EKOLOGIYA
aralashmalar qo'shigan, hamda birlamchi fizik yoki kimyoviy 
xususiyatlari o'zgargan suvlar; turar joy punktiari, sanoat va 
qishloq xo'jalik hududlaridan. yog'in sochin, yerlar sug'orish yoki 
ko'chalarga suv sepish natijasida oqib cbiqadigan suvlar ham O.s. 
deyiladi. O.s. asosan 3 turga bo'linadi: maishiy (xo'jalik-fekal) 
oqavalar, ishlab-chiqarish oqavalari, qor erishi va jala (yomg’ir) 
oqovalari.
W aste w aters - waters used for domestic or industrial purposes 
and ortained the additional admixtures hereat changing an initial 
chemical composition or physical characteristics; waste is also 
called the waters flowing off territory o f the inhabited areas, 
industrial and agricultural plants as result of a deposition of 
precipitation, irrigation of lands or watering streets; there are 
distinguished three general categories of waste waters: domestic 
(households keeping and fecal), industrial (from economic 
activity), natural (from melted snow and heavy showers rains). 
O qava suvlarni tozalash - ifloslangan oqava suvlarni mexanik, 
fizik, kimyoviy va biologik va b. usullar yordamida har xil 
aralashmalardan tozalash.
T reatm ent of sewage - clearing sewage from various impurities 
with the help of mechanic, physical, chemical, biochemical and 
other methods of clearing.
O qavalarni biologik usulda tozalash - suv tozalashning keng 
qo'llaniladigan usullaridan biri: bunda suv sayoz hovuz va b. suv 
havzalarida organilc moddalarni saprobiont mikroorganizmlar 
yordamida minerallashtirish yo'li bilan tozalanadi.
Biological treatm ent of sevage - one of the most applicable 
methods of water treatment, at which it occurs the mineralization 
of organic substance by micro-organisms-saprobionts in shallow- 
water ponds and other reserviors.
