Study for High-Efficient Microbial Flocculent and its Application in Wastewater Treatment

Objective: More and more non-degradable substances in wastewater along change of life style, however, traditional handling agent has not met the demand of wastewater treatment, so it is very important to study for new highefficient flocculent. Method: Sifting out six microbes after testing and inoculation, and then testing for wastewater quality having three contents, this found that mix bacteria had better effect than 1# microbe at time of separate use, mix bacteria 1# microbe are dominant, and also discussed with external advantage influencing on flocculent. Conclusion: 1# microbe has the best effect of flocculent for three wastewater, respectively as 91.2% (A wastewater), 80.5% (B wastewater) and 80.5 % (C wastewater).
