The results of operation shows that when the average concen tra tion of inflow COD (cr),BOD 5 and ss are 1973 mg/L,787mg/L,1049mg/L,the out flow are 206 mg/L,89mg/L and 102mg/L,respectirely. The quality of water accords with the second grade of the comprehensive Effluent Discharge Standard(GB 8978-1996) after treatment.
Results The quality of water showed no significant influence on the expression of OP-1. The optimal inoculum amount and initial pH value for rhOP-1 expression were 2%-4% and 6.0 respectively.
Third, ecological water requirements are related to a multiple system including water quality, water quantity, and time and space, which interact with each other.
At present, the 1st stage cleaning cycle by Cleaner A and Cleaner C is conducted every 100 and 500 h, respectively, depending on raw the water quality.
Some theoretical issues and implementation details about the algorithm are discussed, including the solution of the pricing subproblem, the quality of LP relaxations, the branching scheme as well as the column management.
Seven topological descriptors are finally selected from 127 topological descriptors by GAPLS method to build a QSRR model with a high regression quality of squared correlation coefficient (R2) of 0.99998 and standard deviation (S) of 2.88.
The water-soluble glucan was obtained from Pleurotus florida fruit bodies by hot water extraction, ethanol precipitation, DEAE cellulose dialysis and Sephadex G-75 gel filtration.
Methanol extracts demonstrated better inhibitory effects on cultured L929 cells followed by purified berberine from cell suspension cultures and water extracts.
The activity of acid phosphatase of some freshwater mollusks was examined and correlated with the quality of water in the laboratory experiment and in their natural habitats.
The conclusion is drawn that the Selenga River water flowing from the territory of Mongolia cannot directly affect the quality of water in Lake Baikal.
An ecological and hydrochemical classification elaborated by the authors is used to assess the present quality of water in the most important water objects of the Republic of Armenia.
