| Abstract: | The result of a simulation experiment on purification of salt and mercury containgwastewater using algae-artemia-prawn system showed that 95.5%and 80.8%of BOD5 andCOD and over 98%of PO and Hg2+ were removed.When artemia densities were 52.1and 36.0 ind./L with algae densities of 2.57×108 and 2.09×108 ind./L,the algae remov-ing ratios by artemia were 98.6%and 94.3%,respectively.The Hg in the water could beaccumulated by organisms in different nutrient levels. When the concentraltion of Hg was1.0×10-4 to 3.0×102mg/L, the concentration factors in algae and artemia were 7. 5×102to 7.8×103 and 2.1×102 to 1.04× 104.The Hg concentration factor in artemia was ratherlow,being 0.1-1.7.No evident of Hg accumulation in prawn was found. |
