqsdai B.-i individulai moddahoi khimiyavii khosiyati balandi bakterisidi doshtaro niz kor mefarmoyand. Onho badi 15 – 20 daq. obro besiroyat karda, baroi odam zarar nameorand. Baroi in beshtar pantosid istifoda meshavad (dar 0,5 – 0,75 l ob 1 dona qursi onro hal mekunand). Dar surati az had ziyod iflos budani ob du dona qursi pantosid meandozand. Hini istemoli pantosid mazzai ob tagyir nameyobad. Jushonidani ob az qabili usulhoi mamuli oddi va boetimodi B. ast. Zimni on gayr az mahv gashtani bakteriyahoyu mikrobho, durushtii ob kam meshavad.
