- Abstract:
- In order to solve the problem of biological slime growth in circulating cooling water of power plants, the treatment performance of three kinds of typical biological enzymes with different mass ratio on biological slime was investigated. The compound enzyme with α-amylase, trypsin and lysozyme ratio of 2 ∶1 ∶1 had the maximum removal efficiency of biological slime, which was (30.49±1.46)%, and αamylase played an important role in the removal of biological slime. The compound enzyme with α-amylase, trypsin and lysozyme ratio of 1 ∶1 ∶2 reduced the activity of biological slime by (61.70±3.81)%, and lysozyme was important in the reduction of biological slime activity. Scanning electronic microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and energy dispersive spectroscopy (EDS) images showed that biological enzyme could degrade proteins and polysaccharides of biological slime so as to remove biological slime and lysozyme could inactivate bacteria so as to inhibit the activity of biological slime.
