JAVNA ODVODNJA U 2009.
PUBLIC SEWAGE SYSTEM, 2009
|
U 2009. ukupna
količina otpadnih voda iznosila je 324 781 000 m3.
|
|
In
2009, the total volume of waste waters amounted to 324 781 000
m3.
|
|
|
|
|
|
Od ukupne količine
otpadnih voda 226 916 000 m3 činile su vode iz kućanstava i
gospodarskih djelatnosti (smanjenje za 1%), dok se 97 865 000
m3 odnosilo na ostale vode (padaline i dr.).
|
|
Out
of the total volume of waste waters, 226 916 000 m3 were from households and
economic activities (decrease of 1%), while 97 865 000 m3
were other waste waters (precipitations etc.).
|
|
|
|
|
|
Ispuštanje otpadnih
voda iz kućanstava bilo je na nižoj razini za 1%, a u gospodarskim
djelatnostima bilo je zabilježeno smanjenje za 1%.
|
|
The
volume of waste waters discharged from households as well as that
discharged from economic activities decreased by 1% each.
|
|
|
|
|
|
U
2009. bilo je 206 042 000 m3 pročišćenih
otpadnih voda, što je 7% više od ukupne količine pročišćenih otpadnih voda
u odnosu na prethodnu godinu. U 2009. bio je nastavljen pozitivan trend
povećanja kvalitete pročišćavanja koji je bio izražen u povećanju udjela
prvostupanjskog pročišćavanja (za 10%) i drugostupanjskog pročišćavanja (za
6%).
|
|
In
2009, there were 206 042 000 m3 of treated waste waters, which made 7%
more out of the total volume of waste waters. A positive trend of
increasing the quality of treating continued in 2009 as well, which was
expressed in the increase of the share of primary treatment (by 10%) and
secondary treatment (by 6%).
|
|
|
|
|
|
Iz strukture
ispuštanja otpadnih voda vidi se da ih se najviše ispuštalo u vodotoke (76%
nepročišćenih i 77% pročišćenih otpadnih voda) i more (21% nepročišćenih i
22% pročišćenih otpadnih voda).
|
|
The
structure of discharged waste waters showed that the most waste waters were
discharged into watercourses (76% of untreated and 77% of treated ones) and
into the sea (21% of untreated and 22% of treated ones).
|
|
|
|
|
|
U 2009. kanalizacijska mreža bila je duga 8 144 km, što je za 6% više od prethodne godine. To povećanje vidi se pri gradnji novoga općeg
sustava i novoga separacijskog sustava.
|
|
In 2009, the sewage network was 8 144 km long, which was by 6% more than in the previous year. This increase was shown at the
construction of a new general system and a new separation system.
|
|
|
|
|
|
Broj kanalizacijskih
priključaka u odnosu na prethodnu godinu povećan je za 5% i iznosio je 435
607. Ukupan broj uređaja za pročišćavanje otpadnih voda bio je 103, što je
smanjenje za 5%. U strukturi se najviše povećao broj uređaja za
prvostupanjsko pročišćavanje (za 10%), koji su pridonijeli spomenutom
povećanju kvalitete pročišćavanja.
|
|
As
compared to the previous year, the number of sewage connections increased
by 5% and amounted to 435 607. The total number of waste water treatment
plants was 103, which was a decrease of 5%. In the structure of treatment
of waste waters, the greatest increase was recorded in the number of the
primary treatment plants (10%), which contributed the most to the mentioned
increase of treatment quality.

Statističko
istraživanje provodi se na osnovi potpunog obuhvata, a izvor za izradu
adresara jest Registar poslovnih subjekata. Istraživanjem se dobivaju
osnovni podaci o otpadnim vodama, njihovu pročišćavanju i ispuštanju te o
kanalizacijskoj mreži i uređajima za pročišćavanje otpadnih voda. Istraživanje VOD-2K provodi se na temelju Programa statističkih
aktivnosti Republike Hrvatske 2008. -2012.
|
|
Statistical surveys
are based on the full coverage and the source for the address list is the
Register of Business Entities. The survey provides basic information on
waste waters, their treatment and discharging as well as on the sewage
network and waste water treatment plants. The VOD-2K Survey is based on the
Programme of Statistical Activities of the Republic of Croatia 2008 – 2012.

