BOD Tester

WanzeruBOD Tester

BOD biochemical oxygen demand tester ikugwirizana ndi muyezo wadziko lonse wa "HJ505-2009" njira yoyamwitsa yamasiku 5, kutengera kuwononga kwachilengedwe kwa zinthu zachilengedwe, pogwiritsa ntchito njira yosavuta, yotetezeka komanso yodalirika ya mercury yopanda kusiyanasiyana kutengera mphamvu. BOD m'madzi; mamangidwe anzeru mokwanira, kutsogolera kafukufuku ndi chitukuko ndondomeko ndi mapangidwe ndi kupanga, ndondomeko kuyesera popanda kufunikira ndodo experimental kulonda; zogwiritsidwa ntchito m'mabizinesi onyansa, kuyang'anira zachilengedwe, malo opangira zimbudzi, mabungwe oyesa anthu achitatu, kafukufuku wasayansi, mayunivesite ndi magawo ena. Ndi oyenera mabizinesi zimbudzi, kuwunika chilengedwe, zomera zinyalala, mabungwe kuyezetsa gulu lachitatu, kafukufuku wasayansi, makoleji ndi mayunivesite ndi madera ena a biochemical mpweya amafuna muyeso.

Pmawonekedwe a njira:

1. Zitsanzo zisanu ndi chimodzi zimatha kuyesedwa nthawi imodzi;

2.* Malo asanu ndi limodzi oyesera odziimira okha, magulu atsopano oyezera amatha kuwonjezeredwa nthawi iliyonse panthawi yoyesera;

3. Kuwerenga kwachindunji kwa mtengo wamtengo wapatali wa BOD, palibe chifukwa chowerengera;

4. Non-mercury differential pressure design, kulondola kwambiri, popanda kutembenuka, ndi kuonetsetsa chitetezo ndi thanzi la oyesera;

5. Palibe kapangidwe ka mapaipi mu ulalo woyeserera, kupewa kukalamba kwa mapaipi, kutayikira kwa mpweya ndi zovuta zina;

6. Miyezo yoyezera ndiyosankhika, ndipo palibe kuchepetsedwa komwe kumafunikira ngati kuchuluka kwa zitsanzo zamadzi kumakhala kotsika kuposa 4000mg/L;

7. Chida choyezera chimangolemba deta yoyezera, kuyesa kuyesa kungasankhidwe kuchokera ku 60 sampuli, deta yolondola yodziwira;

8. Kuzungulira kwa incubation kungasinthidwe, malinga ndi zofunikira zomwe zingasankhidwe;

9. Malizitsani zokha zoyezera, osafunikira kukhala ndi anthu;

10. Chiwonetsero chachikulu chamadzimadzi chamadzimadzi, chowoneka bwino komanso chomveka, chosavuta kusankha polojekiti;

11. Malo oyesera amabwera ndi batri lamphamvu kwambiri, moyo wa batri wa zaka zoposa 2, ndondomeko yoyesera sichimakhudzidwa ndi kutha kwa magetsi kwa nthawi yochepa m'madera akunja.
