1. Urban sewage
The treatment of domestic sewage with a highly efficient mixed flora with flocculation and degradation separated from municipal sewage can achieve a COD and BOD removal rate of 100%.
2. Building materials wastewater
The former mainly contains a lot of clay particles, and the latter has a considerable amount of glaze in addition to the clay particles. 5 minutes after the addition of NOC-1, the turbidity of the body waste water decreased from 1.4 to 0.043; the turbidity of the glaze wastewater decreased from 17.2 to 0.35; the turbidity removal rates were 96.6 % and 79.9%, respectively, which was almost transparent. The supernatant was treated with a flocculant produced by Rhodococcus erythropolis to treat the wastewater of the plant, and the treated supernatant was almost transparent.
3. Other applications
Due to the safe and non-toxic properties of microbial flocculants, they are gradually adopted in the treatment of food wastewater and have achieved satisfactory results. In addition, microbial flocculants can be widely used in many aspects such as urban sewage, hospital sewage, petrochemical wastewater, papermaking waste liquid, pharmaceutical wastewater.
High efficiency and residual amount no longer cause 2 pollutions, which is an important direction for the development of flocculant research in the future. Safe, non-toxic and high-efficiency microbial flocculants have a tendency to replace traditional flocculants.