Definicije
|
|
Definitions
|
|
|
|
|
|
Otpadne vode jesu vode koje se
nakon korištenja tretiraju kao otpadne vode i odvode do uređaja za
pročišćavanje ili se ispuštaju u prostor (u podzemne ili površinske vode).
Ovdje su uključene i atmosferske vode.
|
|
Waste waters are waters that are
considered waste ones after use. They are drained to the treatment plants
after use, or discharged into the environment (into ground or surface
waters). They include atmospheric waters as well.
|
|
|
|
|
|
Pročišćene otpadne
vode
jesu dio otpadnih voda koji se pročišćava prvostupanjski, drugostupanjski i
trećestupanjski.
|
|
Treated waste water comprises all amounts
of waste water that were treated by using either primary (mechanical),
secondary (biological) or tertiary (combined) treatment method.
|
|
|
|
|
|
Prvi stupanj
pročišćavanja jest primjena fizikalih i/ili kemijskih postupaka čišćenja
otpadnih voda kojima se iz otpadnih voda uklanja najmanje 50% suspendirane
tvari, a vrijednost BPK5 smanjuje barem za 20% u odnosu na vrijednosti BPK5
u ulaznim vodama (influenta).
|
|
The primary treatment
includes the application of physical and/or chemical processes by which at
least 50% of suspended solids are removed from the waste water, while the
BOD5 value decreases as much as 20%, as compared to its value in
the influent waters.
|
|
|
|
|
|
Drugi stupanj
pročišćavanja jest primjena bioloških i/ili drugih postupaka čišćenja
kojima se u otpadnim vodama smanjuje koncentracija suspendirane tvari i BPK5
influenta za 70 – 90%, a koncentracija KPK za najmanje 75%.
|
|
The secondary
treatment includes the application of biological and/or other treatment
processes by which the concentration of suspended solids and BOD5
decreases by even 70% to 90% and the concentration of COD by at least 75%.
|
|
|
|
|
|
Treći stupanj
pročišćavanja jest primjena fizikalno-kemijskih, bioloških i drugih
postupaka kojima se u otpadnim vodama smanjuje koncentracija hranjivih
tvari influenta za najmanje 80%, odnosno uklanjaju i drugi posebni
pokazatelji otpadnih tvari u granicama vrijednosti koje nije moguće postići
primjenom drugog stupnja pročišćavanja.
|
|
The third treatment
includes the application of physical and chemical, biological and other
treatment processes by which the concentration of nutritious matters in
influent waste waters decreases by as much as 80%, which means that other
pollutants, which could not be removed to that extent in the secondary
treatment, are now removed as well.
|
|
|
|
|
|
Javna kanalizacijska
mreža jest mreža zatvorenih uličnih kanala i kolektora koja služi za
zajedničko odvođenje otpadnih i atmosferskih voda (opći sustav
kanalizacije) ili kao posebna mreža za odvođenje otpadnih voda, a posebno
za odvođenje atmosferskih voda (separacijski sustav kanalizacije). U
duljinu kanalizacije ne ulazi duljina priključaka i mreža po kućama.
|
|
Public sewage system
is a network of enclosed public drains and sewers used either for draining
of both waste and atmospheric waters together (general water sewage
system), or for separate draining of waste and atmospheric waters (separation
water sewage system). The length of sewage system does not include the
length of connections and networks within buildings.
|
|
|
|
|
|
Glavni kolektor jest
sabirni kanal koji odvodi vode iz jednog dijela ili cijeloga grada do
recipijenta ili uređaja za pročišćavanje.
|
|
Main sewer is a
collecting drain that drains water from one part or the whole city to the
recipient or to the treatment plant.
