CODcr

基本解釋

CODCr removal ratio of DSD acid reduction wastewater was over 74.7% at appropriately operating conditions.
通過(guò)樹(shù)脂選型確定出大孔弱堿性陰離子交換樹(shù)脂D301R;其對(duì)廢水COD_(Cr)的去除率可達(dá)74.;7%25。
CODcr abd BOD_5 in the effluent were less than 100mg/l and 50mg/l respectively after secondary treatment.
經(jīng)兩級(jí)處理后的出水;COD_(Cr)
ATC waste liquid has such characteristics as high CODcr, high salinity and nonbiodegradable.
ATC廢液具有高COD,高含鹽量，以及難生物降解的特點(diǎn)。
CODcr went beyond 2nd standard of sewage treatment plant a little in water quality without effective composite bacteria,while O3=0.24gO3/gMLSS.
未投加高效復(fù)合菌時(shí)出水COD_(Cr)略超出污水處理廠二級(jí)出水水質(zhì)標(biāo)準(zhǔn)，此時(shí)O_3量為0.;24gO_3/gMLSS；
A simple and rapid method of estimation of the dilution ratio in BOD 5 determination based on the CODcr values is proposed in this paper.
在生化需氧量 (BOD5)的測(cè)定中 ,稀釋倍數(shù)的估計(jì)是否適當(dāng)至關(guān)重要。
