Abstract

A new kind of compounded microbial flocculant (CMBF) for water and wastewater treatment has been developed through biological technology. The compounded microbial flocculant (CMBF) have been used in treatment of the Songhua River in this experiment. At the same time, In order to discuss its biological security, four groups of experiments, rat acute toxicity test via mouth, salmonella assay in vitro, mouse micronucleus in vivo test and teratogenesis test were conducted to evaluate its general toxicity, genotoxicity and generative toxicity. It can be inferred that the complex flocculant is efficient in the removal of turbidity of raw water. The experimental results showed that this type of compounded microbial flocculant was a substantial non-toxic substance based on the fact that LD50 value was over 10mg/kg. The results from salmonella in vivo test and mouse micronucleus in vivo test revealed that the compounded microbial flocculant is a genetically non-toxic substance. Furthermore, compounded microbial flocculant has little effect on the growth of all the rats, and any morphologic abnormal phenomenon hasn't appeared.
