Sanoat korxonalarining atrof-muhitga ta’sirini baholash


Ishdan maqsad: Sanoat korxonalarining atrof-muhitga ta’sirini baholashni o’rganish.
Korxonalarning atmosferasini umumiy ifloslanishidagi ishtirok etish darajasi bo’yicha sinflash maqsadida quyidagi ko’rsatkichlar kiritiladi:
Zaharli chiqindi moddalar yig’indisi sifatida va kishi boshiga, har bir chiqarib tashlanadigan chiqindilarning xavflilik yoki zaharlilik darajasiga va ifloslantirish manbasiga qarab ularning birlik yuzadan chiqadigan solishtirma miqdori. Bu balans usuli kundalik chiqadigan zararli moddalarning miqdorini aniqlashga, qaralayotgan maydondagi “solishtirma ekologik ta’sirini” va “energiya tejamkorlik” miqdorini o’rganish imkonini beradi.
Masala 2: korxonada xom ashyolarni tayyorlash bo’limida moslamalardan chiqayotgan chang miqdori F=5,0 g/s quvvat va t=25,5⁰C harorat bilan ventilyastion sistema orqali atmosferaga chiqib ketadi. Chiqindilar w=7,5 m/s tezlik bilan, balandligi H=16 m va diametri D=0,6 m bo’lgan quvurdan chiqarib yuboriladi.


V=F·D (1)
H
F=1000·W²·D (2)
H²·T
Havoga chiqadigan chang konstentrastiyasi aniqlash lozim – S chang.
Atmosfera havosiga baho bering.
REM chang=1mg/m³ deb qabul qilinsin.


Hisoblash.
F=5,0 g/s, T=25,5^0C, W=7,5 m/s, H=16 m, D=0,6 m


Masalani echilishi:
V=FD/H=5·0,6/16=0,19 m
F=1000·W²·D/H²·T=1000·7,5²·0,6/16²·25,5=33750/6528=5,2 m/s

Olingan natijalar shuni ko’rasatadiki, sanoat korxonalaridan chiqayotgan zaharli moddalar miqdori atmosfera va atrof muhitga ta’siri juda yuqoridir.

Zaharli chiqindi moddalar yig’indisi sifatida va kishi boshiga, har bir chiqarib tashlanadigan chiqindilarning zaharlilik darajasiga va ifloslantirish manbasiga qarab ularning birlik yuzadan chiqadigan solishtirma miqdori aniqlandi. Bu balans usuli kundalik chiqadigan zararli moddalarning miqdori aniqlandi.
