MPC emanzini

Maximum lokuhlushwa kuvunyelwe (MPC) ka izinto ezilimazayo zixhunywe izenzo nesimo kuyinsakavukela sanitary iziqondiso. Ukwehluleka ukubona le mikhawulo ke Kuyicala okuyiwona umthwalo mthetho ngokuhambisana nomthetho. Isilinganiso MPC emanzini unika ticondziso mayelana amagugu komkhawulo ezingcolisayo, okuqukethwe okungadingi kuhilelani umonakalo empilweni noma ukuphila umuntu.

Imithombo eyinhloko izakhi ezinobuthi tisebenta eziningi zezimboni ibhizinisi eziyinkimbinkimbi. kwekhabhoni yabo ngokwanele kakhulu engcolisa umoya, umhlabathi namanzi. izakhi zamakhemikhali, okuyinto abe nomthelela omubi imvelo yethu, kungenziwa zihlukaniswe ngamaqembu ngokusho degree kwabo ingozi kubantu. Lezi zihlanganisa izinto nge ingozi:

- esiphuthumayo;

- okusezingeni eliphezulu;

- ngokulinganisela.

Kukhona iqembu izakhi eziyingozi.

MPC emanzini ezahlukene chemical lafakwe amatafula eziklanyelwe. Futhi, kukhona amafomula ezahlukene, ukusetshenziswa okwenza kube nokwenzeka ukubala umkhawulo ukubekezelelana ubuthi. Basuke esetshenziselwa ochwepheshe zokulawula i-amanzi ukusetshenziswa abantu. Izenzo ezinjalo zingase yimaphi lethu. Kwanele hlaziya isimo amanzi okuphuza ekhaya lakho bese uliqhathanisa nabazalwane kwezinkambiso kuvunyelwe lokuthola kuyo ezingxenyeni ezahlukahlukene. Ngokwesibonelo, okuqukethwe angu ilitha akufanele futhi iyophakama kuno-:

- ezisalayo ezomile - 1000;

- sulphate - 500;

- chloride - 350;

- zethusi - 1;

- zinc - 5;

- yensimbi - 0.3;

- manganese - 0.1;

- polyphosphate asalile - 3.5.

Inani nobulukhuni amanzi kumele singeqi angu eziyisikhombisa ilitha.

Kubaluleke kakhulu futhi ukulawula isimo inhlabathi. Lokho izwe ibhethri kanye lemifanekiso compounds ezahlukene. MPC angcolile, lapho kukhishelwa ngokuqhubekayo enhlabathini, kumelwe futhi ekuhambisaneni nale migomo, njengoba kufuduka njalo layo elingenhla izinto eziyingozi ngokwanele ingcolise ngokuqinile wonke imvelo.

Ngokusho kwezinkambiso enelanga, inhlabathi angase abe ngaphezulu:

- 0.02 mg / kg benzopyrene;

- 3 mg / zethusi kg;

- 130 mg / nitrate kg;

- 0.3 mg / kg toluene;

- 23 mg / zinc kg.

Uma sedlule lokuhlushwa kwamukelekile imizimba amanzi edingida kokulawulwa imvelo, ziyonquma Lo msindo ubangelwa. Kaningi, ukwanda isibalo ubunjalo chemical nomthelela jikelele imfucuza yasendlini. Okwamanje, inkinga yamanzi ukwelashwa sibi nakakhulu kusukela compounds phosphate kanye nitrogen. Ukuze ukuxazulula le nkinga, ungasebenzisa izindlela ezintathu ezahlukene:

- Chemistry;

- biology;

- iqoqo izindlela ezimbili zokuqala.

Ukwazisa zokulawula umkhawulo amagugu emanzini usebenzisa yokuhlanza chemical kuhilela kumiswa metalfosfatov okuyinto, ngokuba zingaxazululeki, axazulule phansi esitsheni akhethekile. Le nqubo ithatha indawo esebenzisa reagents. Ukusebenzisa amakhemikhali uhlanzekile indlela kabanzi lisetshenziswe izitshalo ezimbonini. Ekuqhubeni le misebenzi kungaba izisebenzi kuphela abaqeqeshiwe.

Lapho usebenzisa i-wali band noma P-bacterium, le ndlela ngesikhathi ukuhlanzwa begazi amanzi. Kuyinto yesimanje, indlela yemvelo ukuvimbela esiphezulu lokuhlushwa kuvunyelwe. izindawo ezikhethekile yokwelashwa amathangi bephethe kushintshana amagciwane aerobic kanye anaerobic. Le ndlela isetshenziswa biofilters, amathangi ukonakala futhi aeration amathangi.

Iqoqo izindlela begazi futhi chemical isetshenziswa ekwelashweni amanzi izinhlelo lapho kunendingeko ukusheshisa futhi kuthuthukise noqhekeko ukuphendula amanyela.
