【 摘 要 】

Combined purification system of microorganism - aquatic plants were established by adding immobilized 3.0 × 1010 CFU/m3 EM (Effective Microorganisms) to Eichhornia crassipes and Pistia stratiotes, to study the purification effect on prawn aquaculture water. The results showed that the purification effect of 2 groups of immobilized microorganism - aquatic plants (SEE and SEP) on ammonia nitrogen (NH4 +-N), total nitrogen (TN), total phosphorus (TP) and chemical oxygen consumption (COD) were significantly better than those of the immobilized microorganism SEM group (P
