| Abstract: |
| A principle, which has usually been applied to biochemical treatment for waste water is presently introduced into the study on marine microbiological ecology and employed in the estimation of environmental capacity.By means of a selection of 3 models for the microbial growth or for its oxygen consumption and determinations of concerned parameters in the field and the laboratory, the environmental capacity for the Restern Xiamen Harbour is evaluated to be 37 t·d-1 of BOD5 in gross or 28 t·d-1 in net (with some 2500 of the gross capacity consumed by a present ecosystem) if BOD5 is controlled without excess of 3 mg·dm-3 in the sea water; it means that an amount of domestic waste water equal to 28 t of BOns can be naturally self-purified in this sea area everyday.Furthermore it is found that the K value, a constant of oxygen-consumed kinetics, shows possitive correlation to the concentration of BOD5 in the same system and total bacterial number (TB) in the seawater also to BOD5 with a regression equation TB (108 dm-3)=9.91×BOD5 (mg·dm-3)+1.74 (n=32.r=0.544 1, p<0.01). |
